Description

Technical Field

[0001] The utility model belongs to the technical field of valve production, in particular to a clamping component for valve production. Background Art

[0002] A valve is a device used to control the flow of fluids (including liquids, gases, etc.) in pipelines or equipment. It controls the flow of fluids by opening, closing or adjusting the flow area. It has multiple functions such as shutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion or overflow pressure relief. The structure of a valve usually includes a valve body, a valve cover, a valve seat, opening and closing parts (such as balls, butterfly plates), a driving mechanism (such as manual, electric, pneumatic), seals and fasteners. The clamping assembly used in valve production is a tool specially used to fix and process valves during the manufacturing or maintenance of valves. Such components are usually driven by mechanical, electrical or hydraulic means to ensure that the valve is stable and motionless during the processing operation. The existing clamping assembly for valve production uses an electrical device to drive two clamping parts towards each other to clamp the valve. However, its clamping parts are fixed on the moving mechanism, and it can only clamp and produce valves of specific sizes, which has the disadvantage of poor adaptability.

[0003] For example, the utility model with announcement number CN220972067U discloses a clamping assembly for valve production. In this patent scheme, when valves of different sizes or shapes need to be clamped, the clamping parts used to clamp the valves are fixed on the electric drive mechanism and can only adapt to valves of specific sizes. For valve factories with non-standard sizes or requiring diversified production, this limits the adaptability and efficiency of the production line. If multiple valve sizes need to be processed, multiple sets of fixed-size clamping devices need to be prepared, which increases equipment investment and storage space requirements. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology and provides a clamping assembly for valve production, which can quickly disassemble the clamping plate to adapt to valves of different sizes or shapes, reducing downtime, improving overall production efficiency and capacity, and also reducing the cost of equipment purchase and maintenance.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a clamping assembly for valve production, including a clamping table, the lower end of the clamping table is welded and fixed with two support plates corresponding to the left and right positions, two sliding grooves opened inside the clamping table are slidably provided with sliding plates, the left and right positions of the two sliding plates correspond, the upper ends of the two sliding plates are provided with cavity blocks, the interiors of the two cavity blocks are slidably provided with clamping plates, the inner arc walls of the two clamping plates are bonded with buffer pads, the interiors of the two support plates are provided with driving mechanisms for driving the two sliding plates to move, the interiors of the two cavity blocks are provided with quick-disassembly mechanisms for quickly disassembling and assembling the clamping plates, the driving mechanism includes two wires respectively arranged inside the two support plates Rod, the left and right threads of the two lead screws are opposite, and the lower end of the clamping platform is provided with an electric drive unit for driving the two lead screws to rotate, and the electric drive unit includes a dual-axis motor arranged at the lower end of the clamping platform, and the output shafts on the left and right sides of the dual-axis motor are respectively connected to the relative inner ends of the two lead screws through couplings, and the quick-disassembly mechanism includes two locking columns respectively slidably arranged inside the two cavity blocks, and locking holes are provided inside the two clamping plates, and the two locking columns are respectively plugged into the locking holes, and the upper ends of the two locking columns are provided with pull disks, and the outer arc surfaces of the two pull disks are provided with multiple evenly distributed anti-slip protrusions, and springs are respectively provided between the two pull disks and the cavity blocks, and the two springs are respectively sleeved on the outer arc surfaces of the corresponding locking columns.

[0006] As a further improvement of the present invention, a control panel is provided on the front side of the clamping table, and the dual-axis motor is electrically connected to the control panel.

[0007] As a further improvement of the present invention, a support plate is provided at the upper end of the clamping table.

[0008] As a further improvement of the present invention, two mounting holes are provided inside the support plate.

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

[0010] First, the valve to be clamped is placed on the support plate, and then the dual-axis motor is turned on through the control panel. The output shaft drives the screws on both sides to rotate. Since the screw threads on both sides are in opposite directions, the sliding plates on both sides are driven closer together, and the valve can be quickly clamped through the clamping plate inside the cavity block.

[0011] Secondly, the buffer pad on the inner arc surface of the clamping plate can prevent the valve from making hard contact with it, thereby preventing the outer surface of the valve from being clamped.

