Description

Technical Field

[0001] This utility model relates to the field of machining fixture technology, and in particular to a thin-walled bracket machining fixture with anti-slip clamping. Background Technology

[0002] In the field of machining small precision parts for machine tools, thin-walled brackets are used as key structural components in aerospace, medical devices and high-end electronic equipment. These parts have significant advantages such as light weight and material saving. These thin-walled brackets are usually made of lightweight metals such as aluminum alloy and magnesium alloy, and machining fixtures are required during their machining process.

[0003] Currently, most existing thin-walled support processing fixtures achieve their effects using the following technologies;

[0004] Mechanical structure technology: It adopts a multi-point uniform clamping structure, which disperses pressure through multiple jaws or pressure plates to reduce local stress concentration; the elastic support structure uses elastic elements to adapt to deformation and buffer the clamping force; the vacuum adsorption structure uses negative pressure to adsorb the workpiece onto the fixture surface, which is suitable for flat workpieces, and can clamp quickly and avoid deformation.

[0005] Materials application technology: Soft materials such as silicone and polyurethane are used as pads at the contact points between the fixture and the workpiece to increase the contact area and prevent pinching injuries; the main body of the fixture is made of high-rigidity materials such as alloy steel and hard aluminum alloy to ensure that it does not deform and to ensure stable clamping.

[0006] Control technology: The clamping force is precisely controlled by a hydraulic or pneumatic system, and the pressure is set according to the characteristics of the workpiece; the clamping mechanism is driven by a servo motor to achieve precise position and force control, which is conducive to the rapid switching of processing of workpieces of various specifications.

[0007] Positioning technologies: Pin positioning achieves high-precision positioning by inserting pins into pin holes, and is suitable for workpieces with regular shapes and positioning holes; Datum surface positioning uses the datum surface of the fixture to fit against a specific surface of the workpiece for positioning, and is often used in conjunction with clamping devices to prevent displacement.

[0008] Currently, existing technical solutions have been found to have at least the following technical problems during implementation;

[0009] Currently, most existing thin-walled bracket processing fixtures use rubber pads as anti-slip components. However, the rubber pads of existing fixtures are mostly not easy to replace. After long-term use, the rubber pads will wear down, which will affect their anti-slip performance. Therefore, the rubber pads need to be replaced frequently. Rubber pads that are not easy to replace (e.g., glued, threaded, etc.) affect the use of the fixture. At the same time, most existing fixtures do not have a reminder structure to remind users to replace the rubber pads, making it difficult for users to know when the rubber pads need to be replaced, which is inconvenient to use. Utility Model Content

[0010] To address the shortcomings of existing technologies, this utility model provides a non-slip clamping fixture for processing thin-walled brackets, solving the problem that existing fixtures are inconvenient to use.

[0011] To achieve the above objectives, this utility model provides the following technical solution:

[0012] A thin-walled bracket processing fixture with anti-slip clamping includes a base plate, two fixed seats are fixedly connected to the top surface of the base plate, a guide groove is formed on the surface of the base plate, a damping turntable is fixedly connected to one end of the top surface of the base plate, a movable component for clamping items is slidably connected to the top surface of the base plate, and an anti-slip mechanism is provided on the side of the movable component close to one of the fixed seats for anti-slip purposes. A limit mechanism is fixedly connected to the side of the damping turntable away from the base plate. The movable component includes a movable block, a guide slider and a first lead screw, the anti-slip mechanism includes a metal plate, a plug rod, a warning piece and a rubber anti-slip layer, and the limit mechanism includes a mounting bracket, a second lead screw, a third lead screw and the anti-slip component.

[0013] Preferably, the guide slider is fixedly connected to the bottom surface of the movable block, the movable block is slidably connected to the guide groove, and the first lead screw is rotatably connected to the movable block.

[0014] Preferably, the first lead screw is threadedly connected to one of the fixed seats, and the movable block has four insertion holes on the side adjacent to the other fixed seat.

[0015] Preferably, there are four insertion rods, each of which is inserted into one of the four sockets. The four insertion rods are also fixedly connected to the four corners of the metal plate. A warning element is fixedly connected to the side of the metal plate away from the insertion rods. A rubber anti-slip layer is fixedly connected to the side of the metal plate away from the insertion rods. The rubber anti-slip layer and the metal plate surround the warning element. When the rubber anti-slip layer wears down to a certain thickness, the warning element will be exposed. The warning element can be set to a conspicuous color as needed. When the warning element is exposed, it indicates that the anti-slip mechanism needs to be replaced. Text can also be printed on the side of the warning element away from the metal plate to remind the user to replace it. There is a certain amount of damping between the insertion rods and the sockets.

