Description

Technical Field

[0001] This utility model relates to the field of metal parts processing technology, specifically a clamping and positioning fixture for multi-size metal parts. Background Technology

[0002] Metal processing is the process of transforming raw metal materials into parts or products with specific shapes, sizes, and properties through various technological means. Machining fixtures are devices used to fix and position workpieces during metal processing to ensure the accuracy and stability of the machining process.

[0003] Publication No. CN219212375U discloses a positioning fixture for metal part processing. This device can support and limit the position of an "L"-shaped metal part by setting a pad, and the first adjustment mechanism can push the first support plate to move, thereby using the first and second support plates to support and clamp metal parts of different sizes. The second adjustment mechanism can adjust the height of the pad on one side of the second support plate, thereby supporting metal parts of different heights and making the top of the metal part more horizontal, which facilitates steps such as grinding and drilling. However, this patent still has the following problems in actual use:

[0004] The device supports and clamps metal parts of different sizes using a first support plate and a second support plate. The second adjustment mechanism can adjust the height of the pad on one side of the second support plate, thus supporting metal parts of different heights. However, the device is not capable of clamping disc-shaped metal parts. When workers fix workpieces such as brake discs, the small contact area between the circular metal part and the support plate may cause the circular metal part to shift during processing, which limits the workers' ability to use it.

[0005] A clamping and positioning fixture for multi-sized metal parts is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a clamping and positioning fixture for metal parts of various sizes, in order to solve the problem mentioned in the background art. Currently, metal parts of different sizes are supported and clamped by a first support plate and a second support plate. The second adjustment mechanism can adjust the height of the pad on one side of the second support plate, so that metal parts of different heights can be supported. However, this device is not capable of clamping disc-shaped metal parts. When the operator fixes workpieces such as brake discs, the small contact area between the circular metal part and the support plate may cause the circular metal part to shift during the processing.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a clamping and positioning fixture for multi-size metal parts, comprising a support frame, a worktable fixedly connected to the top of the support frame, and a base fixedly connected to the bottom of the support frame; an adjustment mechanism is provided between the worktable and the support frame, and movable components are symmetrically arranged at the bottom of the base;

[0008] The adjustment mechanism includes a circular box fixedly installed inside the workbench. The top of the workbench has symmetrically arranged grooves. A screw is rotatably connected between the grooves, the workbench, and the circular box. A rotating rod is rotatably connected between the circular box, the workbench, and the support frame. A turntable is fixedly connected to the top of the rotating rod, and teeth are welded to the top of the turntable. A first conical tooth is fixedly connected to the end of the screw near the circular box. A fixed box is fixedly connected to the inner top of the support frame. A drive rod is rotatably connected between the fixed box and the support frame. A second conical tooth is fixedly connected to the bottom of the rotating rod. A third conical tooth is fixedly connected to one end of the drive rod. A threaded block is threaded to the outside of the screw. A rotating shaft is fixedly connected to the top of the threaded block. A rotating plate is rotatably connected to the outside of the rotating shaft. A rubber block is fixedly connected to one side of the rotating plate, and an arc-shaped rubber pad is fixedly connected to the side of the rotating plate away from the rubber block.

[0009] Preferably, the rotating plate is symmetrically fixedly connected to a sliding box inside, and slots are symmetrically opened on the top of the worktable. A rod is slidably connected inside the sliding box, and a baffle is fixedly connected to the outside of the rod. A first retraction spring is sleeved on the outside of the rod, and a pull plate is fixedly connected between the tops of the rods. The bottom of the rod is inserted into the slot.

