Description

Technical Field

[0001] This utility model relates to the field of butterfly valve plate positioning, specifically a rapid positioning device for butterfly valve plate laser marking. Background Technology

[0002] A butterfly valve, also known as a flap valve, is a simple regulating valve. The valve plate (also called the valve disc or butterfly plate), the closing element of the butterfly valve, is usually disc-shaped and rotates around the valve shaft to open and close. It mainly functions as a shut-off and throttling device in pipelines. To facilitate the use of the valve plate, laser marking is required. To ensure stability during the marking process, the valve plate needs to be positioned, necessitating the use of a positioning device. However, existing positioning devices are inconvenient for positioning valve plates of various sizes, affecting their versatility. Therefore, it is necessary to provide a positioning device that can quickly position valve plates of different sizes, enhancing its versatility. Furthermore, the overall stability of existing positioning devices is insufficient, affecting their safety. Therefore, it is necessary to provide a positioning device that can reduce vibration and enhance safety. Utility Model Content

[0003] This invention provides a rapid positioning device for laser marking of butterfly valve plates, aiming to solve the problem that existing positioning devices are not convenient for stably clamping valve plates of different sizes.

[0004] To achieve the above objectives, this utility model provides a rapid positioning device for laser marking on a butterfly valve plate, comprising a buffer assembly and a positioning assembly;

[0005] The buffer assembly includes a mounting plate, with three first legs fixedly connected to the lower end of the mounting plate. Second legs are sleeved on the side surfaces of the three first legs. Two dampers are detachably installed at the lower ends of the second legs. Buffer springs are sleeved on the side surfaces of the two dampers. A receiving block is detachably installed at the upper end of the mounting plate. A magnet is installed inside the receiving block. A valve plate body is provided at the upper end of the receiving block. Several guide grooves are equidistantly opened on the surface of the mounting plate.

[0006] A positioning assembly includes a turntable mounted on the lower end of a mounting plate. Several transmission rods are hinged to the upper end of the turntable, and guide blocks are hinged to the ends of the transmission rods. A clamping piece is fixedly connected to the upper end of the guide block, and a transmission mechanism is mounted on the lower end of the turntable.

[0007] Furthermore, the transmission mechanism includes a first bevel gear mounted on the lower end of the turntable, a servo motor mounted on the lower end of the mounting plate, and a second bevel gear connected to the output end of the servo motor, with the second bevel gear and the first bevel gear meshing together.

[0008] Furthermore, a limiting groove is formed on the surface of the mounting plate, and a limiting shaft is fixedly connected to the lower end of the receiving block, with the limiting shaft inserted into the inside of the limiting groove.

[0009] Furthermore, the lower end of the first leg has two screw holes, and the upper end of the damper is fixedly connected with a bolt, which is threaded into the inside of the screw holes.

[0010] Furthermore, sliding grooves are provided on both sides of the guide groove, and an installation groove is provided at the upper end of the receiving block, with the magnet block installed inside the installation groove.

[0011] Furthermore, positioning grooves are provided on both sides of the first leg, and positioning strips are fixedly connected to both sides of the inner wall of the second leg, with the positioning strips slidably connected inside the positioning grooves.

[0012] Furthermore, sliders are fixedly connected to both sides of the lower end of the guide block, and the sliders are slidably connected inside the slide groove. Several hinge shafts are fixedly connected to the upper end of the turntable, and the hinge shafts are hinged inside the transmission rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. When positioning butterfly valve bodies of different sizes, valve plates of different sizes are first placed on the upper end of the receiving block. The valve plates are magnetically connected to the magnetic block, which initially improves the positioning stability of the valve plates. Then, the transmission mechanism is started to rotate the turntable clockwise or counterclockwise, thereby controlling several transmission rods to pull or support the guide block, so that the guide block moves back and forth along the guide groove. This allows the distance between several clamping plates to be adjusted, thereby clamping valve plates of different sizes. Compared with the positioning device in the prior art, this utility model can facilitate the rapid positioning of valve plates of different sizes through the cooperation of the above structures, thereby enhancing the versatility of the positioning device.

[0015] 2. When positioning and clamping the valve plate body, the mounting plate is subjected to force and transmits the pressure to several first legs. The several first legs descend along the second legs. The damper and buffer spring can reduce the vibration frequency of the positioning device, thereby facilitating the shock absorption effect of the positioning device. At the same time, the three first legs and the second legs can significantly improve the overall stability of the mounting plate. Compared with the positioning device in the prior art, the present invention can significantly improve the stability of the positioning device through the above-mentioned structure, thereby improving the safety of use.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 5 This utility model provides a rapid positioning device for laser marking on a butterfly valve plate, including a buffer assembly 100 and a positioning assembly 200;

[0027] The buffer assembly 100 includes a mounting plate 101. Three first legs 102 are fixedly connected to the lower end of the mounting plate 101. Second legs 103 are sleeved on the side surfaces of the three first legs 102. Two dampers 104 are detachably installed at the lower end of the second legs 103. Buffer springs 105 are sleeved on the side surfaces of the two dampers 104. A receiving block 106 is detachably installed at the upper end of the mounting plate 101. A magnet block 107 is installed inside the receiving block 106. A valve plate body 108 is provided at the upper end of the receiving block 106. Several guide grooves 109 are equidistantly opened on the surface of the mounting plate 101.

