Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and more specifically, to a clamp. Background Technology

[0002] An electromagnetic pressure reducing valve is a pressure reducing valve controlled by electromagnetic effect. Its function is equivalent to a combination of a regular pressure reducing valve and a solenoid valve. It reduces and adjusts the hydraulic system pressure by controlling the system pressure, thereby protecting the hydraulic system from damage by high pressure and improving the working efficiency and stability of the hydraulic pump. Assembly fixtures are required during the assembly process of the electromagnetic pressure reducing valve to improve assembly efficiency.

[0003] Existing electromagnetic pressure reducing valve assembly fixtures typically use horizontal clamping to fix the valve body, and then install the components one by one onto the valve body to achieve the effect of assembling the electromagnetic pressure reducing valve. However, because electromagnetic pressure reducing valves require the components to be assembled from multiple different angles, and the assembly fixture is always in a clamping and fixed state, the operator needs to adjust the clamping position multiple times or adjust the assembly station position by himself, which reduces the efficiency of electromagnetic pressure reducing valve assembly.

[0004] Therefore, a new solution is needed to address the above problems. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a clamp.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

A fixing rod is installed in the guide groove, and the fixing rod passes through the guide slider. A spring is sleeved on the fixing rod, and the two ends of the spring are respectively connected to the back of the guide slider and the outer wall of the guide groove.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example: A clamp, such as Figures 1-5 As shown, the device includes a turntable 1, which is rotatably connected to an operating table 2 and is detachably connected to the operating table 2. A toothed ring 3 coaxial with the turntable 1 is installed on the outer surface of the turntable 1. A clamping assembly 4 for clamping the valve body of the electromagnetic pressure reducing valve is installed on the top surface of the turntable 1. A fixing assembly 5 for constraining the clamping assembly 4 is installed on one side of the clamping assembly 4. A driving assembly 6 is installed on one side of the operating table 2. The driving assembly 6 drives the turntable 1 to rotate through the toothed ring 3.

[0029] In use, the operator places the valve body into the clamping assembly 4, which clamps the valve body. At the same time, the fixing assembly 5 constrains the clamping plate 41 to improve the stability of the clamping and fixing of the clamping plate 41. Then, one side of the valve body is assembled. When it is necessary to change the installation position of the accessories, the drive assembly 6 drives the turntable 1 to rotate, turning the valve body to the required direction, thereby achieving the effect of the operator assembling the valve body in multiple directions in the same position.

[0030] Furthermore, such as Figure 1As shown, the drive assembly 6 includes a motor 61 and a gear 62. The motor 61 is mounted on the operating table 2, and the gear 62 is mounted on the output shaft of the motor 61, with the gear 62 coaxially arranged with the output shaft of the motor 61. The gear 62 meshes with a gear ring 3. In use, the motor 61 drives the gear 62 to rotate through the output shaft. Since the gear 62 and the gear ring 3 are meshed, the rotation of the gear 62 drives the gear ring 3 to rotate, which in turn drives the turntable 1 to rotate. In this embodiment, the outer diameter of the gear 62 is smaller than the outer diameter of the gear ring 3.

[0031] Furthermore, such as Figure 1 and Figure 2 As shown, the operating platform 2 is provided with multiple guide wheels 7 corresponding to the position of the turntable 1. The guide wheels 7 are evenly distributed on the top surface of the operating platform 2 along the circumferential direction, and the guide wheels 7 are rotatably connected to the operating platform 2. The outer side of the guide wheels 7 abuts against the outer side of the turntable 1. Support wheels 8 are symmetrically provided on both sides of the guide wheels 7. The support wheels 8 are rotatably connected to support seats 9. The support seats 9 are fixedly installed on the top surface of the operating platform 2. The support wheels 8 are installed on the top surface of the operating platform 2 through the support seats 9. The outer side of the support wheels 8 abuts against the bottom surface of the toothed ring 3.

[0032] During the rotation of turntable 1, support wheels 8 support turntable 1 to facilitate its rotation. Multiple support wheels 8 are evenly distributed along the circumference, ensuring the weight of turntable 1 is evenly distributed across them, preventing excessive or insufficient localized stress. Simultaneously, the turntable 1 is mounted on the support wheels 8, facilitating its disassembly and installation. Appropriate clamping plates 41 can be selected based on the shape and size of the valve body, allowing for flexible replacement to meet different clamping requirements and ensure optimal clamping performance. The stop wheel 7 serves as a rotation guide, restricting the direction of turntable 1's rotation. Preferably, both support wheels 8 and stop wheels 7 are made of metal.