[0010] Preferably, the movable component includes a fixed sleeve, and the fixed sleeves are symmetrically fixedly connected to the inside of both ends of the base. A fixed block is inserted into the bottom inner side of the fixed sleeve, and a connecting plate is fixedly connected to the bottom of the fixed block. A universal wheel is rotatably connected to the bottom of the connecting plate. Fixed tubes are symmetrically fixedly connected to the inside of both sides of the fixed sleeve. A slider is slidably connected to the inside of one end of the fixed tube. A second retraction spring is fixedly connected between one side of the slider and the inside of the fixed tube. A protrusion is fixedly connected to the side of the slider away from the second retraction spring. Grooves are symmetrically opened on both sides of the fixed block, and the protrusion is inserted into the groove.

[0011] Preferably, the first conical tooth is engaged with the tooth, and the second conical tooth is engaged with the third conical tooth.

[0012] Preferably, the outer side of the threaded block is slidably connected to the inner side of the groove.

[0013] Preferably, the outer side of the baffle is slidably connected to the inside of the sliding box.

[0014] Preferably, the bottom of the rotating rod passes through the fixed box and is rotatably connected to the fixed box.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This clamping and positioning fixture for multi-sized metal parts specifically comprises the following: The operator rotates the drive rod, which drives the rotation of the third conical tooth; the rotation of the third conical tooth drives the rotation of the second conical tooth; the rotation of the rotating rod drives the rotation of the turntable; the meshing of the teeth drives the rotation of multiple sets of first conical teeth; the rotation of the screw drives the movement of the threaded block; the movement of the threaded block drives the movement of the rotating plate. At this time, the arc-shaped rubber pad presses and fixes the circular metal part externally. By rotating the rotating plate outside the rotating shaft, the four rubber blocks correspond to each other, achieving the effect of clamping the block-shaped metal part. This enables the rapid clamping and fixing of metal parts, and the operator... It can be quickly adjusted according to the shape of metal parts and can meet the fixing and processing effects of metal parts of various specifications, thus greatly improving the flexibility of the device during use and expanding its application range. When the operator inserts the fixing block into the bottom inner side of the fixing sleeve, the fixing block presses against the protruding block. At this time, the protruding block drives the slider to slide inside the fixing tube. The second contraction spring is deformed by the compression of the slider and quickly extends and resets, thus enabling multiple sets of protruding blocks to be inserted into the groove, thereby achieving the effect of quickly fixing and limiting the fixing block. This makes it easy for the operator to install and remove the casters, allowing the operator to choose to move or place the equipment according to the needs of equipment use, greatly improving the flexibility of the device during use.

[0016] 1. The operator rotates the drive rod, which in turn rotates the third conical tooth. This rotation drives the second conical tooth, which in turn rotates the rotating rod. The rotating rod then rotates the turntable, which in turn rotates multiple sets of teeth. The meshing of these teeth drives the rotation of multiple sets of first conical teeth. The rotation of the first conical teeth drives the screw, which in turn moves the threaded blocks. At this point, the four threaded blocks move along a convergent or unfolded trajectory. This movement of the threaded blocks moves the rotating plate, causing the arc-shaped rubber pads to press and fix the circular metal part. The arc-shaped rubber pads deform under this pressure. When the operator needs to clamp a square or rectangular metal part, they rotate the rotating plate outside the shaft, causing the four rubber blocks to align with each other, thus clamping the block-shaped metal part. This device enables rapid clamping and fixing of metal parts, allowing operators to quickly adjust according to the shape of the metal parts. It can also handle the fixing and processing of metal parts of various specifications, greatly improving the flexibility and applicability of the device and providing convenience for operators. By pulling the pull plate, the operator moves the insertion rod inside the sliding box. The movement of the insertion rod causes the baffle to move, at which point the first contraction spring is compressed and contracted. When the operator releases the pull plate, the return property of the first contraction spring allows the bottom of the insertion rod to be inserted into the slot, thereby achieving the effect of quickly fixing the position of the rotating plate. This also limits the rotation plate after the angle is adjusted, preventing the rotation plate from shifting during the clamping process, thus greatly improving the stability of the metal parts during fixing.

