Description

Technical Field

[0001] This application relates to the field of pin pressing, and in particular to an automatic pin pressing device. Background Technology

[0002] In the field of automated machining and assembly technology, using locating pins pressed into sheet metal as assembly references is a core process for achieving high-precision alignment and reliable fastening of components. Taking common bakelite boards as an example, when used as substrates for electronic components, the pins pre-pressed into the holes provide a unique physical positioning reference for the subsequent installation of components, thus ensuring the consistency and interchangeability of mass-produced products. In precision mold insert assembly scenarios, the pins undertake the function of high-precision positioning and connection between templates. Therefore, high-quality drilling and pin pressing into the sheet metal directly determines the assembly accuracy and structural stability of the final product.

[0003] In existing technologies, there are two main methods for drilling and pinning sheet metal. The first is purely manual, where operators use a hand drill or bench drill to drill pre-defined holes in the sheet metal, then manually select the corresponding pins and hammer them into the holes using a hammer or simple press. This method is low-cost and highly flexible. The second method combines a CNC drilling center with a pinning machine. The CNC drilling center precisely processes all the holes according to a program, and then the entire sheet metal is manually transferred to a semi-automatic pinning machine to press the pins in.

[0004] Regarding the aforementioned technologies, drilling and press-fitting are completed at multiple workstations, either manually or by two separate pieces of equipment in stages. This results in the sheet metal having to be transferred multiple times between different workstations, making the entire process lack continuity and affecting production efficiency. Application content

[0005] To improve the production continuity of pin pressing, this application provides an automatic pin pressing device.

[0006] The automatic pin pressing device provided in this application adopts the following technical solution: An automatic pin pressing device includes a frame, an X-axis drive, a Y-axis drive, a Z-axis drive, and a pressing head; The equipment frame is horizontally slidable along the Y-axis and is fitted with a machining slide. The machining slide is equipped with a pin holder, a tool holder and a tool measuring device. The Y-axis drive is used to move the machining slide along the Y-axis. The X-axis drive is used to make the pressing head move horizontally along the X-axis direction, and the Z-axis drive is used to make the pressing head move vertically along the Z-axis direction. The press head includes a head base plate, pin clamps, and a drilling spindle. The pin clamps and the drilling spindle are both mounted on the head base plate and are distributed along the X-axis.

[0007] By adopting the above technical solution, the drilling spindle and pin clamps are both mounted on the machine head base plate and distributed along the X-axis. The X-axis drive, Y-axis drive, and Z-axis drive respectively drive the press head and the processing slide to move in the three-axis direction. This allows the equipment to use the tool holder and pin holder mounted on the processing slide to provide tools and pins respectively. The tool or pin is detected by a tool tester. Then, the same press head performs drilling and pin pressing operations sequentially in the same equipment. This helps to reduce the transfer caused by multi-station operations and improves the continuity and production efficiency of the drilling and pressing process.

[0008] Optionally, a plurality of pin holders, tool holders, tool measuring devices, pin clamps, and drilling spindles are provided, and the pin holders, tool holders, tool measuring devices, pin clamps, and drilling spindles are at least in one-to-one correspondence.

[0009] By adopting the above technical solutions, it is easy to quickly switch between pins and cutting tools of different specifications, or to perform multiple sets of drilling and pressing operations in parallel, thereby improving the production flexibility and processing efficiency of the equipment.

[0010] Optionally, the Z-axis drive component includes a Z-axis lead screw and a Z-axis motor. The Z-axis lead screw is arranged vertically along the Z-axis and is threaded into the machine head base plate. The Z-axis motor is used to rotate the Z-axis lead screw, and the machine head base plate can slide vertically along the Z-axis direction.

[0011] By adopting the above technical solution, the Z-axis drive component can convert the rotational motion of the motor into the linear lifting motion of the machine head base plate, which helps to improve the motion accuracy and running stability of the press head in the Z-axis direction, thereby reducing the occurrence of drilling depth deviation and pin pressing failure, and improving the processing quality of the product.

[0012] Optionally, the pin clamping claw slides vertically along the Z-axis and engages with the machine head base plate. The machine head base plate is equipped with a pressing cylinder, which is vertically arranged along the Z-axis, and the output shaft of the pressing cylinder is installed on the pin clamping claw.

[0013] By adopting the above technical solution, the pressing action of the pin clamping claw is independent of the overall lifting and lowering movement of the pressing head. This allows for precise control of the pin pressing stroke and pressing force through the pressing cylinder, thereby reducing the occurrence of pin pressing depth deviation and incomplete pressing, and improving the consistency and reliability of pin pressing.

