Description

Technical Field

[0001] This invention relates to the field of clamp unlocking technology, specifically a clamp trajectory unlocking device. Background Technology

[0002] A fixture is a device used in mechanical manufacturing to fix a workpiece in the correct position for construction or inspection. It is also called a clamp. In a broader sense, any device used to quickly, conveniently and safely install a workpiece in any step of the process can be called a fixture.

[0003] Existing automated clamp unlocking mechanisms mostly use direct pressure unlocking. Direct pressure unlocking causes relative sliding between the unlocking mechanism and the clamp jaws. Installing rollers on the jaws at the unlocking pressure position can prevent sliding, but for some special jaws, such as rubber-coated jaws, rollers cannot be installed on the jaws. Direct pressure causing relative sliding will greatly shorten the rubber coating life. Even using rollers to press and unlock rubber-coated jaws will shorten the rubber coating life because the rollers crush the rubber. Summary of the Invention

[0004] The purpose of this invention is to provide a clamp trajectory unlocking device to solve the problems mentioned in the background art. During the unlocking process, only the clamp is pressed, and there is no relative sliding or rolling with the clamp, which can effectively protect the clamp. The clamp is made of soft material such as rubber coating. When the clamp enters or exits the clamp positioning groove, the unlocking mechanism swings to avoid it. Compared with translational avoidance, this structure is easier to achieve compact size, structural stability, high precision, and improved rubber coating life.

The inner wall of the connecting groove is slidably connected to a plurality of rotating rods. The rectangular grooves are all adapted to the positions of the rotating rods. The outer wall of each rotating rod is fixedly connected to an unlocking roller. The outer wall of the unlocking roller has a plurality of abutment grooves. The abutment grooves are all arranged in a circular array and are adapted to the size of the gripper.

[0008] Preferably, the clamping assembly includes a clamping frame and a clamping product. The inner walls on both sides of the clamping frame are provided with a plurality of mounting holes. The inner walls of the mounting holes are each equipped with a gripper. The grippers and the unlocking rollers are arranged in a linear array. The grippers are all adapted to the positions of the unlocking rollers. The clamping product is all adapted to the size of the grippers.

[0009] Preferably, a plurality of limiting holes are provided on one outer wall of the mounting plate, and the inner walls of the limiting holes are all connected to limiting bolts by threads. The limiting bolts are all slidably connected to the outer walls of the top and bottom ends of the rotating rod.

[0013] This invention provides an improved clamp trajectory unlocking device, which has the following improvements and advantages compared with the prior art:

[0014] Firstly, this invention, by setting up a mounting frame, a clamp positioning groove, an unlocking component, and a clamping component, uses a cam roller fixed on the unlocking plate to cooperate with the track groove of the track plate, so that the movement trajectory of the unlocking roller on the unlocking plate is a curve. This curve coincides with the swing curve of the gripper where it is pressed by the unlocking roller. This ensures that the contact point between the unlocking roller and the gripper remains unchanged during the unlocking process, avoiding relative sliding or rolling and effectively protecting the gripper surface. During the unlocking process, this mechanism only presses the gripper, without relative sliding or rolling, which can effectively protect the gripper. If the gripper is made of a soft material such as rubber, the unlocking mechanism swings to avoid it when the clamp enters or exits the clamp positioning groove. Compared with translational avoidance, this structure is easier to achieve in terms of compact size, structural stability, high precision, and improved rubber coating life.

[0015] Secondly, this invention is equipped with a product support plate, an unlocking roller, a mounting plate, a limiting block, and a spring. During the unlocking and locking process, the flexible product is always supported by the product support plate to prevent product deformation. The mounting plate is slidably connected to the unlocking plate, which can be quickly replaced according to the model of the gripper, making the operation convenient. In addition, the unlocking roller has an abutment groove to facilitate the abutment connection of the gripper, further avoiding relative sliding or rolling and protecting the surface of the gripper.

[0027] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] This invention provides an improved clamp trajectory unlocking device. The technical solution of this invention is as follows:

[0029] like Figures 1-8 As shown, a clamp track unlocking device includes a mounting frame 1. A clamp positioning groove 2 is formed on the inner wall of the mounting frame 1. A clamp assembly 4 is slidably connected to the inner wall of the clamp positioning groove 2. An unlocking assembly 3 is provided on the inner wall of the mounting frame 1. The unlocking assembly 3 includes a base plate 13, an unlocking slide plate 14, an unlocking cylinder 15, an unlocking plate 18, an unlocking roller 16, a slider 17, a track plate 19, an unlocking rotating shaft 20, a drive cylinder 8, a product support plate 21, and a cam roller 23. A movable rotating shaft 5 is provided on the bottom inner wall of the clamp positioning groove 2. The base plate 1... 3 is hinged to the movable pivot 5. Left and right positioning cylinders 6 are installed on the outer walls of the top and bottom sides of the clamp positioning groove 2. Front and rear clamping cylinders 9 are installed on the inner walls of the top sides of the clamp positioning groove 2. An ID reader 12 is installed on one outer wall of the top of the mounting frame 1. Front and rear clamping plates 10 and clamp front guide rollers 11 are fixedly connected to the heads of the front and rear clamping cylinders 9. The drive cylinder 8 is installed on the inner wall of the top of the mounting frame 1. Slide rails 22 are provided on one outer wall of the top and bottom of the base plate 13. Unlocking cylinders 15 are installed on the outer wall of the unlocking slide plate 14.