[0017] 2. When the worker inserts the fixing block into the bottom inner side of the fixing sleeve, the fixing block presses against the protruding block. The protruding block then drives the slider to slide inside the fixing tube. At this time, the second contraction spring is deformed by the pressure of the slider. When the fixing block is fully inserted into the fixing sleeve, the second contraction spring quickly extends and returns to its original position. This allows multiple sets of protruding blocks to be inserted into the groove, thereby achieving the effect of quickly fixing and limiting the fixing block. This facilitates the installation and removal of the casters by the worker, allowing the worker to choose to move or place the equipment according to the needs of equipment use. This greatly improves the flexibility of the device during use and brings convenience to the worker. Attached Figure Description

[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 1-6 The present invention provides a technical solution: a clamping and positioning fixture for metal parts of various sizes, including a support frame 1, a worktable 101 fixedly connected to the top of the support frame 1, and a base 102 fixedly connected to the bottom of the support frame 1; an adjustment mechanism 2 is provided between the worktable 101 and the support frame 1, and moving components 3 are symmetrically provided on the bottom of the base 102.

[0027] The adjustment mechanism 2 includes a circular box 201 fixedly installed inside the workbench 101. The top of the workbench 101 is symmetrically provided with sliding grooves 202. A screw 203 is rotatably connected between the sliding grooves 202, the workbench 101, and the circular box 201. A rotating rod 204 is rotatably connected between the circular box 201, the workbench 101, and the support frame 1. A turntable 205 is fixedly connected to the top of the rotating rod 204, and teeth 206 are welded to the top of the turntable 205. A first conical tooth 207 is fixedly connected to one end of the screw 203 near the circular box 201. A fixed box 208 is fixedly connected to the inner top of the support frame 1. The bottom of the rotating rod 204 passes through the fixed box 208 and is rotatably connected to it. A drive rod 209 is rotatably connected between the fixed box 208 and the support frame 1. A second conical tooth 210 is fixedly connected to the bottom of the rotating rod 204, and one end of the drive rod 209 is fixedly connected to... The device is equipped with a third conical tooth 211, a first conical tooth 207 meshing with a tooth 206, a second conical tooth 210 meshing with a third conical tooth 211, and a threaded block 212 threadedly connected to the external thread of the screw 203. The external threaded block 212 is slidably connected to the inner side of the slide groove 202. A rotating shaft 213 is fixedly connected to the top of the threaded block 212, and a rotating plate 214 is rotatably connected to the external side of the rotating shaft 213. A rubber block 215 is fixedly connected to one side of the rotating plate 214, and an arc-shaped rubber pad 216 is fixedly connected to the side of the rotating plate 214 away from the rubber block 215. This allows for quick clamping and fixing of metal parts, and enables workers to quickly adjust the device according to the shape of the metal parts. It can also meet the requirements for fixing and processing metal parts of various specifications, thus greatly improving the flexibility of the device during use, expanding its applicability, and providing convenience for workers during use.

[0028] The rotating plate 214 has symmetrically fixed sliding boxes 217 inside, and slots 218 are symmetrically opened on the top of the worktable 101. A rod 219 is slidably connected inside the sliding box 217, and a baffle 220 is fixedly connected to the outside of the rod 219. The outside of the baffle 220 is slidably connected to the inside of the sliding box 217. A first retraction spring 221 is sleeved on the outside of the rod 219, and a pull plate 222 is fixedly connected to the top of the rod 219. The bottom of the rod 219 is inserted into the slot 218. When the operator pulls the pull plate 222, the rod 219 moves in a sliding motion. The sliding mechanism inside the movable box 217 causes the insertion rod 219 to move, which in turn moves the baffle 220. At this time, the first contraction spring 221 is compressed and contracted. Then, by the worker releasing the pull plate 222, the first contraction spring 221 can be used to reset the bottom of the insertion rod 219 and the slot 218, thereby achieving the effect of quickly fixing the position of the rotating plate 214. This also limits the position of the rotating plate 214 after the angle has been adjusted, preventing the rotating plate 214 from shifting during the clamping process. This greatly improves the stability of the metal parts during fixing and brings practicality to the workers.

