Description

Technical Field

[0001] This utility model relates to the field of mechanical clamping technology, and more specifically, to a mechanical production clamping and feeding device. Background Technology

[0002] When assembling machinery, the production involves splicing together multiple parts. To save overall assembly time, appropriate feeding devices are often used to facilitate assembly. Currently, most feeding devices for machinery assembly consist of a feeding hopper and a lifting assembly. While these devices can meet feeding requirements, for example, a feeding device for machinery assembly disclosed in patent CN217866991U involves placing the material to be fed into the feeding hopper. Then, a multi-section hydraulic telescopic rod is activated, pushing a movable block and moving it upwards in conjunction with a guide groove and guide slider. Once the feeding height is reached, if the horizontal position is not ideal, a hydraulic cylinder can be activated to push or pull the feeding hopper. The feeding hopper then moves horizontally in conjunction with an arc-shaped sleeve, guide groove, and guide slider, thus ensuring a more precise horizontal position. Finally, the drive motor is activated, causing the horizontal support rod to rotate, thereby rotating the feeding hopper and quickly unloading the material.

[0003] When the above-mentioned device is in use, a drive motor is set up and then the horizontal support rod is connected to it. After the horizontal support rod drives the feeding hopper to rise to a specified height, it can be flipped more effectively, thereby achieving a better unloading purpose. However, when feeding mechanical workpieces of different specifications, clamping feeding is more commonly used. When using clamping feeding equipment, the chuck part is prone to damaging the mechanical workpiece when clamping and feeding relatively fragile and soft workpieces. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a mechanical production clamping and feeding device. The technical problem to be solved by the present invention is: how to facilitate the clamping and feeding equipment to clamp and feed mechanical workpieces of different specifications.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mechanical production clamping and feeding device, including a feeding bracket, including a crossbeam and support columns disposed at both ends of the crossbeam along its length;

[0006] The U-shaped limiting frame is slidably clamped on the length-height side of the crossbeam, and two clamping plates are connected to the outer side of its lower end. A strip groove is opened in the middle of the lower end of the clamping plate. An adjusting connecting plate, a rotating connecting block and a clamp are arranged in sequence from top to bottom inside the strip groove.

[0007] The chuck has a rotating support rod on its middle end face, a support slide rod on the inner side of the upper end of the chuck, an adapter slide rod in the middle of the rotating connecting block, a rotating slide sleeve at one end of the adapter slide rod, and a support spring at the other end near the adjustment knob for adjusting the clamping force. The adjustment knob is fixed to the end of the adapter slide rod for adjusting the position of the chuck.

[0008] In a preferred embodiment, a drive motor is provided on the outer side of one end of the crossbeam, and a square groove is provided on its length-height side. The output shaft of the drive motor is driven to connect to a lead screw through a coupling. The lead screw is located in the square groove and is fitted with a nut slider. A strip slider extending along the length direction of the crossbeam is provided in the square groove.

[0009] An adjusting connecting block is provided between the crossbeam and the U-shaped limiting frame. An adapter groove is provided on one side of the inner surface of the adjusting connecting block to slide with the strip slider, and the inner wall of the adapter groove is fixed to the outer side of the nut slider.

[0010] In a preferred embodiment, the adjusting connecting block has a mounting groove in the middle of its outer side, and a supporting guide rail is provided at its outer end outside the mounting groove.

[0011] The inner two walls of the U-shaped limiting frame are provided with vertical guide rail grooves, which are used to cooperate with the support guide rail to guide the movement of the U-shaped limiting frame.

[0012] In a preferred embodiment, an electric telescopic rod is provided inside the mounting groove, and a mounting ear plate is provided on the outer side of the lower end of the electric telescopic rod for connecting the adjusting connecting block. The telescopic end of the electric telescopic rod is fixedly connected to the upper side of the inner end face of the U-shaped limiting frame.

[0013] In a preferred embodiment, the upper end of the clamping plate is provided with a rotating connector, and the clamping plate is connected to the lower end of the U-shaped limiting frame through the rotating connector.

[0014] In a preferred embodiment, both ends of the adjusting connecting plate are provided with hinges, one end of which is connected to the output shaft of the clamping electric telescopic rod via a hinge, and the other end is movably connected to the inner side of the strip groove via a hinge. The clamping electric telescopic rod is installed on the inner side of the U-shaped limiting frame.

[0015] In a preferred embodiment, the adapter slide has an adjustment knob at the end away from the rotating slide sleeve.

[0016] In a preferred embodiment, the lower end of the support column is provided with a mounting base.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] In practical use, this invention allows for the adjustment and control of the spring force of the support spring by rotating the adjustment knob in the corresponding configuration of the chuck, rotating connecting block, rotating sliding sleeve, adapter slide rod, support spring, adjusting knob, and support slide rod. Simultaneously, when the rotating sliding sleeve and support slide rod are in the compatible configuration, the lower end of the chuck contacts the workpiece during clamping and loading. The clamping force pulls the adapter slide rod outwards, while the support spring, resisting the force generated by the rotating connecting block and adjusting knob, pulls the adapter slide rod in the opposite direction. This ensures stable contact between the chuck and the workpiece. Furthermore, rotating the adjusting knob allows for adjustment and control of the spring force of the support spring, facilitating the clamping of workpieces of different specifications and enabling the loading of even fragile and soft workpieces.

[0024] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided so that the description of this disclosure will be more complete and fully convey the concept of the exemplary embodiments to those skilled in the art. The drawings are merely illustrative of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted.

