Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic valves, in particular to a clamping device for machining electromagnetic valves. Background Art

[0002] A solenoid valve is an industrial device controlled by electromagnetics. It is a basic automation component used to control fluids. It is an actuator used in industrial control systems to adjust the direction, flow, speed and other parameters of the medium. The solenoid valve can be used in conjunction with different circuits to achieve the desired control, and the control accuracy and flexibility can be guaranteed.

[0003] The solenoid valve body needs to be clamped with a clamp during the machining process. Due to the different functions and sizes of solenoid valves, different clamping molds need to be replaced to clamp the valve body when processing different types of solenoid valves. Currently, the clamping mold is mainly fixed to the clamp base by bolts. When replacing the clamping mold, it is necessary to frequently use tools to turn the bolts for fixing and disassembly, which results in a lot of time spent on replacing the clamping mold.

[0004] In view of this, a clamping device for solenoid valve processing which is convenient for quickly replacing the clamping mold is proposed to solve the above problems. Utility Model Content

[0005] In order to overcome the disadvantage that the clamping mold is mainly fixed to the clamp base by bolts, and when replacing the clamping mold, it is necessary to frequently use tools to turn the bolts for fixing and disassembly, resulting in a large amount of time required to replace the clamping mold, the utility model provides a clamping device for solenoid valve processing that is convenient and quick to replace the clamping mold.

[0006] The technical solution is: a clamping device for solenoid valve processing, including a base frame, a handwheel, a bidirectional screw and a clamping plate. A bidirectional screw is rotatably arranged on the base frame, one end of the bidirectional screw is fixedly connected to a handwheel, and clamping plates are rotatably arranged on both ends of the bidirectional screw. The clamping plates slide on the base frame, and also include a clamp module, a fixed sleeve, a limiting sleeve, a tapered rod, a ball and a first elastic member. There are two clamp modules, and two fixed sleeves are fixedly connected to the sides of the two clamp modules away from each other. The sides of the two clamps away from each other are penetrated by the limiting sleeve, the fixed sleeve is slidably connected to the limiting sleeve, a tapered rod is slidably arranged in the limiting sleeve, two balls are slidably arranged between the limiting sleeve and the tapered rod, and a first elastic member is connected between the limiting sleeve and the tapered rod, and the tapered rod slides to extrude the ball to slide outward and clamp with the fixed sleeve.

[0007] As a further preferred scheme, it also includes a fixing rod, a second elastic member and a limit block. Two fixing rods are fixedly connected to the lower part of one splint, and two limit blocks are fixedly connected to the lower part of the other splint. The fixing rod is slidably connected to the adjacent limit blocks, and the second elastic member is sleeved on the fixing rod.

[0008] As a further preferred scheme, it also includes a gear ring fixing seat, a ratchet ring, a sliding ring, a block and a torsion spring. Two gear ring fixing seats are fixedly connected to the side of the base frame close to the handwheel, a ratchet ring is installed between the two gear ring fixing seats, a sliding ring is slidably arranged on the end of the bidirectional screw close to the handwheel, a block is rotatably arranged on the end of the sliding ring close to the ratchet ring, and the block is in contact with the ratchet ring, and a torsion spring is connected between the sliding ring and the block.

[0009] As a further preferred scheme, it also includes a first limit frame, a connecting plate, a first screw, a second limit frame, a fixed plate and a second screw. The first limit frame is rotatably connected to the first screw, and two connecting plates are threadedly arranged on the first screw, and the two connecting plates are fixedly connected to the bottom of the base frame. The second limit frame is rotatably connected to one side of the second limit frame, and two fixed plates are threadedly arranged on the second screw, and the two fixed plates are fixedly connected to the first limit frame.

[0010] As a further preferred solution, there are grooves on both sides of the clamp module.

[0011] As a further preferred solution, a rubber sleeve is also included, and the end of the sliding ring away from the clamping block is sleeved with the rubber sleeve.

