They are devices specifically designed to secure workpieces and ensure they occupy precise positions during construction or testing. Their importance lies in ensuring the stability and accuracy of workpieces during processing, thereby improving the precision and efficiency of mechanical manufacturing. Specifically, through their unique structure and functionality, fixtures firmly secure workpieces, preventing them from shifting or deforming, allowing them to withstand various construction operations and quality inspections. This securing function is crucial for ensuring the dimensional, shape, and positional accuracy of workpieces. With the continuous advancement and development of various manufacturing processes, the requirements for fixtures are becoming increasingly diverse and stringent. The specific constraints that fixtures must meet vary across different manufacturing processes. For example, fixtures may require specialized materials that are heat-resistant, corrosion-resistant, or high-strength; they may need to be compact to accommodate confined working environments; and they may need to be as lightweight as possible to reduce the burden on equipment. These constraints further demonstrate the complexity and importance of fixtures in the mechanical manufacturing process.

[0003] Existing clamps are heavy, inconvenient to operate in limited spaces, and difficult to provide a large clamping force.

[0004] To this end, we propose a pressure plate fixture that can be easily disassembled and assembled. Utility Model Content

[0012] It is further characterized by:

[0013] The pressure plate is provided with a clamping groove at one end of the limiting groove, and the first clamping jaw can be located in the clamping groove when the pressure plate is pressed, thereby preventing the first clamping jaw from moving.

DETAILED DESCRIPTION

[0034] The specific implementation of the present utility model will be described below with reference to the accompanying drawings.

[0035] like Figures 1-8 As shown, a pressure plate clamp that can be easily disassembled and assembled includes a sliding clamp 1, a rotating clamp 2 and a pressure plate 3.

[0036] The pressure plate 3 is hollow, and both sides of the pressure plate 3 are slender pressure surfaces. A cylindrical pin 303 is provided at one end of the pressure plate 3, and the axis of the cylindrical pin 303 coincides with the axis of the pressure plate 3. Two limiting grooves 301 are provided at the bottom of the other end of the pressure plate 3. The two limiting grooves 301 are arranged at intervals. The pressure plate 3 is provided with a clamping groove 304 at the top of one end of the two limiting grooves 301, and the pressure plate 3 is also provided with a positioning hole 302 at one end of the two limiting grooves 301.

[0037] The rotating clamp 2 includes a second base plate 201, and a placement groove 206 is provided on one side of the top of the second base plate 201. The cylindrical pin 303 of the pressure plate 3 can be placed in the placement groove 206, and when the sliding clamp 1 rotates, it can drive the cylindrical pin 303 of the press 3 to rotate in the placement groove 206.

[0038] A fixed shaft 207 is provided on the second base plate 201, on which a rotating member 202 is rotatably provided. The rotating member 202 can rotate along the second base plate 201. A second lever 203 is rotatably provided on the rotating member 202. A second clamping jaw 204 is provided at one end of the second lever 203, and an arc-shaped groove 205 is provided at the bottom of the second clamping jaw 204. A second spring 208 is provided at the bottom of the other end of the second lever 203, and the other end of the second spring 208 is connected to the rotating member 202. The second lever 203 has a recessed surface above the second spring 208, which can enhance the feel when pressing the second lever 203. The second lever 203 is provided with a pressing portion at one end of a submerged concave surface. By pressing the second lever 203, the second lever 203 moves downward, driving the second clamping jaw 204 to move upward. When the pressing portion of the second lever 203 is not pressed, the second lever 203 is squeezed upward under the elastic force of the second spring 208, causing the pressing portion of the second lever 203 to move upward, thereby driving the second clamping jaw 204 to move downward, until the pressing portion of the second lever 203 is at the highest point and the second clamping jaw 204 completes the clamping.

[0039] The sliding clamp 1 includes a fixed plate 101 and a first base plate 102, and the fixed plate 101 and the first base plate 102 are connected by a rotating shaft 111. The first base plate 102 can rotate along the rotating shaft 111. One end of the first base plate 102 is connected to the fixed plate 101 through an eccentric screw 112 and a screw 113. The first base plate 102 is provided with a U-shaped notch 103 at the screw 113, and the screw 113 is in the U-shaped notch 103. After loosening the screw 113, the first base plate 102 can be rotated along the rotating shaft 111 by rotating the eccentric screw 112. The U-shaped notch 103 of the first base plate 102 can move on the screw 113. After the first base plate 102 rotates, the first base plate 102 and the fixed plate 101 are fixed by tightening the screw 113.

[0040] A slide groove 106 is provided in the first base plate 102, and a sliding slide 107 is provided in the slide groove 106. A rotatable first lever arm 108 is provided on the top of the slide 107. A first spring 109 is provided at one end of the first lever arm 108, and one end of the first spring 109 is connected to the slide 107. The first spring 109 can provide an upward elastic force. In the absence of external force, the first spring 109 can push the first lever arm 108 upward.

[0041] The first force arm 108 is provided with a curved surface above the first spring 109, and the part of the first force arm 108 provided with the curved surface is a pressing part, and the other end of the first force arm 108 is provided with a first clamping jaw 110. The first clamping jaw 110 and the first base plate 102 are provided with two limiting columns 105 and a positioning pin 104 near one end of the first clamping jaw 110.

[0042] During specific use, press the pressing part of the first force arm 108, and then pull the first force arm 108 to the side away from the first clamping jaw 110, so that the first clamping jaw 110 is in an open state, press the pressing part of the second force arm 203, and then rotate the second force arm 203 to drive the second clamping jaw 204 to rotate, so that the second clamping jaw 204 is in an open state; place the pressure plate 3, and position the pressure plate 3 through the cooperation of the positioning pin 104 and the positioning hole 302, the cylindrical pin 303 is placed in the placement groove 206, and the two limiting columns 105 are respectively in the two limiting grooves 301. The pressing portion of the first lever 108 is pressed, pushing the first lever 108 toward the pressure plate 3 so that the first clamping jaw 110 is above the clamping groove 304. The first lever 108 is released. Under the elastic force of the first spring 109, the first lever 108 presses the first clamping jaw 110 downward. The first clamping jaw 110 is in the clamping groove 304. The sliding clamping jaw 1 completes the pressing of the pressure plate 3. At the same time, the second lever 203 is pressed. The second lever 203 is then rotated so that the second clamping jaw 204 is above the cylindrical pin 303. The second lever 203 is released. Under the elastic force of the second spring 208, the second lever 203 presses the second clamping jaw 204 downward. The arc groove 205 of the second clamping jaw 204 presses above the cylindrical pin 303, preventing the second clamping jaw 204 from moving. This is not only easy to operate and lightweight, but also can provide a large clamping force in a limited space.

[0043] When the slender pressing surface of the pressing plate 3 is tilted due to process or other conditions, loosen the screw 113 and turn the eccentric screw 112 to drive the first base plate 102 to rotate along the rotating shaft 111. The first base plate 102 and the first clamping jaw 110 drive the pressing plate 3 to rotate along the cylindrical pin 303 until the slender pressing surface of the pressing plate 3 is horizontal. Then tighten the screw 113 to fix the first base plate 102 and the fixed plate 101, and then fix the pressing plate 3, so that the slender pressing surface of the pressing plate 3 can be adjusted when it is uneven, so that the slender pressing surface of the pressing plate 3 remains horizontal after adjustment.
