Description

Technical Field

[0001] This utility model belongs to the field of machining fixture technology, and in particular relates to an external pre-adjustment machining fixture. Background Technology

[0002] In the field of modern machining, machining accuracy and efficiency have always been the core goals. Traditional machining fixtures have gradually revealed some limitations during use. For example, when the fixture needs to clamp and fix the workpiece, the operator usually needs to adjust multiple clamping plates in sequence. This not only greatly reduces work efficiency, but also causes the workpiece to be clamped eccentrically, which affects the subsequent processing of the workpiece. At the same time, most fixtures are difficult to clamp and fix workpieces of different diameters, reducing the versatility of the equipment. Therefore, an external pre-adjustment machining fixture is proposed. Utility Model Content

[0003] The purpose of this utility model is to provide an external pre-adjustment machining fixture. By setting a fixing part, specifically, rotating a knob clockwise drives a double-sided gear to rotate. At this time, the rotation of several gears through the double-sided gear will cause several clamping plates to move closer together. When the clamping plates move closer together, they will clamp and fix the workpiece. This solves the problem that when the fixture needs to clamp and fix the workpiece, the operator usually needs to adjust multiple clamping plates one by one. This not only greatly reduces the work efficiency, but also causes the workpiece to be clamped eccentrically, thus affecting the subsequent processing of the workpiece. In addition, most fixtures are difficult to clamp and fix workpieces of different diameters, reducing the versatility of the equipment.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to an external pre-adjustment machining fixture, including a mounting plate. The mounting plate has several mounting holes on its front side and an opening at the center of its front side. It also includes:

[0006] The fixing part, which is disposed on the front side of the mounting plate, serves to fix the workpiece; and

[0007] The reinforcing part is connected to the fixing part and serves to reinforce the workpiece.

[0008] Before the equipment is used, the mounting plate is installed through several mounting holes.

[0009] Furthermore, the fixing part includes a driving assembly, which is disposed on the right side of the front of the mounting plate, and the driving assembly provides power output for clamping the workpiece;

[0010] A clamping assembly is connected to the front of the mounting plate, and the clamping assembly is driven by a driving assembly to clamp and fix the workpiece.

[0011] The clamping component improves the clamping effect compared to traditional clamping methods by using a synchronous and fixed-point clamping method.

[0012] Furthermore, the reinforcing part includes an anti-loosening component, which is connected to the right side of the front of the mounting plate and serves to limit the position of the clamping component.

[0013] In particular, by setting anti-loosening components to limit the clamping components, the workpiece is reduced from shaking during processing, thereby improving the processing accuracy.

[0014] Furthermore, the drive assembly includes a knob, a rotating shaft is welded inside the knob, a drive gear is connected to the end of the rotating shaft away from the knob, and a double-sided gear is meshed with the outer surface of the drive gear.

[0015] The drive assembly drives the clamping assembly to move through the action of a double-sided gear, thereby achieving the clamping of the workpiece.

[0016] Furthermore, the clamping assembly includes a clamping plate, a gear is connected to the side of the clamping plate, the gear is rotatably connected to the inside via a pin, a fixing ring one is welded to the front of the mounting plate, a fixing ring two is provided in the inner ring of the fixing ring one, and several limiting grooves are opened inside the fixing ring one and the fixing ring two.

[0017] The clamping plates and gears are arranged in multiples. The back of the second fixing ring is welded to the front of the mounting plate. The double-sided gear is set inside the first fixing ring. The rotating shaft passes through the first fixing ring and extends into the interior.

[0018] Furthermore, the anti-loosening component includes a fixing plate, the back of which is welded to the right side of the front of the mounting plate, a threaded rod is threadedly connected inside the fixing plate, a second knob is provided on the right side of the fixing plate, the inside of the second knob is welded to the outer surface of the threaded rod, a second locking ring is rotatably connected to the end of the threaded rod away from the second knob, and a limit sleeve is provided on the side of the fixing plate away from the second knob.

[0019] Furthermore, a locking ring is provided on the left side inside the limiting sleeve. The back of the locking ring is welded to the front of the fixing ring. The right side of the locking ring is in contact with the outer surface of the rotating shaft. The side of the locking ring near the rotating shaft is in contact with the side of the locking ring away from the threaded rod. The back of the limiting sleeve is welded to the front of the mounting plate. The inside of the limiting sleeve is rotatably connected to the outer surface of the rotating shaft.

