Description

Technical Field

[0001] This invention belongs to the field of main reducer housing processing technology, and particularly relates to a hole processing device for the production of main reducer housings. Background Technology

[0002] The main reducer refers to the rear axle reducer in a car's rear axle. The rear axle reducer is an important component of the rear axle of a car. Its main function is to increase the torque from the transmission or universal joint, while reducing the speed and changing the direction of torque transmission.

[0003] During the processing of the main reducer housing, holes need to be drilled at the ends of the main reducer housing for installation and connection. An existing device for hole processing in the production of main reducer housings, with publication number CN114054807B, has two conveyor lines for loading and unloading the main reducer housing. A hole processing mechanism is located between the two conveyor lines. A clamping assembly holds a single material, which is then placed on a worktable by a transfer assembly. The hole processing mechanism then processes the material on the worktable. After processing, the transfer assembly transports the clamping assembly holding the material to a receiving assembly.

[0004] The above method can realize the feeding, drilling and unloading of the main reducer housing. However, the existing device is relatively complex, using two conveyor lines and setting up clamping and transfer components to transfer the main reducer housing, which results in high processing cost of the main reducer housing. In addition, the above device can only perform hole processing on one end of the main reducer housing. After completing the hole processing on one end of the main reducer housing, it is necessary to perform hole processing on the other end of the main reducer housing again, resulting in low efficiency of hole processing of the main reducer housing. Summary of the Invention

[0005] The purpose of this invention is to provide a hole-machining device for the production of main reducer housings, which aims to solve the problems of existing hole-machining devices for the production of main reducer housings being complex in structure, high in manufacturing cost, and low in efficiency in hole machining of main reducer housings.

[0006] This invention is implemented as follows: a hole-machining device for producing a main reducer housing includes a worktable and a support frame fixed on the worktable. It also includes a belt conveyor fixed to the upper end of the worktable and a tilting frame rotatably connected to the support frame. The tilting frame is located above the belt conveyor. A tilting assembly is provided on the support frame, which drives the tilting frame to rotate. Two clamping blocks are horizontally slidably connected to the inner wall of the tilting frame. A driving assembly is provided on the tilting frame, which drives the two clamping blocks to move towards or away from each other. A lifting mechanism is provided on the worktable, which drives the main reducer housing on the belt conveyor to move up and down. A drilling mechanism is provided on the top of the support frame, which drills holes at the ends of the main reducer housing.

[0007] In a further technical solution, the drive assembly includes a sliding frame slidably connected to the flipping frame, a first pushing part is provided on the sliding frame, a second telescopic cylinder is fixed on the flipping frame, the telescopic end of the second telescopic cylinder passes through the flipping frame and is fixed on the sliding frame, a second pushing part is provided on the clamping block, the second pushing part cooperates with the first pushing part, a tension spring is fixed at one end of the clamping block, and the end of the tension spring is fixed on the inner wall of the flipping frame.

[0008] A further technical solution is that the lifting mechanism includes a concave support plate that slides vertically on the worktable, and a telescopic cylinder fixed at the bottom of the worktable. The telescopic end of the telescopic cylinder extends upward through the worktable and is fixedly connected to the concave support plate.

[0009] In a further technical solution, the flipping assembly includes a guide groove 1 vertically arranged on the inner wall of the support frame, a rack slidably connected in the guide groove 1, a telescopic cylinder 3 fixed on the inner wall of the support frame, the telescopic end of the telescopic cylinder 3 being connected to one end of the rack, and a gear installed on the flipping frame, the gear meshing with the rack.

[0010] A further technical solution includes a sliding shaft fixed on the side wall of the clamping block, a ratchet rack mounted on the sliding shaft, a second guide groove on the flipping frame, a guide block slidably connected in the second guide groove, meshing teeth and a compression spring fixed at both ends of the guide block respectively, the end of the compression spring fixed in the second guide groove, and a transmission assembly on the flipping frame. When the concave support plate moves upward, the transmission assembly overcomes the elastic force of the compression spring and drives the guide block away from the ratchet rack.

