Technical Field

[0001] The present invention belongs to the technical field of the machining of the main reducer housing, and particularly relates to a hole machining device for the production of the main reducer housing. Background Art

[0002] The main reducer refers to the rear axle reducer in the rear axle of an automobile. The rear axle reducer is an important component in the rear axle of an automobile, and its main function is to increase the torque from the transmission or the universal drive device, while reducing the rotational speed and changing the transmission direction of the torque.

[0003] When machining the main reducer housing, it is necessary to drill holes at the end of the main reducer housing for the installation and connection of the main reducer housing. There is a hole machining device for the production of the main reducer housing with the publication number of CN114054807B. This device is provided with two conveying lines, which are respectively used for the feeding and discharging of the main reducer housing. At the same time, a hole machining mechanism is arranged between the two conveying lines. After clamping a single material by the clamping assembly and driving the material to be placed on the workbench by the transfer assembly, the material on the workbench is processed by the hole machining mechanism. After the processing is completed, the clamping assembly clamping the material is transported to the receiving assembly by the transfer assembly again.

[0004] The above method can realize the feeding, hole drilling and discharging of the main reducer housing. However, the existing device is relatively complex, with two conveying lines, and clamping assemblies and transfer assemblies are arranged to transfer the main reducer housing, resulting in a high processing cost of the main reducer housing. Moreover, the above device can only perform hole machining on one end of the main reducer housing. After the hole machining of one end of the main reducer housing is completed, it is necessary to perform hole machining on the other end of the main reducer housing again, resulting in low efficiency of the hole machining of the main reducer housing.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

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

[0016] 2. The design of the flip assembly can complete the processing 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 the main reducer housing hole processing;

[0017] 3. When the clamping block is required to release the main reducer housing, the concave support plate moves upward and drags the bottom of the main reducer housing. At this time, the concave support plate drives the push rod to push the push block upward, and the push block pushes the guide block through the inclined surface, so that the guide block overcomes the elastic force of the compression spring and drives the meshing teeth to not mesh with the ratchet bar, thereby releasing the restriction of the clamping block to release the main reducer housing. Through the design here, the clamping block can release the main reducer housing only when the concave support plate moves upward and drags 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 sliding frame away from the side wall of the support frame through the sliding shaft. The annular sliding frame drives the transmission shaft out of the first mating hole, and the transmission shaft is inserted into the second mating hole. At this time, the rotation restriction of the flipping frame is released, and the gear can drive the flipping frame to rotate. Under this design, the flipping frame can only rotate when the two clamping blocks clamp the main reducer housing, thereby improving the safety of hole machining of the main reducer housing.

Detailed implementation manners

[0031] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present 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 only used to explain the present invention and are not used to limit the present invention.

[0032] The following describes in detail the specific implementation of the present invention with reference to specific embodiments.

[0033] As Figures 1 - 5 shown, a hole machining device for the production of a main reducer housing provided by an embodiment of the present invention includes a workbench 101 and a support frame 103 fixed on the workbench 101, and further includes: a belt conveyor 102 fixed to the upper end of the workbench 101, and a flipping frame 104 rotatably connected to the support frame 103. The flipping frame 104 is located above the belt conveyor 102. A flipping assembly 4 is provided on the support frame 103, and the flipping assembly 4 is used to drive the flipping frame 104 to rotate; two clamping blocks 105 are horizontally slidably connected to the inner wall of the flipping frame 104, and a driving assembly 3 is provided on the flipping frame 104. The driving assembly 3 is used to drive the two clamping blocks 105 to move towards or away from each other; a lifting mechanism 2 is provided on the workbench 101, and the lifting mechanism 2 is used to drive the main reducer housing on the belt conveyor 102 to move up and down; a drilling mechanism 8 is provided at the top of the support frame 103, and the drilling mechanism 8 is used to drill the end of the main reducer housing.

[0034] In the embodiment of the present invention, during use, the main reducer housing is placed on the belt conveyor 102. The belt conveyor 102 conveys the main reducer housing until the main reducer housing is conveyed below the support frame 103. The lifting mechanism 2 drives the main reducer housing to move upward, so that the main reducer housing moves between the two clamping blocks 105. The driving assembly 3 drives the two clamping blocks 105 to move towards each other, and 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 side wall contours of the upper and lower parts of the main reducer housing. And due to the eccentric design of the upper and lower ends of the main reducer housing, when the two clamping blocks 105 clamp the main reducer housing, the position of the main reducer housing can be corrected. The drilling mechanism 8 drills the upper end of the main reducer housing. After the hole machining at one end of the main reducer housing is completed, 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, so that the other end of the main reducer housing faces upward. Then the drilling mechanism 8 drills the other end of the main reducer housing. After the hole machining at both ends of the main reducer housing is completed, the flipping assembly 4 drives the flipping frame 104 to reverse. 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 driving assembly 3 drives the two clamping blocks 105 to move in the opposite direction, so that the two clamping blocks 105 release the main reducer housing. The lifting mechanism 2 drives the processed main reducer housing to move downward and fall on the belt conveyor 102. The belt conveyor 102 drives the processed main reducer housing to discharge, thus completing one round of hole machining of the main reducer housing. In this application, only one belt conveyor 102 is designed to complete the loading and unloading of the main reducer housing, which makes the device more concise, reduces the manufacturing cost. And the design of the flipping assembly 4 can complete the hole machining at both ends of the main reducer housing in the state of one-time loading and clamping of the main reducer housing, thereby reducing the number of loading, unloading and clamping of the main reducer housing, and improving the efficiency of hole machining of the main reducer housing.

