However, this device still has the following problems in use:

[0004] During assembly, the pump bracket hole needs to be aligned with the tie rod and inserted. The bracket is then pressed in using the user's weight. A torque wrench is then used to tighten the tie rod nut to the specified torque. This process can lead to an unbalanced bracket placement and product positioning errors. The assembly accuracy is difficult to meet design requirements, thus affecting the stability of the pump's operation.

[0005] Based on this, the present invention designs a water pump assembly bracket clamping fixture to solve the above problems. Summary of the Invention

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a water pump assembly bracket clamping fixture.

[0007] To achieve the above objectives, a pump assembly bracket clamping fixture is designed, including a base plate, a support frame, an adjustable pump bracket mounting system, an automatic clamping mechanism, and a mounting frame. The support frame is fixedly mounted on the upper end of the base plate. An adjustable pump bracket mounting system, adaptable to different sized pump brackets and pump bodies for assembly, is mounted on the upper end of the support frame. The adjustable pump bracket mounting system includes a cylinder, a pressure plate, a control component for controlling the movement of the cylinder, and a limit rod. The control component is mounted on the support frame, the cylinder is mounted on the control component, and the output end of the cylinder is fixedly connected to the pressure plate. The limit rods are symmetrically fixedly mounted on the upper end of the pressure plate and connected to the control component. A mounting frame is fixedly mounted on the upper front side of the base plate. An automatic clamping mechanism for automatically pre-clamping and securing the pump body is mounted on the mounting frame.

[0008] Furthermore, the automatic clamping mechanism includes a clamping block, a clamping spring, a push rod, a rotating rod, and a clamping plate. The lower end of the clamping block is fixedly connected to the upper end of the clamping spring; the lower end of the clamping spring is fixedly installed on the upper end of the base plate; both the left and right ends of the clamping block are hinged to one end of a push rod; the other end of the push rod is hinged to the lower end of the rotating rod; the left and right ends of the mounting frame are symmetrically provided with clearance grooves; the rotating rod is set in the clearance groove, and the middle part of the rotating rod is hinged to the mounting frame; a clamping plate is hinged to the close ends of the two rotating rods.

[0009] Furthermore, a sliding groove is provided at the upper middle part of the mounting bracket, and the clamping block is slidably connected to the sliding groove for limiting.

[0010] Furthermore, the contact surfaces between the two clamping plates and the water pump body are set in an arc shape.

[0011] Furthermore, both of the rotating rods are in an outward-extended state under normal conditions.

[0012] Furthermore, the control assembly includes a control drive assembly, a first guide rod, and a movable plate. A movable groove is provided on the upper front side of the support frame, and the left and right ends of the first guide rod are fixedly connected to the left and right ends of the movable groove.

[0014] Furthermore, a rubber anti-slip pad is provided at the lower end of the pressure plate.

[0015] Compared with the prior art, this utility model places the water pump body on the upper end of the mounting bracket, and then the automatic clamping mechanism fixes the water pump body, keeping it fixed in the vertical direction. This avoids the impact of water pump body shaking on the installation of the water pump bracket, improves the practicality of the device, and eliminates the need for an additional positioning mechanism, reducing the workload of the operator in positioning the water pump body. After the water pump body is fixed, the operator places the water pump bracket on top of the water pump body. Then, the control component drives the cylinder to move above the water pump body. The cylinder drives the pressure plate to move downward with the limit rod, so that the pressure plate contacts the water pump bracket. Under the set pressure, the cylinder presses the water pump bracket tightly onto the water pump body. Then, the operator fixes the water pump bracket to the water pump body by changing the torque wrench. Then, the cylinder drives the pressure plate to reset, and the drive component drives the clamping movable component to reset, releasing the lock on the water pump body. By applying uniform pressure to the water pump bracket by the cylinder, the water pump bracket and the water pump body are accurately positioned in one step, preventing the bracket from shifting and ensuring the accuracy of assembly.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0023] In some embodiments, please refer to the accompanying drawings. Figures 1 to 5A water pump assembly bracket clamping fixture includes a base plate 1, a support frame 2, an adjustable water pump bracket mounting 3, an automatic clamping mechanism 4, and a mounting frame 5. The support frame 2 is fixedly mounted on the upper end of the base plate 1. An adjustable water pump bracket mounting 3, which is adapted to assemble water pump brackets of different sizes with the water pump body, is mounted on the upper end of the support frame 2. The adjustable water pump bracket mounting 3 includes a cylinder 31, a pressure plate 32, a control component 33 for controlling the movement of the cylinder 31, and a limit rod 34. The control component 33 is mounted on the support frame 2, the cylinder 31 is mounted on the control component 33, and the output end of the cylinder 31 is fixedly connected to the pressure plate 32. The limit rods 34 are symmetrically fixedly mounted on the upper end of the pressure plate 32 and are connected to the control component 33. A rubber anti-slip pad is provided at the lower end of the pressure plate 32.