[0011] In a further technical solution, the transmission assembly includes a push block slidably connected on the tilting frame, and a mating groove provided on the guide block. The mating groove is provided with an inclined surface, which mates with the push block. A push rod is fixed on the concave support plate.

[0012] A further technical solution is provided, wherein a sliding groove is horizontally provided on the tilting frame, and an annular slide is slidably connected in the sliding groove. The annular slide is fixed to the end of the sliding shaft, and multiple transmission shafts are uniformly fixed in an annular pattern on the annular slide. Multiple mating holes I are uniformly provided in an annular pattern on the side wall of the support frame, and multiple mating holes II are uniformly provided in an annular pattern on the gear. The gear is rotatably connected to the tilting frame.

[0013] A further technical solution includes a drilling mechanism comprising an clearance groove on the top of a support frame and a swing rod rotatably connected to the upper end of the support frame. A motor is fixed to the support frame, and the rotating end of the motor is connected to the swing rod. A mounting block is slidably connected to the swing rod along its length. A lead screw is rotatably connected to the swing rod and threadedly connected to the mounting block. A servo motor is mounted on the swing rod, and the rotating end of the servo motor is connected to the lead screw. Two guide shafts are vertically slidably connected to the mounting block, and a mounting frame is fixed to the lower end of the two guide shafts. A telescopic cylinder is fixed to the upper end of the mounting block, and the telescopic end of the telescopic cylinder is connected to the mounting frame. A drill bit is rotatably connected to the lower end of the mounting frame, and a second motor is mounted on the mounting frame, with the rotating end of the second motor connected to the drill bit.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. This application designs only one belt conveyor device to complete the loading and unloading of the main reducer housing, thereby making the device simpler and reducing manufacturing costs;

[0016] 2. The design of the flipping component allows for the machining of the holes at both ends of the main reducer housing in a single loading and clamping process, thereby reducing the number of loading, unloading, and clamping operations and improving the efficiency of hole machining in the main reducer housing.

[0017] 3. When the clamping block needs to release the main reducer housing, the concave support plate moves upward and supports the bottom of the main reducer housing. At this time, the concave support plate drives the push rod to push the push block upward. The push block pushes the guide block through the inclined surface, thereby causing the guide block to overcome the elastic force of the compression spring and causing the meshing teeth to not mesh with the ratchet rack, thus releasing the restriction of the clamping block to release the main reducer housing. Through this design, the clamping block can only release the main reducer housing when the concave support plate moves upward and supports the bottom of the main reducer housing, avoiding the risk of the main reducer housing falling from a height.

[0018] 4. When the two clamping blocks clamp the main reducer housing, the clamping blocks drive the annular slide away from the side wall of the support frame through the sliding shaft. The annular slide drives the transmission shaft to disengage from the first mating hole and insert the transmission shaft into the second mating hole. At this time, the rotation restriction of the tilting frame is released, and the gear can drive the tilting frame to rotate. Under this design, the tilting frame can only rotate when the two clamping blocks clamp the main reducer housing, thereby improving the safety of the main reducer housing hole machining.

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0032] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0033] like Figures 1-5 As shown in the figure, a hole processing device for producing a main reducer housing according to an embodiment of the present invention includes a worktable 101 and a support frame 103 fixed on the worktable 101. It also includes a belt conveyor 102 fixed to the upper end of the worktable 101 and a tilting frame 104 rotatably connected to the support frame 103. The tilting frame 104 is located above the belt conveyor 102. A tilting assembly 4 is provided on the support frame 103, which drives the tilting frame 104 to rotate. Two clamping blocks 105 are horizontally slidably connected to the inner wall of the tilting frame 104. A driving assembly 3 is provided on the tilting frame 104, which drives the two clamping blocks 105 to move towards or in opposite directions. A lifting mechanism 2 is provided on the worktable 101, which drives the main reducer housing on the belt conveyor 102 to move up and down. A drilling mechanism 8 is provided on the top of the support frame 103, which drills holes at the end of the main reducer housing.