[0014] Optionally, the machine head base plate is equipped with a negative pressure cleaning ring and a cleaning ring drive. The negative pressure cleaning ring is sleeved on the bottom of the drilling spindle, and the cleaning ring drive is used to make the negative pressure cleaning ring move vertically along the Z-axis.

[0015] By adopting the above technical solution, the cleaning ring drive can drive the negative pressure cleaning ring to move vertically along the Z-axis, thereby adjusting the height of the negative pressure cleaning ring according to the thickness of the processed plate. The negative pressure cleaning ring generates negative pressure during drilling to adsorb dust and debris, which helps to reduce the scattering and accumulation of drilling dust, improve the cleanliness of the processing environment, and reduce the impact of dust adhesion on the subsequent pin pressing accuracy.

[0016] Optionally, the bottom of the negative pressure cleaning ring is equipped with barrier bristles, which surround the drilling spindle.

[0017] By adopting the above technical solution, the negative pressure cleaning ring can form a flexible physical barrier with the help of the bristles during drilling operations, which helps to reduce the occurrence of drilling dust and debris flying outward and better confine the dust in the negative pressure adsorption area, thereby improving the dust removal effect of the negative pressure cleaning ring.

[0018] Optionally, the equipment frame is provided with a tool holder slide groove, and both the pin tool holder and the cutting tool holder slide horizontally along the X-axis direction and are engaged with the tool holder slide groove.

[0019] By adopting the above technical solution, the pin holder and the tool holder can be easily installed and removed along the slide, which makes it easier for users to quickly replenish the pins or replace the worn tool holder, thereby reducing the downtime caused by tool holder replacement and improving the continuity of production operations and the convenience of maintenance.

[0020] Optionally, the equipment frame is equipped with a transfer tool holder, which has a first tool insertion hole and a second tool insertion hole. The first tool insertion hole and the second tool insertion hole are horizontally distributed along the X-axis direction. The first tool insertion hole extends vertically along the Z-axis direction and is used to place the tool to be taken by the drilling spindle. The second tool insertion hole extends vertically along the Z-axis direction and is used to place the tool to be returned to the tool holder. The tool measuring device is mounted on the equipment frame through the transfer tool holder.

[0021] By adopting the above technical solution, the drilling spindle can directly retrieve the tool to be used from the first tool holder and temporarily store the used tool in the second tool holder for return to the tool holder. This allows the tool retrieval and return actions to be carried out in an orderly and coordinated manner within the same area, thereby simplifying the movement path of the press head and improving tool changing efficiency and machining continuity. Simultaneously, the tool measuring device is mounted on the equipment frame via a transfer tool holder, concentrating the tool retrieval and inspection areas. This facilitates timely dimensional inspection before tool retrieval, reducing machining defects caused by tool flaws.

[0022] Optionally, the Y-axis drive is a linear motor, the Y-axis drive is mounted on the equipment frame, and the machining slide is mounted on the mover of the Y-axis drive.

[0023] By adopting the above technical solution, the linear motor drives the machining slide to move linearly, which helps to improve the motion accuracy and running stability of the machining slide in the Y-axis direction, reduce the occurrence of inaccurate positioning due to transmission backlash or drive deviation, and improve the positioning accuracy of drilling and pin pressing.

[0024] Optionally, the X-axis drive is a linear motor, the X-axis drive is mounted on the equipment frame, and the press head is mounted on the mover of the X-axis drive.

[0025] By adopting the above technical solution, the linear motor drives the press head to move linearly, enabling the press head to move smoothly along the X-axis direction. This helps to reduce the positional deviation of the press head when positioning in the X-axis direction, thereby reducing the occurrence of drilling and pin pressing position offsets, improving processing consistency and equipment operation stability.

