Technical Field

[0001] The present application relates to the technical field of fixing devices for machining, and more particularly to a fixing tool for machining a gearbox. Background Art

[0002] An air motor gearbox is a housing for mounting a gear set. Usually, when manufacturing a gearbox, it is necessary to machine the shape of the outer wall of the gearbox according to the requirements for mounting the air motor gearbox. In order to better mount the gear set and make the installation of the gear set more stable, it is necessary to open positioning grooves with high precision on the inner wall of the gearbox.

[0003] Currently, in the process of machining a gearbox, first, the part to be machined is fixed on a machining jig. Threaded holes and clamping holes for fixing are provided on the side wall of the part. The jig is fixed on a machine tool. The jig usually selects clamping jaws. Under the clamping and fixing of the jig, the fixing of the part to be machined is more stable. Subsequently, the staff processes the part through tools such as milling cutters, and finally realizes the machining of the gearbox.

[0004] The above method of clamping and fixing the part by clamping jaws can only clamp and fix the part in the middle position of the jig, which causes inconvenience in machining different positions of the part and there is room for improvement. Summary of the Utility Model

[0005] In order to facilitate the machining of different positions of the part, the present application provides a fixing tool for machining a gearbox.

[0006] A fixing tool for machining a gearbox provided by the present application adopts the following technical solution:

[0007] A fixing tool for machining a gearbox includes a bearing seat and a fixing rod. The fixing rod is fixed to the side wall of the bearing seat. The fixing rod is fixed to the side wall of the part. A clamping block is slidably connected to the side wall of the bearing seat. The side wall of the clamping block abuts against the side wall of the part. The fixing rod and the clamping block cooperate to clamp the part. A locking member is provided on the side wall of the clamping block.

[0008] By adopting the above technical solution, the staff fixes the part to the side wall of the bearing seat through the fixing rod. The setting of the fixing rod facilitates the installation of the part. Subsequently, the staff manipulates the clamping block to slide towards the direction of the fixing rod. The side wall of the part abuts against the side wall of the clamping block. The clamping block and the fixing rod cooperate to clamp the part. After the staff rotates the part, the part is installed on the side wall of the bearing seat. Subsequently, the clamping block is locked through the locking member. At this time, the clamping block and the fixing rod cooperate to clamp the part again. This setting reduces the possibility of the clamping block sliding, enables the part to be stably fixed on the side wall of the bearing seat, and facilitates the machining of different positions of the part.

[0009] Optionally, an installation groove is formed in the side wall of the clamping block, a driving rod is rotatably connected to the side wall of the clamping block, a sliding block is threadedly connected to the side wall of the driving rod, the sliding block is located inside the installation groove, a wedge block is fixed to the side wall of the bearing seat, and the sliding block abuts against the side wall of the wedge block.

[0010] By adopting the above technical solution, this setting enables the clamping block to slide smoothly and effectively clamp and fix the part through the threaded connection between the driving rod and the sliding block and the action of the wedge block, improving the fixing accuracy and stability of the part.

[0011] Optionally, the locking member includes a locking block and a locking rod, the locking rod is threadedly connected to the side wall of the locking block, the locking rod is threadedly connected to the bearing seat, and the side wall of the locking block abuts against the side wall of the clamping block.

[0012] By adopting the above technical solution, when the side wall of the clamping block abuts against the side wall of the part, the worker locks the locking block through the locking rod, and under the action of the locking block, the clamping block is fixed to the side wall of the bearing seat, thereby realizing the stable locking of the clamping block and ensuring the fixing stability of the part during the processing.

[0013] Optionally, a guiding groove is formed in the side wall of the clamping block, and the side wall of the locking block is slidably connected to the inner wall of the guiding groove.

[0014] By adopting the above technical solution, the setting of the guiding groove enables the locking block to slide smoothly along the guiding groove, improving the stability of the clamping block and ensuring more reliable fixing of the part during the processing.

[0015] Optionally, guiding grooves are formed on both sides of the clamping block, and the locking blocks are slidably connected to the inner walls of the guiding grooves.

[0016] By adopting the above technical solution, this setting restricts the sliding direction of the clamping block on the side wall of the bearing seat, making the clamping process of the clamping block on the part more stable and enhancing the clamping effect of the fixing tool on the part.

[0017] Optionally, clamping blocks are fixed to both sides of the bearing seat, and the clamping blocks are both located on the side of the bearing seat close to the fixed rod.

[0018] By adopting the above technical solution, the two clamping blocks jointly clamp the part, making the fixing of the part on the side wall of the bearing seat more reliable and effectively restricting the rotation process of the part on the side wall of the bearing seat.

[0019] Optionally, a plurality of positioning holes are formed in the side of the bearing seat close to the fixed rod, and the fixed rod is threadedly connected to the inner wall of the positioning hole.

[0020] By adopting the above technical solution, before machining the part, the staff adjusts the position of the fixing rod on the side wall of the bearing seat through the positioning hole, so that the installation position of the part is changed, and then the installation position of the part on the side wall of the bearing seat is changed. This setting facilitates the staff to better fix the part on the side wall of the bearing seat.

[0021] Optionally, a plurality of fixing grooves are formed in the side wall of the bearing seat, and the fixing grooves are away from the fixing rod.

