Description
Technical Field
[0001] This utility model relates to the field of thin plate vise technology, specifically a fragile thin plate vise. Background Technology
[0002] In the fields of precision manufacturing, semiconductors, optical components and special glass processing, the application of thin plates with high brittleness (such as glass, ceramics, silicon wafers, sapphire, etc.) is becoming increasingly widespread. When drilling, milling, cutting or grinding such fragile thin plates, they are clamped and fixed by thin plate vises.
[0003] Traditional fixtures must be clamped together for stability, which obstructs the machining area. When the fixture is loosened for full-area machining, the workpiece is prone to displacement or vibration due to loss of fixation, resulting in decreased accuracy or even damage. Consequently, it is impossible to provide a non-interference operating space for machining tools without sacrificing overall stability, especially for efficient, full-process precision machining of the perimeter and top surface of thin plates. Utility Model Content
[0004] The purpose of this utility model is to develop a vise for fragile thin plates. It solves the problem that traditional clamps must be clamped as a whole for stability, which obstructs the processing area. When the clamp is loosened for full-area processing, the workpiece is prone to displacement or vibration due to loss of fixation, resulting in decreased accuracy or even damage. This makes it impossible to provide a non-interference operating space for the processing tools without sacrificing overall stability, especially for efficient and precise full-process processing of the four sides and the top surface of thin plates.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a fragile thin plate vise, including a fixed clamp fixedly installed on the upper surface of the base, a material feeding groove opened on the upper surface of the fixed clamp, a cylinder fixedly installed on one side of the fixed clamp, the output end of the cylinder extending through the fixed clamp to the other side of the fixed clamp, a movable clamp fixedly installed on the output end of the cylinder, a thin plate placed inside the material feeding groove, one side of the thin plate abutting against the movable clamp, and a first auxiliary clamping component and a second auxiliary clamping component respectively installed on the upper surface of the base, the auxiliary clamping ends of the first auxiliary clamping component and the second auxiliary clamping component are both located above the thin plate.
[0006] In some embodiments, the first auxiliary clamping assembly includes a first corner cylinder, which is fixedly mounted on the upper surface of the base, and a first pressure plate is fixedly mounted on the output end of the first corner cylinder, which is positioned above the thin plate.
[0007] In some embodiments, the second auxiliary clamping assembly includes a second corner cylinder, which is fixedly mounted on the upper surface of the base. A second pressure plate is fixedly mounted on the output end of the second corner cylinder. An adapter plate is provided inside one end of the second pressure plate, and a bolt is inserted into one end of the second pressure plate. The second pressure plate is rotatably connected to the adapter plate via the bolt. A locking nut is threaded onto the outer surface of one end of the bolt. The lower surface of the locking nut abuts against the upper surface of the second pressure plate. The adapter plate is positioned above the thin plate.
[0008] In some embodiments, sensor mounting slots are provided on both sides of the movable fixture, and displacement sensors are installed inside the sensor mounting slots.
[0009] In some embodiments, an air pipe is fixedly installed on one side of the base, the air pipe is connected to the interior of the movable clamp, and a dust discharge port is opened on one side of the base, the dust discharge port is connected to the interior of the movable clamp.
[0010] In some embodiments, a misalignment groove is formed on the upper surface of one end of the feeding trough.