[0026] In summary, this application includes at least one of the following beneficial technical effects: The drilling spindle and pin clamps are mounted on the base plate of the machine head and distributed along the X-axis. They are driven by the X-axis drive, Y-axis drive and Z-axis drive to move the press head and the processing slide in three directions. This allows the equipment to use the tool holder and pin holder mounted on the processing slide to provide tools and pins respectively. The tool or pin is detected by the tool tester. Drilling and pin pressing operations are performed sequentially by the same press head in the same equipment. This helps to reduce the transfer caused by multi-station operation and improve the continuity and production efficiency of the drilling and pressing process. The cleaning ring drive can drive the negative pressure cleaning ring to move vertically along the Z-axis, thereby adjusting the height of the negative pressure cleaning ring according to the thickness of the processed material. The negative pressure cleaning ring generates negative pressure during drilling to adsorb dust and debris, which helps to reduce the scattering and accumulation of drilling dust, improve the cleanliness of the processing environment, and reduce the impact of dust adhesion on the subsequent pin pressing accuracy. The pin holder and the tool holder can be easily installed and removed along the slide, which makes it easy for users to quickly replenish the pins or replace the worn tool holder. This helps to reduce downtime caused by tool holder replacement and improve the continuity of production and the convenience of maintenance. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0036] Example 1: This application discloses an automatic pin pressing device. (Refer to...) Figure 1 The automatic pin pressing equipment includes a frame 1, an X-axis drive unit, a Y-axis drive unit, a Z-axis drive unit, and a pressing head 5. The frame 1 serves as a load-bearing foundation, used to support and install other functional components.

[0037] The equipment frame 1 is equipped with a machining slide 11 that slides horizontally along the Y-axis via four slide rails. The machining slide 11 can reciprocate along the Y-axis under the action of the Y-axis drive component. The Y-axis drive component includes a Y-axis lead screw 31 and a Y-axis motor (not shown in the figure). The Y-axis lead screw 31 is horizontally arranged along the Y-axis and is threaded into the machining slide 11. The Y-axis motor is fixedly installed on the equipment frame 1 and rotates the Y-axis lead screw 31 through direct drive or mechanical transmission, thereby converting the rotational motion of the Y-axis lead screw 31 into the linear motion of the machining slide 11, improving the motion accuracy and running stability of the machining slide 11 in the Y-axis direction.

[0038] Reference Figure 1 and Figure 2 The machining slide 11 is equipped with two sets of pin holders 111 and tool holders 112, with one set of pin holders 111 corresponding to another. The top of the pin holder 111 has several slots for fitting pins, facilitating the storage of pins to be pressed in. The top of the tool holder 112 also has several slots for fitting tools, facilitating the storage of drilling tools. The machine frame 1 has two tool holder grooves 101 extending along the X-axis and facing each other. Both the pin holders 111 and tool holders 112 slide horizontally along the X-axis and engage with the tool holder grooves 101 via protrusions on both sides. This allows the user to quickly push a full tool holder or slide an empty tool holder horizontally through the protrusions and grooves, facilitating rapid replacement of pins and tools.

[0039] The equipment frame 1 is also fixedly equipped with two intermediate tool holders 12, which correspond to a set of pin tool holders 111 and pin tool holders 111, respectively. The intermediate tool holders 12 are used to coordinate the use and return of tools. Specifically, the intermediate tool holders 12 have a first tool insertion hole 121 and a second tool insertion hole 122, which are horizontally distributed along the X-axis. The first tool insertion hole 121 extends vertically along the Z-axis and is used to place the tool to be taken by the drilling spindle 53. The second tool insertion hole 122 extends vertically along the Z-axis and is used to place the tool to be returned to the tool holder 112.

[0040] The equipment frame 1 is fixedly mounted with an existing tool measuring device 13 via a transfer tool holder 12. The tool measuring device 13 is positioned closer to the second tool insertion hole 122 than the first tool insertion hole 121, and is used to promptly detect the dimensions of pins or tools, so as to detect and remove unqualified pins and tools in advance, reducing machining defects caused by pin or tool defects. During operation, the pin clamp 52 grabs the required tool from the tool holder 112 and inserts it into the first tool insertion hole 121, so that the drilling spindle 53 can directly pick up the tool to be used from the first tool insertion hole 121. After the drilling spindle 53 has finished using the tool, it inserts the tool into the second tool insertion hole 122, and the pin clamp 52 grabs it and returns it to the tool holder 112. The tool picking and returning actions are carried out in an orderly and coordinated manner within the same area, which helps to simplify the movement path of the press head 5, improve tool changing efficiency and machining continuity.

[0041] Reference Figure 1 The pressing head 5 is mounted on the pressing head moving base 6. The pressing head moving base 6 slides horizontally along the X-axis direction via two slide rails, allowing the pressing head 5 to move horizontally along the X-axis direction together with the pressing head moving base 6. The X-axis drive components include an X-axis gear (not shown in the figure) and an X-axis motor 21. An X-axis rack 14 is horizontally fixedly mounted on the equipment frame 1 along the X-axis direction, and the X-axis gear meshes with the X-axis rack 14. The X-axis motor 21 is fixedly mounted on the pressing head moving base 6, and the X-axis gear is coaxially fixedly mounted on the output shaft of the X-axis motor 21, so that the X-axis motor 21 drives the X-axis gear to rotate, thereby allowing the pressing head moving base 6 to drive the pressing head 5 to move smoothly along the X-axis direction.