[0029] The movable component 3 includes a fixed sleeve 301, which is symmetrically fixedly connected to the inside of both ends of the base 102. A fixed block 302 is inserted into the inner bottom of the fixed sleeve 301, and a connecting plate 303 is fixedly connected to the bottom of the fixed block 302. A caster wheel 304 is rotatably connected to the bottom of the connecting plate 303. Fixed tubes 305 are symmetrically fixedly connected to the inside of both sides of the fixed sleeve 301. A slider 306 is slidably connected to the inside of one end of the fixed tube 305, and one side of the slider 306 is fixedly connected to the inside of the fixed tube 305. A second retraction spring 307 is connected, and a protrusion 308 is fixedly connected to the side of the slider 306 away from the second retraction spring 307. The two sides of the fixing block 302 are symmetrically provided with grooves 309, and the protrusion 308 is inserted into the groove 309. This can achieve the effect of quickly fixing and limiting the fixing block 302, which makes it easier for the staff to install and remove the caster 304. This allows the staff to choose to move or place the equipment according to the needs of the equipment, greatly improving the flexibility of the device and bringing convenience to the staff.

[0030] Working principle: Before using this clamping and positioning fixture for multi-sized metal parts, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 6As shown, when a worker places a metal part at the top center of the round box 201, the worker rotates the drive rod 209, causing the third conical tooth 211 to rotate. The rotation of the third conical tooth 211 causes the second conical tooth 210 to rotate. The rotation of the second conical tooth 210 causes the rotating rod 204 to rotate. The rotation of the rotating rod 204 causes the turntable 205 to rotate. The rotation of the turntable 205 causes multiple sets of teeth 206 to rotate. The rotation of the teeth 206 meshes and drives multiple sets of first conical teeth 207 to rotate. The rotation of screw 203 causes the screw to rotate, which in turn causes the threaded blocks 212 to move. At this time, the four threaded blocks 212 move along a convergent or unfolded trajectory. The movement of the threaded blocks 212 causes the rotating plate 214 to move. Meanwhile, the arc-shaped rubber pad 216 presses and fixes the circular metal part to the outside. The arc-shaped rubber pad 216 is deformed under pressure. When the operator needs to clamp a square or rectangular metal part, the operator rotates the rotating plate 214 outside the rotating shaft 213, causing the four rubber blocks 215 to... These components work in tandem to clamp block-shaped metal parts, enabling rapid clamping and fixing. Operators can quickly adjust the clamping mechanism according to the shape of the metal parts and accommodate various specifications, significantly improving the flexibility and applicability of the device. Pulling the pull plate 222 causes the insertion rod 219 to slide inside the sliding box 217. The movement of the insertion rod 219 moves the baffle 220, compressing the first contraction spring 221. Releasing the pull plate 222 allows the first contraction spring 221 to return to its original position, allowing the bottom of the insertion rod 219 to engage with the slot 218. This quickly fixes the position of the rotating plate 214, limiting its position and preventing displacement during clamping. This greatly improves the stability of the metal parts and enhances its practicality.

[0031] When the worker inserts the fixing block 302 into the bottom inner side of the fixing sleeve 301, the fixing block 302 presses against the protrusion 308. At this time, the protrusion 308 drives the slider 306 to slide inside the fixing tube 305. The second contraction spring 307 is deformed by the pressure of the slider 306. When the fixing block 302 is fully inserted into the fixing sleeve 301, the second contraction spring 307 quickly extends and resets, thereby enabling multiple sets of protrusions 308 to be inserted into the grooves 309. This achieves the effect of quickly fixing and limiting the fixing block 302, making it easier for the worker to install and remove the caster 304. This allows the worker to choose to move or place the equipment according to the needs of equipment use, greatly improving the flexibility of the device and bringing convenience to the worker.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
