Description

Technical Field

[0001] This application belongs to the technical field of bicycle processing equipment, and in particular relates to a production process and apparatus for bicycle rims. Background Technology

[0002] In the manufacturing process of bicycle wheels, a large number of holes need to be evenly distributed on the outer circumference of the hub to facilitate the connection between the hub and spokes. Currently, the drilling method for hubs has replaced traditional manual drilling, and semi-automatic and automated drilling equipment are now primarily used for the drilling process.

[0003] Chinese patent CN215786892U discloses a bicycle wheel hub drilling device, which includes a base and a drilling device. A control cabinet is installed on the base, and a processing table is installed on the upper end of the base. A wheel hub positioning plate is installed at the center of the processing table. The drilling device is evenly arranged around the wheel hub positioning plate. A circular plate is installed at the center of the wheel hub positioning plate. Multiple radial slide rails are evenly arranged around the wheel hub positioning plate located on the outer periphery of the circular plate. Each radial slide rail is equipped with a sliding top rod. The outer end of the sliding top rod is equipped with a wheel hub holder, and the inner end is connected to the circular plate by a movable rod.

[0004] Although the aforementioned drilling equipment can perform drilling on wheel hubs, the large number of holes on the hubs results in a significant amount of debris after each machining operation, which is distributed across the machining table and affects subsequent machining processes. Summary of the Invention

[0005] The purpose of this application is to address the aforementioned technical problems by providing a production apparatus for bicycle rims that reduces the accumulation of iron filings on the processing table and improves the cleanliness of the processing environment.

[0006] This application provides a production apparatus for bicycle rims, comprising:

[0007] Processing table surface;

[0008] A drilling device for drilling holes in an iron ring, the drilling device including a drill bit and a brush head;

[0009] A clamping device for clamping an iron ring, the clamping device comprising an inner clamping block and an outer clamping block;

[0010] A chip collection device is used to collect iron filings generated during drilling. The chip collection device includes a negative pressure device and a chip collection box.

[0011] A drive unit is mounted on the processing table, and the drive unit is connected to the clamping device.

[0012] The clamping device moves in the same direction as the radial direction of the iron ring. The clamping device is provided with a chip suction chamber, which is placed on the inner clamping block and the outer clamping block. The drilling device is placed in the chip suction chamber of the inner clamping block. The clamping device is provided with a chip discharge channel, which is connected between the chip suction device and the chip suction chamber.

[0013] The workpiece is clamped by a clamping device. Both the inner and outer clamping blocks are adapted to the workpiece. A drive device is used to move the inner and outer clamping blocks. Both the inner and outer clamping blocks are equipped with chip suction cavities. A drilling device is installed in the chip suction cavity. The iron chips generated by drilling fall into the chip suction cavity. Then, a negative pressure device sucks the iron chips in the chip suction cavity and collects them in the chip collection box through the discharge channel, ensuring the cleanliness of the worktable and reducing the labor intensity of workers cleaning the worktable. Both the inner and outer clamping blocks are equipped with drilling devices. The drilling device on the inner clamping block is used to drill holes for machining through holes in the workpiece. The drilling device on the outer clamping block is equipped with a brush head for removing burrs from the edges of the through holes. The drive device clamps all the inner and outer clamping blocks simultaneously, increasing the clamping speed and improving the workpiece processing efficiency.

[0014] Furthermore, the clamping device includes:

[0015] Fixed sealing ring;

[0016] The movable sleeve is placed inside the dust collection chamber and fits the inner wall surface of the dust collection chamber;

[0017] Elastic membrane;

[0018] The air intake channel is connected to the dust collection chamber;

[0019] A dust-shaking mechanism is used to shake off impurities from an elastic membrane.

[0020] The first drive cylinder is used to drive the movable sleeve to move;

[0021] The second drive cylinder is used to drive the drilling device to move.

[0022] A stabilizing mechanism is installed between the drilling device and the movable sleeve;

[0023] The movable sleeve is provided with an inflation chamber, and the elastic membrane is installed at the opening of the inflation chamber.