[0042] Reference Figure 3 The press head 5 includes a head base plate 51, pin grippers 52, and a drilling spindle 53. Both the pin grippers 52 and the drilling spindle 53 are provided in two sets, with one set of pin grippers 52 and drilling spindle 53 corresponding to one set of pin holders 111 and tool holders 112. The pin grippers 52 and drilling spindle 53 are both mounted on the head base plate 51, and are distributed along the X-axis to reduce idle travel during operation switching, shorten the operation cycle, and improve production efficiency. The head base plate 51 slides vertically along the Z-axis to engage with the head moving seat 6 via two slide rails, allowing the head base plate 51 to slide vertically along the Z-axis. The Z-axis drive components include a Z-axis lead screw 41 and a Z-axis motor 42. The Z-axis lead screw 41 is vertically arranged along the Z-axis and rotatably engaged with the head moving seat 6, and is threadedly engaged with the head base plate 51. The Z-axis motor 42 is fixedly installed on the top of the machine head moving seat 6, and the Z-axis lead screw 41 is coaxially fixedly installed on the output shaft of the Z-axis motor 42, so that the Z-axis motor 42 can drive the Z-axis lead screw 41 to rotate, thereby causing the entire pressing machine head 5 to move linearly up and down through the machine head base plate 51.

[0043] Reference Figure 3 and Figure 4 The pin gripper 52 is capable of gripping a pin from the pin holder 111 and pressing the gripped pin into the hole in the plate. Specifically, the pin gripper 52 is a conventional pneumatic gripper, which slides vertically along the Z-axis and engages with the machine head base plate 51 via a slide rail. A pressing cylinder 521 is fixedly mounted on the top of the machine head base plate 51. The pressing cylinder 521 is vertically arranged along the Z-axis, and the output shaft of the pressing cylinder 521 is fixedly mounted on the pin gripper 52. After the press head 5 is positioned as a whole by the X-axis drive, Y-axis drive and Z-axis drive, the press cylinder 521 can independently drive the pin clamp 52 to perform vertical press action. This makes the press action of the pin clamp 52 independent of the overall lifting and lowering movement of the press head 5. This makes it easier to accurately control the pressing stroke and pressing force of the pin through the press cylinder 521, reduce the pin pressing depth deviation and incomplete pressing, and improve the consistency and reliability of pin pressing.

[0044] Reference Figure 5 The drilling spindle 53 can be moved to the position of the first tool holder 121 via the X-axis drive, Y-axis drive, and Z-axis drive to pick up the tool from the relatively spacious first tool holder 121 and drill holes in the workpiece. Specifically, the existing electrically driven drilling spindle 53 is vertically fixedly mounted on the machine head base plate 51, and the bottom of the drilling spindle 53 is provided with a tool holder socket (not shown in the figure) adapted to the tool. The drilling spindle 53 moves closer to or away from the workpiece placed on the top of the machining slide 11 by rotating the Z-axis lead screw 41, so as to facilitate drilling holes in the workpiece by rotating the tool.

[0045] Reference Figure 5 and Figure 6The machine head base plate 51 is equipped with a negative pressure cleaning ring 531 and a cleaning ring drive 532. The negative pressure cleaning ring 531, connected to an external negative pressure device (not shown in the figure) via a hose, is fitted onto the bottom of the drilling spindle 53, and slides along the Z-axis direction on the machine head base plate 51 via linear bearings on both sides. The cleaning ring drive 532 is used to move the negative pressure cleaning ring 531 vertically along the Z-axis direction. In this embodiment, the cleaning ring drive 532 is specifically a cylinder. The cleaning ring drive 532 is vertically fixedly installed on the machine head base plate 51, and its output rod is fixedly installed on the top of the negative pressure cleaning ring 531 via a coupling, so that the extension and retraction of the output rod of the cleaning ring drive 532 can drive the negative pressure cleaning ring 531 to move along the Z-axis direction. During drilling operations, the negative pressure cleaning ring 531 uses the negative pressure generated by the hose to adsorb dust and debris, which helps reduce the dispersion and accumulation of drilling dust, improves the cleanliness of the processing environment, and reduces the impact of dust adhesion on the subsequent pin pressing accuracy. In addition, a ring of barrier bristles 533 is fixedly installed at the bottom of the negative pressure cleaning ring 531, surrounding the drilling spindle 53. When the negative pressure cleaning ring 531 descends to close to the surface of the workpiece, the barrier bristles 533 form a flexible physical barrier, reducing the outward dispersion of drilling dust and debris and better confining the dust within the negative pressure adsorption area, thereby ensuring the dust removal effect of the negative pressure cleaning ring 531.

