Description

Technical Field

[0001] The utility model relates to the field of clamping of processed parts, in particular to a clamping device for processing parts. Background Art

[0002] Common machined parts include shaft parts, gears, tools, connectors, etc. The workpiece clamping device is a device used to fix the machined parts during the processing to ensure the stability and accuracy of the machined parts during the production process.

[0003] The prior art has the following deficiencies: in the production process of tool processing parts, a quenching process is included. Quenching is a heat treatment technology in which the blade of the tool processing part is heated to an appropriate temperature and then quickly immersed in a cooling medium (such as water or oil) to quickly cool it down to obtain high hardness and high strength; since the temperature of the tool processing part in the quenching process is extremely high, generally speaking, ordinary metal clamps and rubber clamps are not suitable for directly bearing the high temperature in the heat treatment process. Under high temperature conditions, metal clamps may deform, become brittle or lose their original mechanical properties, while rubber clamps may soften, deform or even burn due to high temperature; therefore, the traditional quenching process has the problem of not having a suitable clamping fixture, resulting in the quenching process being able to process only one tool processing part at a time, making it difficult to carry out large-scale processing, which greatly affects the quenching efficiency of the tool processing part.

[0004] Therefore, it is necessary to invent a workpiece clamping device. Utility Model Content

[0005] To this end, the utility model provides a workpiece clamping device, which fixes the blade by a rotating bracket made of heat-resistant ceramic material, and then rotates the rotating bracket to allow the blade to easily escape from the slot of the rotating bracket, so as to solve the problem that ordinary metal clamps and rubber clamps are not suitable for directly bearing the high temperature in the heat treatment process, and the problem that the traditional quenching process has a lack of suitable clamping fixtures, resulting in the quenching process only being able to process one tool workpiece at a time, making it difficult to carry out large-scale processing, which greatly affects the tool quenching efficiency of the tool workpiece.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a workpiece clamping device, comprising a base and a blade, a rectangular opening is arranged in the center of the top surface of the base, and rotating brackets are rotatably installed on both sides of the inner wall of the rectangular opening on the top surface of the base, and a slot is arranged on the top surface of the rotating bracket, and the plurality of slots are evenly arranged on the top surface of the rotating bracket. The blade can be inserted into the slots on the top surface of the rotating bracket on both sides of the inner wall of the rectangular opening on the top surface of the base, and rotating the rotating bracket can make the blade fall out of the top surface slot.

[0007] Preferably, the rotating bracket is made of heat-resistant ceramic material, the rotating bracket can withstand the high temperature environment in the heat treatment process, and the blade can be tightly inserted into the slot.

[0008] Preferably, ears are fixedly installed on both ends of the rectangular opening on the top surface of the base, protrusions are provided on both sides of the rotating bracket close to the ears, the protrusions of the rotating bracket are inserted into the ears, and the rotating bracket is rotatably connected to the base through the ears.

[0009] Preferably, sliding rods are fixedly installed at the four corners of the top surface of the base, a sliding frame is arranged above the base, the sliding frame is a rectangular frame structure, circular holes are arranged at the four corners of the bottom surface of the sliding frame, the sliding rods pass through the circular holes arranged at the four corners of the bottom surface of the sliding frame, and the sliding frame is slidably installed on the sliding rods at the four corners of the top surface of the base.

[0010] Preferably, the upper end of the slide rod extends upward to above the slide frame, and a limiting end is fixedly mounted on the upper end of the slide rod, and the limiting end can limit the slide frame from sliding out of the slide rod.

[0011] Preferably, the two shorter sides of the inner wall of the sliding frame are provided with a first inclined surface, the rotating bracket is in an L-shaped structure, and the upper ends of the two rotating brackets on the sides away from each other are provided with a second inclined surface.

[0012] Preferably, when the base is placed frontally, the slide frame slides along the slide rod to the top surface of the rotating bracket due to gravity, and when the slide frame is close to the rotating bracket, the first inclined surface is in close contact with the second inclined surface.

[0013] Preferably, when the base is inverted, the slide frame slides along the slide rod away from the rotating bracket due to gravity, the first inclined surface is separated from the second inclined surface when the rotating bracket moves away from the rotating bracket, and the rotating brackets on both sides rotate to both sides due to gravity.