[0024] A fixed sealing ring is placed around the periphery of the chip suction chamber. By abutting against the workpiece, the sealing performance between the inner and outer clamping blocks and the workpiece is increased, preventing iron filings and dust from escaping through the gap between the clamping blocks and the workpiece. Air enters the chip suction chamber through the air inlet channel, facilitating gas flow and transporting the iron filings in the chamber to the chip collection box. The negative pressure in the chip suction chamber and the structure of the fixed sealing ring enhance the clamping effect between the inner and outer clamping blocks and the workpiece, improving the stability of the workpiece during machining. A movable sleeve is movably installed in the chip suction chamber. The movable sleeve is driven to move by the first drive cylinder. An elastic diaphragm is installed on the movable sleeve, and air is filled in the inflation chamber, causing the elastic diaphragm to bulge outwards. When the movable sleeve moves toward the workpiece, it brings the elastic membrane against the workpiece, improving the tightness of the connection between the chip suction chamber and the workpiece. During workpiece processing, small chips are generated and are trapped between the elastic membrane and the workpiece, or adhere to the elastic membrane. When the inner and outer clamping blocks are opened directly after processing, these small chips will fall onto the worktable. By adding a movable sleeve, elastic membrane, chip shaking mechanism, and first drive cylinder, after processing is completed, the movable sleeve is moved away from the workpiece. The chip shaking mechanism knocks off the small iron chips on the elastic membrane, which are then collected by the chip suction device. The drilling device is driven by the second drive cylinder, and the stability of the drilling device during movement is improved by the stabilizing mechanism.

[0025] Furthermore, the stabilizing mechanism includes:

[0026] A folding assembly, wherein several folding assemblies are evenly distributed around the axis of the drilling device, and the folding assembly includes a folding rod and a hinge seat;

[0027] Connectors are used to install and connect with all folding components;

[0028] The damper is installed between the connector and the hinge seat;

[0029] A buffer spring is fitted onto the outside of the damper;

[0030] The connector has a first through hole in the middle, through which the output shaft of the second drive cylinder passes.

[0031] The folding assembly is positioned between the drilling device and the movable sleeve. The folding rod is hinged to the hinge seat. When the second drive cylinder drives the drilling device to move towards the workpiece, the folding assembly opens. When the drilling device moves away from the workpiece, the folding assembly folds. There are three or more folding assemblies. The folding rod is hinged to the drilling device and the movable sleeve, so that when the folding assembly moves, it can only control the parallel movement of the drilling device, ensuring the stability of the drill bit when it moves along its axis. The stability of the drilling device during movement is further improved by the connecting parts, dampers, and buffer springs, which improve the drilling accuracy. The first through hole prevents interference between the connecting parts and the output shaft of the second drive cylinder.

[0032] Furthermore, the dust-removing mechanism includes:

[0033] A pull rod, comprising a rod body, a connecting part, and a contact part;

[0034] Pull the seat;

[0035] Locking mechanism, including locking elements;

[0036] Connecting seat, which connects to the pull seat;

[0037] The connecting part is connected to the elastic membrane, the movable sleeve is provided with a movable groove adapted to the pull seat, a sealing partition is provided between the movable groove and the inflation chamber, a first sealing ring is provided between the sealing partition and the pull rod, the hinge seat is provided with a second through hole, the connecting seat is provided with a movable part, and the movable part is movably connected to the second through hole.

[0038] The movable part is movably connected to the second through hole of the hinge seat. The hinge seat and the pull seat are connected through the connecting seat. When the drilling device moves towards the workpiece for processing, the hinge seat moves towards the workpiece, and at the same time, the pull seat and the locking part move towards the workpiece, so that the locking part moves through the abutment part. The rod body, the connecting part and the abutment part are integrally connected. When the drilling device moves back, the locking part abuts against the abutment part, and then the pull rod moves. The connecting part is bonded to the elastic membrane. When the pull rod is pulled, the elastic membrane moves into the inflation chamber. When the locking mechanism releases the pull rod, the elastic membrane is ejected outward under the action of its own elasticity and the air pressure of the inflation chamber, and the small iron filings adhering to the elastic membrane are knocked off. The gas leakage in the inflation chamber is prevented by the sealing partition and the first sealing ring.

