Description

Technical Field

[0001] The utility model belongs to the technical field of plastic valve processing, and particularly relates to a processing fixture for plastic valves. Background Art

[0002] A plastic valve is a valve made of plastic materials (such as polypropylene (PP), polyvinyl chloride (PVC), polyvinylidene fluoride (PVDF), etc.), and is mainly applied to fluid control systems with special requirements for corrosion resistance in water treatment, chemical industry, medicine, food processing, agricultural irrigation, etc.

[0003] For the existing processing fixture for plastic valves, the screw rod is rotated by a motor, and then the screw rod drives the clamping seats on the left and right sides to move closer to each other to quickly clamp the two ends of the plastic valve. Then, the motor drives the clamping seats to rotate to adjust the angle of the plastic valve to facilitate the processing of the plastic valve. However, in the actual use process, due to the relatively single clamping direction of the plastic valve, during the processing of the plastic valve, the vibration generated by the contact between the processing equipment and the plastic valve may cause a certain degree of position deviation of the plastic valve, which may further affect the processing accuracy. Summary of the Utility Model

[0004] In view of this, aiming at the deficiencies of the prior art, the utility model provides a processing fixture for plastic valves. After the two ends of the plastic valve are fixed by two clamping seats, the plastic valve is internally supported and fixed by a clamping rod, so that the plastic valve to be processed can be fixed quickly and efficiently.

[0005] To solve the above technical problems, the technical scheme adopted by the utility model is: a processing fixture for plastic valves, including a tooling table. Four corners of the lower surface of the tooling table are respectively provided with supporting feet. The upper surface of the tooling table is provided with a mounting seat. Four uniformly distributed guiding sliding grooves are opened on the upper surface of the mounting seat. Sliding seats are respectively slidably arranged between the guiding sliding grooves on the front and rear sides. The upper surfaces of the sliding seats are respectively provided with brackets. The upper sides of the opposite inner sides of the two brackets are respectively rotatably provided with clamping seats through rotating shafts. Four uniformly distributed sliding grooves are respectively opened on the opposite inner sides of the two clamping seats. Clamping rods are respectively slidably arranged inside the sliding grooves. The upper sides inside the brackets are respectively provided with driving motors. The output shafts of the driving motors are respectively fixed to the adjacent rotating shafts through couplings. A driving module for driving the clamping rods to move is further arranged on the clamping seats. An electric control module for driving the clamping seats to move is further arranged on the mounting seat.

[0006] As a further improvement of the present utility model, the electronic control module includes two supports symmetrically welded and fixed to the inner bottom end of the mounting seat. Between each support and the adjacent inner wall of the mounting seat, an adjusting screw rod is rotatably arranged. The adjusting screw rods are respectively threadedly connected to the adjacent sliding seats. The mounting seat is also provided with an electric drive unit for driving the rotation of the adjusting screw rods; the electric drive unit includes a double-shaft motor arranged in the middle of the inner bottom end of the mounting seat. The output shafts of the double-shaft motor are respectively fixed to the adjacent adjusting screw rods through couplings; a controller is arranged on the front side of the upper surface of the mounting seat. The double-shaft motor and the drive motor are both electrically connected to the controller.

[0007] As a further improvement of the present utility model, the drive module includes linkage blocks welded and fixed to one end of each clamping rod away from the vertical center of the mounting seat. Between the interiors of two adjacent linkage blocks, sliding columns are respectively slidably arranged. Between two adjacent linkage blocks, return springs are respectively arranged. The return springs are all sleeved on the outer side surfaces of the sliding columns. The clamping seat is also provided with a drive unit for driving the movement of the linkage blocks; the drive unit includes a bidirectional screw rod rotatably arranged inside the clamping seat. The outer sides of the bidirectional screw rod are respectively threadedly connected to the adjacent linkage blocks. Handwheels are arranged at the front ends of the bidirectional screw rods.

[0008] As a further improvement of the present utility model, sponge sleeves are fixedly sleeved on the outer sides of the clamping rods. Rubber pads are adhesively fixed to the opposite inner side surfaces of the two clamping seats.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0010] Firstly, the controller regulates the operation of the double-shaft motor. By the threaded relationship between the adjusting screw rod and the sliding seat, the sliding seats on the left and right sides are driven to move closer to each other, so that the sliding seats on the left and right sides drive the clamping seats on the left and right sides to move closer to each other through the brackets, and the plastic valve is quickly and stably clamped from left and right.

[0011] Secondly, rotate the handwheels on the left and right sides to make the bidirectional screw rods drive the two linkage blocks threadedly connected to them to move in the opposite direction respectively. Through the sliding relationship between the linkage blocks and the sliding columns, the four linkage blocks are driven to move in the opposite direction synchronously, so that the clamping rods can quickly and firmly internally support and fix the plastic valve. After the two ends of the plastic valve are fixed by the two clamping seats and then internally supported and fixed by the clamping rods, the plastic valve to be processed can be fixed quickly and efficiently.

[0012] Thirdly, the controller regulates the synchronous operation of the drive motors on the left and right sides, so that the output shafts of the drive motors drive the clamping seats to rotate through the rotating shafts, and thus the angle of the plastic valve fixed between the two clamping seats can be quickly adjusted.