[0012] Third, by pulling the pull plates on both sides, the locking column is allowed to leave the locking hole on the clamping plate. Then the personnel can slide the clamping plate out from the cavity block. At this time, the spring is in a stretched state. Then the clamping plate that matches the size and shape of the clamped valve is slid into the cavity block. Then the pull plate is released. At this time, the spring contracts rapidly, causing the locking column to be inserted into the locking hole, thereby locking the clamping plate. Then, the control panel is used to control the dual-axis motor to open so that the replaced clamping plates are close to each other to clamp the valve again. In the process of pulling the pull plate, the anti-slip protrusion can prevent the human hand from slipping with it. The clamping plate can be quickly disassembled to adapt to valves of different sizes or shapes, reducing downtime, improving overall production efficiency and capacity, and reducing the cost of equipment purchase and maintenance.

[0013] Fourthly, the clamping assembly can be quickly installed on the valve production device through the mounting holes on the support plate, saving installation time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] To better understand the present invention, the following examples further illustrate the present invention. However, the present invention is not limited to the following examples. In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be practiced without one or more of these details.

[0021] like Figure 1 、2 As shown in Figures 3 and 4, a clamping assembly for valve production includes a clamping platform 101. Two support plates 102 corresponding to the left and right positions are welded and fixed at the lower end of the clamping platform 101. Sliding plates 105 are slidably arranged in the two sliding grooves opened inside the clamping platform 101. The left and right positions of the two sliding plates 105 correspond to each other. The upper ends of the two sliding plates 105 are provided with cavity blocks 106. Clamping plates 107 are slidably arranged inside the two cavity blocks 106. Buffer pads 109 are bonded to the inner arc walls of the two clamping plates 107. A driving mechanism for driving the two sliding plates 105 to move is provided inside the two support plates 102. The driving mechanism is a quick-disassembly mechanism for quickly disassembling and assembling the clamping plate 107, and the interior of the two cavity blocks 106 is provided with a quick-disassembly mechanism for quickly disassembling and assembling the clamping plate 107. The driving mechanism includes two screw rods 301 that are respectively rotated inside the two support plates 102, and the left and right threads of the two screw rods 301 are opposite. The lower end of the clamping platform 101 is provided with an electric drive unit that drives the two screw rods 301 to rotate. The electric drive unit includes a dual-axis motor 302 arranged at the lower end of the clamping platform 101, and the output shafts on the left and right sides of the dual-axis motor 302 are respectively connected to the opposite inner ends of the two screw rods 301 through couplings, and the upper end of the clamping platform 101 is provided with a support plate 108.

[0022] like Figure 1 、 2 As shown in Figures 3 and 4, the quick-disassembly mechanism includes two locking columns 202 which are respectively slidably arranged inside the two cavity blocks 106, and locking holes 204 are opened inside the two clamping plates 107. The two locking columns 202 are respectively plugged into the locking holes 204, and the upper ends of the two locking columns 202 are respectively provided with pull plates 201. The outer arc surfaces of the two pull plates 201 are provided with multiple evenly distributed anti-slip protrusions 205. Springs 203 are respectively provided between the two pull plates 201 and the cavity blocks 106, and the two springs 203 are respectively sleeved on the outer arc surfaces of the corresponding locking columns 202.

[0023] By placing the valve to be clamped on the support plate 108, and then controlling the control panel 103 to turn on the dual-axis motor 302, the output shaft drives the screw rods 301 on both sides to rotate. Since the thread directions of the screw rods 301 on both sides are opposite, the sliding plates 105 on both sides are driven to approach each other, and the valve is clamped through the clamping plate 107 inside the cavity block 106. The buffer pad 109 on the inner arc surface of the clamping plate 107 can prevent the valve from making hard contact with it, thereby preventing the outer surface of the valve from being clamped.

[0024] When it is necessary to clamp valves of different sizes or shapes, the locking column 202 is moved away from the locking hole 204 on the clamping plate 107 by pulling the pull plates 201 on both sides. Then the personnel can slide the clamping plate 107 out from the cavity block 106. At this time, the spring 203 is in a stretched state. Then the clamping plate 107 that is adapted to the size and shape of the clamped valve is slid into the cavity block 106. Then the pull plate 201 is released. At this time, the spring 203 contracts rapidly, so that the locking column 202 is inserted into the locking hole 204, thereby locking the clamping plate 107. Then, the control panel 103 is used to control the opening of the dual-axis motor 302 so that the replaced clamping plates 107 are moved toward each other to clamp the valve again. In the process of pulling the pull plate 201, the anti-slip protrusion 205 can prevent the human hand from slipping.

[0025] According to another embodiment of the present invention, Figure 1 As shown, two mounting holes 104 are provided inside the support plate 102 , and the clamping assembly can be quickly mounted on the valve production device through the mounting holes 104 on the support plate 102 , saving installation time.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