[0011] Compared with the prior art, the present invention has the following beneficial effects: (1) When the area blocked by the first pressure plate needs to be processed, the control system commands the first corner cylinder to move, drive the first pressure plate upward and rotate ° to completely swing away from the top of the thin plate, and completely release the blocked area. At the same time, the second auxiliary clamping component remains in working state, and the second pressure plate and the adapter plate continue to be firmly pressed on another area of the thin plate. At this point, there are no clamps blocking the areas on the four edges and the upper surface of the thin plate. The processing tool can freely approach and perform precise processing. When the area originally pressed by the second auxiliary clamping component needs to be processed, the second corner cylinder can be commanded to drive its pressure plate to swing up, and at the same time, the first corner cylinder can be commanded to move the pressure plate upward. (1) Drive the first pressure plate to swing back and press the processed or to be stabilized area. Through the alternating pressing and releasing of the two auxiliary clamping components, the thin plate can be stably processed without dead angles in the whole area; (2) By setting the air pipe connection pipe and the dust discharge port, the air pipe connection pipe can be connected to an external air source to blow air into the cavity inside the movable fixture, thereby blowing the debris that falls off the movable fixture from the dust discharge port, so as to facilitate cleaning the dead angles of the cavity inside the movable fixture; (3) The misalignment groove of this utility model is a structural notch located at one end of the material feeding groove of the fixed fixture, providing space for the operator to insert fingers or tools, so that thin and brittle workpieces can be safely and stably operated when being put in and taken out, avoiding damage caused by forced prying.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0016] Please see Figures 1-4As shown, this utility model is a fragile thin plate vise, including a base 1 with a fixed clamp 2 fixedly installed on the upper surface. The upper surface of the fixed clamp 2 has a material feeding groove 201. A cylinder 3 is fixedly installed on one side of the fixed clamp 2. In this embodiment, the cylinder 3 includes, but is not limited to, an SDA-63-70 model cylinder. The output end of the cylinder 3 extends through the fixed clamp 2 to the other side of the fixed clamp 2. A movable clamp 4 is fixedly installed on the output end of the cylinder 3. A thin plate 5 is placed inside the material feeding groove 201. One side of the thin plate 5 abuts against the movable clamp 4. A first auxiliary clamping assembly 8 and a second auxiliary clamping assembly are respectively installed on the upper surface of the base 1. Part 9, the auxiliary clamping ends of the first auxiliary clamping assembly 8 and the second auxiliary clamping assembly 9 are both located above the thin plate 5. The thin plate 5 to be processed is placed in the feeding groove 201 of the fixed fixture 2. The cylinder 3 is activated, and the movable fixture 4 is retracted to move towards the thin plate 5, applying the main clamping force to the thin plate 5 from the side to complete the initial centering and fixing. At the same time, the first corner cylinder 801 of the first auxiliary clamping assembly 8 drives the first pressure plate 802, and the second corner cylinder 901 of the second auxiliary clamping assembly 9 drives the second pressure plate 902 and the adapter plate 903, which together swing to the top of the thin plate 5 and press down to fully assist in clamping the thin plate from above.
[0017] To achieve the clamping and anti-positioning of the thin plate 5 during operation, in some embodiments, the first auxiliary clamping assembly 8 includes a first corner cylinder 801, which is fixedly mounted on the upper surface of the base 1. A first pressure plate 802 is fixedly mounted on the output end of the first corner cylinder 801, and the first pressure plate 802 is positioned above the thin plate 5. The second auxiliary clamping assembly 9 includes a second corner cylinder 901, which is fixedly mounted on the upper surface of the base 1. The output end of the second angle cylinder 901 is fixedly installed with a second pressure plate 902. One end of the second pressure plate 902 is provided with an adapter plate 903. A bolt 904 is inserted into one end of the second pressure plate 902. The second pressure plate 902 is rotatably connected to the adapter plate 903 through the bolt 904. A locking nut 905 is threaded on the outer surface of one end of the bolt 904. The lower surface of the locking nut 905 abuts against the upper surface of the second pressure plate 902. The adapter plate 903 is located above the thin plate 5.
[0018] In this embodiment, when it is necessary to process the area blocked by the first pressure plate 802, the control system commands the first corner cylinder 801 to move, driving the first pressure plate 802 upward and rotating 90° to completely swing away from the thin plate 5, thus completely releasing the blocked area. At the same time, the second auxiliary clamping component 9 remains in working state, and the second pressure plate 902 and the adapter plate 903 continue to firmly press against another area of the thin plate 5. Thus, the areas around the edges and the upper surface of the thin plate 5 that have been released are not obstructed by any clamps, and the processing tool can freely approach and perform precise processing. When it is necessary to process the area that was originally pressed by the second auxiliary clamping component 9, the second corner cylinder 901 can be commanded to swing its pressure plate up, and at the same time, the first corner cylinder 801 can be commanded to drive the first pressure plate 802 to swing back and press against the processed or to be stabilized area. Through the alternating pressing and releasing of the two auxiliary clamping components, the entire area of the thin plate can be processed without dead angles.
[0019] In some embodiments, sensor mounting slots 401 are provided on both sides of the movable clamp 4, and displacement sensors 6 are installed inside the sensor mounting slots 401.
