Description

Technical Field

[0001] This utility model relates to the field of machining fixture technology, and in particular to a clamping device for machining gearbox housings. Background Technology

[0002] The gearbox housing needs to be fixed during processing to facilitate drilling and grooving. Since there are many types of gearboxes with different shapes and sizes, there are also many fixtures involved in fixing the gearboxes.

[0003] Traditional fixtures typically consist of a base and a locking cylinder and a limiting block mounted on the base. The locking cylinder is used to lock and fix the gearbox housing, while the limiting block is responsible for supporting and limiting the gearbox. During manufacturing, this type of fixture requires pre-cut slots and holes in the base according to the size and shape of the target gearbox housing to facilitate the installation of the locking cylinder and limiting block, ensuring that the locking cylinder and limiting block can adapt to the size and shape of the target gearbox. However, once a different gearbox housing is used, this fixture is no longer applicable, and another compatible fixture needs to be selected. Traditional fixtures have a limited range of applications and are relatively cumbersome to disassemble and assemble, which significantly affects the processing efficiency of the gearbox housing.

[0004] Therefore, it is necessary to propose a clamping device for machining gearbox housings in order to improve the machining efficiency of gearbox housings. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that existing gearbox housing clamps have a limited range of applications and are cumbersome to disassemble and assemble, resulting in low processing efficiency of gearbox housings. A clamping device for processing gearbox housings is provided.

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

[0007] A clamping device for machining a gearbox housing includes a base with a sliding groove and a telescopic rod inside the sliding groove. The bottom surface of the base has a serrated groove that is not parallel to the sliding groove. A fixed seat is provided at the bottom of the base, and a support seat is provided at the top of the base. The support seat has a locking device and a limiting device. The side of the fixed seat opposite to the base has a serrated protrusion that matches the serrated groove. The two ends of the telescopic rod are fixedly connected to the support seat and the fixed seat, respectively. When the telescopic rod retracts, it causes the fixed seat to fit against the bottom surface of the base, thereby causing the serrated protrusion to insert into the serrated groove.

[0008] Furthermore, a slider is fixedly connected to the outside of the telescopic rod. The slider is slidably connected to the sliding groove. The slider can fix the telescopic rod in the sliding groove, allowing the telescopic rod to slide along the sliding groove, which facilitates the position adjustment of the locking device and the limiting device.

[0009] Furthermore, the telescopic pole is equipped with a telescopic cylinder, which drives the telescopic pole to extend and retract. The telescopic cylinder can drive the telescopic pole to extend and retract, and its placement inside the telescopic pole can effectively save floor space.

[0010] Furthermore, a limiting slide rod is connected between the fixed seat and the support seat. The limiting slide rod is parallel to the telescopic rod and slidably connected to the sliding groove. The limiting slide rod can extend and retract synchronously with the telescopic rod. The function of the limiting slide rod is to improve the structural stability between the fixed seat and the support seat and to improve the stability of the fixed seat and the support seat moving along the sliding groove.

[0011] Furthermore, it also includes a steering seat, the support seat having a steering hole that is rotatably connected to the steering seat, the steering seat being located at the bottom of the locking device and the bottom of the limiting device, the steering seat being able to rotate within the steering hole, thereby adjusting the angle of the locking device to adapt to gearbox housings of different shapes and sizes.

[0012] Furthermore, the steering seat and the support seat are fixed by screws. When the screws are tightened, the steering seat can be fixed to the support seat and stop rotating. After the screws are unscrewed, the steering seat resumes its rotation function and can rotate within the steering hole to adjust the angle of the locking device.

[0013] Furthermore, the screws are evenly distributed in a ring around the axis of the steering seat, with at least two screws, preferably three, so that the multiple screws can ensure the fixing effect between the screws and the support seat.

[0014] Furthermore, the telescopic cylinder is a telescopic air cylinder, which has a fast start-up and a simple structure.

[0015] Furthermore, multiple sliding grooves are provided and distributed in different directions on the base. Depending on the shape of the gearbox housing, sliding grooves with different extension shapes are involved. When the gearbox housing has the same shape but different sizes, the positions of the locking device and the limiting device can be adjusted through the sliding grooves so that they can be adapted to clamp the gearbox housing, thereby improving the applicability of the clamp.

[0016] This utility model discloses a clamping device for processing gearbox housings. The locking device and limiting device are located on a support base and can move within a sliding groove via a telescopic rod, thereby adjusting the positions of the locking and limiting devices to accommodate gearbox housings of different sizes and shapes, thus improving the applicability of the clamp. The serrated groove on the base is not parallel to the direction of the sliding groove, while the serrated protrusion on the fixed base engages with the serrated groove. When the serrated groove and serrated protrusion interlock, they limit the position of the fixed base, preventing the telescopic rod from moving within the sliding groove. Furthermore, the extension and retraction of the telescopic rod clamps both the fixed base and the support base to the base, thus securing all three and preventing wobbling. The entire adjustment process requires no screw removal. Compared to traditional technologies, this solution achieves position adjustment and fixation of the locking and limiting devices solely through the extension and retraction of the telescopic rod, effectively improving the processing efficiency of gearbox housings.