[0025] Furthermore, the described features, structures, or characteristics can be combined in any suitable manner in one or more exemplary embodiments. Numerous specific details are provided in the following description to give a full understanding of exemplary embodiments of this disclosure. However, those skilled in the art will recognize that the technical solutions of this disclosure can be practiced with one or more of the specific details omitted, or other methods, components, steps, etc., can be employed. In other instances, well-known structures, methods, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of this disclosure.

[0026] This utility model provides a mechanical production clamping and feeding device, such as... Figure 1 and 2 As shown, it includes a feeding bracket 1, a crossbeam 101 and support columns 102 disposed at both ends of the crossbeam 101 along its length; and a U-shaped limiting bracket 6, which is slidably clamped on the length-height side of the crossbeam 101 along its length, and has two clamping plates 11 connected to the outer side of its lower end.

[0027] A drive motor 3 is provided on the outer side of one end of the crossbeam 101. A square groove 4 is provided on its length-height side. The output shaft of the drive motor 3 is connected to a lead screw 7 via a coupling. The operator can drive the drive motor 3 to work through an external control device. The output shaft of the drive motor 3 will drive the adjusting connecting block 8 to adjust and control its position through the lead screw 7. The lead screw 7 is located in the square groove 4 and is fitted with a nut slider. A strip slider 5 extending along the length direction of the crossbeam 101 is provided in the square groove 4.

[0028] An adjusting connecting block 8 is provided between the crossbeam 101 and the U-shaped limiting frame 6. An adaptation groove 13 is provided on one side of the inner surface of the adjusting connecting block 8 to slide with the strip slider 5. The inner wall of the adaptation groove 13 is fixed to the outer side of the nut slider. When the strip slider 5 is in the adaptation state with the adaptation groove 13, the stability of the movement of the adjusting connecting block 8 can be effectively increased.

[0029] The adjusting connecting block 8 has a mounting groove 15 in the middle of its outer side, and a support guide rail 14 is provided at its outer end outside the mounting groove 15.

[0030] The U-shaped limiting frame 6 has vertical guide rail grooves 12 on its inner two walls, which are used to cooperate with the support guide rail 14 to guide the movement of the U-shaped limiting frame 6. The mounting groove 15 is provided with an electric telescopic rod 10.

[0031] The lower outer side of the electric telescopic rod 10 is provided with a mounting ear plate 16 for connecting the adjusting connecting block 8. The telescopic end of the electric telescopic rod 10 is fixedly connected to the upper side of the inner end face of the U-shaped limiting frame 6. The clamping electric telescopic rod 9 is installed on the inner side of the U-shaped limiting frame 6. The lower end of the support column 102 is provided with a mounting base 2. The operator can drive the electric telescopic rod 10 to work through an external control device, which will drive the U-shaped limiting frame 6 to lift and lower through the output shaft, thereby increasing the convenience of loading and unloading workpieces.

[0032] like Figure 3 and 4 As shown, a strip groove 18 is provided in the middle of the lower end of the clamping plate 11. The inside of the strip groove 18 is provided with an adjusting connecting plate 19, a rotating connecting block 22 and a clamp 20 from top to bottom. A rotating support rod 21 is provided on the middle end face of the clamp 20.

[0033] The upper end of the chuck 20 is provided with a support slide rod 27 on the inner side, and the middle part of the rotating connecting block 22 is provided with an adapter slide rod 24, which can facilitate the sliding of the adapter slide rod 24 inside the rotating connecting block 22. One end of the adapter slide rod 24 is provided with a rotating slide sleeve 23, and the other end is provided with a support spring 25 near the adjusting knob 26 for adjusting the clamping force.

[0034] The adjustment knob 26 is fixed to the end of the adapter slide rod 24 and is used to adjust the position of the chuck 20. The upper end of the clamping plate 11 is provided with a rotating connector 17. The lower end of the clamping plate 11 and the U-shaped limiting frame 6 are connected through the rotating connector 17. The operator installs the rotating sleeve 23 on the outer end face of the support slide rod 27. So that after the chuck 20 comes into contact with the workpiece, the clamping force will react on the support slide rod 27, thereby causing the support slide rod 27 to drive the adapter slide rod 24 to move through the rotating sleeve 23.

[0035] Both ends of the adjusting connecting plate 19 are provided with hinges. One end is connected to the output shaft of the clamping electric telescopic rod 9 via a hinge, and the other end is movably connected to the inner side of the strip groove 18 via a hinge. The adapter slide rod 24 is provided with an adjusting knob 26 at the end away from the rotating slide sleeve 23. When the adapter slide rod 24 is moved to one side by an external force, the provided support spring 25 will press against the adjusting knob 26 and the rotating connecting block 22 to tighten the adapter slide rod 24. This will pull the chuck 20 through the rotating slide sleeve 23, making the lower end of the chuck 20 fit more stably with the outer end face of the workpiece, thus facilitating the clamping and feeding of relatively fragile workpieces. At the same time, the support range of the support spring 25 can be adjusted by rotating the adjusting knob 26, so that the clamping degree of the support spring 25 can be adjusted according to different workpiece specifications.

[0036] The operator can drive the electric telescopic clamping rod 9 to work through the external control device. The output shaft will pull the adjusting connecting plate 19 to adjust the height. When the output shaft of the electric telescopic clamping rod 9 descends, it can push the adjusting connecting plate 19 to open outward. When the adjusting connecting plate 19 opens outward, it can control the clamping plate 11 to open outward. When the output shaft of the electric telescopic clamping rod 9 rises, it will pull the clamping plate 11 to retract inward through the adjusting connecting plate 19, thereby facilitating the clamping plate 11 to clamp the workpiece.
