Description

Technical Field

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

[0002] The clamping assembly for valve processing is an indispensable and important part in the valve processing process, and it plays a key role in improving the processing efficiency, ensuring the processing accuracy and the workpiece quality.

[0003] In order to stably clamp valves of different sizes, the existing valve clamps are generally equipped with clamping plates of various specifications. However, the clamping plates in the existing technology are usually installed on the clamp by screws. The screw installation method cannot achieve the quick disassembly and assembly of the clamping plates. The screw installation method requires the operator to tighten or loosen the screws one by one when replacing the clamping plates. This process is both time-consuming and laborious. In the valve processing process, if it is necessary to frequently replace the clamping plates according to valves of different sizes, the screw installation method will greatly reduce the efficiency of the production line.

[0004] Therefore, it is necessary to design a clamping assembly for valve processing to solve the above problems. Content of the Utility Model

[0039] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0040] Referring to Figures 1-4 , a clamping component for valve processing includes a driving module 1. The driving module 1 includes a frame, a motor and a lead screw. The motor is installed on the frame, the lead screw is rotatably installed on the frame, and one end of the lead screw is connected to the output shaft of the motor. There are two thread sections with the same length and opposite directions on the lead screw. Two moving seats 2 are respectively threadedly sleeved on the two thread sections. The motor drives the lead screw to rotate, and the two moving seats 2 can approach or move away from each other; two moving seats 2 are both arranged on the driving module 1, and the two moving seats 2 are both slidably assembled on the frame to prevent the moving seats 2 from rotating along with the lead screw; two mounting plates 3 are respectively fixed on the two moving seats 2; two clamping plates 4 are respectively installed on the two mounting plates 3; two assembly ports 5 are respectively opened on the two mounting plates 3; two mounting blocks 6 are respectively fixed on the sides of the two clamping plates 4, and the interior is hollow. Threaded ports are opened on the two mounting blocks 6, and the threaded ports are communicated with the cavities inside the mounting blocks 6;

[0041] The clamping assembly further includes two clamping structures, which are respectively arranged on the two mounting blocks 6. The clamping structure includes: two openings 71, both of which are opened on the side surface of the mounting block 6 and communicate with the cavity inside the mounting block 6; two clamping blocks 72, which are respectively slidably arranged in the two openings 71; two guide plates 73, which are respectively fixed on the side surfaces of the two clamping blocks 72 and are both placed in the cavity inside the mounting block 6. The side surface of the guide plate 73 is in close contact with the inner wall of the cavity; a guide rod 74, which is fixed in the cavity inside the mounting block 6. The two guide plates 73 are both slidably sleeved on the guide rod 74. The guide plate 73 and the guide rod 74 play a role in limiting the movement of the clamping block 72 to ensure the stability of the clamping block 72 during the movement; a spring 75, which is arranged between the two guide plates 73. The spring 75 is used to realize the automatic reset of the two clamping blocks 72.

[0042] The clamping assembly further includes two adjusting structures, which are respectively arranged on the two mounting blocks 6. The adjusting structure includes: a screw rod 81, which is threadedly sleeved in the threaded opening. One end of the screw rod 81 located outside the cavity is equipped with a knob; a control block 82, which is fixed at one end of the screw rod 81 located inside the cavity. The cross section of the control block 82 is in a frustum shape. The screw rod 81 and the control block 82 are coaxially arranged; two ejector rods 83, which are respectively fixed on the two clamping blocks 72 and are both placed in the cavity inside the mounting block 6. The two ejector rods 83 are respectively placed on both sides of the control block 82. When the screw rod 81 rotates, it can move and drive the control block 82 to move. Since the cross section of the control block 82 is in a frustum shape, when the control block 82 moves, the two ejector rods 83 will move synchronously under the action of the outer surface of the control block 82.

[0043] The specific working principle of the present utility model is as follows:

[0044] When the clamping assembly for valve processing proposed by the present utility model is in use, the clamping plate 4 is installed on the mounting plate 3 through the clamping structure and the adjusting structure. The clamping structure and the adjusting structure are used to realize the quick disassembly and assembly of the clamping plate 4, which is convenient for the staff to quickly replace clamping plates 4 of different specifications. When disassembling the clamping plate 4, the staff first rotates the knob. When the knob rotates, it can drive the screw rod 81 to rotate. When the screw rod 81 rotates, it can move and drive the control block 82 to move. Since the cross section of the control block 82 is in a frustum shape, when the control block 82 moves, the two ejector rods 83 will move synchronously under the action of the outer surface of the control block 82. When the control block 82 moves in the direction away from the clamping plate 4, the control block 82 no longer presses the two ejector rods 83. At this time, the two ejector rods 83 will approach each other under the elastic force of the spring 75, which makes the two clamping blocks 72 respectively retract into the two openings 71. Without the restriction of the two clamping blocks 72, the mounting block 6 can slide out from the assembly opening 5, so as to realize the quick disassembly of the clamping plate 4;

[0045] When installing the clamping plate 4, the staff first inserts the installation block 6 into the assembly opening 5 until the clamping plate 4 is in contact with the installation plate 3. At this time, the staff rotates the knob in the reverse direction, causing the screw rod 81 to rotate in the reverse direction. Based on the above principle, when the screw rod 81 rotates in the reverse direction, it can drive the control block 82 to move towards the direction close to the clamping plate 4, which causes the control block 82 to squeeze the two ejector rods 83, so that the two clamping blocks 72 move away from each other. When the two clamping blocks 72 move away from each other, they can respectively extend out from the two openings 71 and be in contact with the side surface of the installation plate 3. At this time, the two clamping blocks 72 can play a limiting role on the installation block 6 to prevent the installation block 6 from sliding out of the assembly opening 5, thus realizing the rapid fixation of the clamping plate 4.

[0046] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