[0016] Preferably, the bottom of the mounting bracket is fixedly connected to a connecting rod, which is fixedly connected to the side of the damping turntable away from the base plate. The surface of the mounting bracket is provided with a slot, and the two inner sidewalls of the slot are provided with limit grooves.

[0017] Preferably, a second lead screw is threaded onto the surface of the mounting bracket, and a connecting sleeve is rotatably connected to one end of the second lead screw located inside the slot. Limiting sliders are fixedly connected to both sides of the connecting sleeve, and the limiting sliders are slidably connected to the limiting groove.

[0018] Preferably, the third lead screw is threadedly connected to the connecting sleeve, and the end of the third lead screw facing the base plate is threadedly connected to the anti-slip component. The anti-slip component includes a warning layer, an anti-slip part, and a threaded joint. The anti-slip part and the third lead screw surround the warning layer. When the anti-slip part is worn to a certain thickness, the warning layer will be exposed. At this time, it can be removed and replaced with a new one.

[0019] Preferably, a lever is fixedly connected to the end of the first lead screw away from the movable block, a lever is fixedly connected to the end of the second lead screw away from the connecting sleeve, and a lever is fixedly connected to the end of the third lead screw away from the anti-slip component.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. After prolonged use, the rubber anti-slip layer of the anti-slip mechanism will wear down. To prevent excessive wear of the rubber pad from affecting the anti-slip performance of the clamping mechanism, it needs to be replaced frequently. When the rubber anti-slip layer wears down to a certain thickness, a warning element will be exposed. The warning element can be set to a conspicuous color as needed. When the warning element is exposed, it indicates that the anti-slip mechanism needs to be replaced. Text can also be printed on the side of the warning element away from the metal plate to remind the user to replace it. When the anti-slip component wears down to a certain extent, the warning layer will be exposed. At this time, the entire anti-slip component can be disassembled from the third lead screw and replaced with a new one. Compared with the existing protective mechanism, this application has a warning structure, and both the anti-slip mechanism and the anti-slip component can be disassembled, which solves the problem that the existing clamps are inconvenient to use.

[0022] II. In this application, the thin-walled bracket is first placed on the top of the base plate, between the fixed seat and the movable component. The first lead screw is rotated by the lever to push the movable block and drive the guide slider to move in the guide groove, so that the two anti-slip mechanisms move closer to each other and finally clamp the thin-walled bracket. If a limiting mechanism is required, the anti-slip component is rotated to the top of the base plate by the damping turntable. The second lead screw can be rotated on the surface of the mounting bracket by the lever and push the connecting sleeve to move in the empty groove, thereby driving the third lead screw and the anti-slip component to move to the top of the thin-walled bracket. The anti-slip component can be rotated and raised and lowered on the surface of the connecting sleeve by the lever connected to the third lead screw, so that the anti-slip component abuts against the thin-walled bracket and further fixes it. If the limiting mechanism is not required, the limiting mechanism can be rotated out of the top space of the base plate, so that it has a high degree of adjustability. Attached Figure Description

Detailed Implementation

[0030] This application provides a non-slip clamping thin-walled bracket processing fixture, which effectively solves the problem that existing fixtures are inconvenient to use.

[0031] Example

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the technical solution in this application embodiment effectively solves the technical problem that existing fixtures are inconvenient to use. The overall idea is as follows:

[0033] To address the problems existing in the prior art, this utility model provides a thin-walled bracket processing fixture with anti-slip clamping, including a base plate 1. Two fixed seats 102 are fixedly connected to the top surface of the base plate 1. A guide groove 101 is opened on the surface of the base plate 1. A damping turntable 103 is fixedly connected to one end of the top surface of the base plate 1. An active component 2 for clamping items is slidably connected to the top surface of the base plate 1. An anti-slip mechanism 4 is provided on the side of the active component 2 that is close to one of the fixed seats 102. A limiting mechanism 6 is fixedly connected to the side of the damping turntable 103 away from the base plate 1. The active component 2 includes an active block 201, a guide slider 202 and a first lead screw 203. The anti-slip mechanism 4 includes a metal plate 401, a plug rod 402, a warning piece 403 and a rubber anti-slip layer 404. The limiting mechanism 6 includes a mounting bracket 601, a second lead screw 605, a third lead screw 607 and an anti-slip component 608.

