Description

Technical Field

[0001] This utility model relates to the field of bridge shell processing technology, and in particular to a placement fixture for bridge shell processing. Background Technology

[0002] The axle housing is the assembly base for mounting the main reducer, differential, half-shafts, and wheels. Its main function is to support and protect the main reducer, differential, and half-shafts. During the machining of the axle housing half-piece, it is necessary to ensure that the machined surface is horizontal.

[0003] The prior art, patent number CN 217122259 U, discloses a combination tooling for processing half of a bridge housing. It uses two sets of support components and two sets of clamping components to support and clamp the middle part of the bridge housing and one end of the bridge housing (the non-processing end), keeping the other end of the bridge housing (the processing end) horizontal. After one end of the bridge housing is processed, the support components and clamping components must first be disassembled, then the two ends of the bridge housing are swapped, and then the support components and clamping components are re-fixed to process the other end of the bridge housing. However, the disassembly process of the support components and clamping components is relatively cumbersome, and the operation of swapping the two ends of the heavy bridge housing is not easy, resulting in low processing efficiency of the bridge housing.

[0004] Therefore, it is necessary to propose a placement fixture for axle housing processing to improve the processing efficiency of axle housings. Utility Model Content

[0005] The purpose of this invention is to solve the problem of existing tooling affecting the processing efficiency of bridge housings. A placement tooling for bridge housing processing is provided.

[0006] The technical solution of this utility model is:

[0007] A placement fixture for processing bridge housings includes a frame, a clamping mechanism on the frame, and a rotating mechanism between the clamping mechanism and the frame, the rotating mechanism driving the clamping mechanism to rotate.

[0008] It also includes a first pressure bar and a second pressure bar with telescopic function. The first pressure bar and the second pressure bar are respectively located on both sides of the clamping mechanism. The frame is fixedly connected to a first lifting device and a second lifting device. The first lifting device drives the first pressure bar to rise and fall, and the second lifting device drives the second pressure bar to rise and fall.

[0009] Furthermore, the clamping mechanism includes a housing and a clamp. The clamp is located inside the housing and is coaxially mounted with the housing. An annular slide rail is coaxially provided inside the housing. The clamp is slidably connected to the housing through the annular slide rail. Through the annular slide rail, the clamp can rotate along the axis, thereby realizing the up-and-down flipping of the workpiece or adjusting the tilt angle of the workpiece. In some cases, when it is necessary to process the bottom surface or a certain side of the workpiece, the workpiece can be flipped without the worker having to manually disassemble it or open the clamp, which greatly improves the processing efficiency.

[0010] Furthermore, the housing includes an upper housing and a lower housing, which are rotatably connected and can be opened and closed. The clamp includes an upper clamp body and a lower clamp body, which open and close synchronously with the upper and lower housings, dividing the housing and clamp body into upper and lower parts, which makes it easier to open and close the clamping mechanism.

[0011] Furthermore, the rotating mechanism includes a first power unit and a turntable rotatably connected to the frame. One side of the turntable is fixedly connected to the lower housing, and the other side of the turntable is coaxially fixedly connected to a driven gear. The output end of the first power unit is fixedly connected to a driving gear, and the driven gear meshes with the driving gear. When the workpiece needs to be processed after processing one end, the first power unit can realize the automatic rotation of the turntable, thereby realizing the automatic rotation of the clamping mechanism, so that the two ends of the workpiece are swapped, and the other end of the workpiece is rotated to the processing station. The swapping of the workpiece no longer requires disassembling the tooling, nor does it require workers to move the workpiece, thus freeing up labor and greatly improving processing efficiency.

[0012] Furthermore, an external gear ring is fixedly connected to one side of the clamp body, and the external gear ring meshes with a drive gear. The drive gear is connected to a second power device, which is fixedly connected to the turntable. The second power device can drive the clamp body to rotate, realize the automatic up-and-down flipping of the workpiece and adjust the tilt angle, and improve processing efficiency.