[0012] The utility model has the following advantages: 1. By pushing the conical rod, the ball is no longer stuck in the fixed sleeve, and the clamp module can be removed for replacement. After the fixed sleeve on the new clamp module is aligned with the limit sleeve, the conical rod is loosened. Under the action of the first elastic member, the conical rod causes the ball to be clamped with the inside of the fixed sleeve, thereby achieving the purpose of quickly replacing the clamp module.

[0013] 2. Turn the hand wheel to make the two clamp modules cooperate to clamp the valve body, and the clamp block engages with the teeth inside the ratchet ring to fix the bidirectional screw and prevent the bidirectional screw from rotating in the opposite direction during valve body processing, causing the clamp module to loosen the valve body.

[0014] 3. By rotating the first screw and the second screw, the left-right and front-back positions of the chassis can be quickly adjusted, making it convenient to process different positions of the valve body. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The present invention is further described below in conjunction with specific embodiments. It should also be noted that, unless otherwise clearly specified and limited, terms such as: setting, installing, connecting, and connecting should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Embodiment 1: A clamping device for machining a solenoid valve, see Figure 1-Figure 3As shown, it includes a base frame 1, a hand wheel 2, a bidirectional screw 3 and a clamping plate 4. The base frame 1 is a cavity structure with a slide groove on the top. The bidirectional screw 3 is rotatably arranged on the base frame 1. The left end of the bidirectional screw 3 is fixedly connected to the hand wheel 2 by welding. Clamping plates 4 are rotatably arranged on both ends of the bidirectional screw 3. The clamping plate 4 slides in the slide groove on the top of the base frame 1. There are two clamp modules 5. Grooves 25 are arranged on both sides of the clamp module 5. The clamp module 5 can be replaced by inserting fingers into the groove 25. The two clamps Two fixed sleeves 6 are fixedly connected to the outside of the module 5, and the limiting sleeves 7 are passed through the outside of the two splints 4. The inner diameter of the fixed sleeve 6 is larger than the outer diameter of the limiting sleeve 7. The fixed sleeve 6 is sleeved on the limiting sleeve 7 and is slidably connected. A conical rod 8 is slidably arranged in the limiting sleeve 7, and two balls 9 are slidably arranged between the limiting sleeve 7 and the conical rod 8. A first elastic member 10 is connected between the limiting sleeve 7 and the conical rod 8, and the first elastic member 10 is sleeved on the conical rod 8. The conical rod 8 slides to squeeze the balls 9 to slide outward and engage with the fixed sleeve 6.

[0025] When the solenoid valve body needs to be clamped, the valve body is placed between the two clamp modules 5, and then the hand wheel 2 is turned, and the bidirectional screw 3 drives the clamp module 5 to move toward the side close to each other through the clamp plate 4, so that the two clamp modules 5 cooperate to clamp the valve body. When different types of clamp modules 5 are replaced, the cone rod 8 is pushed to one side of the clamp module 5, and the cone rod 8 squeezes the first elastic member 10 to deform, and the cone surface on the cone rod 8 no longer presses against the ball 9. At this time, the ball 9 can move freely in the gap between the cone rod 8 and the limiting sleeve 7, so that The ball 9 no longer jams the fixed sleeve 6, and the clamp module 5 is removed for replacement. After the fixed sleeve 6 on the new clamp module 5 is aligned with the limit sleeve 7, the sliding clamp module 5 is pressed against the clamp plate 4, and then the conical rod 8 is released. The first elastic member 10 returns to its original state and drives the conical rod 8 to slide to the side away from the clamp module 5. The conical surface on the conical rod 8 presses against the ball 9 to slide toward the fixed sleeve 6, and the ball 9 is engaged with the inside of the fixed sleeve 6, so that the clamp module 5 is quickly fixed on the clamp plate 4, thereby achieving the purpose of quickly replacing the clamp module 5.

[0026] Example 2: Based on Example 1, refer to Figure 4 As shown, it also includes a fixing rod 11, a second elastic member 12 and a limit block 13. The left and right sides of one splint 4 are fixedly connected with the fixing rod 11, and the left and right sides of the lower part of the other splint 4 are fixedly connected with the limit blocks 13. The fixing rod 11 is slidably connected to the adjacent limit blocks 13. The second elastic member 12 is sleeved on the fixing rod 11, and the two ends of the second elastic member 12 are respectively connected to the limit blocks 13 and the fixing rod 11.