[0034] In this embodiment of the invention, during use, the main reducer housing is placed on the belt conveyor 102, which transports the main reducer housing until it reaches below the support frame 103. The lifting mechanism 2 then moves the main reducer housing upwards, positioning it between two clamping blocks 105. The drive assembly 3 then moves the two clamping blocks 105 towards each other, clamping the sidewalls of the main reducer housing. The upper and lower clamps of the two clamping blocks 105... The holding parts are aligned with the sidewall contours of the upper and lower parts of the main reducer housing. Due to the eccentric design of the upper and lower ends of the main reducer housing, the two clamping blocks 105 can correct the position of the main reducer housing when clamping it. The drilling mechanism 8 drills a hole at the upper end of the main reducer housing. After the hole at one end of the main reducer housing is machined, the lifting mechanism 2 moves downward, and the flipping assembly 4 drives the flipping frame 104 to rotate. The flipping frame 104 drives the main reducer housing to flip, thereby making the other end of the main reducer housing face upward for drilling. Mechanism 8 then drills holes at the other end of the main reducer housing. After the holes at both ends of the main reducer housing are machined, the flipping assembly 4 drives the flipping frame 104 to reverse, and the flipping frame 104 drives the main reducer housing to reverse and reset. The lifting mechanism 2 moves upward and supports the main reducer housing. The drive assembly 3 drives the two clamping blocks 105 to move in the opposite direction, thereby causing the two clamping blocks 105 to release the main reducer housing. The lifting mechanism 2 drives the machined main reducer housing to move downward and fall onto the belt conveyor 102. The belt conveyor 102 drives the machined main reducer housing to unload, thus completing one round of hole machining of the main reducer housing. This application only designs one belt conveyor 102 to complete the loading and unloading of the main reducer housing, thus making the device simpler and reducing manufacturing costs. Moreover, the design of the flipping assembly 4 can complete the machining of the holes at both ends of the main reducer housing in one loading and clamping state, thereby reducing the number of loading, unloading and clamping of the main reducer housing, thereby improving the efficiency of hole machining of the main reducer housing.

[0035] like Figures 1-6 As shown, in a preferred embodiment of the present invention, the driving assembly 3 includes a sliding frame 301 slidably connected to the flipping frame 104. A first pushing part 302 is provided on the sliding frame 301. A second telescopic cylinder 303 is fixed on the flipping frame 104. The telescopic end of the second telescopic cylinder 303 passes through the flipping frame 104 and is fixed on the sliding frame 301. A second pushing part 304 is provided on the clamping block 105. The second pushing part 304 cooperates with the first pushing part 302. A tension spring 305 is fixed at one end of the clamping block 105. The end of the tension spring 305 is fixed on the inner wall of the flipping frame 104.

[0036] In this embodiment of the invention, the mating surfaces of the first pushing part 302 and the second pushing part 304 are inclined surfaces. When clamping the main reducer housing, the second telescopic cylinder 303 retracts, and the second telescopic cylinder 303 drives the sliding frame 301 to move towards the flipping frame 104. The first pushing part 302 on the sliding frame 301 pushes the second pushing part 304, and the second pushing part 304 overcomes the elastic force of the tension spring 305 and drives the clamping block 105 to move, thereby causing the two clamping blocks 105 to move towards each other. When the main reducer housing is released, the second telescopic cylinder 303 extends, and the second telescopic cylinder 303 drives the sliding frame 301 away from the flipping frame 104. The first pushing part 302 on the sliding frame 301 does not contact the second pushing part 304, and the tension spring 305 and the clamping block 105 move in the opposite direction, thereby causing the two clamping blocks 105 to release the main reducer housing.

