However, in the machining process, the workpieces may generate high temperature, and the clamp is directly connected with the driving part, so that the high temperature of the workpiece is directly conducted to the driving part, thereby damaging the sealing rubber part of the driving part and causing the driving part to leak, which affects the driving capacity and service life. CONTENT OF THE UTILITY MODEL

[0003] The utility model aims at solving the above-mentioned problems and provides a high-temperature-resistant hand-held clamp.

[0004] The technical scheme of the application is implemented as follows:

[0005] The application provides a high-temperature-resistant hand-held clamp, which comprises a bearing base, the bearing base is provided with a slotted groove, a push rod part is installed in the slotted groove, a clamping device is installed at the piston end of the push rod part, and shaft rods are arranged at the two sides of the bearing base.

[0006] The clamping device comprises a support seat and a sleeve, the support seat is connected with the piston end of the push rod part, the sleeve is sleeved on the shaft rod, cavities are arranged at the two sides of the support seat, support rods are installed in the cavities, a receiving part rotatingly arranged on the support rod is arranged on the outer periphery of the sleeve, a connecting part is further arranged on the outer periphery of the sleeve, an installation plate is connected with the connecting part, a clamp seat is arranged on one side of the installation plate, and a clamping area for clamping materials is formed between the two clamp seats.

[0007] A guide rail part is further arranged on the bearing base, and a sliding seat is further arranged at the bottom of the installation plate and movably arranged on the guide rail part.

[0008] Through cooperation of the push rod part, when the support seat moves relatively, the two clamp seats move close to or away from each other, so that the clamping area is expanded or reduced.

[0009] In an embodiment, the installation plate is provided with an annular notch, and an annular protrusion is arranged on the side of the connecting part away from the sleeve.

[0010] The annular protrusion is sleeved in the annular notch.

[0011] When the installation plate moves along the guide rail part under cooperation of the sliding seat, the contact end points of the annular notch and the annular protrusion change.

[0012] In an embodiment, the clamp seat has a receiving opening, and two groups of symmetrical inclined slots are arranged on both sides of the clamp seat and communicate with the receiving opening.

[0013] The two groups of inclined slots form a limiting area for clamping the material.

[0014] In an embodiment, recesses are arranged on both sides of the guide rail, and protrusions are arranged on the slide corresponding to the positions of the recesses.

[0015] When the slide is installed on the guide rail, the protrusions are embedded in the recesses.

[0016] In an embodiment, a clamping groove is arranged on one side of the clamp seat close to the mounting plate, and a clamping block is arranged on the mounting plate corresponding to the position of the clamping groove.

[0017] When the clamp seat is attached to the mounting plate, the clamping block is embedded in the clamping groove, so that the clamp seat is movably installed on the mounting plate.

[0018] In an embodiment, the mounting flange is arranged on one side of the bearing base away from the clamping device.

[0019] In an embodiment, side plates are arranged on both sides of the bearing base, and mounting holes are arranged on the side plates.

[0020] The clamping device is located between the two groups of side plates.

[0021] The advantages or beneficial effects of the above technical solutions at least include:

[0022] The high-temperature-resistant hand-held clamp disclosed in the application can drive the support seat of the clamping device to move through the extension of the piston end of the push rod component. Since the two sides of the support seat are connected to the sleeve rotatably arranged on the shaft through the receiving part, and the sleeve is further provided with a connecting part connected to the mounting plate, when the support seat moves under the cooperation of the push rod component, the mounting plate can be driven to displace through the cooperation of the receiving part and the connecting part. Since the mounting plate has a clamp seat in contact with the material, when the material is located between the two groups of clamp seats, the push rod component can clamp the material. Through the arrangement of the clamping device, the material has a certain distance from the push rod component, thereby avoiding the problem that the heat of the material is directly transmitted to the push rod component to affect the sealing performance, and improving the service life of the push rod component.

[0038] Reference Figures 1-5 A high-temperature resistant hand gripper includes a support base 1 with a slot 11. A push rod component 2 is installed in the slot 11. The push rod component 2 is a cylinder in the prior art. A clamping device 3 is installed on the piston end of the push rod component 2. The clamping device 3 is adjusted by the extension and retraction of the piston end of the push rod component 2. Shafts 12 are provided on both sides of the support base 1, and the shafts 12 play a supporting role.

[0039] The clamping device 3 includes a support base 31 and a sleeve 32. The support base 31 is connected to the piston end of the push rod component 2. The sleeve 32 is sleeved on the shaft 12 and has a rotational degree of freedom about the shaft 12. Both sides of the support base 31 are provided with cavities and support rods are installed. The outer periphery of the sleeve 32 is provided with a receiving part 321 that is rotatably mounted on the support rod. By rotating the receiving part 321, the angle of the receiving part 321 can be adjusted when the support base 31 moves with the cooperation of the push rod component 2, thereby avoiding the situation of being limited. The outer periphery of the sleeve 32 is also provided with a connecting part 322, which is connected to a mounting plate 33. A clamping seat 34 is provided on one side of the mounting plate 33. A clamping area for clamping materials is formed between the two sets of clamping seats 34.