[0046] The implementation principle of the automatic pin pressing equipment in Embodiment 1 of this application is as follows: Step S1: Under the drive of the Y-axis drive, the machining slide 11 moves the tool holder 112 to the tool-grabbing position of the pin clamp 52. The X-axis and Z-axis drives drive the pin clamp 52 to move directly above the tool holder 112. The Z-axis drive moves the pin clamp 52 downward to grab the tool. Subsequently, the press head 5 moves under the action of the X-axis and Z-axis drives, aligning the pin clamp 52 with the first tool insertion hole 121 of the transfer tool holder 12 fixed to the machine frame 1. The pin clamp 52 moves downward to smoothly place the tool into the first tool insertion hole 121.

[0047] Step S2: The press head 5 moves under the action of the X-axis drive and the Z-axis drive, so that the drilling spindle 53 is aligned with the first tool insertion hole 121, and the drilling spindle 53 moves downward to pick up the tool. Then the drilling spindle 53 moves to the tool measuring device 13 fixed on the intermediate tool holder 12 to check the size of the tool, and the tool measuring device 13 feeds back data to determine whether the tool is qualified.

[0048] Step S3: After passing the inspection, the drilling spindle 53, carrying the cutting tool, is positioned under the control of the X-axis and Z-axis drives. The machining slide 11, driven by the Y-axis drive, moves the workpiece and, in conjunction with the drilling spindle 53, performs continuous drilling according to a preset program. During drilling, the cleaning ring drive 532 causes the bristles 533 to adhere to the surface of the workpiece, and, in conjunction with the negative pressure cleaning ring 531, adsorbs drilling dust.

[0049] Step S4: After all drilling is completed, the press head 5 moves to align the drilling spindle 53 with the second tool insertion hole 122 of the central tool holder 12. The drilling spindle 53 moves downward to insert the tool into the second tool insertion hole 122. Then, the pin chuck 52 moves above the second tool insertion hole 122 and moves downward to pick up the tool. The machining slide 11 moves the tool holder 112 below the pin chuck 52, and the pin chuck 52 puts the tool back into the tool holder 112, completing the tool return process.

[0050] Step S5: After drilling and tool changing, the machining slide 11 moves the pin holder 111 to the pin chuck 52's pick-up station. The pin chuck 52 moves above the pin holder 111 under the drive of the X and Z axes to pick up the pin. Then, it moves the pin-carrying device 13 above the tool measuring device for dimensional inspection.

[0051] Step S6: After passing the inspection, the machining slide 11 moves the pre-drilled hole position of the plate to below the pin clamp 52. The pressing cylinder 521 independently drives the pin clamp 52 to move down along the Z-axis, accurately pressing the pin into the hole drilled by the drilling spindle 53.

[0052] Step S7: Repeat steps S5 and S6 until all holes in the board are pressed into the pins. After replacing with the next board, repeat steps S1 to S7.

[0053] In summary, by integrating the drilling spindle 53 and the pin clamp 52 onto the same machine head base plate 51, and coordinating with the X-axis drive, Y-axis drive and Z-axis drive to drive the press head 5 and the processing slide 11 to move in the three-axis directions, the equipment can perform drilling, pin pressing and pin tool inspection operations within the same machine using the same press head 5. This helps to improve the production continuity of pin pressing and reduce material transfer caused by multi-station operations.

[0054] Example 2: This application discloses an automatic pin pressing device, which differs from Example 1 in that the types of X-axis drive components and Y-axis drive components are different, as detailed below.

[0055] Reference Figure 7The type of X-axis drive is an X-axis linear motor 22. The stator of the X-axis drive is fixedly installed on the equipment frame 1 along the X-axis linear direction. The head base plate 51 of the press head 5 is fixedly installed on the mover of the X-axis drive so that the press head 5 can be driven to move horizontally along the X-axis direction by the X-axis drive.

[0056] The Y-axis drive is a Y-axis linear motor 32. The stator of the Y-axis drive is fixedly mounted on the equipment frame 1 along the Y-axis direction, and the machining slide 11 is fixedly mounted on the mover of the Y-axis drive so that the machining slide 11 can be driven to move horizontally along the Y-axis direction by the Y-axis drive.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