[0020] Among them, two limiting rods are welded on the side of the second locking ring away from the first locking ring. The two limiting rods pass through the limiting sleeve, and the outer surfaces of the two limiting rods are slidably connected to the inside of the fixing plate.

[0021] This utility model has the following beneficial effects:

[0022] 1. This utility model features a fixing part. Specifically, rotating the knob clockwise drives the double-sided gear to rotate. At this time, the rotation of the double-sided gear causes several clamping plates to move closer together. When the clamping plates move closer together, they clamp and fix the workpiece. This method can clamp and fix workpieces of different diameters. Moreover, this clamping method is synchronous, which not only improves the clamping efficiency of the workpiece, but also reduces the situation of eccentric clamping of the workpiece, making it easier for subsequent processing of the workpiece.

[0023] 2. This utility model incorporates a reinforcing component. Specifically, rotating the second knob clockwise causes the threaded rod to rotate. As the threaded rod rotates, it moves the second locking ring closer to the rotating shaft. Simultaneously, the movement of the second locking ring causes the two limiting rods to slide inside the limiting sleeve. When the second locking ring aligns and clamps with the first locking ring, it locks the rotating shaft, reducing the possibility of the drive gear rotating due to external force vibration. This strengthens the equipment's grip on the workpiece, reduces workpiece displacement during processing, and significantly improves the accuracy of workpiece processing.

[0024] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0033] 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.

[0034] Please see Figures 1-5 As shown, this utility model is an external pre-adjustment machining fixture, including a mounting plate 111, a plurality of mounting holes 112 on the front side of the mounting plate 111, and an opening 113 at the center of the front side of the mounting plate 111, and also including:

[0035] Fixing part 2 is provided on the front side of mounting plate 111, and fixing part 2 serves to fix the workpiece; and

[0036] The reinforcing part 3 is connected to the fixing part 2, and the reinforcing part 3 serves to reinforce the workpiece.

[0037] Before the equipment is used, the mounting plate 111 is installed through a number of mounting holes 112.

[0038] The fixing part 2 includes a drive assembly 21, which is disposed on the right side of the front of the mounting plate 111. The drive assembly 21 provides power output for clamping the workpiece.

[0039] The clamping assembly 22 is connected to the front of the mounting plate 111. The clamping assembly 22 is driven by the drive assembly 21 to clamp and fix the workpiece.

[0040] The clamping assembly 22 improves the clamping effect compared to traditional clamping methods by using synchronous and fixed-point clamping. Rotating the knob 211 clockwise drives the double-sided gear 214 to rotate via the drive gear 213. At this time, the rotation of several gears 222 via the double-sided gear 214 will cause several clamping plates 221 to move closer to each other. When the clamping plates 221 move closer to each other, they will clamp and fix the workpiece. At the same time, workpieces of different diameters can be clamped and fixed. Moreover, this clamping method adopts synchronization, which not only improves the clamping efficiency of the workpiece, but also reduces the situation of eccentric clamping of the workpiece, which facilitates the subsequent processing of the workpiece.

[0041] The reinforcement part 3 includes an anti-loosening component 31, which is connected to the right side of the front of the mounting plate 111. The anti-loosening component 31 serves to limit the position of the clamping component 22.

[0042] The anti-loosening component 31 limits the clamping component 22, reducing workpiece wobbling during processing and improving processing accuracy. While rotating knob 211, pull knob 315 is pulled to compress spring 317. Spring 317, limited by the inner wall of the limiting frame 311, contracts and stores force. After several clamping plates 221 clamp and fix the workpiece, the operator releases pull knob 315. Spring 317 then generates a certain rebound force, driving the limiting rod 316 to reset. The limiting rod 316 then inserts into the limiting hole 314 to limit and fix the limiting sleeve 313, reducing the rotation of the drive gear 213 due to external vibration. This strengthens the equipment's grip on the workpiece, reduces workpiece deviation during processing, and significantly improves processing accuracy.

[0043] Drive assembly 21 includes a knob 211, a rotating shaft 212 is welded inside the knob 211, a drive gear 213 is connected to the end of the rotating shaft 212 away from the knob 211, and a double-sided gear 214 is meshed on the outer surface of the drive gear 213.

[0044] The drive assembly 21 drives the clamping assembly 22 to move through the action of the double-sided gear 214, thereby achieving the clamping of the workpiece.