[0039] As the first embodiment of the above solution, the locking mechanism further includes:

[0040] Activity seats;

[0041] The first slide is placed on the pull seat, and one end of the first slide is provided with an arc segment;

[0042] The sliding part is placed on the locking member and is adapted to the first sliding groove;

[0043] The third drive cylinder is located between the pull seat and the movable seat;

[0044] The locking member is hinged to the movable seat, and the movable seat is movably connected to the pull seat through the first slide groove.

[0045] The movable seat is adapted to the first slide groove. The locking member is hinged to one side of the movable seat and close to the arc segment. The locking member can move along the first slide groove by adapting to the sliding part. The movable seat is driven to move by the third drive cylinder. The movable seat moves towards the arc segment. When the sliding part moves on the arc segment, the locking member rotates and releases the abutment relationship between the locking member and the abutment part, so that the pull rod is fully reset and the elastic membrane is fully popped out.

[0046] As a second option of the above solution, the locking mechanism further includes:

[0047] Locking spring;

[0048] The unlocking component is movably mounted on the sleeve, and the unlocking component is equipped with rollers;

[0049] The first tooth is placed on the unlocking component;

[0050] The first gear is adapted to the first tooth section;

[0051] The first motor is mounted on the movable sleeve;

[0052] The first gear is mounted on the output shaft of the first motor.

[0053] A locking spring acts on the locking component, which is hinged to the pull seat. The pull seat has a limit part. The locking spring acts between the locking component and the pull seat. When the pull seat moves towards the workpiece, the locking component abuts against the abutment and rotates. After the pull seat moves past the abutment, the locking component separates from the abutment and resets under the action of the locking spring. When the pull seat returns to its original position, the locking component abuts against the abutment, thus enabling the pull rod to move. After the pull seat resets, the roller abuts against the locking component. The first motor drives the first gear to rotate, thereby controlling the rotation of the unlocking component. The rollers act on the locking component one by one, making the locking component contact the abutment. The locking spring is a tension spring. The unlocking component and the movable sleeve are connected by a bearing, allowing the unlocking component to rotate around the axis of the movable sleeve.

[0054] Furthermore, the driving device includes:

[0055] The drive seat is provided with a second slide groove and a third slide groove;

[0056] The fourth slide is placed on the machining table;

[0057] The fifth slide is placed on the machining table;

[0058] The drive motor is installed between the processing table and the drive base;

[0059] The second and fourth slides are adapted to the inner clamping block, and the third and fifth slides are adapted to the outer clamping block.

[0060] The drive motor drives the drive seat to rotate, enabling the inner clamping block to move along the second and fourth slides, and the outer clamping block to move along the third and fifth slides. This allows the inner and outer clamping blocks to move simultaneously, achieving the clamping or releasing of the workpiece.

[0061] This application also provides a manufacturing process for a bicycle rim production device, the specific processing steps of which include:

[0062] S1, place the workpiece on the processing table, drive the drive seat to rotate by the drive motor, thereby driving the outer clamping block and the inner clamping block on the clamping device to move closer to each other to clamp the workpiece. The inner clamping block and the outer clamping block: drive the movable sleeve to move by the first drive cylinder so that the elastic membrane abuts against the workpiece.

[0063] S2, Start the chip suction device, inner clamping block: Start the drilling device, drive the drilling device to move through the second drive cylinder, so that the drill bit acts on the workpiece for processing. When the second drive cylinder moves the drilling device, the connecting part moves at the same time, so that the pull seat moves through the abutment part.

