[0013] The present utility model will be described in detail below in conjunction with the specific embodiments:

[0014] Such as Figure 1 and Figure 2A synchronous clamping tooling for wire cutting of multiple bar materials as shown, including a fixture body 1, a base 2, a support column 21, a first limiting rod 3, a second limiting plate 4, an insertion plate 41, a linear slide rail 5, a slider 51, a transmission seat 6, a spring 61, a telescopic guide rod, a support plate 7, a rotating shaft 8, an adjusting sleeve 82, an adjusting roller 83 and a tension spring 9. The fixture body 1 is fixedly installed on the base 2 through the support column 21. A plurality of bar material clamping channels are horizontally and linearly distributed on the fixture body 1. A jack communicating with the bar material clamping channels is vertically arranged on the left side of the fixture body 1. The first limiting rod 3 is slidably inserted and installed in the jack. Chambers 13 are symmetrically arranged at the upper and lower parts of the fixture body 1. Two linear slide rails 5 are parallel and fixedly installed at the bottom of the chambers 13. The slider 51 is fixedly installed at the bottom of the transmission seat 6. The slider 51 is slidably installed on the linear slide rail 5. Four telescopic guide rods are distributed in a rectangle, and their lower ends are fixedly installed on the transmission seat 6. The support plate 7 is fixedly installed at the top of the telescopic guide rods. The spring 61 is sleeved on the telescopic guide rods. The upper and lower ends of the spring 61 act on the support plate 7 and the transmission seat 6 respectively. First limiting teeth are arranged on the top surface of the support plate 7. Second limiting teeth matching with the first limiting teeth are arranged on the bottom surface of the insertion plate 41. The two ends of the tension spring 9 are respectively fixedly connected with the transmission seat 6 and the right side wall of the chamber 13. The upper and lower ends of the rotating shaft 8 are respectively rotatably installed on the top wall and the bottom wall of the chamber 13. The adjusting roller 83 is fixedly sleeved on the rotating shaft 8 at the edge position. The adjusting sleeve 82 is fixedly installed at the left end of the transmission seat 6. The adjusting roller 83 is located in the adjusting sleeve 82. Under the action of the tension of the tension spring 9, the adjusting sleeve 82 is always pressed against the adjusting roller 83. Two insertion plates 41 are respectively vertically and fixedly installed at the upper and lower ends of the second limiting plate 4. After the insertion plates 41 are inserted and installed in the chambers 13, the top surfaces of the insertion plates 41 are pressed against the top walls of the chambers 13. The second limiting teeth on the insertion plates 41 cooperate with the first limiting teeth on the support plate 7 for fixed limiting. A pressing bolt 12 communicating with each bar material clamping channel is also screwed and installed on the fixture body 1.

[0015] A limiting bolt 91 for restricting the upward movement limit position of the support plate 7 is screwed and installed on the top wall of the chamber 13, avoiding the problem that the support plate 7 rises too high under the action of the elastic force of the spring 61, resulting in blockage between the insertion plate 41 and the support plate 7 during the insertion and installation.

[0016] A ball bearing is fixedly installed on the top wall of the chamber 13. The cage of the ball bearing is fixedly installed on the top wall of the chamber 13. The rotating shaft 8 is fixedly installed in the rotating body of the ball bearing. This installation method has the advantages of firm installation and convenient rotation.

[0017] On the left side of the fixture body 1, there is an observation notch 11 communicating with the jack and each bar clamping channel. Through the observation notch 11 that penetrates from front to back, it can be observed whether the left end of the bar blank 10 abuts against the first limiting rod 3, so as to avoid the problem that the left end of the bar blank 10 cannot abut against the first limiting rod 3 for positioning due to sundries in the bar clamping channel.

[0018] In order to facilitate pulling out the first limiting rod 3 from the jack after wear for maintenance and replacement, a pull ring 31 is provided at the top of the first limiting rod 3.

[0019] The bar blank 10 is pre-installed in the bar clamping channel of the fixture body 1. Rotate the rotating shaft 8 to drive the adjusting roller 83 to rotate, so that the combination of the adjusting sleeve 82 and the transmission seat 6 moves to the right along the linear slide rail 5 under the action of the pulling force of the tension spring 9, and the second limiting plate 4 is inserted and installed in the chamber 13. After the insertion plate 41 is inserted and installed in the chamber 13, the top surface of the insertion plate 41 is pressed against the top wall of the chamber 13, and the second limiting teeth on the insertion plate 41 cooperate with the first limiting teeth on the support plate 7 for fixed positioning. When the second limiting teeth and the first limiting teeth cooperate for positioning and moving, the support plate 7 is squeezed to move upward against the elastic force of the spring 61 and then bounce upward and reset, preventing the second limiting plate 4 from moving to the right and coming out. Since the cooperation of the first limiting teeth and the second limiting teeth cannot completely press and fix the bar blank 10 by the second limiting plate 4 and the first limiting rod 3, at this time, rotate the rotating shaft 8 to drive the adjusting roller 83 to rotate, and the eccentrically arranged adjusting roller 83 pushes the combination of the adjusting sleeve 82 and the transmission seat 6 to move to the left along the linear slide rail 5 against the pulling force of the tension spring 9 until the bar blank 10 is completely pressed and fixed by the cooperation of the second limiting plate 4 and the first limiting rod 3. At this time, tighten the compression bolt 12 to press and fix the bar blank 10, that is, the clamping and fixing of the bar blank 10 is completed. Rotate the limit bolt 91 to move upward and push the support plate 7 to move upward until the second limiting teeth and the first limiting teeth are separated, and then the second limiting plate 4 can be pulled out of the chamber 13.