[0014] The beneficial effects of the utility model are as follows: the blade is fixed by a rotating bracket made of heat-resistant ceramic material, and the blade can be easily removed from the slot of the rotating bracket by rotating the rotating bracket, so that the fixture can withstand the high temperature in the heat treatment process, and multiple blades can be removed at the same time so that they can be put into water for quenching at the same time, which facilitates large-scale processing and improves the blade quenching efficiency of tool processing parts.

[0024] In the above embodiment, it should be noted that the blade 21 is fixed by a rotating bracket 17 made of heat-resistant ceramic material, and the blade 21 can be easily removed from the slot 19 of the rotating bracket 17 by rotating the rotating bracket 17, so that the fixture can withstand the high temperature in the heat treatment process, and multiple blades can be removed at the same time so that they can be quenched in water at the same time, which facilitates large-scale processing and improves the blade quenching efficiency of tool processing parts.

[0025] Example 2

The rotating bracket 17 can withstand the high temperature environment in the heat treatment process, and the blade 21 can be tightly inserted into the slot 19.

[0027] In the above embodiment, it should be noted that the rotating bracket 17 made of heat-resistant ceramic material enables the clamp to withstand the high temperature in the heat treatment process, thereby preventing the slot 19 from failing to clamp the blade 21 due to temperature changes.

[0028] Example 3

[0029] like Figure 1-Figure 5 As shown, a workpiece clamping device includes all the contents of Example 1. In addition, the two ends of the rectangular opening on the top surface of the base 11 are fixedly installed with hanging ears 12, the rotating bracket 17 is provided with protrusions on both sides close to the hanging ears 12, the protrusions of the rotating bracket 17 are inserted into the hanging ears 12, and the rotating bracket 17 is rotatably connected to the base 11 through the hanging ears 12, and the sliding rods 13 are fixedly installed at the four corners of the top surface of the base 11, and a sliding frame 15 is provided above the base 11. The sliding frame 15 is a rectangular frame structure, and the four corners of the bottom surface of the sliding frame 15 are provided with circular holes. The sliding rod 13 passes through the circular holes at the four corners of the bottom surface of the sliding frame 15, and the sliding frame 15 is slidably installed on the sliding rod 13 at the four corners of the top surface of the base 11, and the upper end of the sliding rod 13 extends upward to the top of the sliding frame 15, and the upper end of the sliding rod 13 is fixedly installed with a limiting end 14, and the limiting end 14 can limit the sliding frame 15 from sliding out of the sliding rod 13.

[0030] In the above embodiment, it should be noted that the ear 12 is a metal ear, the slide rod 13 is a metal slide rod, and the slide frame 15 is made of heat-resistant metal. Affected by the thickness of the base 11, the rotating bracket 17 can only rotate toward the slide frame 15. In the initial state, the rotating brackets 17 on both sides are parallel to each other. When the rotating brackets 17 on both sides rotate, the rotating brackets 17 on both sides form a certain angle, and the blade 21 can easily fall out of the slot 19.

[0031] Example 4

[0032] like Figure 1-Figure 5 As shown, a workpiece clamping device includes all the contents of Example 3, in addition, the first inclined surface 16 is provided on the shorter two sides of the inner wall of the slide frame 15, the rotating bracket 17 is L-shaped, and the upper ends of the rotating brackets 17 on both sides are away from each other.

When the base 11 is inverted, the sliding frame 15 slides away from the rotating bracket 17, and the rotating bracket 17 rotates to achieve the effect of causing the blade 21 to disengage from the slot 19.

[0034] The use process of the utility model is as follows: a technician in this field first lifts the slide frame 15 to insert the blade 21 into the slot 19, then puts down the slide frame 15, the slide frame 15 slides along the slide rod 13 under the influence of gravity and makes the first inclined surface 16 close to the second inclined surface 18, sends the utility model and the blade 21 into the combustion furnace for heating, and takes out the utility model after the blade 21 is heated to a certain temperature, and inverts the base 11 above the water surface. The slide frame 15 slides along the slide rod 13 under the influence of gravity and away from the rotating bracket 17, and the rotating bracket 17 rotates to both sides under the influence of gravity, so that the blade 21 escapes from the slot 19 and falls into the water for quenching process.