[0035] As Figures 1 - 6 shown, as 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 portion 302 is provided on the sliding frame 301. A second telescopic cylinder 303 is fixed to the flipping frame 104. The telescopic end of the second telescopic cylinder 303 penetrates through the flipping frame 104 and is fixed to the sliding frame 301. A second pushing portion 304 is provided on the clamping block 105. The second pushing portion 304 cooperates with the first pushing portion 302. One end of the clamping block 105 is fixed with a tension spring 305. The end of the tension spring 305 is fixed to the inner wall of the flipping frame 104.

[0036] In an embodiment of the present invention, the mating surface of the first pushing part 302 and the second pushing part 304 is an inclined surface. When clamping the main reducer housing, the second telescopic cylinder 303 contracts, 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, so that the two clamping blocks 105 move towards each other; when releasing the main reducer housing, the second telescopic cylinder 303 extends, and the second telescopic cylinder 303 drives the sliding frame 301 to move 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 drives the clamping block 105 to move in the reverse direction, so that the two clamping blocks 105 release the main reducer housing.

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

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

[0039] As Figures 1 - 5 shown, as a preferred embodiment of the present invention, the flipping assembly 4 includes a first guiding groove 401 vertically arranged on the inner wall of the support frame 103. A rack 402 is slidably connected in the first guiding groove 401. A third telescopic cylinder 403 is fixed to the inner wall of the support frame 103. The telescopic end of the third telescopic cylinder 403 is connected to one end of the rack 402. A gear 404 is installed on the flipping frame 104, and the gear 404 meshes with the rack 402.

[0040] In an embodiment of the present invention, the gear 404 is fixed on the flipping frame 104. The third telescopic cylinder 403 expands and contracts, the third 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 flipping frame 104 to rotate.

[0041] As Figures 1 - 10As shown, as 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 installed on the sliding shaft 501. A second guiding groove 503 is provided on the turning frame 104. A guiding block 504 is slidably connected in the second guiding groove 503. Meshing teeth 505 and a compression spring 506 are respectively fixed at both ends of the guiding block 504. The end of the compression spring 506 is fixed in the second guiding groove 503. A transmission assembly 6 is provided on the turning frame 104. When the concave supporting plate 201 moves upward, the transmission assembly 6 overcomes the elastic force of the compression spring 506 and drives the guiding block 504 away from the ratchet rack 502. The transmission assembly 6 includes a pushing block 601 slidably connected to the turning frame 104 and a mating groove 602 provided on the guiding block 504. An inclined surface 603 is provided on the mating groove 602. The inclined surface 603 cooperates with the pushing block 601. A push rod 604 is fixed on the concave supporting plate 201.

[0042] In the embodiment of the present invention, the compression spring 506 pushes the guiding block 504. The guiding block 504 drives the meshing teeth 505 to engage with the ratchet rack 502, thereby restricting the sliding shaft 501 from moving towards the inner wall of the support frame 103, and 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. During the clamping process of the main reducer housing, to avoid the main reducer housing being accidentally loosened due to the damage of the second telescopic cylinder 303. When the clamping block 105 needs to loosen the main reducer housing, the concave supporting plate 201 moves upward and drags the bottom of the main reducer housing. At this time, the concave supporting plate 201 drives the push rod 604 to push the pushing block 601 upward. The pushing block 601 pushes the guiding block 504 through the inclined surface 603, so that the guiding block 504 overcomes the elastic force of the compression spring 506 and drives the meshing teeth 505 not to engage with the ratchet rack 502, thereby releasing the restriction on the clamping block 105 from loosening the main reducer housing. Through this design, when the concave supporting plate 201 moves upward and drags the bottom of the main reducer housing, the clamping block 105 can loosen the main reducer housing, avoiding the risk of the main reducer housing falling from a height.