[0064] S3, after the drill bit completes processing, the inner clamping block: the first drive cylinder drives the movable sleeve to move away from the workpiece, the second drive cylinder drives the drilling device to reset, so that the locking part on the locking mechanism abuts against the abutting part, and pulls the pull rod to move, so that the elastic membrane contracts inward. When the drilling device completes the reset, the drilling device is closed, and the abutting relationship between the locking part and the abutting part is released through the locking mechanism, and the elastic membrane pops outward.

[0065] S4, after the drilling device has completed its reset, the outer clamping block: starts the drilling device and drives the drilling device to move through the second drive cylinder, so that the brush head acts on the through hole position that has been machined on the workpiece. When the second drive cylinder moves the drilling device, the connecting piece moves at the same time, so that the pull seat moves through the abutment part.

[0066] S5, after the brush head is processed, the outer clamping block: the first drive cylinder drives the movable sleeve to move away from the workpiece, the second drive cylinder drives the drilling device to reset, so that the locking part on the locking mechanism abuts against the abutting part, and pulls the pull rod to move, so that the elastic membrane contracts inward. When the drilling device is reset, the drilling device is closed, and the abutting relationship between the locking part and the abutting part is released through the locking mechanism, and the elastic membrane pops outward.

[0067] S6. Drive the drive seat to rotate by the drive motor, thereby driving the outer clamping block and the inner clamping block on the clamping device to move away from each other, releasing the workpiece clamping state, removing the finished workpiece, placing the workpiece to be processed, and repeating the above steps.

[0068] Furthermore, the outer clamping block is equipped with a valve body, which is installed on the air inlet channel. The chip suction chamber is equipped with a pressure sensor. The valve body is initially in the open state. When the drilling device in the inner clamping block drills through the workpiece with the drill bit, the valve body is turned into the closed state. The data detected by the pressure sensors on the outer and inner clamping blocks are read. If the pressure values ​​are the same, it indicates that the hole has been drilled through. If the pressure values ​​are different, it indicates that an abnormality has occurred and an alarm is triggered.

[0069] The beneficial effects of this application are:

[0070] 1. Both the inner and outer clamping blocks are equipped with chip suction chambers. The drilling device is installed inside the chip suction chamber. The iron chips generated by drilling through the drilling device fall into the chip suction chamber. Then, the negative pressure device sucks the iron chips in the chip suction chamber and collects them in the chip collection box through the discharge channel, ensuring the cleanliness of the workbench and reducing the labor intensity of the workers in cleaning the workbench.

[0071] 2. The fixed sealing ring is placed around the periphery of the chip suction chamber. The fixed sealing ring abuts against the workpiece, which increases the sealing performance between the inner clamping block, the outer clamping block and the workpiece, and prevents iron chips, dust and other materials from being discharged from the gap between the clamping block and the workpiece. Air is allowed to enter the chip suction chamber through the air inlet channel, which facilitates the flow of gas to transport the iron chips in the chip suction chamber to the chip collection box.

[0072] 3. The movable sleeve is driven by the first drive cylinder. When the movable sleeve moves towards the workpiece, the elastic membrane comes into contact with the workpiece, improving the tightness of the connection between the chip suction chamber and the workpiece. During the processing of the workpiece, small chips are generated and are trapped between the elastic membrane and the workpiece, or adhere to the elastic membrane. When the inner and outer clamping blocks are opened directly after processing, these small chips will fall onto the worktable. After processing is completed, the movable sleeve, elastic membrane, chip shaking mechanism and first drive cylinder move the movable sleeve away from the workpiece. The chip shaking mechanism knocks the small iron chips off the elastic membrane and then collects them under the action of the chip suction device.

[0073] 4. When the folding assembly is in motion, it can only control the parallel movement of the drilling device to ensure the stability of the drill bit when it moves along its axis. The stability of the drilling device during movement is further improved by the connecting parts, dampers, and buffer springs, thereby improving the drilling accuracy. Attached Figure Description

[0095] The clamping device 300 moves in the same direction as the radial direction of the iron ring. The clamping device 300 is provided with a chip suction chamber 301, which is placed on the inner clamping block 310 and the outer clamping block 320. The drilling device 200 is placed in the chip suction chamber 301 of the inner clamping block 310. The clamping device 300 is provided with a chip discharge channel 302, which is connected between the chip suction device 400 and the chip suction chamber 301.