[0013] Furthermore, it also includes a support plate placed between the first pressure bar and the clamping mechanism. The frame is fixedly connected to a third lifting device, which drives the support plate to rise and fall. The support plate is used to provide support at the processing end of the workpiece and at the bottom of the workpiece to ensure force balance.

[0014] Furthermore, a limiting plate is provided on the opposite side of the second pressure rod, and a limiting hole is opened on the limiting plate that is aligned with the second pressure rod. When the second pressure rod extends, it is inserted into the limiting hole. The second lifting device drives the limiting plate and the second pressure rod to rise and fall synchronously. The limiting plate can ensure the force balance at both ends of the second pressure rod and improve the structural stability.

[0015] Furthermore, the upper and lower housings are equipped with latches to prevent them from opening. The latches are located on opposite sides of the rotatable connection between the upper and lower housings. The latches prevent the housings from being accidentally opened when the clamping mechanism is under force.

[0016] Furthermore, both the upper and lower housings are equipped with locking mechanisms, which include limit posts and cylinders. The lower and upper clamping bodies are provided with fixing holes that match the limit posts. The cylinder drives the limit posts to insert into the fixing holes to fix the clamping bodies to the housings. The locking mechanism can provide a limit for the clamps and prevent the clamps from rotating relative to the housings when subjected to force, thus affecting the processing.

[0017] This utility model discloses a placement fixture for bridge housing processing. The workpiece on the clamping mechanism can rotate with the clamping mechanism, enabling the swapping of the two ends of the workpiece without disassembling the fixture or moving the workpiece, thus improving processing efficiency. The first and second pressure rods can press down on both ends of the workpiece, ensuring the stability of both ends of the workpiece during processing. The first and second pressure rods themselves have a telescopic function. Driven by the first and second lifting devices, the first and second pressure rods first rise and then extend, contacting the ends of the workpiece and providing a pressing function. When the first and second pressure rods first retract and then descend, they move away from the workpiece, thereby making room for the workpiece to rotate, facilitating the rotation mechanism to drive the clamping mechanism to rotate. The fixation of the workpiece by the first and second pressure rods is automatic lifting and telescopic, eliminating the need for manual disassembly, further improving processing efficiency. Compared with traditional technology, this technical solution avoids the tedious process of disassembling various components and also avoids the operation of workers moving the bridge housing, thus improving the processing efficiency of the bridge housing.

[0025] To make the technical means, technical features, utility model purpose and technical effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0026] Example 1:

[0027] like Figure 1 and Figure 2 As shown, this embodiment provides a placement fixture for axle housing processing. The placement fixture includes a frame 1, a clamping mechanism 25 on the frame 1, and a rotating mechanism 24 between the clamping mechanism 25 and the frame 1. The rotating mechanism 24 drives the clamping mechanism 25 to rotate. It also includes a first pressure rod 2 and a second pressure rod 3 with telescopic function. The first pressure rod 2 and the second pressure rod 3 are respectively disposed on both sides of the clamping mechanism 25. The frame 1 is fixedly connected to a first lifting device 4 and a second lifting device 5. The first lifting device 4 drives the first pressure rod 2 to rise and fall, and the second lifting device 5 drives the second pressure rod 3 to rise and fall. Preferably, the first pressure rod 2 and the second pressure rod 3 are electric cylinder telescopic rods, which are driven to extend and retract by an electric cylinder. The first lifting device 4 and the second lifting device 5 are pneumatic cylinders or hydraulic cylinders. The direction of the first pressure rod 2 is parallel to the axis of the clamp, and the second pressure rod 3 is placed horizontally and perpendicular to the axis of the clamp.