[0013] Fourthly, the sponge sleeve and the rubber pad enable the clamping rod and the clamping seat to be in flexible contact with the plastic valve, which can effectively avoid damage to the plastic valve caused by clamping during the processing of the plastic valve.

In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details.

[0021] Such as Figure 1 、 2As shown in Figures 3 and 4, it includes a tooling table 101. Support feet 102 are provided at the four corners of the lower surface of the tooling table 101. An installation seat 103 is provided on the upper surface of the tooling table 101. Four uniformly distributed guiding chutes 104 are provided on the upper surface of the installation seat 103. Sliding seats 105 are respectively slidably arranged between the guiding chutes 104 on the front and rear sides. Brackets 106 are provided on the upper surfaces of the sliding seats 105. Clamping seats 107 are respectively rotatably arranged on the upper sides of the opposite inner sides of the two brackets 106 through rotating shafts. Four uniformly distributed sliding grooves 108 are provided on the opposite inner sides of the two clamping seats 107. Clamping rods 109 are respectively slidably arranged inside the sliding grooves 108. Driving motors 113 are respectively provided on the upper sides inside the brackets 106. The output shafts of the driving motors 113 are respectively fixedly connected to the adjacent rotating shafts through couplings. A driving module for driving the clamping rods 109 to move is further provided on the clamping seats 107. An electric control module for driving the clamping seats 107 to move is further provided on the installation seat 103.

[0022] As Figure 2 , 3 As shown in Figures 3, 5 and 4, the electric control module includes two supports 111 symmetrically welded and fixed to the bottom end inside the installation seat 103. Adjusting lead screws 110 are respectively rotatably arranged between the two supports 111 and the inner walls of the adjacent installation seats 103. The adjusting lead screws 110 are respectively threadedly connected to the adjacent sliding seats 105. An electric driving unit for driving the adjusting lead screws 110 to rotate is further provided on the installation seat 103; the electric driving unit includes a double-shaft motor 112 arranged in the middle of the bottom end inside the installation seat 103. The output shafts of the double-shaft motor 112 are respectively fixedly connected to the adjacent adjusting lead screws 110 through couplings.

[0023] As Figure 2 , 3 As shown in Figures 3, 6 and 4, the driving module includes linkage blocks 201 welded and fixed to one end of each clamping rod 109 away from the vertical center of the installation seat 103. Slide columns 202 are respectively slidably arranged between the interiors of the adjacent two linkage blocks 201. Return springs 203 are respectively arranged between the adjacent two linkage blocks 201. The return springs 203 are all sleeved on the outer sides of the slide columns 202. A driving unit for driving the linkage blocks 201 to move is further provided on the clamping seats 107; the driving unit includes a bidirectional lead screw 204 rotatably arranged inside the clamping seats 107. The outer sides of the bidirectional lead screw 204 are respectively threadedly connected to the adjacent linkage blocks 201. Handwheels 205 are respectively provided at the front ends of the bidirectional lead screws 204.

[0024] As Figure 1 , 4 As shown in Figure 3, a controller 301 is provided on the front side of the upper surface of the installation seat 103. The double-shaft motor 112 and the driving motors 113 are both electrically connected to the controller 301.

[0025] When plastic valves need to be processed, the operator adjusts the operation of the dual-axis motor 112 through the controller 301, causing the output shafts of the dual-axis motor 112 to drive the adjusting lead screws 110 connected thereto to rotate respectively. Then, due to the threaded relationship between the adjusting lead screws 110 and the sliding seats 105, the sliding seats 105 on the left and right sides are driven to move closer to each other, causing the clamping seats 107 on the left and right sides to move closer to each other through the brackets 106, so as to quickly and stably clamp the plastic valve on the left and right sides. Then, the operator rotates the handwheels 205 on the left and right sides, causing the handwheels 205 to drive the bidirectional lead screws 204 connected thereto to rotate respectively. As a result, the bidirectional lead screws 204 drive the two linkage blocks 201 threadedly connected thereto to move in a direction away from each other. During the movement of the two linkage blocks 201 threadedly connected to the bidirectional lead screw 204, the four linkage blocks 201 are driven to move synchronously in a direction away from each other through the sliding relationship between the linkage blocks 201 and the sliding columns 202, driving the four clamping rods 109 to move synchronously in a direction away from each other. By driving the four clamping rods 109 on the left side and the four clamping rods 109 on the right side to move synchronously in a direction away from each other, the clamping rods 109 can quickly and firmly internally support and fix the plastic valve. After the two ends of the plastic valve are fixed by the two clamping seats 107 and then internally supported and fixed by the clamping rods 109, the plastic valve to be processed can be fixed quickly and efficiently. During the processing, the controller 301 adjusts the synchronous operation of the driving motors 113 on the left and right sides, causing the output shafts of the driving motors 113 to drive the clamping seats 107 to rotate through the rotating shafts, so as to quickly adjust the angle of the plastic valve fixed between the two clamping seats 107.

[0026] According to another embodiment of the present invention, as Figure 1 、 2 、shown in FIG. 4, sponge sleeves 114 are fixedly sleeved on the outer sides of the clamping rods 109, and rubber pads are adhesively fixed on the opposite inner sides of the two clamping seats 107. During the processing of the plastic valve, the sponge sleeves 114 and the rubber pads enable the clamping rods 109 and the clamping seats 107 to be in flexible contact with the plastic valve, effectively avoiding damage to the plastic valve caused by clamping.