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

[0044] In the embodiment of the present invention, when the two clamping blocks 105 do not clamp the main reducer housing, the clamping block 105 drives the annular slide 702 to approach the side wall of the support frame 103 through 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 turning frame 104 is restricted from rotating, avoiding the accidental rotation of the turning frame 104 and knocking down the main reducer housing on the concave support plate 201 when the clamping block 105 does not clamp the main reducer housing. And at this time, due to accidental touch, the telescopic cylinder three 403 expands and contracts, and the gear 404 only idles relative to the turning frame 104, thereby avoiding rigid collision of the device and protecting the device; when the two clamping blocks 105 clamp the main reducer housing, the clamping block 105 drives the annular slide 702 away from the side wall of the support frame 103 through the sliding shaft 501. The annular slide 702 drives the transmission shaft 703 to disengage from the first mating hole 704, and the transmission shaft 703 inserts into the second mating hole 705. At this time, the rotation restriction of the turning frame 104 is released, and the gear 404 can drive the turning frame 104 to rotate. Under this design, the turning frame 104 can only rotate when the two clamping blocks 105 clamp the main reducer housing, thereby improving the safety of the hole machining of the main reducer housing.

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

[0046] In an embodiment of the present invention, the first motor 803 drives the swing rod 802 to rotate, the swing rod 802 drives the mounting block 804, the mounting frame 805 and the drill bit 807 to rotate, so that the hole machining position of the main reducer housing is located on 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 a screw drive manner. The mounting block 804 drives the mounting frame 805 and the drill bit 807 to move, thereby adjusting the rotation radius of the drill bit 807 to make the drill bit 807 above the hole machining position of the main reducer housing. The second motor 806 drives the drill bit 807 to rotate, the fourth telescopic cylinder 810 extends, and the fourth telescopic cylinder 810 drives the mounting frame 805, the guide shaft 809 and the 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] In the above embodiments of the present invention, a hole machining device for the production of the main reducer housing is provided. When in use, the main reducer housing is placed on the belt conveyor 102, and the belt conveyor 102 conveys the main reducer housing until the main reducer housing is conveyed below the support frame 103. The first telescopic cylinder 202 extends, and the first telescopic cylinder 202 drives the concave pallet 201 to move upward. The concave pallet 201 drives the main reducer housing to move upward, so that the main reducer housing moves between the two clamping blocks 105. The second telescopic cylinder 303 contracts, 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. The second pushing part 304 overcomes the elastic force of the tension spring 305 and drives the clamping block 105 to move, so that the two clamping blocks 105 move towards each other, and 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 side wall contours of the upper and lower parts of the main reducer housing. And because the upper end and the lower end of the main reducer housing are eccentrically designed, when the two clamping blocks 105 clamp the main reducer housing, the position of the main reducer housing can be corrected. The drilling mechanism 8 drills the upper end of the main reducer housing. After the hole machining at one end of the main reducer housing is completed, the first telescopic cylinder 202 contracts, and the first telescopic cylinder 202 drives the concave pallet 201 to move downward. The concave pallet 201 drives the main reducer housing to move downward. The compression spring 506 pushes the guide block 504, and the guide block 504 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, 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 third telescopic cylinder 403 extends, and the third telescopic cylinder 403 drives the rack 402 to move upward. The rack 402 drives the gear 404 to rotate, and the gear 404 drives the flipping frame 104 to rotate. The flipping frame 104 drives the main reducer housing to flip, so that the other end of the main reducer housing faces upward. The drilling mechanism 8 then drills the other end of the main reducer housing. After the hole machining at both ends of the main reducer housing is completed, the third telescopic cylinder 403 contracts, the flipping frame 104 drives the main reducer housing to reverse and reset. The first telescopic cylinder 202 extends, and the first telescopic cylinder 202 drives the concave pallet 201 to move upward. The concave pallet 201 supports the main reducer housing. At this time, the concave pallet 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, so that the guide block 504 overcomes the elastic force of the compression spring 506 and drives the meshing teeth 505 not to mesh with the ratchet rack 502, thereby releasing the restriction on the clamping block 105 from loosening the main reducer housing. The second telescopic cylinder 303 extends, and the second telescopic cylinder 303 drives the sliding frame 301 to move away from the flipping frame 104. The first pushing part 302 on the sliding frame 301 does not contact the second pushing part 304. The tension spring 305 drives the clamping block 105 to move in the reverse direction, so that the two clamping blocks 105 loosen the main reducer housing. The first telescopic cylinder 202 contracts,The telescopic cylinder 202 drives the concave-shaped support plate 201 to move downward. The concave-shaped support plate 201 drives the processed main reducer housing to move downward and land on the belt conveyor 102. The belt conveyor 102 drives the processed main reducer housing to unload, thereby completing one round of hole machining of the main reducer housing. In this application, only one belt conveyor 102 is designed to complete the loading and unloading of the main reducer housing, thereby making the device more concise, reducing the manufacturing cost. Moreover, the design of the flipping assembly 4 can complete the hole machining of both ends of the main reducer housing in the state of one-time loading and clamping of the main reducer housing, thereby reducing the number of loading, unloading and clamping of the main reducer housing, and thus improving the efficiency of hole machining of the main reducer housing.
