Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a fixture for grinding irregular surfaces of valves. Background Technology

[0002] Valves are generally composed of parts such as valve bodies and valve discs. The two sides of a valve are usually irregularly shaped. After initial forming, these irregularly shaped surfaces typically need to be ground. During grinding, clamps are used to limit and fix the valve, preventing displacement. A valve irregularly shaped surface grinding clamp is a tool used to fix and support the valve for grinding. Using a clamp ensures the stability and precision of the valve during grinding, thereby improving work efficiency and processing quality. However, commonly available valve irregularly shaped surface grinding clamps, after repeated contact between the clamping force structure and the valve, are prone to wear. Replacement is cumbersome, requiring the sequential loosening of bolts, affecting maintenance or replacement efficiency. Furthermore, the grinding powder collected during grinding is easily agitated and released into the air by the grinding force, potentially affecting worker health. Utility Model Content

[0003] This disclosure relates to a valve irregular surface grinding fixture. During the grinding process, the dust generated by grinding falls directly into the collection structure and is collected between the partition structures. When grinding is performed again, the partition structures block the wind force and limit the fluctuation and turbulence of the dust. At the same time, the flip plates are directly on both sides of the collection structure to block the dust, preventing the dust from being pushed and turbulent by the grinding force, and preventing the dust from spreading into the air and being inhaled by workers, thus affecting their health.

[0004] In a first aspect, this disclosure provides a valve profile grinding fixture, specifically comprising: a fixture body; the fixture body is an electrically driven clamping structure, the fixture body has a screw inside, the screw has symmetrically arranged threads at both ends on the outside, a moving component is installed inside the fixture body through the screw and a crossbar, the moving component is connected to a clamping head through a splicing groove and a connecting head assembly, a fixing rod assembly is slidably installed on the outer end of the clamping head through an outer rod assembly and a guide hole, the fixing rod assembly has a groove on each side of its outer end, and the bottom end of the fixing rod assembly is inserted into the moving component; a collecting structure; the collecting structure is embedded in the bottom of the fixture body, the collecting structure is a rectangular structure with an open top, the collecting structure has a uniformly arranged partition structure fixed inside through an inner plate, the partition structure is vertically arranged felt, the top two sides of the partition structure are inclined structures, and the inside two sides of the collecting structure have freely flip-over plates installed through connecting shafts.

[0005] In at least some embodiments, the clamp body has three internal components fixed inside. The internal components are triangular in structure and have gaps between them. A screw controls the movement of a moving assembly to clamp the clamp via a thread. The top inner side of the moving assembly has two splicing grooves with a T-shaped structure. Connecting head assemblies are slidably inserted into the splicing grooves, and the two connecting head assemblies are fixed to the bottom of the clamping head. An outer rod assembly is fixed outside the clamping head. The outer rod assembly has two guide holes through it. A fixed rod assembly is inserted into the guide holes and can be freely pulled out. A guide block is provided above the guide holes and is embedded in the groove.

[0006] In at least some embodiments, a guide rod is provided on each side of the collecting structure, the guide rod is embedded in the interior of the clamp body for guiding and pulling, and a freely rotatable rotating structure is provided at the bottom corner of the collecting structure; an inner plate is glued to the bottom of the collecting structure, the inner plate is made of felt material, a partition structure is fixed on the top of the inner plate, connecting shafts are inserted into both sides of the collecting structure, the connecting shafts are installed by coil springs, and the connecting shafts and the flip plate are continuously controlled in an upright state by the coil springs; a baffle structure is fixed on each side of the flip plate, and an inclined guide is provided at the top of the flip plate.

[0007] This utility model provides a valve irregular surface grinding fixture, which has the following beneficial effects:

[0008] If the inner side of the clamping head, which is in contact with the valve, becomes worn after multiple uses, affecting the clamping effect, the fixing rod assembly can be pulled up directly. This allows the fixing rod assembly to detach from the inside of the moving assembly, releasing the lateral fixation of the clamping head. Then, the clamping head can be pulled laterally to allow the connecting head assembly to slide out of the splicing groove, making it easy to disassemble and replace the clamping head and improving maintenance efficiency.

[0009] During the grinding process, the dust generated falls directly into the collection structure and is collected between the baffles. When grinding is performed again, the baffles block the wind and limit the dust from rising and falling. Meanwhile, the flip plates are located on both sides of the collection structure to block the dust, preventing it from being pushed and swirling by the grinding force and from spreading into the air, which could be inhaled by workers and affect their health.

