Description

Technical Field

[0001] The utility model relates to the technical field of valve clamps, in particular to a valve clamping device for valve processing. Background Art

[0002] A valve is a device used to control the flow of fluids (liquids, gases, powders). During the production and processing process, the valve surface needs to be ground, polished, cut, and other operations. In order to prevent the valve from shaking during processing, the valve needs to be fixed.

[0003] Therefore, a valve clamping device for valve processing, with the publication number CN221696613U, first drives the rotating shaft to move through the cylinder, thereby pushing the slider to slide above the guide rail, and then drives the rotating plate to move, and then drives the triangular rotating plate to rotate on the outer wall of the rotating shaft through the movement of the rotating plate, thereby driving the three sliders to move synchronously on the outer wall of the guide rail, and then drives the three blocks to move through the base to support and fix the valve externally, achieving a fixing effect.

[0004] However, because the rotating plate and the triangular rotating plate are both made of rigid materials, that is, the size is not adjustable, the three clamping blocks in the working state are fixed at a distance relative to the center of the workbench, which means that the three clamping blocks can only clamp valves of fixed shapes. Utility Model Content

[0005] The purpose of the utility model is to solve the problems existing in the prior art and to propose a valve clamping device for valve processing.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a valve clamping device for valve processing, comprising a clamping table, the clamping table surface is provided with a plurality of slide grooves distributed in a circular array, a slider is slidably connected in the slide groove, the plurality of sliders move at the same speed and a clamping block is inserted into the side of the slider toward the center of the clamping table surface, one side of the clamping block is fixedly connected to a screw rod penetrating the side of the slider and one side of the clamping block is rotatably connected to a nut threadedly connected to the screw, a plurality of long-rod bolts are threadedly penetrated on one side of the clamping block, the end face of the rod of the long-rod bolt faces the center of the clamping table surface and is fixedly connected to an anti-slip ball.

[0007] Preferably, a slot is formed on the inner wall of the slide, and the side of the slider extends outward to be plugged into the inner wall of the slot.

[0008] Preferably, a plurality of electric telescopic rods distributed in a circular array are fixedly connected to the center of the bottom of the clamping platform, and the telescopic ends of the electric telescopic rods penetrate the surface of the clamping platform and extend upward and are also fixedly connected to anti-slip balls.

[0009] Preferably, the side of the slider facing away from the electric telescopic rod is fixedly connected to an elastic rope that passes through the bottom of the clamping platform. The elastic rope moves in a V-shaped route and one end is fixed to the bottom of the clamping platform.

[0010] Preferably, the slider is fixedly connected to a traction rope on one side facing the electric telescopic rod. The traction rope is arranged parallel to the slide groove and one end of the clamping table bottom is close to the center. The bottom of the clamping table is rotatably connected to a rotating block connected to one end of several traction ropes.

[0011] Preferably, the rotating block is sleeved on the cylinder bodies of a plurality of electric telescopic rods and a wire-receiving groove for receiving the traction rope is opened on the side of the rotating block.

[0012] Preferably, the bottom of the clamping table is rotatably connected to a spur gear driven by a motor, and the side of the rotating block is also provided with a spur tooth surface meshing with the spur gear.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are:

[0014] 1. In the present invention, by rotating the nut on the slider, the screw threadedly connected thereto can drive the fixedly mounted clamping block to move when plugged into the slider.

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figure 1-4 As shown, a valve clamping device for valve processing includes a clamping table 1, a plurality of slide grooves 2 distributed in a ring array are opened on the surface of the clamping table 1, a slider 6 is slidably connected to the slide groove 2, a card slot 15 is opened on the inner wall relative to the slide groove 2, the side of the slider 6 extends outward to be plugged into the inner wall of the card slot 15, and the provided card slot 15 ensures that the slider 6 can only move along the length direction of the slide groove 2, and several sliders 6 move at the same speed and a card block 16 is inserted on the side of the slider 6 toward the center of the clamping table 1. The valve is placed on the center of the clamping table 1, and several sliders 6 move toward the center of the clamping table 1 at the same time. The card block 16 set on its surface is used to fit the valve surface to achieve valve clamping and fixation. One side of the card block 16 is fixedly connected to a screw rod 12 set through the side of the slider 6 and one side of the card block 16 is rotatably connected to a nut 13 threadedly connected to the screw 12. By rotating the nut 13 on the slider 6, the screw 12 threadedly connected to it can drive the fixed block 16 to move when it is plugged into the slider 6. Therefore, it is convenient to adjust the initial relative position of the block 16 and the slider 6 according to the shape of the outer wall of the valve, thereby ensuring that after several sliders 6 move the same distance, the block 16 on its surface can fit and clamp the valve surface. Several long-rod bolts 4 are threaded through one side of the block 16. The end face of the long-rod bolt 4 faces the center of the table surface of the clamping platform 1 and is fixedly connected with an anti-slip ball 5. After adjusting the position of the block 16, the relative position of several anti-slip balls 5 on the side of the block 16 can be adjusted by rotating the long-rod bolt 4 according to the shape and amplitude of the outer wall of the valve, so that the distribution route of the several anti-slip balls 5 is consistent with the shape of the valve surface, which facilitates the use of several anti-slip balls 5 to further clamp the valve surface.