[0096] The workpiece is clamped by the clamping device 300. The inner clamping block 310 and the outer clamping block 320 are both adapted to the workpiece. The driving device 500 is used to drive the inner clamping block 310 and the outer clamping block 320 to move. Both the inner clamping block 310 and the outer clamping block 320 are provided with chip suction chambers 301. The drilling device 200 is installed in the chip suction chamber 301. The iron chips generated by drilling by the drilling device 200 fall into the chip suction chamber 301. Then, the negative pressure device 410 sucks the iron chips in the chip suction chamber 301 and collects them in the chip collection box through the discharge channel. In section 420, to ensure the cleanliness of the workbench and reduce the labor intensity of workers cleaning the workbench, both the inner clamping block 310 and the outer clamping block 320 are equipped with drilling devices 200. The drilling devices 200 on the inner clamping block 310 are used to drill holes for machining through holes in the workpiece, and the drilling devices 200 on the outer clamping block 320 are equipped with brush heads 220 for removing burrs from the edges of the through holes. The driving device 500 clamps all the inner clamping blocks 310 and the outer clamping blocks 320 simultaneously, increasing the clamping speed and improving the processing efficiency of the workpiece.

[0097] Example 2:

[0107] The movable sleeve 340 is provided with an inflation chamber 342, and the elastic membrane 341 is installed at the opening of the inflation chamber 342.

[0108] A fixed sealing ring 330 is placed around the periphery of the chip suction chamber 301. By abutting against the workpiece, the fixed sealing ring 330 increases the sealing performance between the inner clamping block 310, the outer clamping block 320, and the workpiece, preventing iron filings and dust from escaping through the gap between the clamping blocks and the workpiece. Air is introduced into the chip suction chamber 301 through the air inlet channel 350, facilitating gas flow and transporting the iron filings in the chip suction chamber 301 to the chip collection box 420. The negative pressure in the chip suction chamber 301 and the structure of the fixed sealing ring 330 enhance the clamping effect between the inner and outer clamping blocks 320 and the workpiece, improving the stability of the workpiece during processing. A movable sleeve 340 is movably installed in the chip suction chamber 301. The movable sleeve 340 is driven to move by the first drive cylinder 360. An elastic diaphragm 341 is installed on the movable sleeve 340. Air is filled in the inflation chamber 342, causing the elastic diaphragm 341 to bulge outwards. When the movable sleeve 340 moves towards the workpiece, the elastic membrane 341 comes into contact with the workpiece, improving the tightness of the connection between the chip suction chamber 301 and the workpiece. During workpiece processing, small chips are generated and are trapped between the elastic membrane 341 and the workpiece, or adhere to the elastic membrane 341. When the inner and outer clamping blocks 320 are opened directly after processing, these small chips will fall onto the worktable. By adding the movable sleeve 340, elastic membrane 341, chip shaking mechanism 600, and first drive cylinder 360, after processing is completed, the movable sleeve 340 is moved away from the workpiece, and the chip shaking mechanism 600 knocks off the small iron chips on the elastic membrane 341. Then, they are collected by the chip suction device 400. The drilling device 200 is driven by the second drive cylinder 370, and the stability of the drilling device 200 during movement is improved by the stabilizing mechanism 700.

[0110] Example 3:

[0111] like Figure 5 As shown, this application embodiment provides a bicycle rim production apparatus, which, in addition to including the above-mentioned technical features, further includes the stabilizing mechanism 700 comprising:

[0112] Folding assembly 710, a plurality of folding assemblies 710 are evenly distributed around the axis of drilling device 200, the folding assembly 710 includes folding rod 711 and hinge seat 712;

[0116] The connector 720 has a first through hole 721 in the middle, and the output shaft of the second drive cylinder 370 passes through the first through hole 721.