[0034] The guide slider 202 is fixedly connected to the bottom surface of the movable block 201, the movable block 201 is slidably connected to the guide groove 101, and the first lead screw 203 is rotatably connected to the movable block 201.

[0035] The first lead screw 203 is threadedly connected to one of the fixed seats 102, and the movable block 201 has four insertion holes 3 on the side of the other fixed seat 102 that are close to each other.

[0036] There are four insertion rods 402, which are respectively inserted into four sockets 3. The four insertion rods 402 are respectively fixedly connected to the four corners of the metal plate 401. The warning element 403 is fixedly connected to the side of the metal plate 401 away from the insertion rods 402. The rubber anti-slip layer 404 is fixedly connected to the side of the metal plate 401 away from the insertion rods 402. The rubber anti-slip layer 404 and the metal plate 401 surround the warning element 403. When the rubber anti-slip layer 404 wears down to a certain thickness, the warning element 403 will be exposed. The warning element 403 can be set to a conspicuous color as needed. When the warning element 403 is exposed, it indicates that the anti-slip mechanism 4 needs to be replaced. Text can also be printed on the side of the warning element 403 away from the metal plate 401 to remind the user to replace it. There is a certain amount of damping between the insertion rods 402 and the sockets 3.

[0037] A connecting rod 602 is fixedly connected to the bottom of the mounting bracket 601. The connecting rod 602 is fixedly connected to the side of the damping turntable 103 away from the base plate 1. A slot 603 is opened on the surface of the mounting bracket 601. Limiting grooves 604 are opened on both inner side walls of the slot 603.

[0038] The mounting bracket 601 is threadedly connected to a second lead screw 605. One end of the second lead screw 605 located inside the slot 603 is rotatably connected to a connecting sleeve 606. Limiting sliders are fixedly connected to both sides of the connecting sleeve 606, and the limiting sliders are slidably connected to the limiting groove 604.

[0039] The third lead screw 607 is threadedly connected to the connecting sleeve 606. The end of the third lead screw 607 facing the base plate 1 is threadedly connected to the anti-slip component 608. The anti-slip component 608 includes a warning layer 6081, an anti-slip element 6082, and a threaded joint. The anti-slip element 6082 and the third lead screw 607 surround the warning layer 6081. When the anti-slip element 6082 is worn to a certain thickness, the warning layer 6081 will be exposed. At this time, the anti-slip component 608 can be removed and replaced with a new one.

[0040] The end of the first lead screw 203 away from the movable block 201 is fixedly connected to a lever 5; the end of the second lead screw 605 away from the connecting sleeve 606 is fixedly connected to a lever 5; and the end of the third lead screw 607 away from the anti-slip component 608 is fixedly connected to a lever 5.

[0041] Working principle:

[0042] In the first step, the thin-walled bracket is placed on top of the base plate 1, between the fixed seat 102 and the movable component 2. The first lead screw 203 is rotated by the lever 5 to push the movable block 201 and drive the guide slider 202 to move in the guide groove 101, so that the two anti-slip mechanisms 4 move closer to each other and finally clamp the thin-walled bracket. If the limiting mechanism 6 is required, the anti-slip component 608 is rotated to the top of the base plate 1 by the damping turntable 103. The second lead screw 605 is rotated on the surface of the mounting bracket 601 by the lever 5 and pushes the connecting sleeve 606 to move inside the empty groove 603, thereby driving the third lead screw 607 and the anti-slip component 608 to move to the top of the thin-walled bracket. The anti-slip component 608 is rotated and raised and lowered on the surface of the connecting sleeve 606 by the lever 5 connected to the third lead screw 607, so that the anti-slip component 608 abuts against the thin-walled bracket and further fixes it. If the limiting mechanism 6 is not required, the limiting mechanism 6 can be rotated out of the top space of the base plate 1.

[0043] The second step is that after the anti-slip mechanism 4 has been used for a long time, the rubber anti-slip layer 404 will wear out. In order to avoid the rubber pad from wearing out too much and affecting the anti-slip performance of the clamping, it needs to be replaced frequently. When the rubber anti-slip layer 404 wears to a certain thickness, the warning piece 403 will be exposed. The warning piece 403 can be set to a conspicuous color as needed. When the warning piece 403 is exposed, it means that the anti-slip mechanism 4 needs to be replaced. It is also possible to print text on the side of the warning piece 403 away from the metal plate 401 to remind the user to replace it. When the anti-slip part 6082 wears to a certain extent, the warning layer 6081 will be exposed. At this time, the entire anti-slip component 608 can be removed from the third lead screw 607 and replaced with a new one.

[0044] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