[0045] The clamping assembly 22 includes a clamping plate 221. A gear 222 is connected to the side of the clamping plate 221. The gear 222 is rotatably connected to the inside of the mounting plate 111 through a pin. A fixing ring 223 is welded to the front of the mounting plate 111. A fixing ring 224 is provided in the inner ring of the fixing ring 223. Several limiting grooves 225 are opened inside both the fixing ring 223 and the fixing ring 224.

[0046] Among them, there are several clamping plates 221 and gears 222. The back of the second fixing ring 224 is welded to the front of the mounting plate 111. The double-sided gear 214 is set inside the first fixing ring 223. The rotating shaft 212 passes through the first fixing ring 223 and extends into the interior.

[0047] The anti-loosening component 31 includes a fixing plate 311. The back of the fixing plate 311 is welded to the right side of the front of the mounting plate 111. A threaded rod 316 is threadedly connected inside the fixing plate 311. A knob 317 is provided on the right side of the fixing plate 311. The inside of the knob 317 is welded to the outer surface of the threaded rod 316. A locking ring 314 is rotatably connected to the end of the threaded rod 316 away from the knob 317. A limit sleeve 312 is provided on the side of the fixing plate 311 away from the knob 317.

[0048] A locking ring 313 is provided on the left side inside the limiting sleeve 312. The back of the locking ring 313 is welded to the front of the fixing ring 223. The right side of the locking ring 313 is in contact with the outer surface of the rotating shaft 212. The side of the locking ring 313 near the rotating shaft 212 is in contact with the side of the locking ring 314 away from the threaded rod 316. The back of the limiting sleeve 312 is welded to the front of the mounting plate 111. The inside of the limiting sleeve 312 is rotatably connected to the outer surface of the rotating shaft 212.

[0049] Two limiting rods 315 are welded to the side of the second locking ring 314 away from the first locking ring 313. The two limiting rods 315 pass through the limiting sleeve 312, and the outer surfaces of the two limiting rods 315 are slidably connected to the inside of the fixing plate 311. Rotating the knob 317 clockwise causes the threaded rod 316 to rotate. When the threaded rod 316 rotates, it causes the second locking ring 314 to move closer to the rotating shaft 212. At the same time, when the second locking ring 314 moves, it causes the two limiting rods 315 to slide inside the limiting sleeve 312. When the second locking ring 314 is aligned and clamped with the first locking ring 313, it locks the rotating shaft 212, reducing the rotation of the drive gear 213 due to external vibration. This strengthens the equipment's grip on the workpiece and reduces the possibility of workpiece displacement during processing, thereby significantly improving the accuracy of workpiece processing.

[0050] A specific application of this embodiment is as follows: In use, the mounting plate 111 is first installed in a specific position through several mounting holes 112. Then, the workpiece to be processed is passed through the opening 113. The operator then rotates the knob 211 clockwise to drive the rotating shaft 212 to rotate. During the rotation of the rotating shaft 212, the driving gear 213 will also rotate. When the driving gear 213 rotates, it will drive the double-sided gear 214 to rotate. Simultaneously, the rotating shaft 212 will rotate inside the fixing ring 223. At this time, several gears 222 will also rotate through the double-sided gear 214. The mechanism will rotate, and during the rotation of several gears 222, several clamping plates 221 will move closer to each other. When the clamping plates 221 move closer to each other, they will slide inside the limiting groove 225. By setting the limiting groove 225, a certain limiting property is provided for the movement trajectory of the clamping plates 221. When the clamping plates 221 move closer to each other, they will clamp and fix the workpiece. At the same time, workpieces of different diameters can be clamped and fixed. Moreover, this clamping method adopts synchronization, which not only improves the clamping efficiency of the workpiece, but also reduces the situation of eccentric clamping of the workpiece, which facilitates the subsequent processing of the workpiece.

[0051] After several clamping plates 221 clamp and fix the workpiece, the knob 317 is turned clockwise to drive the threaded rod 316 to rotate. When the threaded rod 316 rotates, it will drive the locking ring 314 to move closer to the rotating shaft 212. At the same time, when the locking ring 314 moves, it will drive the two limiting rods 315 to slide inside the limiting sleeve 312. The two limiting rods 315 provide a certain degree of limitation for the movement trajectory of the locking ring 314. When the locking ring 314 is aligned and clamped with the locking ring 313, it will lock the rotating shaft 212, reducing the possibility of the drive gear 213 rotating due to external force vibration. This strengthens the firmness of the equipment in clamping the workpiece and reduces the possibility of the workpiece shifting during processing, thereby greatly improving the accuracy of workpiece processing.