[0117] The folding assembly 710 is positioned between the drilling device 200 and the movable sleeve 340. The folding rod 711 is hinged to the hinge seat 712. When the second drive cylinder 370 drives the drilling device 200 to move towards the workpiece, the folding assembly 710 opens. When the drilling device 200 moves away from the workpiece, the folding assembly 710 folds. The folding assembly 710 is provided with three or more sets. The folding rod 711 is hinged to the drilling device 200 and the movable sleeve 340, so that when the folding assembly 710 moves, it can only control the drilling device 200 to move in parallel, ensuring the stability of the drill bit 210 when it moves along its axis. The stability of the drilling device 200 when it moves is further improved by the connecting piece 720, the damper 730, and the buffer spring 740, thereby improving the drilling accuracy. The first through hole 721 prevents interference between the connecting piece 720 and the output shaft of the second drive cylinder 370.

The hinge seat 712 is provided with a second through hole 713. The connecting seat 640 is provided with a movable part 641, and the movable part 641 is movably connected to the second through hole 713.

[0125] The movable part 641 is movably connected to the second through hole 713 of the hinge seat 712. The hinge seat 712 is connected to the pull seat 620 via the connecting seat 640. When the drilling device 200 moves towards the workpiece for machining, the hinge seat 712 moves towards the workpiece, simultaneously causing the pull seat 620 and the locking member 631 to move towards the workpiece. This allows the locking member 631 to move through the abutment part 613. The rod body 611, the connecting part 612, and the abutment part 613 are integrally connected. When the drilling device 200 moves back... The locking member 631 abuts against the abutment part 613, and then the pull rod 610 is pulled to move. The connecting part 612 is bonded to the elastic membrane 341. When the pull rod 610 is pulled, the elastic membrane 341 moves into the inflation chamber 342. When the locking mechanism 630 releases the pull rod 610, the elastic membrane 341 is ejected outward under the action of its own elasticity and the air pressure of the inflation chamber 342, and the small iron filings adhering to the elastic membrane 341 are knocked off. The gas leakage in the inflation chamber 342 is prevented by the sealing partition 344 and the first sealing ring 345.

[0126] Example 5:

[0127] like Figure 7 As shown, this application embodiment provides a bicycle rim production apparatus. As the first embodiment of the above solution, the locking mechanism 630 further includes:

[0128] Activity seat 651;

[0129] The first slide groove 652 is placed on the pull seat 620, and one end of the first slide groove 652 is provided with an arc segment 653;

[0130] The sliding part 654 is placed on the locking member 631 and is adapted to the first sliding groove 652;

[0131] The third drive cylinder 655 is located between the pull seat 620 and the movable seat 651;

[0132] The locking member 631 is hinged to the movable seat 651, and the movable seat 651 is movably connected to the pull seat 620 through the first sliding groove 652.

[0133] The movable seat 651 is adapted to the first slide groove 652. The locking member 631 is hinged to one side of the movable seat 651 and close to the arc segment 653. The sliding part 654 is adapted to the first slide groove 652, so that the locking member 631 can move along the first slide groove 652. The movable seat 651 is driven to move by the third drive cylinder 655. The movable seat 651 moves towards the arc segment 653. When the sliding part 654 moves on the arc segment 653, the locking member 631 rotates and releases the abutment relationship between the locking member 631 and the abutment part 613, so that the pull rod 610 is fully reset and the elastic membrane 341 is fully ejected.

[0134] Each lever 610 can abut against the locking element 631. The pull seat 620 and the movable seat 651 are in a ring shape, and all locking elements 631 are hinged to the movable seat 651.