[0020] Understandably, with this setup, by using displacement sensor 6, when cylinder 3 pushes movable clamp 4 to clamp thin plate 5, the system can accurately calculate the clamping force applied to the side of thin plate by reading the displacement data of the sensor. This achieves closed-loop control, ensuring that the clamping force can firmly fix the thin plate without causing it to break due to excessive force. At the same time, it can also monitor the repeatability accuracy of the clamp.
[0021] In some embodiments, an air pipe connection pipe 10 is fixedly installed on one side of the base 1, and the air pipe connection pipe 10 is internally connected to the movable clamp 4. A dust discharge port 7 is opened on one side of the base 1, and the dust discharge port 7 is internally connected to the movable clamp 4.
[0022] Understandably, with this setup, the air pipe 10 can be connected to an external air source to blow air into the cavity inside the movable clamp 4, thereby blowing out the debris that falls off during processing inside the movable clamp 4 from the dust outlet 7, thus facilitating the cleaning of the dead corners inside the cavity of the movable clamp 4.
[0023] In some embodiments, a misalignment groove 202 is provided on the upper surface of one end of the feeding groove 201. The misalignment groove 202 is a structural notch located at one end of the feeding groove 201 of the fixed fixture 2, providing space for the operator to insert fingers or tools, so that thin and brittle workpieces can be safely and smoothly operated when being put in and taken out, avoiding damage caused by forced prying.
[0024] The working process of the vise in this embodiment is as follows: The thin plate 5 to be processed is placed in the feeding slot 201 of the fixed clamp 2. The cylinder 3 is activated, and the movable clamp 4 is retracted to move towards the thin plate 5, applying the main clamping force to the thin plate 5 from the side to complete the initial centering and fixing. At the same time, the first corner cylinder 801 of the first auxiliary clamping component 8 drives the first pressure plate 802, and the second corner cylinder 901 of the second auxiliary clamping component 9 drives the second pressure plate 902 and the adapter plate 903, which together swing to above the thin plate 5 and press down, providing comprehensive auxiliary clamping of the thin plate from above to prevent it from jumping or moving during subsequent processing. Upon shattering, the thin plate is completely fixed. When it is necessary to process the area obstructed by the first pressure plate 802, the control system commands the first corner cylinder 801 to actuate, driving the first pressure plate 802 upward and rotating it 90° to completely swing it away from the thin plate 5, fully releasing the obstructed area. At the same time, the second auxiliary clamping assembly 9 remains in working condition, and the second pressure plate 902 and the adapter plate 903 continue to firmly press against another area of the thin plate 5. At this point, the areas around the edges and the upper surface of the thin plate 5 that have been released are no longer obstructed by any clamps, and the processing tools can freely approach and perform precise processing. When it is necessary to process the area originally obstructed by the second... When the area pressed by the auxiliary clamping component 9 is reached, the second corner cylinder 901 can drive its pressure plate to swing up, while simultaneously instructing the first corner cylinder 801 to drive the first pressure plate 802 to swing back and press the processed or to be stabilized area. Through the alternating pressing and releasing of the two auxiliary clamping components, the entire area of the thin plate can be processed without dead angles. Through the setting of the air pipe connection pipe 10 and the dust exhaust port 7, the air pipe connection pipe 10 can be connected to an external air source to blow air into the cavity inside the movable fixture 4, thereby blowing out the debris that falls from the movable fixture 4 through the dust exhaust port 7, achieving the effect of facilitating the cleaning of the dead corners inside the cavity of the movable fixture 4. The misalignment groove 20 2 is a structural notch located at one end of the material feeding groove 201 of the fixed fixture 2, providing space for the operator to insert their fingers or tools, so that thin and brittle workpieces can be safely and smoothly operated when being put in and taken out, avoiding damage caused by forced prying. With the setting of displacement sensor 6, when the cylinder 3 pushes the movable fixture 4 to clamp the thin plate 5, the system can accurately calculate the clamping force applied to the side of the thin plate by reading the displacement data of the sensor. This realizes closed-loop control, ensuring that the clamping force can firmly fix the thin plate without causing the thin plate to break due to excessive force. At the same time, it can also monitor the repeatability accuracy of the fixture.