[0027] When the clamp plate 4 drives the clamp module 5 to move toward one side closer to each other, the fixing rod 11 is inserted into the limit block 13, and the fixing rod 11 squeezes the second elastic member 12 to deform, so that the fixing rod 11 cooperates with the limit block 13 to guide the clamp plates 4 and the clamp module 5 on both sides, thereby ensuring that the clamp modules 5 on both sides remain aligned when clamping the valve body.

[0028] See also Figure 4 and Figure 6 As shown, it also includes a gear ring fixing seat 14, a ratchet ring 15, a sliding ring 16, a block 17 and a torsion spring 18. Two gear ring fixing seats 14 are fixedly connected to one side of the base frame 1 close to the hand wheel 2 by welding. The ratchet ring 15 is installed between the two gear ring fixing seats 14 by bolt connection. A connecting key is installed at the left end of the bidirectional screw 3. A sliding ring 16 is slidably provided at the left end of the bidirectional screw 3. The sliding ring 16 is slidably connected to the connecting key on the bidirectional screw 3. A block 17 is rotatably provided at one end of the sliding ring 16 close to the ratchet ring 15, and the block 17 is in contact with the ratchet ring 15. Two torsion springs 18 are connected between the sliding ring 16 and the block 17. Two ends of the torsion spring 18 are respectively connected to the sliding ring 16 and the block 17. A rubber sleeve 26 is sleeved on one end of the sliding ring 16 away from the block 17. When the sliding ring 16 is moved, the rubber sleeve 26 can increase the friction between the sliding ring 16 and the hand.

[0029] When it is necessary to clamp the solenoid valve body, the hand wheel 2 is turned counterclockwise, and the hand wheel 2 drives the bidirectional screw 3, the sliding ring 16, the block 17 and the torsion spring 18 to rotate. When the block 17 contacts the teeth inside the ratchet ring 15, the teeth inside the ratchet ring 15 squeeze the block 17 to rotate downward, and the block 17 drives the torsion spring 18 to deform. When the two clamp modules 5 cooperate to clamp the valve body, stop turning the hand wheel 2, and the torsion spring 18 returns to its original state to drive the block 17 to rotate upward and engage with the teeth inside the ratchet ring 15, thereby fixing the bidirectional screw 3 to prevent the bidirectional screw 3 from rotating in the opposite direction during valve body processing, causing the clamp module 5 to loosen the valve body. After the valve body processing is completed, first slide the sliding ring 16, the block 17 and the torsion spring 18 to slide forward to disengage the block 17 from the teeth inside the ratchet ring 15, and then turn the hand wheel 2 clockwise to loosen the valve body.

[0030] See also Figure 7As shown, it also includes a first limit frame 19, a connecting plate 20, a first screw 21, a second limit frame 22, a fixing plate 23 and a second screw 24. The first limit frame 19 is rotatably connected to the middle of the first limit frame 19, and a rotating handle is fixedly connected to one end of the first screw 21. The first screw 21 is convenient to rotate by holding the rotating handle. Two connecting plates 20 are threadedly arranged on the first screw 21, and the two connecting plates 20 are fixedly connected to the bottom of the base frame 1 by bolt connection. The second limit frame 22 is rotatably connected to one side of the second limit frame 22, and two fixing plates 23 are threadedly arranged on the second screw 24, and the two fixing plates 23 are fixedly connected to the first limit frame 19.

[0031] When the position of the valve body needs to be adjusted, the first screw 21 is rotated, and the first screw 21 drives the base frame 1 on the first limit frame 19 to move left and right, so that the position of the base frame 1 can be adjusted left and right. The second screw 24 is rotated, and the second screw 24 drives the first limit frame 19 to move forward and backward in the second limit frame 22, so that the position of the base frame 1 can be adjusted forward and backward, so that the base frame 1 can be quickly adjusted, which is convenient for processing different positions of the valve body.