[0028] Preferably, the clamping mechanism 25 includes a housing and a clamp. The clamp is located inside the housing and is coaxially mounted with the housing. An annular slide rail is coaxially provided inside the housing. The clamp is slidably connected to the housing through the annular slide rail. Preferably, the annular slide rail is a groove with a trapezoidal or dovetail-shaped cross section. Through the annular slide rail, the clamp can rotate along the axis, thereby realizing the up-and-down flipping of the workpiece or adjusting the tilt angle of the workpiece. In some cases, when it is necessary to process the bottom surface or a certain side of the workpiece, the workpiece can be flipped without the worker manually disassembling or opening the clamp, which greatly improves the processing efficiency.

[0029] Preferably, the housing includes an upper housing 6 and a lower housing 8. The upper housing 6 and the lower housing 8 are rotatably connected by a pin and can be opened and closed with each other. The clamp includes an upper clamp body and a lower clamp body. The upper clamp body and the lower clamp body open and close synchronously with the upper housing 6 and the lower housing 8, dividing the housing and the clamp body into upper and lower parts, which makes it easier to manually open and close the clamping mechanism 25. The upper housing 6, the lower housing 8, the upper clamp body and the lower clamp body are all semi-circular.

[0030] Preferably, the rotating mechanism 24 includes a first power unit 10 and a turntable 26 rotatably connected to the frame 1 via bearings. One side of the turntable 26 is fixedly connected to the lower housing 8 with screws, and the other side of the turntable 26 is coaxially fixedly connected to a driven gear 11 with screws. The output end of the first power unit 10 is fixedly connected to a driving gear 12 with screws. The driven gear 11 meshes with the driving gear 12. When the workpiece needs to be processed after processing one end, the first power unit 10 can realize the automatic rotation of the turntable 26, thereby realizing the automatic rotation of the clamping mechanism 25, so that the two ends of the workpiece are swapped, and the other end of the workpiece is rotated to the processing station. The swapping of the workpiece no longer requires disassembling the tooling, nor does it require the worker to move the workpiece, thus freeing up labor and greatly improving processing efficiency. The first power unit 10 is an electric motor.

[0031] Preferably, an external gear ring 13 is fixedly connected to one side of the clamp body with screws. The external gear ring 13 meshes with a drive gear 14. The drive gear 14 is coaxially connected to a second power device 15 with screws. The second power device 15 is fixedly connected to the turntable 26 with screws. The second power device 15 can drive the clamp body to rotate, realize the automatic up and down flipping of the workpiece and adjust the tilt angle, and improve the processing efficiency. The second power device 15 is a motor.

[0032] Preferably, it also includes a support plate 16 placed between the first pressure rod 2 and the clamping mechanism 25. The frame 1 is screwed to a third lifting device 17, which drives the support plate 16 to rise and fall. The support plate 16 is used to provide support at the processing end of the workpiece and at the bottom of the workpiece to ensure force balance. The third lifting device 17 is a cylinder or a hydraulic cylinder.

[0033] Preferably, a limiting plate 18 is provided on the opposite side of the second pressure rod 3. The limiting plate 18 has a limiting hole aligned with the second pressure rod 3. When the second pressure rod 3 extends, it is inserted into the limiting hole. The second lifting device 5 drives the limiting plate 18 and the second pressure rod 3 to rise and fall synchronously. The limiting plate 18 can ensure the force balance at both ends of the second pressure rod 3 and improve the structural stability. The second pressure rod 3 and the limiting plate 18 are both fixedly connected to the telescopic rod screw of the second lifting device 5.

[0034] Preferably, the upper housing 6 and the lower housing 8 are provided with latches to prevent them from opening. The latches are located on opposite sides of the rotatable connection between the upper housing 6 and the lower housing 8. The latches can prevent the housing from being accidentally opened when the clamping mechanism 25 is under force. The latches can be snap-fit ​​latches or threaded latches with screws. Since the latches are existing products purchased on the market, their specific structure will not be described in detail here or in the figures.