[0033] like Figure 3 and Figure 4 As shown, the clamping assembly 4 includes two sets of clamping plates 41, which are located on opposite sides of the top surface of the turntable 1. Each set of clamping plates 41 is connected to a control mechanism 42 for controlling the movement of the corresponding clamping plate 41. In use, the valve body is placed between the two sets of clamping plates 41, and the control mechanism 42 is used to control the movement of the clamping plates 41 to clamp the valve body.

[0034] Furthermore, the bottom surface of the clamping plate 41 abuts against the top surface of the turntable 1. With the above solution, this abutment design effectively prevents the clamping plate 41 from shaking or tilting when it moves, so that the clamping plate 41 can smoothly approach the valve body along the predetermined trajectory.

[0035] Furthermore, a rubber pad 14 is bonded and fixed to the clamping surface of the clamping plate 41. In use, the rubber pad 14 contacts the valve body before the metal surface of the clamping plate 41, and achieves flexible clamping through elastic deformation. While ensuring sufficient clamping force, it avoids unnecessary damage caused by rigid clamping.

[0036] like Figure 3 and Figure 4 As shown, the control mechanism 42 includes a guide slider 421 fixed to the bottom of the clamping plate 41. The turntable 1 has a guide groove 422 for the guide slider 421 to be embedded in. A fixing rod 423 is installed in the guide groove 422. The fixing rod 423 passes through the guide slider 421, and its two ends are fixed to the inner and outer groove walls of the guide groove 422, respectively. A spring 424 is sleeved on the fixing rod 423. The two ends of the spring 424 are connected to the back of the guide slider 421 and the outer groove wall of the guide groove 422, respectively. In use, when the valve body is placed in the two sets of clamping plates 41, the two sets of springs 424 are compressed. The two sets of springs 424 exert force on the two sets of guide sliders 421, and the two sets of guide sliders slide to form a clamping force between the two sets of clamping plates 41, thereby achieving the effect of clamping and fixing the valve body.

[0037] Furthermore, the outer wall of the guide slider 421 abuts against the inner wall of the guide groove 422; with the above solution, during use, since the guide groove 422 and the guide slider 421 are in contact, the lateral swaying of the traditional slider is eliminated, and the guide slider 421 is restricted to make pure linear motion within the guide groove 422.

[0038] Furthermore, such as Figure 1 and Figure 3 As shown, a rope 10 is connected to the back of the clamping plate 41, and a hook 11 is connected to the end of the rope 10. A first hook ring 12 is installed on the edge of the top surface of the operating table 2. In the existing electromagnetic pressure reducing valve, during assembly, one set of clamping plates is first pushed outward to form an area between the two sets of clamping plates to accommodate the valve body. After the valve body is placed in this area, one set of clamping plates abuts against the valve body under the action of spring force. Then the position of the valve body is adjusted so that both sets of clamping plates exert force on the valve body to effectively clamp the valve body. This has certain operational inconveniences. By using the hook 11, rope 10, and first hook ring 12 in combination, before the valve body is placed on the turntable 1, the two sets of clamping plates 41 are first pushed outward, and the hook 11 hooks the first hook ring 12 to constrain the two sets of clamping plates 41. Then, the valve body is placed at the center of the turntable 1, that is, between the two sets of clamping plates 41. Next, the first hook ring 12 is disengaged from the hook 11, and the two sets of clamping plates 41 abut against the valve body under the elastic force of the spring 424, clamping and fixing the valve body. Although the above scheme increases the clamping plate 41 constraint process, it avoids the process of adjusting the valve body position multiple times.

[0039] Preferably, a second hook 13 is installed on the back of the clamp 41, which can hook the hook 11 onto the second hook 13 after the hook 11 is disengaged from the first hook 12.

[0040] Furthermore, such as Figure 3 and Figure 5 As shown, the fixing assembly 5 includes two sets of support plates 51 respectively fixed to one end of two sets of clamping plates 41. A screw 52 is hinged to the inner wall of the end of one set of support plates 51, and the screw 52 can rotate horizontally around the hinge axis. A slot 53 is provided at the end of the other set of support plates 51, and the middle part of the screw 52 is movably engaged in the slot 53. When the two sets of clamping plates 41 clamp the valve body, rotating the screw 52 engages it in the slot 53, thereby locking and fixing the two sets of clamping plates 41. After the valve body is assembled, the screw 52 is first disengaged from the slot 53 to release the locking of the two sets of clamping plates 41, and then the assembled valve body is removed.

[0041] Preferably, one end of the screw 52 is threadedly connected to a locking ring 54; when the screw 52 is engaged in the slot 53, the position of the locking ring 54 is adjusted by rotating the locking ring 54, so that one end of the locking ring 54 abuts against the outer wall of the other set of support ends, thereby locking the two sets of clamping plates 41 by locking the two sets of support plates 51, and improving the locking effect of the two sets of clamping plates 41.

[0042] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected by this utility model. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
