Description

Technical Field

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

[0002] A fluid controller is a device used to automatically control the flow of fluid. It uses various control elements such as pumps, valves, valve cores, oil cylinders or air cylinders to form a control closed loop, which can control the circulation and flow of fluids.

[0003] According to the different working media, fluid controllers can be divided into two categories: hydraulic control and pneumatic control. Hydraulic control uses oil as the working medium, while pneumatic control uses gas. However, no matter which type of controller is used, a controller valve core is provided inside it.

[0004] During the processing of the controller valve core, the raw material is generally a whole metal rod. The metal rod is then inserted into one of the fixtures. After one end of the valve core is cut, the other fixture clamps the processed end, and then the other end is cut off as required. Then the other fixture is moved to another processing position for cutting to complete the valve core processing at the other end. Finally, the controller valve core can be obtained, and then this reciprocating process can be carried out uninterruptedly.

[0005] However, when clamping, especially when clamping the processed end, the surface of the controller valve core is easily damaged when the clamping just touches due to the large clamping force. At the same time, the three-jaw chuck clamping method is commonly used. During long-term use, the clamping position of the clamp is easily damaged, and it is not easy to replace after damage, which brings inconvenience to subsequent replacement and maintenance, and brings inconvenience to users.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] A processing fixture for a controller valve core, comprising a driving seat 10 and a connecting seat 20 connected to the driving seat 10, wherein the connecting seat 20 is fixedly connected to a fixing seat 30, and the driving seat 10 refers to a connecting structure of a clamping structure of an existing controller valve core processing device, and is used for connecting and driving the clamping structure to move and cooperate with the turning processing of the controller valve core;

[0044] In the examples of this application, please refer to Figure 1 A mounting hole 31 is provided inside the fixed seat 30 for the controller valve core to enter, and a plurality of movable holes 40 are obliquely provided inside the connecting seat 20. The movable hole 40 passes through the fixed seat 30 and is connected with the mounting hole 31. A movable column 50 is slidably provided inside the movable hole 40, and a clamping block 60 for clamping the workpiece to be processed is provided at the bottom of the movable column 50. The number of movable holes 40, movable columns 50 and clamping blocks 60 is preferably three, and they are evenly arranged in a ring shape. A driving structure 70 that is transmission-connected to the movable column 50 is provided inside the connecting seat 20. When in use, the controller valve core to be processed is placed in the mounting hole 31, and then the movable column 50 is driven relatively close by the driving structure 70 to drive the clamping block 60 to move, so as to complete the clamping of the controller valve core to be processed.

[0045] For further examples, see Figure 1 and 2 The driving structure 70 includes a motor 71 fixed inside the connecting seat 20. The motor 71 can be an existing one, such as a stepping motor or a servo motor, and is controlled in an existing manner. The output shaft of the motor 71 is fixed with a driving gear 72. The connecting seat 20 is rotatably provided with a plurality of rotating shafts 74, preferably three, one end of the rotating shaft 74 is fixed with a driven gear 73 meshing with the driving gear 72, and the other end of the rotating shaft 74 is fixed with a worm 75. The connecting seat 20 is rotatably provided with a plurality of transmission shafts 76, preferably three, the outer sides of the rotating shaft 74 and the transmission shaft 76 are sleeved with bearings, and the transmission shaft 76 is fixedly connected with a transmission gear 78 and a worm wheel 77 meshing with the worm 75. A rack 79 meshing with the transmission gear 78 is fixed to the side of the movable column 50 close to the transmission gear 78;

[0046] When in use, the starting motor 71 drives the driving gear 72 to rotate, thereby driving the driven gear 73 to rotate, which can drive the rotating shaft 74 and the worm 75 to rotate, thereby driving the worm wheel 77 to rotate, thereby driving the transmission shaft 76 and the transmission gear 78 to rotate, which can drive the rack 79 to slide, and finally drive the movable column 50 and the clamping block 60 to slide, so as to complete the clamping and un-clamping of the valve core of the controller being processed.

[0047] At the same time, after the motor 71 is started by default, the multiple movable columns 50 move synchronously and can only slide towards each other or away from each other.

[0048] For further examples, see Figure 1 , 23. The clamp block 60 is detachably connected to the movable column 50. Specifically, the connection structure between the clamp block 60 and the movable column 50 includes an operating hole 81 opened on the side of the fixing seat 30. A connecting block 82 is provided on the top of the clamp block 60. The connecting block 82 is fixedly connected to one end of a stabilizing spring 83. The other end of the stabilizing spring 83 is fixedly connected to the movable column 50. A fixing block 84 that fits the connecting block 82 is fixedly connected to the top of the clamp block 60. The fixing block 84 is fixedly connected to a guide rail 85. The cross section of the guide rail 85 is T-shaped. A guide groove is opened inside the movable column 50. The guide groove and the guide rail 85 The connecting block 82 and the fixing block 84 are matched to each other, and are connected with the screw 86. When in use, the collision generated when the clamping block 60 clamps the valve core of the processed controller will be buffered to a certain extent by the stabilizing spring 83 (the impact force generated during clamping will be transmitted to the stabilizing spring 83 through the fixing block 84 and the connecting block 82, and can be buffered by the stabilizing spring 83), so that the force generated by the clamping of the clamping block 60 and the valve core of the processed controller can be buffered, thereby protecting the valve core of the processed controller. At the same time, a rubber pad can be set at the bottom of the clamping block 60 to protect the valve core of the processed controller.

[0049] At the same time, after clamping, the movable column 50 continues to move to compress the stabilizing spring 83 to ensure clamping;

[0050] Furthermore, after the clamp block 60 is damaged after long-term use, the clamp block 60 is first moved to the end of the stroke, that is, multiple clamp blocks 60 are in contact with each other. At this time, the screw 86 is located at the operating hole 81 by default, and then a screwdriver is used to pass through the operating hole 81 to unscrew the screw 86, and then the movable column 50 is moved away from the clamp block 60. Finally, the clamp blocks 60 can be removed one by one, and vice versa, they can be installed. The operation is simple and easy to disassemble and assemble.