[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 4 As shown, this embodiment provides a clamping device for machining a gearbox housing, including a base 1. The base 1 has sliding grooves 2, which extend from one edge of the base 1 towards the center. There can be six, eight, or four sliding grooves 2, preferably eight. The specific extension shape of the sliding grooves 2 is adapted to the shape of the gearbox housing. A telescopic rod 3 is provided within the sliding grooves 2. A serrated groove 4, not parallel to the sliding groove 2, is provided on the bottom surface of the base 1. A fixing seat 5 is provided at the bottom of the base 1, and a support seat 6 is provided at the top of the base 1. The support seat 6 has a locking device 7 and a limiting device 8. The locking device 7 and the limiting device 8 can be on the same support seat 6, or installed on different support seats 6, or even in different sliding grooves 2. Figure 6 The fixing base 5 has a serrated protrusion 9 on the side opposite to the base 1, which matches the serrated groove 4. The serrated groove 4 can be located on the top or bottom surface of the base 1, or it can be provided on both sides. Figure 5 The serrated protrusion 9 can also be on the support base 6, or simultaneously on the fixed base 5 and the support base 6. The two ends of the telescopic rod 3 are respectively fixedly connected to the support base 6 and the fixed base 5 with screws. When the telescopic rod 3 retracts, it drives the fixed base 5 to fit against the bottom surface of the base 1, thereby causing the serrated protrusion 9 to be inserted into the serrated groove 4.

[0028] Preferred, such as Figure 2 As shown, a slider 10 is fixedly connected to the outer side of the telescopic rod 3 by screws. The slider 10 is slidably connected to the sliding groove 2 via a guide rail. The slider 10 can fix and limit the telescopic rod 3 within the sliding groove 2, allowing the telescopic rod 3 to slide along the sliding groove 2. This facilitates the position adjustment of the locking device 7 and the limiting device 8. Preferably, as shown... Figure 3 A telescopic cylinder 11 is fixedly installed inside the telescopic rod 3 using screws. The telescopic cylinder 11 drives the telescopic rod 3 to extend and retract. The telescopic cylinder 11 can drive the telescopic rod 3 to extend and retract, and its placement inside the telescopic rod 3 can effectively save floor space. Preferably, a limiting slide rod 12 is fixedly connected between the fixed seat 5 and the support seat 6 using screws. The limiting slide rod 12 is parallel to the telescopic rod 3 and is slidably connected to the sliding groove 2. The limiting slide rod 12 can extend and retract synchronously with the telescopic rod 3. The function of the limiting slide rod 12 is to improve the structural stability between the fixed seat 5 and the support seat 6 and to improve the stability of the fixed seat 5 and the support seat 6 as they move along the sliding groove 2.

[0029] Preferably, it also includes a steering seat 13. The support seat 6 has a steering hole 14 that is rotatably connected to the steering seat 13 via a bearing. The steering seat 13 is located at the bottom of the locking device 7 and the bottom of the limiting device 8. The steering seat 13 can rotate within the steering hole 14, thereby adjusting the angle of the locking device 7 to adapt to gearbox housings of different shapes and sizes. Preferably, the steering seat 13 and the support seat 6 are fixed by screws 15. When the screws 15 are tightened, the steering seat 13 can be fixed to the support seat 6 and stop rotating. After the screws 15 are rotated down, the steering seat 13 returns to its rotational function and can rotate within the steering hole 14 to adjust the angle of the locking device 7. Preferably, the screws 15 are evenly distributed in a ring around the axis of the steering seat 13. There are at least two screws 15, preferably three. Multiple screws 15 can ensure the fixing effect between the screws 15 and the support seat 6. Preferably, the telescopic cylinder 11 is a telescopic cylinder. Telescopic cylinders start quickly and have a simple structure. Preferably, such as Figure 7 Multiple sliding grooves 2 are provided and distributed in different directions on the base 1. Depending on the shape of the gearbox housing, sliding grooves 2 with different extension shapes are involved. When the gearbox housing has the same shape but different size, the position of the locking device 7 and the limiting device 8 can be adjusted by sliding grooves 2 so that the two can be adapted to clamp the gearbox housing, thereby improving the applicability of the clamp.

[0030] In use, the locking device 7 and the limiting device 8 are on the support base 6 and can move within the sliding groove 2 via the telescopic rod 3, thereby adjusting the position of the locking device 7 and the limiting device 8 to adapt to gearbox housings of different sizes and shapes, thus improving the applicability of the fixture. The serrated groove 4 on the base 1 is not parallel to the direction of the sliding groove 2, and the serrated protrusion 9 on the fixed base 5 cooperates with the serrated groove 4. When the serrated groove 4 and the serrated protrusion 9 are interlocked, they can limit the fixed base 5, preventing the telescopic rod 3 from moving within the sliding groove 2. Furthermore, the extension and retraction of the telescopic rod 3 will clamp the fixed base 5 and the support base 6 with the base 1, thereby fixing all three and preventing shaking. The entire adjustment process does not require the removal of screws. Screw 15 is only adjusted when adjusting the angle of the locking device 7 and the limiting device 8, thus greatly improving the efficiency of disassembly and assembly. Compared with traditional technology, this technical solution can achieve the position adjustment and fixation of the locking device 7 and the limiting device 8 simply by extending and retracting the telescopic rod 3, effectively improving the processing efficiency of the gearbox housing.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. 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.