[0024] In addition: a number of electric telescopic rods 3 distributed in a circular array are fixedly connected to the center of the bottom of the clamping platform 1. The telescopic ends of the electric telescopic rods 3 pass through the surface of the clamping platform 1 and extend upward and are also fixedly connected to anti-slip balls 5. Similarly, according to the shape and degree of concavity of the contact surface between the valve and the surface of the clamping platform 1, the electric telescopic rods 3 are used to adjust the installation height of the anti-slip balls 5 at their telescopic ends, thereby ensuring that when the valve is placed on the clamping platform 1, the anti-slip balls 5 at the telescopic ends of the electric telescopic rods 3 are used to support the uneven parts of the bottom surface of the valve, ensuring that the valve will not tilt or shake during the movement of the sliders 6.

[0025] In addition: the side of the slider 6 facing away from the electric telescopic rod 3 is fixedly connected to an elastic rope 7 that passes through the bottom of the clamping platform 1. The elastic rope 7 moves in a V-shaped route and one end is fixed to the bottom of the clamping platform 1. The side of the slider 6 facing the electric telescopic rod 3 is fixedly connected to a traction rope 8. The traction rope 8 is arranged parallel to the slide groove 2 and one end of the bottom surface of the clamping platform 1 is close to the center. The bottom of the clamping platform 1 is rotatably connected to a rotating block 9 connected to one end of several traction ropes 8. The rotating block 9 is sleeved on the cylinder body of several electric telescopic rods 3 and a wire-receiving groove for receiving the traction rope 8 is opened on the side of the rotating block 9 14. The bottom of the clamping table 1 is connected to a spur gear 10 driven by a motor. The side of the rotating block 9 is also provided with a spur tooth surface 11 meshing with the spur gear 10. In this solution, the spur gear 10 is driven to rotate by installing a motor embedded in the bottom of the clamping table 1, thereby realizing the meshing connection of the spur tooth surface 11 to drive the rotating block 9 to rotate, and the wire-receiving groove 14 on the surface of the rotating block 9 is used to wind the traction rope 8. When the traction rope 8 is passively wound, it will pull the slider 6 to move toward the rotating block 9, and when the slider 6 moves, it will correspondingly pull the elastic rope 7 to elastically stretch. In addition, as Figure 2 As shown, the elastic rope 7 moving in a V-shaped route and the traction rope 8 passing through the bottom of the clamping table 1 ensure that the pulling force applied by the traction rope 8 to the slider 6 is perpendicular to the side of the slider 6, and the pulling force applied by the slider 6 to the elastic rope 7 is also perpendicular to the side of the slider 6, ensuring balanced force. Conversely, when the turning block 9 reverses and releases the traction rope 8, the elastic contraction of the elastic rope 7 can be used to reset the slider 6.

[0026] Working principle: first adjust the relative height of several anti-slip balls 5 on the surface of the clamping table 1, place the valve on the several anti-slip balls 5, and then use the motor to drive the spur gear 10 to rotate, so that the meshing spur tooth surface 11 drives the rotating block 9 to rotate, and use the wire take-up groove 14 to wind the traction rope 8. When the traction rope 8 is passively wound, it will pull the slider 6 toward the rotating block 9, and according to the shape and actual size of the clamped area on the side of the valve, by rotating the nut 13 on the slider 6, the screw 12 threadedly connected to it can drive the fixedly installed block 16 to move when it is plugged into the slider 6, or further by rotating the long rod bolt 4, the relative position of several anti-slip balls 5 on the side of the block 16 can be adjusted, so that the distribution route of several anti-slip balls 5 is consistent with the shape of the valve surface, which is convenient for further clamping the valve surface with several anti-slip balls 5.

[0027] The wiring diagram of the electric telescopic rod 3 and the motor in the present invention is common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use. Therefore, the control method and wiring arrangement of the electric telescopic rod 3 and the motor are not explained in detail.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
