Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, and more specifically to chuck clamps, specifically a jaw-back clamping chuck clamp for workpiece clamping. Background Technology

[0002] In the machinery manufacturing industry, a jaw-back clamping chuck fixture is needed to clamp and fix the workpiece. The jaw-back clamping chuck fixture is a type of fixture used to hold workpieces. Its feature is that it can adapt to workpieces of different shapes and sizes through a pull-back design. It can clamp workpieces of different shapes and sizes, which facilitates rapid processing of workpieces, thereby improving work efficiency and accuracy. The jaw-back clamping chuck fixture can be operated manually, pneumatically, or hydraulically, which can save the step of manual alignment.

[0003] Existing jaw clamping chuck fixtures require multiple structural clamping operations during use, resulting in low workpiece processing efficiency and increased operator and equipment costs. This hinders both improving processing efficiency and cost savings. Furthermore, the inability to quickly disassemble and assemble the clamping plate impedes replacement and maintenance efficiency and reduces market liquidity. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a jaw-back clamping chuck fixture for workpiece clamping. This solution addresses the problems of existing jaw-back clamping chuck fixtures requiring multiple structural clamping operations, resulting in low workpiece processing efficiency, increased operator and equipment costs, and hindering cost savings while improving processing efficiency. Furthermore, the inability to quickly disassemble and assemble the clamping plate impedes replacement and maintenance efficiency and market liquidity.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a jaw-back clamping chuck fixture for workpiece clamping, comprising two symmetrically arranged hinge fixing seats and a clamping assembly, wherein the clamping assembly is installed between the two hinge fixing seats and is used to clamp and fix the workpiece, the clamping assembly comprising a threaded adapter plate and a positioning pin, wherein the positioning pin passes through the threaded adapter plate and is externally fixedly sleeved with a pull plate, wherein two pull rods are symmetrically arranged on the pull plate on both sides of the positioning pin, and each pull rod is equipped with a pressure plate hinged to the hinge fixing seat, wherein a sliding groove is formed on the side wall of the pressure plate, wherein a first pin fixedly passes through the sliding groove and is fixedly passed through the side wall of the pull rod, and a second pin fixedly passes through the side wall of the pressure plate and is fixedly passed through the side wall of the hinge fixing seat.

[0006] By adopting the above technical solution, the threaded adapter is connected to the machine tool. When it is necessary to clamp the workpiece, the workpiece is placed between the two pressure plates and close to the positioning pin. By moving the threaded adapter downward, the threaded adapter descends, causing the positioning pin to lose support. The descent of the positioning pin drives the pull plate to descend, and also drives the workpiece to descend. The descent of the pull plate drives the pull rod to descend, and the descent of the pull rod drives pin one to descend. Pin one descends and pulls the pressure plate downward through the slide groove. Since pin two passes through the side wall of the hinge fixing seat and then through the side wall of the pressure plate, pin two can limit the lower end of the pressure plate. The pressure plate can only rotate along the central axis of pin two. Therefore, when the pressure plate is subjected to downward pulling force, it can rotate downward. While the end of the pressure plate away from pin two rotates downward, it moves towards the workpiece. The pressure plates on both sides can squeeze the sides of the workpiece, thus clamping and fixing the workpiece.

[0007] The present invention is further configured such that a positioning diamond pin is fixedly inserted above the positioning pin.

[0008] The present invention is further configured such that: a panel sleeved on the outside of the positioning pin and each of the pull rods is fixedly installed below the hinge fixing seat.

[0009] The present invention is further configured such that: two positioning seats are symmetrically installed on the panel, respectively located above the two sides of the positioning pin; each positioning seat has a pre-positioning pin fixedly installed on the side facing each other, and a cover plate is fixedly installed on the side of each positioning seat facing away from each other.

[0010] The present invention is further configured such that: a positioning body is fixedly installed below the panel and sleeved on the outside of the threaded adapter and the pull plate, and the positioning body is sleeved below the positioning pin and the pull rod.

[0011] The present invention is further configured such that: each of the first pins and each of the second pins is equipped with a spring, and a locking rod is fixedly installed on the spring, which passes through the side wall of each of the first pins and each of the second pins.

[0012] In summary, this utility model has the following beneficial effects: it can accelerate the clamping and processing of different workpieces, significantly improve the efficiency of workpiece processing, reduce costs caused by a large number of operators and complex equipment structure, facilitate quick disassembly and assembly of the pressure plate, improve the efficiency of replacement and maintenance, and enhance market liquidity.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0021] like Figure 1-5As shown, the device includes two symmetrically arranged hinge fixing seats 1 and a clamping assembly 2. The clamping assembly 2 is installed between the two hinge fixing seats 1 and is used to clamp and fix the workpiece. The clamping assembly 2 includes a threaded adapter plate 201 and a positioning pin 202. The threaded adapter plate 201 can rotate and rise, and the positioning pin 202 can support the finished workpiece. The positioning pin 202 passes through the threaded adapter plate 201 and is externally fixedly fitted with a pull plate 203. The pull plate 203 can drive the positioning pin 202 and the pull rod 204 to rise and fall. Two pull rods 204 are symmetrically installed on the pull plate 203, located on both sides of the positioning pin 202. 4. The pressure plate 205 can be pulled by the pin 206 and the slide 3. Each pull rod 204 is equipped with a pressure plate 205 that is hinged to the hinge fixing seat 1. The pressure plate 205 can clamp the workpiece. The side wall of the pressure plate 205 is provided with a slide 3. The slide 3 can easily pass through the pin 206. The pin 206 is fixedly inserted in the slide 3 and is fixedly inserted in the side wall of the pull rod 204. The pin 206 can drive the pull rod 204 and the pressure plate 205 to connect through the slide 3. The side wall of the pressure plate 205 is provided with a pin 207 that is fixedly inserted in the side wall of the hinge fixing seat 1. The pin 207 can drive the pull rod 204 to connect with the hinge fixing seat 1.