[0030] Furthermore, the unlocking slide plate 14, slider 17, and unlocking pivot 20 are all fixedly connected to the head of the unlocking cylinder 15. The slider 17 is slidably engaged with the slide rail 22. The top outer wall of the track plate 19 is provided with a track groove, and the cam rollers 23 engage with the track groove. The unlocking plate 18 is hinged to the unlocking slide plate 14 via the unlocking pivot 20. One outer wall of the unlocking plate 18 is provided with a sliding groove, and the inner wall of the sliding groove is slidably connected to a mounting plate 28. One outer wall of the mounting plate 28 is provided with several rectangular grooves, and the other outer wall of the mounting plate 28 is provided with... A connecting groove is provided, and several rotating rods 36 are slidably connected to the inner wall of the connecting groove. The rectangular grooves are all adapted to the positions of the rotating rods 36. Unlocking rollers 16 are fixedly connected to the outer walls of the rotating rods 36. Several abutting grooves 35 are opened on the outer walls of the unlocking rollers 16. The abutting grooves 35 are all arranged in a circular array and are adapted to the size of the gripper 25. The abutting grooves 35 on the unlocking rollers 16 are more adapted to the edges and corners of the gripper 25 when they abut, which facilitates locking and further avoids relative sliding or rolling, thus protecting the surface of the gripper 25.

[0031] Furthermore, the clamping assembly 4 includes a clamping frame 24 and a clamping product 26. The inner walls of both sides of the clamping frame 24 are provided with several mounting holes. The inner walls of the mounting holes are provided with grippers 25. The grippers 25 and the unlocking rollers 16 are arranged in a linear array. The grippers 25 are adapted to the positions of the unlocking rollers 16. The clamping products 26 are adapted to the size of the grippers 25. The outer wall of one side of the mounting plate 28 is provided with several limiting holes. The inner walls of the limiting holes are connected to limiting bolts 29 by threads. The limiting bolts 29 are slidably connected to the outer walls of the top and bottom ends of the rotating rod 36.

[0032] Furthermore, each of the top outer walls of the unlocking plate 18 has an installation groove, and each of the inner walls of the installation groove is fixedly connected to a support rod 34. Each of the outer walls of the support rod 34 is slidably connected to a sliding plate 32, and each of the sliding plates 32 is slidably connected to the inner wall of the installation groove. Each of the top outer walls of the sliding plate 32 is fixedly connected to a limit block 27, and each of the outer walls of one side of the limit block 27 is provided with a limit protrusion 31. Each of the top outer walls of the mounting plate 28 has a limit groove 30, and both the limit protrusion 31 and the limit groove 30 are rectangular. Each of the outer walls of the support rod 34 is fitted with a spring 33, and both ends of the spring 33 are fixedly connected to the sliding plate 32 and the unlocking plate 18, respectively. Each of the two inner walls at the bottom of the clamp positioning groove 2 is equipped with a clamp positioning sensor 7, which is located directly below the clamp frame 24. The clamp positioning sensor 7 facilitates the identification of whether the clamp assembly 4 is in position.

[0033] Working principle: When the drive cylinder 8 moves, the unlocking component 3 swings away from the clamping positioning groove 2. When the left and right positioning cylinder 6 and the front and rear clamping cylinder 9 retract, the clamping component 4 can be vertically inserted into the clamping positioning groove 2 from above. The clamping position sensor 7 can detect whether the clamping component 4 is in place. After the clamping component 4 is in place, the left and right positioning cylinder 6 moves to clamp and position the clamping component 4 from the left and right. Then, the front and rear clamping cylinder 9 moves to press and fix the clamping component 4 on the clamping positioning groove 2. After the clamping component 4 is fixed, the drive cylinder 8 moves to pull the unlocking component 3 to swing around the movable shaft 5 and approach the clamping positioning groove 2. At the same time, the product support plate 21 moves closer to the clamping product 26 with the unlocking component 3 and fits against the clamping product 26 to support the clamping product 26 flat. Then, the unlocking cylinder 15 moves. The unlocking slide plate 14 is driven to slide, and the unlocking slide plate 14 drives the unlocking plate 18 to translate and swing around the unlocking pivot 20 via the unlocking pivot 20. The unlocking roller 16 on the mounting plate 28 presses the gripper 25 to unlock the clamping assembly 4. The cam roller 23 fixed on the unlocking plate 18 cooperates with the track groove of the track plate 19 to make the movement trajectory of the unlocking roller 16 on the unlocking plate 18 a curve. This curve coincides with the swing curve of the gripper 25 where it is pressed by the unlocking roller 16. This ensures that the contact point between the unlocking roller 16 and the gripper 25 remains unchanged during the unlocking process, avoiding relative sliding or rolling and effectively protecting the surface of the gripper 25. The above action process can be reversed to lock the clamping assembly 4 and pull it out of the clamping positioning groove 2. Different grippers 25 can be adapted by replacing the track plate 19 with different guide grooves.

[0034] The mounting plate 28 is slidably connected to the slide groove on the unlocking plate 18. When the mounting plate 28 is inserted into the slide groove, the limiting block 27 is pulled to one side of the mounting groove, and the spring 33 on the outer wall of the support rod 34 is in a contracted state. When the mounting plate 28 is fully inserted into the unlocking plate 18, the limiting block 27 is released, and the sliding plate 32 is reset under the action of the spring 33. The limiting protrusion 31 on the limiting block 27 is inserted into the limiting groove 30 at the top of the mounting plate 28, and the mounting plate 28 is limited and fixed. The unlocking roller 16 is provided with an abutment groove 35, which is more suitable for its edges and corners when it abuts the gripper 25, making it easier to engage and further avoiding relative sliding or rolling, thus protecting the surface of the gripper 25.