[0024] A mounting bracket 5 is fixedly installed on the upper front side of the base plate 1; an automatic clamping mechanism 4 for automatically pre-clamping and securing the water pump body is installed on the mounting bracket 5.

[0025] In this invention, the water pump body is placed on the upper end of the mounting bracket 5, and then the automatic clamping mechanism 4 fixes the water pump body, keeping it vertically fixed. This prevents the water pump body from shaking and affecting the installation of the water pump bracket, improving the practicality of the device. Furthermore, it eliminates the need for an additional positioning mechanism, reducing the operator's workload in positioning the water pump body. After the water pump body is fixed, the operator places the water pump bracket on top of the water pump body, and then the control component 33 drives the cylinder 31 to move to the upper part of the water pump body. When cylinder 31 operates, it drives pressure plate 32 to move downwards along with limit rod 34, so that pressure plate 32 contacts water pump bracket. Under the set pressure, cylinder 31 presses water pump bracket tightly onto water pump body. Then, the operator fixes water pump bracket to water pump body by changing torque wrench. Afterwards, cylinder 31 operates to drive pressure plate 32 to reset, and automatic clamping mechanism 4 releases the lock on water pump body. By applying uniform pressure to water pump bracket by cylinder 31, accurate positioning of water pump bracket and water pump body is completed, preventing bracket position deviation and ensuring assembly accuracy.

[0026] The automatic clamping mechanism 4 includes a clamping block 42, a clamping spring 43, a push rod 44, a rotating rod 45, and a clamping plate 46. A sliding groove 41 is provided in the middle of the upper end of the mounting frame 5, and the clamping block 42 is slidably connected to the sliding groove 41. The lower end of the clamping block 42 is fixedly connected to the upper end of the clamping spring 43. The lower end of the clamping spring 43 is fixedly installed on the upper end of the base plate 1. Both ends of the clamping block 42 are hinged to one end of a push rod 44. The other end of the push rod 44 is hinged to the lower end of the rotating rod 45. The mounting frame 5 has symmetrical clearance grooves 47 on both the left and right ends. The rotating rod 45 is located within the clearance groove 47, and its middle part is hinged to the mounting frame 5. A clamping plate 46 is hinged to one end of each of the two rotating rods 45 that is close to each other. The contact surfaces of the two clamping plates 46 with the pump body are arc-shaped to increase the contact area with the pump body. Both rotating rods 45 are in an outwardly extended state under normal conditions.

[0027] In this utility model, when the water pump body is placed on the mounting bracket 5, the water pump body will press down on the clamping block 42. The clamping block 42 moves down along the sliding groove 41 and compresses the clamping spring 43, so that the two push rods 44 push the rotating rod 45 in opposite directions at the same time, so that the two rotating rods 45 drive the clamping plate 46 to hug the water pump body from the left and right sides at the same time in the direction of approaching each other.

[0028] The control component 33 includes a first servo motor 331, a first lead screw 332, a first guide rod 334, and a moving plate 335. A moving groove 333 is provided on the upper front side of the support frame 2. The left and right ends of the first lead screw 332 are rotatably connected to the left and right ends of the moving groove 333, and the left and right ends of the first guide rod 334 are fixedly connected to the left and right ends of the moving groove 333. The first servo motor 331 is fixedly installed on the right end of the support frame 2 by a bracket, and the output end of the first servo motor 331 is fixedly connected to the right end of the first lead screw 332. The moving plate 335 is threadedly connected to the first lead screw 332. The moving plate 335 is slidably connected to the first guide rod 334. The cylinder 31 is fixedly installed on the upper end of the moving plate 335, and the limiting rod 34 is slidably connected to the moving plate 335.

[0029] In this utility model, since the installation positions of water pump bodies of different sizes on the mounting bracket 5 are different, after the water pump body is fixed, the first servo motor 331 drives the first lead screw 332 to rotate, so that the moving plate 335 moves along the first guide rod 334 and the moving groove 333. The moving plate 335 drives the cylinder 31 to move together until the pressure plate 32 is aligned with the upper end of the water pump body.