[0028] The positioning component 200 includes a turntable 201 mounted on the lower end of the mounting plate 101. Several transmission rods 202 are hinged to the upper end of the turntable 201. Guide blocks 203 are hinged to the ends of the transmission rods 202. Clamping pieces 204 are fixedly connected to the upper ends of the guide blocks 203. A transmission mechanism 205 is mounted on the lower end of the turntable 201.

[0029] In one specific embodiment, the buffer component 100, in conjunction with the positioning component 200, not only facilitates the rapid clamping and positioning of valve plate bodies 108 of different sizes, thereby enhancing the versatility of the positioning device, but also, through the cooperation of the above structures, provides a shock-absorbing effect for the positioning device, thus ensuring stability and enhancing the safety of the positioning device. In use, valve plate bodies 108 of different sizes are first placed on the upper end of the receiving block 106. The magnetic connection between the magnet block 107 and the valve plate body 108 initially improves the positioning stability of the valve plate body 108. Then, the transmission mechanism 205 is activated, causing the turntable 201 to rotate clockwise or counterclockwise, thereby... The system can control several transmission rods 202 to pull or support the guide block 203, thereby controlling the guide block 203 to reciprocate along the guide groove 109. This allows for adjustment of the distance between several clamping plates 204, enabling the clamping of valve plate bodies 108 of different sizes and enhancing the versatility of the positioning device. When the positioning device is in use, the mounting plate 101 is subjected to force and transmits the pressure to several first legs 102. The several first legs 102 descend along the second legs 103. At this time, the damper 104, in conjunction with the buffer spring 105, can reduce the vibration frequency of the positioning device, thereby achieving a shock absorption effect and improving the safety of the positioning device.

[0030] Please see Figure 4 and Figure 5 The transmission mechanism 205 includes a first bevel gear 2051 mounted on the lower end of the turntable 201, a servo motor 2052 mounted on the lower end of the mounting plate 101, and a second bevel gear 2053 connected to the output end of the servo motor 2052. The second bevel gear 2053 and the first bevel gear 2051 are meshed together.

[0031] In one specific embodiment, the servo motor 2052 drives the second bevel gear 2053 to rotate, thereby driving the first bevel gear 2051 and its upper turntable 201 to rotate, so as to control the transmission rod 202 to move the guide block 203, thereby enabling the valve plate body 108 of different sizes to be clamped and positioned.

[0032] Please see Figure 2 and Figure 3 A limiting groove 111 is provided on the surface of the mounting plate 101, and a limiting shaft 112 is fixedly connected to the lower end of the receiving block 106. The limiting shaft 112 is inserted into the inside of the limiting groove 111.

[0033] In one specific embodiment, the limiting shaft 112 is inserted into the limiting groove 111, thereby improving the connection stability and ease of assembly and disassembly between the receiving block 106 and the mounting plate 101.

[0034] Please see Figure 2 and Figure 3 The lower end of the first leg 102 has two screw holes 121, and the upper end of the damper 104 is fixedly connected with a bolt 122, which is threaded into the inside of the screw holes 121.

[0035] In one specific embodiment, the bolt 122 is threaded inside the bolt hole 121, which can enhance the connection strength between the damper 104 and the first leg 102. At the same time, the damper 104 and the first leg 102 can be disassembled by removing the bolt 122.

[0036] Please see Figure 2 and Figure 3 The guide groove 109 has sliding grooves 131 on both sides, and the receiving block 106 has an installation groove 132 at the upper end, and the magnet block 107 is installed inside the installation groove 132.

[0037] In one specific embodiment, the mounting groove 132 can improve the stability of the magnet 107 installed in the receiving block 106.

[0038] Please see Figure 2 and Figure 3 The first leg 102 has positioning grooves 141 on both sides, and the second leg 103 has positioning strips 142 fixedly connected to both sides of its inner wall. The positioning strips 142 are slidably connected inside the positioning grooves 141.

[0039] In one specific embodiment, the positioning bar 142 is slidably connected inside the positioning groove 141. When the first leg 102 descends along the second leg 103, the lifting stability can be improved, and the safety of the positioning device can be further improved.

[0040] Please see Figure 4 and Figure 5Both sides of the lower end of the guide block 203 are fixedly connected to sliders 211, which are slidably connected inside the slide groove 131. Several hinge shafts 212 are fixedly connected to the upper end of the turntable 201, and the hinge shafts 212 are hinged inside the transmission rod 202.

[0041] In one specific embodiment, the hinge shaft 212 and the transmission rod 202 are hinged to each other, thereby improving the smoothness of the rotation of the transmission rod 202 when the turntable 201 rotates.

[0042] Working principle: In use, valve plate bodies 108 of different sizes are first placed on the upper end of the receiving block 106. They are magnetically connected to the valve plate bodies 108 by the magnet 107, which initially improves the positioning stability of the valve plate bodies 108. Then, the transmission mechanism 205 is started to rotate the turntable 201 clockwise or counterclockwise, which controls several transmission rods 202 to pull or support the guide block 203. Thus, the guide block 203 is controlled to reciprocate along the guide groove 109, which allows the distance between several clamping plates 204 to be adjusted so as to clamp valve plate bodies 108 of different sizes, thereby enhancing the versatility of the positioning device. When the positioning device is in use, the mounting plate 101 is subjected to force and transmits the pressure to several first legs 102. Several first legs 102 descend along the second legs 103. The damper 104 and the buffer spring 105 can reduce the vibration frequency of the positioning device, thereby reducing the vibration of the positioning device and improving the safety of the positioning device.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
