DETAILED DESCRIPTION

[0018] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0019] Combined with Figure 1-2 It can be seen that the device for clamping and positioning in a pallet includes a clamp block assembly a, a rotating assembly b and a supporting mounting plate assembly c. Two clamp block assemblies a are relatively arranged on the supporting mounting plate assembly c, and the rotating assembly b is located between the two clamp block assemblies a. When in use, the rotating assembly b and the supporting mounting plate assembly c are respectively installed at the application site where clamping is required. The rotating assembly b drives the clamp block assembly a to move on the supporting mounting plate assembly c, thereby realizing the action of clamping or loosening, and realizing the clamping and loosening of the workpiece by the clamp block assembly a.

[0020] The following is a detailed introduction to each institution: The clamp block assembly a includes a clamp block 1 and a swing rod 2. The bottom of the swing rod 2 is fixed on the slide block 7. The two clamp blocks 1 are arranged opposite to each other, and the two clamp blocks 1 are used to clamp the workpiece. Figure 1 A swing rod support block 14 is provided at the bottom of the swing rod 2, and the swing rod support block 14 is fixedly connected to the slide groove slider 7 by multiple screws to achieve stable installation of the swing rod 2.

[0021] The swing rod 2 includes a vertical section fixedly connected to the slide block 7, and the end of the vertical section is connected to a horizontal reversing section, and the end of the horizontal reversing section is provided with a near section extending in opposite directions, and the clamping block 1 is provided at the end of the near section. In order to adapt to the shapes of various workpieces, the installation space requirements of the present invention, and to prevent the clamping force from being too large, the swing rod 2 is set into a multi-section structure. When the clamping force is too large, the clamping force of the clamping block 1 will eventually be released through the transfer of the multi-section structure, leaving an allowable amount of operation error for on-site operation, and reserving a certain amount of time for on-site operators to find problems, delay damage, and reduce damage. At the same time, the multi-section structure can be flexibly set according to the direction of the site. The multi-section includes three sections, which are respectively fixed to the slide block 7, and a horizontal reversing section is provided at the end of the vertical section. The clamping block 1 is extended toward the outside of the support mounting plate assembly c, and the end of the horizontal reversing section is provided with a near section extending inwardly with super strong strength. The clamping block 1 is installed at the end of the near section, and the space between the two clamping blocks 1 is the space for placing the workpiece. The clamping blocks 2 are usually symmetrically distributed on both sides of the workpiece.

[0022] The clamp block 1 is connected to the adjacent section on one side in the shape of a rectangular plate, and on the other side is a rubber gasket. The rubber gasket is horizontally concave in the middle and convex on the upper and lower sides. Figure 2 The concave middle part is easy to fit with the workpiece, and the two sides of the concave part fit with the workpiece surface to increase the fitting surface. The rubber gasket increases the contact friction and has a certain clamping buffer effect to prevent wear on the workpiece surface during clamping.

[0023] The rotating general assembly b includes a rotating disc 12, and a rotating support seat 11 is arranged below the rotating disc 12. The center of the rotating support seat 11 is connected to the center of the rotating disc 12 by a central driving rod 17 that penetrates the center. The lower end of the central driving rod 17 is connected to a reducer, and the reducer is connected to a motor. The motor drives the central driving rod 17 to rotate, driving the rotating disc 12 to rotate, and then driving the pull rod 6 to pull the clamping block assemblies a on both sides to move toward or away from each other synchronously.

[0027] The slide block 7 is in the shape of a rectangular plate, and a slide block movably engaged in the slide track 3 is provided at the bottom of the slide block 7 near the two ends.

[0028] In order to lock the present invention after clamping in place and keep it in a clamped state during operation or transportation, a spring latch 10 is provided on the outer side of one of the clamping block components a, and a spring latch fixing seat 9 is provided on the support mounting plate component c. The spring latch fixing seat 9 is provided with a plurality of positioning holes 18, and the spring latch 10 can be inserted into the positioning holes 18 on the spring latch fixing seat 9 for positioning.

[0029] The spring latch 10 is installed in the following manner: a spring latch positioning plate 8 is arranged near the bottom of the back of the swing rod 2 near the spring latch fixing seat 9.

A latch hole is provided on the side parallel to the spring latch fixing seat 9. The spring latch 10 is inserted into the latch hole and extends downward to be inserted into the positioning hole 18 on the spring latch fixing seat 9. When the clamping block 1 of the present invention needs to be loosened, the spring latch 10 is manually taken out and the motor is started, so that the clamping block 1 can be moved toward the outside to loosen the workpiece.

[0030] For the safety of the device of the present invention, that is, the last guarantee of the range of the moving stroke, the two ends of the chute track 3 under any clamping block assembly a are provided with positioning seats 5 facing each other, and the positioning seats 5 are fixed to the support mounting plate 16 through the positioning seat fixing plate 4. The positioning seat fixing plate 4 is a plate with a right angle, one side is fixed to the support mounting plate 16, and the other side is perpendicular to the support mounting plate 16. The positioning seat 5 is fixed to the surface of the support mounting plate 16 facing the chute track 3, which is perpendicular to the support mounting plate 16.

[0032] Step 2: Repeat step 1 to install several clamping and positioning devices in the pallet, distributed along the length direction of the workpiece to be clamped; Step 3: Open the clamping and positioning device in the pallet: Before placing the workpiece, the two clamping blocks 1 of the clamping and positioning device in all pallets are in the open state. At this time, the two slide block sliders 7 are the farthest apart.

[0033] Step 4: Placing the workpiece: Suspend the workpiece between the two clamping blocks 1 of the clamping and positioning device in each pallet through a lifting mechanism, or place the workpiece on a support frame so that the workpiece is located between the two clamping blocks 1 of the clamping and positioning device in each pallet.

[0034] Step 5: Clamp the workpiece: start the motor to drive the rotating disc 12 to rotate. The rotating disc 12 moves toward the middle with the end of the pull rod 6. The other end of the pull rod 6 pulls the respective slide blocks 7 to move toward each other. The clamping blocks 1 approach each other and finally fit onto the workpiece. Set the number of rotations for the motor or set the torque threshold so that the motor can stop working after the clamping block 1 clamps the workpiece.

The test is to start the motor to drive the rotating disc 12, so that the clamping block 1 clamps the workpiece, and the motor can stop the motor. When it is the number of rotations, according to the different specifications of the workpiece, the number of rotations of the motor in each group of two clamping blocks 1 at the farthest distance and in the process of clamping to the workpiece surface is obtained by the test method; when it is the torque threshold, a pressure sensor is set on the output shaft of the motor, and the clamping force range of the clamping block 1 clamping the workpiece is obtained by the test method, and the torque threshold is set within the clamping force range. According to the different parts of the workpiece, the device of the present invention at different parts of a workpiece may have different moving distances of the clamping block 1. It is also possible that the setting size of the device of the present invention is different in different parts of the workpiece according to the size of the workpiece.

[0037] Step 7: Release the workpiece: When the workpiece needs to be transferred, after supporting or suspending the workpiece, first pull out the spring latch 10 from the positioning hole 18 of the spring latch fixing seat 9, then start the motor, rotate the rotating disk 12, the pull rod 6 pushes the slide block 7 to move outward, and the clamp 1 is removed from the workpiece surface.
