Description

Technical Field

[0001] The utility model belongs to the technical field of cooling water jacket processing, in particular to a new type of cooling water jacket processing fixture. Background Art

[0002] As the main cooling component of the electric motor in electric vehicles, the cooling water jacket plays a vital role in the performance of the motor.

[0003] When processing the cooling water jacket, it is necessary to use a clamp to clamp it. The traditional clamp is generally used to clamp the outside of the cooling water jacket. However, the cooling water jacket is designed to be cylindrical and hollow inside. When clamping it with a traditional clamp, it is easy to squeeze and deform it, thereby affecting the product quality. Utility Model Content

[0004] In order to overcome the above defects, the utility model provides a novel clamp for machining cooling water jackets, which solves the problem that the cooling water jackets are easily squeezed and deformed when clamped by traditional clamps, thereby affecting product quality.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of cooling water jacket processing fixture, including a workbench, a fixed column fixedly connected to the bottom of the workbench, three clamps slidably connected to the top of the workbench, a connecting rod fixedly connected to the bottom of the clamp, a worm gear rotatably connected to the bottom of the fixed column, a worm gear meshed with the worm gear, a turntable fixedly connected to the top of the worm gear, three sliding grooves on the turntable, and a round cap fixedly connected to one end of the connecting rod.

[0006] As a further solution of the utility model: a plastic pad is arranged on the clamping plate, and four columns are fixedly connected to the bottom of the workbench.

[0007] As a further solution of the utility model: one end of the column away from the workbench is fixedly connected with a foot pad, and one end of the worm is provided with a handle.

[0008] As a further solution of the utility model: two bearings are arranged on the worm, and a limiting hole is opened on the worm.

[0009] As a further solution of the utility model: a sleeve is arranged on the worm, and a limit rod is slidably connected to the sleeve.

[0010] As a further solution of the utility model: a spring is sleeved on the limit rod, and one end of the limit rod is fixedly connected to a circular plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The new cooling water jacket processing fixture is provided with a worm wheel, a clamping plate, a worm, a connecting rod and a slide groove, and the cooling water jacket is arranged outside the three clamping plates. The handle is turned to drive the worm, the worm wheel and the turntable to rotate. The three connecting rods and the clamping plate are kept away from the center of the turntable by the limiting effect of the slide groove. The clamping plate presses the inner wall of the cooling water jacket to fix the cooling water jacket. The inner wall of the cooling water jacket is pressed by the three clamping plates to avoid being squeezed and deformed by clamping from the outside of the cooling water jacket, thereby improving product quality.

[0013] 2. The new cooling water jacket processing fixture is provided with a limit hole, a worm gear, a sleeve, a handle, a spring and a limit rod. When the handle needs to be removed, the circular plate is pulled to drive the limit rod to move upward, so that the limit rod is disengaged from the limit hole, and the handle can be removed from the worm gear. When installing the handle, the circular plate is pulled to move the limit rod upward, the sleeve is put on the worm gear, the circular plate is loosened, the circular plate and the limit rod are pulled downward by the spring, and the limit rod is inserted into the limit hole to complete the installation of the handle. When processing the cooling water jacket, the handle is removed to avoid the cooling water jacket loosening due to accidental touching of the handle by personnel during processing, thereby improving the clamping stability.

DETAILED DESCRIPTION

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-4As shown, the utility model provides a technical solution: a new type of cooling water jacket processing fixture, including a workbench 1, a fixed column 6 is fixedly connected to the bottom of the workbench 1, and three clamps 2 are slidably connected to the top of the workbench 1. Because the clamps 2 are designed with curved surfaces, they can fit the inner wall of the cooling water jacket to improve the clamping stability. Plastic pads 3 are arranged on the clamps 2. Because the plastic pads 3 are arranged, the plastic pads 3 prevent the clamps 2 from directly contacting the inner wall of the cooling water jacket, thereby reducing the wear of the clamps 2 on the cooling water jacket. Four columns 4 are fixedly connected to the bottom of the workbench 1.

[0021] A connecting rod 12 is fixedly connected to the bottom of the splint 2, and a worm wheel 9 is rotatably connected to the bottom of the fixed column 6. A worm 10 is meshed on the worm wheel 9, and two bearings 11 are provided on the worm 10. Due to the bearings 11, when the handle 7 is turned, the worm 10 rotates on the bearings 11, which reduces friction and makes it easier to turn the handle 7. A limiting hole 14 is provided on the worm 10.

[0022] The top of the worm wheel 9 is fixedly connected with a turntable 8, on which three slide slots 13 are provided. A round cap 19 is fixedly connected to one end of the connecting rod 12. A spring 15 is sleeved on the limiting rod 17, and a round plate 18 is fixedly connected to one end of the limiting rod 17.

[0023] One end of the column 4 away from the workbench 1 is fixedly connected to a foot pad 5, and a handle 7 is provided at one end of the worm 10. The handle 7 makes the worm 10 easier to rotate, thereby improving the convenience of operation. A sleeve 16 is provided on the worm 10, and a limit rod 17 is slidably connected to the sleeve 16.

[0024] The working principle of the utility model is:

[0025] The cooling water jacket is placed outside the three clamping plates 2, and the handle 7 is turned to drive the worm 10, the worm wheel 9 and the turntable 8 to rotate. The three connecting rods 12 and the clamping plates 2 are kept away from the center of the turntable 8 by the limiting effect of the slide groove 13, and the clamping plates 2 press the inner wall of the cooling water jacket to fix the cooling water jacket;

[0026] When the handle 7 needs to be disassembled, the circular plate 18 is pulled to drive the limiting rod 17 to move upward, so that the limiting rod 17 is disengaged from the limiting hole 14, and the handle 7 can be removed from the worm 10. When installing the handle 7, the circular plate 18 is pulled to move the limiting rod 17 upward, the sleeve 16 is put on the worm 10, the circular plate 18 is loosened, the spring 15 pulls the circular plate 18 and the limiting rod 17 downward, and the limiting rod 17 is inserted into the limiting hole 14 to complete the installation of the handle 7.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0028] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