[0037] like Figure 1-Figure 4 As shown, in a preferred embodiment of the present invention, the lifting mechanism 2 includes a concave support plate 201 that slides vertically on the workbench 101, and a telescopic cylinder 202 fixed at the bottom of the workbench 101. The telescopic end of the telescopic cylinder 202 extends upward through the workbench 101 and is fixedly connected to the concave support plate 201.

[0038] In this embodiment of the invention, the belt conveyor 102 is located inside the concave support plate 201. When the main reducer housing moves above the concave support plate 201, the telescopic cylinder 202 extends, and the telescopic cylinder 202 drives the concave support plate 201 to move upward, and the concave support plate 201 drives the main reducer housing to move upward; when the telescopic cylinder 202 retracts, the telescopic cylinder 202 drives the concave support plate 201 to move downward, and the concave support plate 201 drives the main reducer housing to move downward.

[0039] like Figures 1-5 As shown, in a preferred embodiment of the present invention, the flipping assembly 4 includes a guide groove 401 vertically arranged on the inner wall of the support frame 103, a rack 402 slidably connected in the guide groove 401, a telescopic cylinder 403 fixed on the inner wall of the support frame 103, the telescopic end of the telescopic cylinder 403 being connected to one end of the rack 402, and a gear 404 mounted on the flipping frame 104, the gear 404 meshing with the rack 402.

[0040] In this embodiment of the invention, the gear 404 is fixed on the tilting frame 104, the telescopic cylinder 403 extends and retracts, the telescopic cylinder 403 drives the rack 402 to move up and down, the rack 402 drives the gear 404 to rotate, and the gear 404 drives the tilting frame 104 to rotate.

[0041] like Figures 1-10As shown, in a preferred embodiment of the present invention, a sliding shaft 501 is fixed on the side wall of the clamping block 105, a ratchet rack 502 is mounted on the sliding shaft 501, a guide groove 503 is provided on the flipping frame 104, a guide block 504 is slidably connected in the guide groove 503, and meshing teeth 505 and compression springs 506 are respectively fixed at both ends of the guide block 504, with the end of the compression spring 506 fixed in the guide groove 503. The flipping frame 104... A transmission assembly 6 is provided on the concave support plate 201. When the concave support plate 201 moves upward, the transmission assembly 6 overcomes the elastic force of the compression spring 506 and drives the guide block 504 away from the ratchet rack 502. The transmission assembly 6 includes a push block 601 slidably connected to the flipping frame 104 and a mating groove 602 provided on the guide block 504. An inclined surface 603 is provided on the mating groove 602, and the inclined surface 603 cooperates with the push block 601. A push rod 604 is fixed on the concave support plate 201.

[0042] In this embodiment of the invention, the compression spring 506 pushes the guide block 504, which in turn drives the meshing teeth 505 to mesh with the ratchet rack 502, thereby restricting the sliding shaft 501 from moving towards the inner wall of the support frame 103. This restricts the clamping block 105 from moving towards the inner wall of the support frame 103 and prevents the two clamping blocks 105 from moving away from each other. During the clamping process of the main reducer housing, damage to the telescopic cylinder 303 is avoided, which could cause the main reducer housing to be accidentally released. When the clamping block 105 needs to release the main reducer housing, the concave support plate 201 moves upward and supports the main reducer housing. At the bottom of the main reducer housing, the concave support plate 201 drives the push rod 604 to push the push block 601 upward. The push block 601 pushes the guide block 504 through the inclined surface 603, thereby causing the guide block 504 to overcome the elastic force of the compression spring 506 and drive the meshing teeth 505 to not mesh with the ratchet rack 502, thereby releasing the clamping block 105 from the restriction of the main reducer housing. Through this design, when the concave support plate 201 moves upward and supports the bottom of the main reducer housing, the clamping block 105 can release the main reducer housing, avoiding the risk of the main reducer housing falling from a height.