[0135] Example 6:

[0136] like Figure 8 As shown, this application embodiment provides a bicycle rim production apparatus. In addition to the aforementioned technical features, as a second embodiment of the above solution, the locking mechanism 630 further includes:

[0137] Locking spring 660;

[0138] The unlocking component 661 is movably installed on the movable sleeve 340, and the unlocking component 661 is provided with a roller 662;

[0139] The first tooth 663 is placed on the unlocking member 661;

[0140] The first gear 664 is adapted to the first tooth 663;

[0141] The first motor 665 is mounted on the movable sleeve 340;

[0142] The first gear 664 is mounted on the output shaft of the first motor 665.

[0143] A locking spring 660 acts on the locking member 631, which is hinged to the pull seat 620. The pull seat 620 has a limiting part. The locking spring 660 acts between the locking member 631 and the pull seat 620. When the pull seat 620 moves towards the workpiece, the locking member 631 abuts against the abutment part 613 and rotates. After the pull seat 620 moves past the abutment part 613, the locking member 631 separates from the abutment part 613 and resets under the action of the locking spring 660. When the pull seat 620 returns to its original position, the locking member 631... The abutting part 613 abuts against each other, thereby enabling the pull rod 610 to move. After the pull seat 620 completes its reset, the roller 662 abuts against the locking member 631. The first motor 665 drives the first gear 664 to rotate, thereby controlling the rotation of the unlocking member 661. The rollers 662 act on the locking member 631 one by one, so that the locking member 631 and the abutting part 613 come into contact and abut against each other. The locking spring 660 is a tension spring. The unlocking member 661 and the movable sleeve 340 are connected by a bearing, so that the unlocking member 661 can rotate around the axis of the movable sleeve 340.

[0144] This embodiment is a parallel solution to the previous embodiment. The previous embodiment can pop out the elastic membrane 341 at the same time, but the disadvantage is that it requires multiple third drive cylinders 655. In this embodiment, each locking member 631 is independent of each other and can pop out the elastic membrane 341 slowly. In terms of effect, the simultaneous popping out of the elastic membrane 341 has a better dust-removing effect.

[0145] like Figure 9 As shown, another solution is proposed based on the first two embodiments. The locking mechanism 630 further includes: a locking spring 660; and an unlocking member 661. The unlocking member 661 is provided with a protrusion 671. The installation relationship between the locking spring 660, the locking member 631, and the pull seat 620 is the same as in this embodiment. The protrusion 671 is installed in a ring on the unlocking member 661. When the pull seat 620 is reset, the protrusion 671 acts on all the unlocking members 661, causing all the pull rods 610 to reset. At the same time, all the elastic membranes 341 pop out. This solution does not require additional power drive, is more convenient and faster, and the chip removal effect remains unchanged.

[0146] Example 7:

[0147] like Figure 10 As shown, this application embodiment provides a bicycle rim production apparatus, which, in addition to including the above-mentioned technical features, further includes a drive device 500 comprising:

[0148] The drive base 520 is provided with a second slide groove 521 and a third slide groove 522;

[0149] The fourth slide 110 is placed on the processing table 100;

[0150] The fifth slide 120 is placed on the processing table 100;

[0151] The drive motor 510 is installed between the processing table 100 and the drive base 520;

[0152] The second slide groove 521 and the fourth slide groove 110 are adapted to the inner clamping block 310, and the third slide groove 522 and the fifth slide groove 120 are adapted to the outer clamping block 320.

[0153] The drive motor 510 drives the drive base 520 to rotate, so that the inner clamping block 310 can move along the second slide groove 521 and the fourth slide groove 110, and the outer clamping block 320 can move along the third slide groove 522 and the fifth slide groove 120, thereby controlling the inner and outer clamping blocks 320 to move simultaneously, so as to clamp or release the workpiece.

[0154] Example 8:

[0155] This application also provides a manufacturing process for a bicycle rim production device, the specific processing steps of which include:

[0156] S1, the workpiece is placed on the processing table 100, and the drive seat 520 is driven to rotate by the drive motor 510, thereby driving the outer clamping block 320 and the inner clamping block 310 on the clamping device 300 to come closer to each other to clamp the workpiece. The inner clamping block 310 and the outer clamping block 320: the movable sleeve 340 is moved by the first drive cylinder 360 so that the elastic membrane 341 abuts against the workpiece.

