[0001] The utility model relates to the technical field of mechanical equipment, in particular to a one-way clamping and feeding chuck. Background Art

[0002] In an automated production line, it is very important to accurately control the position of materials. At present, many processing equipment adopt the conveyor belt type to convey materials. The conveyor belt usually consists of a conveyor belt, a driving device, a driving roller, a supporting roller, a tensioning device, etc. It is suitable for transporting small parts or finished products. The conveyor belt runs stably and can meet the material conveying requirements of most production lines.

[0003] In the scenario where the traditional conveyor belt is used to convey materials and needs to be processed and matched with materials such as drilling, it is easy to have inaccurate conveying positions, and it is impossible to achieve rapid intermittent advancement of materials, resulting in inaccurate drilling positions. This will increase the on-site debugging work of staff and increase the scrap rate of materials, and cannot meet the requirements of high-precision fixed-distance material transfer. In view of the deficiencies of the prior art, the utility model provides a one-way clamping and feeding chuck to solve the above problems. Summary of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a one-way clamping and feeding chuck. When the whole device conveys materials, it realizes clamping when the device advances the materials and loosening the materials when the device retreats. Therefore, the device can accurately control the position and speed of the materials, intermittently advance the materials during the process of processing materials on the automated production line, ensure the accurate processing position of the materials, reduce the on-site debugging work of personnel, reduce the scrap rate, and meet the requirements of high-precision fixed-distance material transfer.

[0021] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model are described clearly and completely. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] By providing a one-way clamping and feeding chuck in the embodiments of the present application, the problems that in the scenario where the traditional conveyor belt is used to convey materials and processing operations such as drilling the materials are required, the conveying position is prone to be inaccurate, the materials cannot be intermittently advanced quickly, resulting in inaccurate drilling positions, which will increase the on-site debugging work of the staff and the rejection rate of the materials, and cannot meet the requirement of high-precision fixed-distance material transfer are solved.

[0023] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0024] The embodiments of the present utility model disclose a one-way clamping and feeding chuck. As shown in the attached Figures 1-4 figure, it includes a horizontal guide rail seat 2 provided on a positioning bracket 1 and a first electric push rod 21 provided on the horizontal guide rail seat 2. A reciprocating slider 22 is provided at the output end of the first electric push rod 21;

[0025] A material limiting seat 11 is provided on the positioning bracket 1. The device realizes the bilateral limitation of the material through the design of the material limiting seat 11, so that the conveyance of the material is stable. A vertical guide rail seat 3 is fixedly connected to the reciprocating slider 22;

[0026] A gear 31 is rotatably connected to the vertical guide rail seat 3. A first rack 32 and a second rack 33 are respectively meshed and connected on both sides of the gear 31. The first rack 32 and the second rack 33 are slidably connected to the vertical guide rail seat 3;

[0027] A second electric push rod 34 is provided on the vertical guide rail base 3. The second electric push rod 34 is connected to the first rack 32. Support arms 4 are connected to both the first rack 32 and the second rack 33. A chuck plate 5 is movably clamped on the support arm 4. A limit sleeve base 35 for providing a limit to the support arm 4 is provided on the vertical guide rail base 3. The provided limit sleeve base 35 limits the support arm 4 to ensure the stable position of the support arm 4.

[0028] For this one-way clamping and feeding chuck, the positioning bracket 1 is used to support and limit the whole device. Among them, the horizontal guide rail base 2 supports the first electric push rod 21. When it is necessary to use this device to perform one-way clamping and conveying of materials, the first electric push rod 21 drives the reciprocating slider 22 to perform reciprocating motion. During the forward movement of the reciprocating slider 22, the two chuck plates 5 clamp the material, thereby driving the material forward. When the reciprocating slider 22 moves backward, the two chuck plates 5 do not contact the surface of the material, so that the material remains stationary. Therefore, the material is continuously and intermittently pushed forward, which is convenient for the processing of the material.

[0029] The movement control of the two chuck plates 5 is powered by the second electric push rod 34. Through the design of the gear 31, the first rack 32 and the second rack 33, the movement directions of the first rack 32 and the second rack 33 are opposite. Therefore, the movement directions of the two support arms 4 and the chuck plates 5 are opposite, ensuring the stable clamping process of the material.

[0030] When the second electric push rod 34 works, it drives the first rack 32 to move. The first rack 32 drives the gear 31 to rotate. The gear 31 drives the second rack 33 to move, and then the two support arms 4 and the chuck plates 5 move synchronously to realize the clamping of the material by the two chuck plates 5.

[0031] A sleeve base 41 is provided on the support arm 4. A clamping block 51 is provided on the chuck plate 5. The clamping block 51 is movably clamped in the sleeve base 41. Through the design of the clamping block 51 and the sleeve base 41, the disassembly and assembly of the chuck plate 5 are convenient. Therefore, the chuck plate 5 is easy to replace different models to adapt to different material clamping and feeding uses.

[0032] A locking mechanism 6 is provided on the sleeve base 41. The locking mechanism 6 includes a hollow seat 61 fixedly connected to the sleeve base 41. A slider 62 is slidably connected inside the hollow seat 61. A locking rod 63 is provided on the slider 62. A locking hole 511 is provided on the clamping block 51. The locking rod 63 is movably clamped in the locking hole 511. A spring 64 is fixedly connected between the slider 62 and the hollow seat 61.

[0033] Through the design of the locking mechanism 6, after the clamping block 51 and the socket 41 are clamped, their positions can be quickly locked, making the disassembly and assembly of the chuck plate 5 convenient and the installation stable. When installing the chuck plate 5, first move the slider 62 and the locking rod 63 as a whole and compress the spring 64. At this time, clamp the clamping block 51 and the socket 41. After complete clamping, the chuck plate 5 is in place. Finally, release the slider 62 and the locking rod 63, and the spring 64 resets and pushes the slider 62 and the locking rod 63 to move, so that the locking rod 63 is inserted into the inside of the locking hole 511 to complete the quick installation of the chuck plate 5.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