[0043] like Figures 1-8 As shown, in a preferred embodiment of the present invention, a sliding groove 701 is horizontally provided on the flipping frame 104, and an annular slide 702 is slidably connected in the sliding groove 701. The annular slide 702 is fixed to the end of the sliding shaft 501. A plurality of transmission shafts 703 are uniformly fixed in an annular shape on the annular slide 702. A plurality of mating holes 704 are uniformly provided in an annular shape on the side wall of the support frame 103. A plurality of mating holes 705 are uniformly provided in an annular shape on the gear 404. The gear 404 is rotatably connected to the flipping frame 104.

[0044] In this embodiment of the invention, when the two clamping blocks 105 are not clamping the main reducer housing, the clamping blocks 105 drive the annular slide 702 to approach the side wall of the support frame 103 via the sliding shaft 501. The annular slide 702 drives the transmission shaft 703 to insert into the first mating hole 704, and the transmission shaft 703 disengages from the second mating hole 705. At this time, the tilting frame 104 is restricted from rotating, preventing the tilting frame 104 from accidentally rotating and knocking the main reducer housing off the concave support plate 201 when the clamping blocks 105 are not clamping the main reducer housing. Furthermore, due to accidental contact, the telescopic cylinder 403 extends and retracts, and the gear 404 only rotates freely relative to the tilting frame 104, thereby avoiding… To prevent rigid collisions, the device is protected. When the two clamping blocks 105 clamp the main reducer housing, the clamping blocks 105 drive the annular slide 702 away from the side wall of the support frame 103 via the sliding shaft 501. The annular slide 702 drives the transmission shaft 703 to disengage from the first mating hole 704 and insert the transmission shaft 703 into the second mating hole 705. At this time, the rotation restriction of the tilting frame 104 is released, and the gear 404 can drive the tilting frame 104 to rotate. Under this design, the tilting frame 104 can only rotate when the two clamping blocks 105 clamp the main reducer housing, thereby improving the safety of the main reducer housing hole machining.

[0045] like Figure 1 , Figure 2 and Figure 11 As shown, in a preferred embodiment of the present invention, the drilling mechanism 8 includes a clearance groove 801 provided on the top of the support frame 103, and a swing rod 802 rotatably connected to the upper end of the support frame 103. A motor 803 is fixed on the support frame 103, and the rotating end of the motor 803 is connected to the swing rod 802. A mounting block 804 is slidably connected to the swing rod 802 along its length direction, and a lead screw 808 is rotatably connected to the swing rod 802. The lead screw 808 is threadedly connected to the mounting block 804. A servo motor is installed on the mounting block 804, and the rotating end of the servo motor is connected to the lead screw 808. Two guide shafts 809 are vertically slidably connected on the mounting block 804, and a mounting frame 805 is fixed to the lower end of the two guide shafts 809. A telescopic cylinder 810 is fixed to the upper end of the mounting block 804, and the telescopic end of the telescopic cylinder 810 is connected to the mounting frame 805. A drill bit 807 is rotatably connected to the lower end of the mounting frame 805, and a motor 806 is installed on the mounting frame 805. The rotating end of the motor 806 is connected to the drill bit 807.

[0046] In this embodiment of the invention, motor 803 drives the swing arm 802 to rotate, and the swing arm 802 drives the mounting block 804, mounting frame 805 and drill bit 807 to rotate, thereby placing the hole machining position of the main reducer housing at the rotation radius of the drill bit 807. The servo motor drives the lead screw 808 to rotate, and the lead screw 808 drives the mounting block 804 to move through the threaded transmission. The mounting block 804 drives the mounting frame 805 and drill bit 807 to move, thereby adjusting the rotation radius of the drill bit 807 so that the drill bit 807 is above the hole machining position of the main reducer housing. Motor 806 drives the drill bit 807 to rotate, and telescopic cylinder 810 extends. Telescopic cylinder 810 drives the mounting frame 805, guide shaft 809 and drill bit 807 to move downward, and the rotating drill bit 807 performs hole machining on the upper end of the main reducer housing.