[0022] By adopting the above technical solution, the formation of the fixing grooves facilitates the staff to fix the bearing seat, thereby improving the stability of the bearing seat when clamping the part, and further making the machining process of the part more stable.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The part is fixed to the side wall of the bearing seat through the fixing rod. Under the clamping action of the clamping block, the possibility of the part rotating on the side wall of the bearing seat is reduced, and the installation angle of the part is changed. The clamping block and the fixing rod cooperate to clamp the part. This setting facilitates the machining of different positions of the part;

[0025] 2. The setting of the locking block and the guiding groove limits the sliding track of the clamping block on the side wall of the bearing seat, making the working process of the clamping block more stable and facilitating the staff to machine the part. Description of the Drawings

Detailed Embodiment

[0031] The following will Figures 1-4 be further described in detail with reference to the

[0032] The embodiment of the present application discloses a fixing tooling for gearbox machining.

[0033] Refer to Figure 1 Figure 1 , a fixing tooling for gearbox processing, includes a bearing seat 1 and a fixing rod 2. A fixing nut 12 is threadedly connected to the side wall of the fixing rod 2. The fixing rod 2 is fixed to the side wall of the bearing seat 1. Before processing a part, the staff fixes the part to the side wall of the fixing rod 2 through threads, and then the staff tightens the fixing nut 12. At this time, the part is fixed to the side wall of the bearing seat 1.

[0034] Refer to Figure 1 Figure 1 , a fixing groove 11 is provided on the side wall of the bearing seat 1. Before the clamping tooling clamps the part, the staff fixes the bearing seat 1 to the processing environment through the fixing groove 11. In the embodiment of the present application, the bearing seat 1 is preferably fixed in a frame. A fixing rod 2 is installed on the side wall of the frame, and the side wall of the fixing rod 2 abuts against the inner wall of the fixing groove 11, which increases the stability of the bearing seat 1 during operation and facilitates the subsequent clamping work. A plurality of positioning holes 10 are provided on the side wall of the bearing seat 1. Before processing the part, the staff removes the fixing rod 2, and then installs and fixes the fixing rod 2 to the inner wall of the positioning hole 10 through threads. This setting increases the installation position of the part on the side wall of the bearing seat 1.

[0035] Refer to Figure 2 Figure 2 , clamping blocks 3 are slidably connected to both sides of the side of the bearing seat 1 close to the fixing rod 2. A locking member 4 is provided on the side wall of the clamping block 3. The side wall of the part abuts against the inner wall of the clamping block 3. When clamping the part, the staff controls the clamping block 3 to slide towards the fixing rod 2. When the clamping block 3 abuts against the part, the staff locks the locking member 4, which reduces the possibility of the clamping block 3 sliding on the side wall of the bearing seat 1 and increases the stability of the clamping tooling when clamping the part.

[0036] Refer to Figure 2 Figure 2 , the locking member 4 includes a locking block 41 and a locking rod 42. The locking rod 42 is threadedly connected to the side wall of the locking block 41. Guide grooves 9 are provided on both sides of the clamping block 3. In the embodiment of the present application, preferably four locking blocks 41 are provided, and the side wall of the locking block 41 abuts against the inner wall of the guide groove 9. When locking the clamping block 3, the staff locks the locking block 41 through the locking rod 42. At this time, the clamping block 3 is fixed on the side wall of the bearing seat 1. The setting of the guide groove 9 limits the sliding track of the clamping block 3 on the side wall of the bearing seat 1, facilitates the clamping process of the clamping block 3, and increases the clamping stability of the clamping tooling.

[0037] Refer to Figure 3 And Figure 4, an installation groove 5 is formed on the side wall of the clamping block 3, a driving rod 6 is threadedly connected to the side wall of the clamping block 3, a sliding block 7 is threadedly connected to the side wall of the driving rod 6, a wedge-shaped block 8 is fixed to the side wall of the bearing seat 1, the side wall of the sliding block 7 abuts against the side wall of the wedge-shaped block 8, and both the sliding block 7 and the wedge-shaped block 8 are close to the inner wall of the installation groove 5. When clamping a part, the worker manipulates the driving rod 6 to rotate. At this time, the sliding block 7 slides on the side wall of the wedge-shaped block 8, the sliding block 7 drives the driving rod 6 to slide, and then the clamping block 3 slides on the side wall of the bearing seat 1.

[0038] The implementation principle of a fixing tooling for gearbox processing in an embodiment of the present application is as follows: When using the clamping tooling to clamp a part, the worker fixes the part to the side wall of the bearing seat 1 through the fixing rod 2, and then tightens the fixing nut 12. At this time, the side wall of the part abuts against the side wall of the bearing seat 1. The worker manipulates the driving rod 6 to rotate on the side wall of the clamping block 3. The rotation of the driving rod 6 drives the clamping block 3 to slide towards the direction of the fixing rod 2. Subsequently, the side wall of the part abuts against the inner wall of the clamping block 3. At this time, the worker tightens the locking rod 42, and the side wall of the locking block 41 abuts against the inner wall of the guiding groove 9. When the worker processes different parts of the part, the position of the part on the side wall of the bearing seat 1 is changed, the fixing nut 12 is tightened, and then the above operations are repeated. This setting facilitates the processing of different positions of the part.

[0039] The above are all the preferred embodiments of the present application.