[0035] Preferably, both the upper housing 6 and the lower housing 8 are provided with a locking mechanism 19. The locking mechanism 19 includes a limiting post 20 and a cylinder 21. The lower clamp body and the upper clamp body are provided with fixing holes 22 that match the limiting post 20. The cylinder 21 drives the limiting post 20 to insert into the fixing hole 22 to fix the clamp body to the housing. The locking mechanism 19 can provide a limit for the clamp to prevent the clamp from rotating relative to the housing when it is under force, which would affect the processing. The cylinder 21 is fixedly connected to the housing with screws.

[0036] The specific operation process is divided into three steps: fixing the workpiece, swapping the two ends of the workpiece, and flipping the workpiece. Figure 3 and Figure 4 As shown, when fixing the workpiece, firstly, the locking mechanism 19 on the upper housing 6 and the lower housing 8 is activated, causing the limiting post 20 to insert into its respective fixing hole 22, thereby fixing the upper clamp body to the upper housing 6 and the lower clamp body to the lower housing 8. Then, the housing and clamp are opened, and the bridge housing workpiece is placed into the clamp. The clamp and housing are closed and locked with a lock. The locking mechanism 19 is closed, the limiting post 20 leaves the fixing hole 22, and the sliding between the clamp and the housing is restored. The first lifting device 4, the second lifting device 5, and the third lifting device 17 rise. When the first pressure rod 2, the second pressure rod 3, and the support plate 16 reach the specified height, the rising stops. Then, the first pressure rod 2 and the second pressure rod 3 extend, applying pressure to both ends of the bridge housing for fixing. The second pressure rod 3 is inserted into the limiting hole to begin processing one end of the bridge housing. After this end is processed, the two ends of the workpiece need to be swapped. Figure 5 and Figure 6As shown, when the two ends of the workpiece are swapped, the first pressure rod 2 and the second pressure rod 3 retract, and the first lifting device 4, the second lifting device 5, and the third lifting device 17 descend, thus making room for the workpiece to rotate. Then, the first power device 10 drives the turntable 26 to rotate, causing the clamp and the workpiece on it to rotate horizontally by 180 degrees, realizing the swapping of the two ends of the workpiece. Then, the above clamping operation is repeated to clamp and fix the two ends of the workpiece again, so as to process the other end of the workpiece. When it is necessary to process the bottom surface of the workpiece, the workpiece needs to be flipped up and down. When the workpiece is flipped, the first pressure rod 2 and the second pressure rod 3 retract, and the third lifting device 17 descends, thus making room for the workpiece to flip. After the workpiece is flipped 180 degrees, the height of the first lifting device 4, the second lifting device 5, and the third lifting device 17 is readjusted according to the height of the top surface of the workpiece at this time. Then, the first pressure rod 2 and the second pressure rod 3 are extended to clamp and fix the workpiece again for processing.

[0037] This utility model discloses a placement fixture for bridge housing processing. The workpiece on the clamping mechanism 25 can rotate with the clamping mechanism 25, enabling the swapping of the two ends of the workpiece without disassembling the fixture or moving the workpiece, thus improving processing efficiency. The first pressure rod 2 and the second pressure rod 3 can press down on both ends of the workpiece, ensuring the stability of both ends of the workpiece during processing. The first pressure rod 2 and the second pressure rod 3 themselves have a telescopic function. Driven by the first lifting device 4 and the second lifting device 5, when the first pressure rod 2 and the second pressure rod 3 first rise and then extend, they contact the ends of the workpiece and provide a pressing function. When the first pressure rod 2 and the second pressure rod 3 first retract and then descend, they move away from the workpiece, thereby making room for the workpiece to rotate, which facilitates the rotation mechanism 24 to drive the clamping mechanism 25 to rotate. The fixation of the workpiece by the first pressure rod 2 and the second pressure rod 3 is automatic lifting and telescopic, without the need for manual disassembly, further improving processing efficiency. Compared with traditional technology, this technical solution avoids the tedious process of disassembling various components and also avoids the operation of workers moving the bridge housing, thus improving the processing efficiency of the bridge housing.

All equivalent changes and modifications made in accordance with the scope of the claims of this utility model should fall within the technical scope of this utility model.