[0023] Example 1: Please refer to Figures 1 to 6 :

[0024] This utility model proposes a valve irregular surface grinding fixture, including: a fixture body 1; the fixture body 1 is an electrically driven clamping structure, the fixture body 1 has a screw inside, and the screw has threads symmetrically arranged at both ends on the outside; a moving assembly 102 is installed inside the fixture body 1 through the screw and a crossbar; the moving assembly 102 is connected to a clamping head 105 through a splicing groove 103 and a connecting head assembly 104; a fixing rod assembly 108 is slidably installed on the outer end of the clamping head 105 through an outer rod assembly 106 and a guide hole 107; the U-shaped fixing rod assembly 108 has a groove on each side of its outer end; the bottom end of the fixing rod assembly 108 is inserted into the interior of the moving assembly 102, so that the clamping head 105 is connected to the splicing groove 103 through the connecting head assembly 104, so that the clamping head... The clamping head 105 is securely fixed above the moving component 102 and can also be easily pulled out, allowing the clamping head 105 to be moved laterally for disassembly, facilitating replacement or maintenance; Collection structure 2; The collection structure 2 is embedded in the bottom of the clamp body 1. The collection structure 2 is a rectangular structure with an open top. Inside the collection structure 2, evenly arranged partition structures 204 are fixed through the inner plate 203. The partition structures 204 are vertically arranged felt, and the top two sides of the partition structures 204 are inclined structures. Inside the collection structure 2, the two sides are connected by a connecting shaft 205 and a freely flipping plate 206 is installed, allowing the powder to fall between the partition structures 204. The partition structures 204 and the flipping plate 206 are subjected to force together, blocking the powder and preventing the powder from spreading into the air.

[0025] In this embodiment of the disclosure, such as Figure 3 and Figure 4 As shown, the clamp body 1 has three internal components 101 fixed inside. Each internal component 101 has a triangular structure, controlling the powder's flow and displacement, while simultaneously controlling the movement of the moving assembly 102. Gaps exist between the internal components 101, allowing powder to flow downwards and into the collection structure 2 for collection. A screw controls the movement and clamping of the moving assembly 102 via threads. Two T-shaped splicing grooves 103 are located on the inner side of the top of the moving assembly 102. Connecting head assemblies 104 are slidably inserted into the splicing grooves 103, facilitating easy installation and use of the connecting head assemblies 104 and clamping heads 105 together. The two connecting head assemblies 104 are fixed... The clamping head 105 is fixed at the bottom. The inner side of the clamping head 105 is provided with a telescopic round rod, which is used to contact and fix with the outside of the valve. An outer rod assembly 106 is fixed to the outside of the clamping head 105. Two guide holes 107 are opened through the inside of the outer rod assembly 106. The fixing rod assembly 108 is inserted into the inside of the guide holes 107 and can be pulled out freely. A guide block is provided above the inside of the guide holes 107. The guide block is embedded in the inside of the groove, so that the fixing rod assembly 108 can be pulled up and down freely, avoiding excessive pulling and removal of the fixing rod assembly 108. This allows the fixing rod assembly 108 to securely connect the clamping head 105 and the moving assembly 102 together for use.

[0026] In this embodiment of the disclosure, such as Figure 5 and Figure 6 As shown, a guide rod 201 is provided on each side of the collecting structure 2. The guide rod 201 is embedded inside the clamp body 1 to guide and pull the collecting structure 2, allowing it to be pulled out freely. A rotating structure 202 that can be freely rotated is provided at the bottom corner of the collecting structure 2, so that the bottom of the collecting structure 2 contacts the placement surface, allowing the collecting structure 2 to be pulled out smoothly. An inner plate 203 is glued to the bottom of the collecting structure 2. The inner plate 203 is made of felt material, which can help absorb powder. A partition structure 204 is fixed to the top of the inner plate 203. The collecting structure 2 has connecting shafts 205 inserted on both sides. The connecting shafts 205 are installed by coil springs. The connecting shafts 205 and the flip plate 206 are continuously controlled in an upright state by the coil springs, so that the flip plate 206 can be freely flipped and used. After the flip plate 206 is flipped, the collecting structure 2 can be inserted into the bottom of the clamp body 1. A baffle structure 207 is fixed on each side of the flip plate 206 to help block the powder diffusion. The top of the flip plate 206 is provided with an inclined guide 208 to control the powder to fall and be collected.

[0027] The working principle of this embodiment is as follows: First, the fixture body 1 is installed and fixed. Then, the collecting structure 2 is installed at the bottom of the fixture body 1. The flipping plate 206 and connecting shaft 205 are flipped using a coil spring, pushing the collecting structure 2 into the bottom of the fixture body 1, ensuring a stable installation. Then, the flipping plate 206 automatically flips and stands upright under the action of the coil spring. Next, the valve to be ground is placed between the two clamping heads 105. The screw is then rotated, driving the clamping heads 105 to displace under force, clamping and fixing the valve. The irregular surface of the valve is polished, and the polishing powder falls directly into the inside of the collection structure 2, between the partition structures 204. The partition structures 204 and the flip plate 206 block the powder and prevent the polishing force from stirring the powder. When wear occurs after the inner side of the clamping head 105 has been clamped and fixed multiple times, the fixing rod assembly 108 can be pulled up to control the lateral displacement of the clamping head 105, so that the connector assembly 104 can be disengaged from the inside of the splicing groove 103, making it easy to disassemble and replace the clamping head 105 and improve the efficiency of replacement and maintenance.