[0047] The above embodiments of the present invention provide a hole processing device for the production of a main reducer housing. In use, the main reducer housing is placed on a belt conveyor 102, which transports the housing until it reaches below a support frame 103. Then, a first telescopic cylinder 202 extends, causing a concave support plate 201 to move upwards. This concave support plate 201 then moves the main reducer housing upwards, positioning it between two clamping blocks 105. A second telescopic cylinder 303 retracts, causing a sliding frame 301 to move towards a tilting frame 104. A first pushing part 302 on the sliding frame 301 pushes a second pushing part 304, which overcomes the elastic force of the tension spring 305 and... The moving clamping block 105 moves, causing the two clamping blocks 105 to move towards each other. The two clamping blocks 105 clamp the side wall of the main reducer housing. The upper and lower clamping parts of the two clamping blocks 105 are consistent with the contours of the upper and lower side walls of the main reducer housing. Due to the eccentric design of the upper and lower ends of the main reducer housing, the two clamping blocks 105 can correct the position of the main reducer housing when clamping it. The drilling mechanism 8 drills a hole at the upper end of the main reducer housing. After the hole at one end of the main reducer housing is machined, the telescopic cylinder 202 retracts. The telescopic cylinder 202 drives the concave support plate 201 to move downward. The concave support plate 201 drives the main reducer housing to move downward. The compression spring 506 pushes the guide block 504, and the guide block 504 engages the meshing mechanism. The tooth 505 meshes with the ratchet rack 502, thereby restricting the sliding shaft 501 from moving towards the inner wall of the support frame 103, thus restricting the clamping block 105 from moving towards the inner wall of the support frame 103, and restricting the two clamping blocks 105 from moving away from each other. The telescopic cylinder 3 403 extends, and the telescopic cylinder 3 403 drives the rack 402 to move upward. The rack 402 drives the gear 404 to rotate, and the gear 404 drives the tilting frame 104 to rotate. The tilting frame 104 drives the main reducer housing to tilt, thereby making the other end of the main reducer housing face upward. The drilling mechanism 8 then drills a hole at the other end of the main reducer housing. After the holes at both ends of the main reducer housing are processed, the telescopic cylinder 3 403 retracts, and the tilting frame 104 drives the main reducer housing to reverse and reset. The telescopic cylinder 1 202 extends, and the telescopic cylinder 1 2... 02 drives the concave support plate 201 to move upward, supporting the main reducer housing. At this time, the concave support plate 201 drives the push rod 604 to push the push block 601 upward. The push block 601 pushes the guide block 504 through the inclined surface 603, thereby causing the guide block 504 to overcome the elastic force of the compression spring 506 and causing the meshing teeth 505 to not mesh with the ratchet rack 502. This releases the clamping block 105 from the restriction of the main reducer housing, and the telescopic cylinder 203 extends. The telescopic cylinder 203 drives the sliding frame 301 away from the tilting frame 104. The push part 302 on the sliding frame 301 does not contact the push part 204, and the tension spring 305 clamping block 105 moves in the opposite direction, thereby causing the two clamping blocks 105 to release the main reducer housing. The telescopic cylinder 202 retracts.Telescopic cylinder 202 drives concave support plate 201 downwards. Concave support plate 201 then moves the machined main reducer housing downwards and onto belt conveyor device 102. Belt conveyor device 102 then unloads the machined main reducer housing, thus completing one round of hole machining on the main reducer housing. This application only requires one belt conveyor device 102 to complete the loading and unloading of the main reducer housing, making the device simpler and reducing manufacturing costs. Furthermore, the design of the flipping component 4 allows for the machining of the holes at both ends of the main reducer housing during a single loading and clamping process, reducing the number of loading, unloading, and clamping operations and thus improving the efficiency of hole machining on the main reducer housing.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