[0022] according to Figure 2 As shown, the threaded adapter 201 is connected to the machine tool. When a workpiece needs to be clamped, the workpiece is placed between the two pressure plates 205 and pressed against the positioning pin 202. By moving the threaded adapter 201 downward, the threaded adapter 201 descends, causing the positioning pin 202 to lose its support. The descent of the positioning pin 202 drives the pull plate 203 to descend, which in turn drives the workpiece to descend. The descent of the pull plate 203 pulls the pull rod 204 to descend, which in turn drives the pin 206 to descend. The descent of the pin 206 allows the workpiece to descend. When the pressure plate 205 is pulled down through the slide groove 3, since the second pin 207 passes through the side wall of the hinge fixing seat 1 and then through the side wall of the pressure plate 205, the second pin 207 can limit the lower end of the pressure plate 205. The pressure plate 205 can only rotate along the central axis of the second pin 207. Therefore, the pressure plate 205 can rotate downward after being pulled downward. While the end of the pressure plate 205 away from the second pin 207 rotates downward, it moves towards the workpiece. The pressure plates 205 on both sides can squeeze the two sides of the workpiece and clamp and fix the workpiece.

[0023] like Figure 3 As shown, a positioning diamond pin 4 is fixedly inserted above the positioning pin 202. The positioning diamond pin 4 can mount the workpiece on the positioning pin 202, which helps to improve the stability of the workpiece.

[0024] like Figure 1 and Figure 3-4As shown, a panel 5 is fixedly installed below the hinge fixing base 1, which is sleeved on the outside of the positioning pin 202 and each tie rod 204. The panel 5 can support the hinge fixing base 1.

[0025] like Figure 1 and Figure 3 As shown, two positioning seats 6 are symmetrically installed on the panel 5, located above the positioning pins 202 on both sides. The positioning seats 6 can support the pre-positioning pins 7 and can be locked on both sides of the workpiece, thus better limiting the workpiece. The pre-positioning pins 7 are fixedly installed on the facing side of each positioning seat 6. The pre-positioning pins 7 can squeeze and position the two sides of the workpiece. The cover plates 8 are fixedly installed on the opposite side of each positioning seat 6, which facilitates the installation of the positioning seats 6.

[0026] like Figure 1 and Figure 3-4 As shown, a positioning body 9 is fixedly installed below the panel 5, which is sleeved on the outside of the threaded adapter plate 201 and the pull plate 203. The positioning body 9 can support the panel 5 and is sleeved below the positioning pin 202 and the pull rod 204.

[0027] like Figure 5 As shown, each pin 1 206 and each pin 2 207 is equipped with a spring 10. The spring 10 can drive the locking rod 11 to return to its original position. The locking rod 11 is fixedly installed on the spring 10 and passes through the side wall of each pin 1 206 and each pin 2 207. The locking rod 11 can limit the position of pin 1 206 and pin 2 207.

[0028] After pin 206 and pin 207 are respectively inserted into one side of the pull rod 204 and the hinge fixing seat 1, they are then inserted into the pressure plate 205, and then exit from the other side of the pull rod 204 and the hinge fixing seat 1, according to... Figure 2As shown, the diameters of pins 206 and 207, which pass through the pull rod 204 and hinge fixing seat 1, are exactly in contact with the pull rod 204 and hinge fixing seat 1. The diameter of the left end of pins 206 and 207 is larger than the diameter inside the pull rod 204 and hinge fixing seat 1, thus preventing pins 206 and 207 from moving to the right. The spring 10 can push the locking rod 11 to move away from pins 206 or 207, and the locking rod 11 can extend out of pins 206 and 207. On the outside of the side wall, the locking rod 11 can be located at the right end of the pull rod 204 and the hinge fixing seat 1, which can prevent the first pin 206 and the second pin 207 from moving to the left, limit the first pin 206 on the pull rod 204 and the slide groove 3, and limit the second pin 207 on the hinge fixing seat 1 and the pressure plate 205. When it is necessary to remove the pressure plate 205, by pressing the locking rod 11 and pulling the first pin 206 and the second pin 207 by hand, the first pin 206 and the second pin 207 can be pulled out, which can facilitate the removal of the pressure plate 205.