[0040] The support base 1 is also provided with a guide rail 4, and the bottom of the mounting plate 33 is also provided with a slide 332. The slide 332 is movably mounted on the guide rail 4. The guide rail 4 can limit the movement of the slide 332 and constrain the range of movement of the slide 332, thereby preventing the slide 332 from deviating during movement.

[0041] With the cooperation of the push rod component 2, when the support base 31 moves relative to each other, the two sets of clamping bases 34 move closer or further apart, thereby expanding or shrinking the clamping area. By changing the distance between the two sets of clamping bases 34, the clamping device 3 can be adapted to materials of different sizes.

[0042] Based on the above structure, by placing the material to be processed between the clamp seats 34 of the two sets of clamping devices 3, the piston end of the push rod component 2 drives the support seat 31 to move by driving the push rod component 2. During the movement, the sleeve 32 is rotated by the receiving part 321, thereby causing the connecting part 322 to drive the mounting plate 33 to move. Since the clamp seat 34 is provided on the mounting plate 33, the clamping operation of the material is completed when the inner wall of the clamp seat 34 abuts against the outer periphery of the material. Furthermore, the bottom of the mounting plate 33 is provided with a slide 332 mounted on the guide rail component 4. Therefore, by extending and retracting the push rod component 2 and by cooperating with the connecting part 322 and the receiving part 321, the mounting plate 33 can move along the length direction of the guide rail component 4. By setting the clamping device 3, the material can be clamped away from the push rod component 2, and heat cannot be quickly conducted to the push rod component 2, thereby protecting the push rod component 2 and improving its service life.

[0043] In one embodiment, reference is made to Figures 1-3 The mounting plate 33 has an annular groove 331, and the connecting part 322 has an annular protrusion 3221 on the side away from the sleeve 32, and the annular protrusion 3221 is fitted into the annular groove 331.

[0044] When the mounting plate 33 moves along the guide rail 4 with the cooperation of the slide 332, the contact endpoints of the annular groove 331 and the annular protrusion 3221 change. The annular snap-fit ​​method allows the mounting plate 33 to remain parallel by adjusting the connecting part 322 when the mounting plate 33 moves with the cooperation of the guide rail 4. The guide rail 4 can limit the movement of the slide 332.

[0045] In one embodiment, reference is made to Figures 1-3 The clamp base 34 has a receiving opening 341 for placing rectangular materials. Both sides of the clamp base 34 are provided with two sets of symmetrically distributed inclined slots 342, which are connected to the receiving opening 341. The two sets of inclined slots 342 can form a triangular cross section, so that when clamping materials, the force can be evenly distributed at each corner, thereby ensuring the stability of the clamping. It can also form three-point contact at the top and bottom ends of the cylindrical material, so that the pressure will not be concentrated at one point, but evenly distributed on three points, reducing the risk of damage to the material surface.

[0046] A limiting area for clamping the material is formed between the two sets of inclined slots 342, and the outer periphery of the material abuts against the two sets of inclined slots 342.

[0047] In one embodiment, reference is made to Figure 1 and Figure 4 The guide rail 4 has recesses 41 on both sides, and the slide 332 has protrusions 3321 corresponding to the recesses 41. The recesses 41 and protrusions 3321, and their cooperation, can provide precise guidance and positioning, ensuring that the slide 332 moves correctly and stably on the guide rail, reducing offset and vibration.

[0048] When the slide block 332 is installed on the guide rail 4, the protrusion 3321 is embedded in the recess 41. The protrusion 3321 embedded in the recess 41 can increase the contact area between the slide block 332 and the guide rail 4, thereby improving the rigidity of the overall structure, reducing deformation, and preventing the slide block 332 from falling off the guide rail 4 when subjected to lateral force, thus increasing the safety of the system.

[0049] In one embodiment, reference is made to Figure 1 and Figure 5 The clamp base 34 is provided with a slot 343 on the side near the mounting plate 33. The mounting plate 33 is provided with a block 333 at the position corresponding to the slot 343. The size of the block 333 and the slot 343 are matched so that when the block 333 is inserted into the slot 343, the outer periphery of the block 333 abuts against the inner wall of the slot 343.

[0050] When the clamp base 34 is in contact with the mounting plate 33, the locking block 333 is embedded in the locking groove 343, so that the clamp base 34 is movably mounted on the mounting plate 33. The movable mounting method can fix the clamp base 34 on the mounting plate 33, and through the cooperation of the locking block 333 and the locking groove 343, the size of the clamp base 34 can be adjusted according to the actual situation, so as to be suitable for materials of different sizes and improve the flexibility of clamping.

[0051] In one embodiment, reference is made to Figure 1 A mounting flange 13 is provided on the side of the bearing base 1 away from the clamping device 3. The mounting flange 13 enables the bearing base 1 to be mounted on the robotic arm, and the mounting flange 13 and the clamping device 3 are arranged in a parallel structure.

[0052] In one embodiment, reference is made to Figure 1 and Figure 2The support base 1 has side plates 14 on both sides, and mounting holes 141 on the side plates 14. The clamping device 3 is located between the two sets of side plates 14. The side plates 14 enable the support base 1 to be further installed, allowing the support base 1 to be installed in different positions according to the actual situation, and the installation is fixed and limited by the mounting holes 141.