[0157] S2, Start the chip suction device 400, inner clamping block 310: Start the drilling device 200, drive the drilling device 200 to move through the second drive cylinder 370, so that the drill bit 210 acts on the workpiece for processing. When the second drive cylinder 370 moves the drilling device 200, the connecting piece 720 moves at the same time, so that the pull seat 620 moves through the abutment part 613.

[0158] S3, after the drill bit 210 completes processing, the inner clamping block 310: the first drive cylinder 360 drives the movable sleeve 340 to move away from the workpiece, the second drive cylinder 370 drives the drilling device 200 to reset, so that the locking part 631 on the locking mechanism 630 abuts against the abutment part 613, and pulls the pull rod 610 to move, so that the elastic membrane 341 contracts inward. When the drilling device 200 completes the reset, the drilling device 200 is closed, and the abutment relationship between the locking part 631 and the abutment part 613 is released through the locking mechanism 630, and the elastic membrane 341 pops outward.

[0159] S4, after the drilling device 200 has completed its reset, the outer clamping block 320: starts the drilling device 200 and drives the drilling device 200 to move through the second drive cylinder 370, so that the brush head 220 acts on the through hole position that has been machined on the workpiece. When the second drive cylinder 370 moves the drilling device 200, the connecting piece 720 moves at the same time, so that the pull seat 620 moves through the abutment part 613.

[0160] S5, after the brush head 220 has completed processing, the outer clamping block 320: the first drive cylinder 360 drives the movable sleeve 340 to move away from the workpiece, the second drive cylinder 370 drives the drilling device 200 to reset, so that the locking part 631 on the locking mechanism 630 abuts against the abutment part 613, and pulls the pull rod 610 to move, so that the elastic membrane 341 contracts inward. When the drilling device 200 has completed reset, the drilling device 200 is closed, and the abutment relationship between the locking part 631 and the abutment part 613 is released through the locking mechanism 630, and the elastic membrane 341 pops outward.

[0161] S6, the drive motor 510 drives the drive seat 520 to rotate, thereby driving the outer clamping block 320 and the inner clamping block 310 on the clamping device 300 to move away from each other, releasing the workpiece clamping state, removing the finished workpiece, placing the workpiece to be processed, and repeating the above steps.

[0162] Furthermore, the outer clamping block 320 is provided with a valve body 303, which is installed on the air inlet channel 350. The chip suction chamber 301 is provided with a pressure sensor. The valve body 303 is initially in the open state. When the drilling device 200 in the inner clamping block 310 drills through the workpiece with the drill bit 210, the valve body 303 is turned into the closed state. The data detected by the pressure sensors on the outer clamping block 320 and the inner clamping block 310 are read. If the pressure values ​​are the same, it means that the hole has been drilled through. If the pressure values ​​are different, it means that an abnormality has occurred and an alarm is triggered.

[0163] When the drilling device 200 is drilling or deburring, the chip suction device 400 is turned on to suck the iron chips into the chip collection box 420. Before the drilling device 200 is processing, the fixing sealing ring 330 and the elastic membrane 341 are pressed against the workpiece. A small amount of small iron chips are in contact with the elastic membrane 341 and cannot be sucked by the chip suction device 400. When the drilling device 200 on the inner and outer clamping blocks 320 is finished processing, the contact between the elastic membrane 341 and the workpiece is made. The chip shaking mechanism 600 knocks the small iron chips off the elastic membrane 341, so that when the inner and outer clamping blocks 320 are opened, the iron chips fall onto the processing table 100.

[0164] By installing a valve body 303 on the air inlet channel 350 on the outer clamping block 320, after the drilling device 200 completes the drilling, the air pressure in the chip suction chamber 301 inside the inner and outer clamping blocks 320 is detected to determine whether the drilling on the workpiece is completed. If an unexpected failure occurs, an alarm is triggered.
