Abstract
Description
Technical Field
[0001] This utility model belongs to the field of industrial processing equipment, and specifically relates to a clamping device for packaging parts. Background Technology
[0002] In the industrial production process, when packaging the formed parts, they need to be individually clamped and moved to the packaging box or bag for subsequent sealing. In order to reduce manual labor and improve packaging efficiency, automated clamping devices are now widely used in workshops to individually clamp the parts.
[0003] Chinese Patent CN208929619U discloses a clamping mechanism for parts in an automatic assembly machine, including a clamp, a cylinder, a connecting block, a transmission component, a guide slide rod, and sliding pins. The clamp includes a left clamp and a right clamp, both with horizontal top surfaces and vertical sidewalls. The connecting block is fixedly connected to the cylinder and embedded in the transmission component. The guide slide rod is sequentially inserted through sliding connection holes on the right clamp to connect the left and right clamps. Two sliding pins pass through figure-eight sliding guide holes on the transmission component and are fixed to the left and right clamps, respectively. This invention ensures that the clamping action is smooth and makes surface contact with the parts, resulting in even force distribution and reducing the risk of damage. It also effectively solves the problem of insufficient or excessive clamping causing deformation or damage to parts, thus reducing the production damage rate of automatic assembly machines.
[0004] The above technical solution has the following drawbacks:
[0005] It can provide stable clamping for workpieces or parts with traditional shapes, but it cannot clamp ring-shaped workpieces properly (because the ring surface will slip, making it difficult to clamp).
[0006] Therefore, a clamping device is needed that can stably clamp both block-shaped (square or polygonal) industrial parts and ring-shaped industrial parts. Utility Model Content
[0007] To address the above deficiencies, this utility model provides a clamping device for packaging parts, including a connecting seat and several cylinder grippers installed on the connecting seat. The top of the connecting seat has a fixing groove for installation, and the inside of the fixing groove has symmetrical slots. The slots are fixed by matching connecting pins and fixing rings. A set of slide rails is installed on all four sides of the connecting seat. The slide rails on the front and rear sides are equipped with matching electric sliders, and the slide rails on the left and right sides are equipped with matching linkage sliders. The tops of each electric slider and linkage slider are connected by an installed linkage frame. The electric slider is fixed to the cylinder grippers by a fixed connecting rod.
[0008] It also includes a triangular seat located at the bottom of the connecting seat. The triangular seat is movably connected to a screw groove opened at the bottom of the connecting seat by a screw fixed at the top. A single lug connector is fixed at the middle of the top of each of the three sides of the triangular seat. Each single lug connector is hinged to a linkage rod by a pin. The middle of each linkage rod is hinged to an electric push rod installed at the middle of the three sides of the triangular seat by a pin. The bottom end of each linkage rod is hinged to an inner support plate by a spring pin.
[0009] Furthermore, the outer side of the triangular base is provided with a retaining ring for limiting the linkage rod, and the inner ring of the retaining ring is fixed to the three corners of the triangular base by three connecting rods respectively.
[0010] Furthermore, the initial vertical position of the cylinder gripper is located outside the retaining ring.
[0011] Furthermore, the inner support plate is curved, and a rubber pad is fixed to the clamping surface.
[0012] Compared with the prior art, the present invention has the following advantages:
[0013] The cylinder gripper at the connecting seat can grip traditional square parts, while the movable triangular seat can grip annular parts with an internal support. After assembly, it does not need to be disassembled. The position of the cylinder gripper can be adjusted by an electric slider. When it moves down, it can perform traditional gripping, and when it moves up, it is located at the top of the internal support plate, which does not affect the gripping of annular parts by the internal support plate.

[0016] To facilitate understanding of this utility model, the device of this utility model will be described more fully below with reference to the accompanying drawings. Embodiments of the device are shown in the drawings. However, this device can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.
[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0018] Example
[0019] like Figure 1 As shown, this embodiment provides a clamping device for packaging parts, including a connecting seat 1 and a plurality of cylinder grippers 11 installed on the connecting seat 1. The top of the connecting seat 1 is provided with a fixing groove 5 for installation. The fixing groove 5 is provided with symmetrical slots inside, and the slots are fixed by a matching connecting pin 3 and a fixing ring 4. It can be installed on the top of a lathe or equipment rack. That is, after the connecting pin 3 is inserted into the fixing groove on the top of the lathe or equipment rack, the connecting seat 1 is suspended. Then, the two ends of the connecting pin 3 are inserted and fixed by the fixing ring 4 (a nut and bolt structure can be used).
[0020] A set of slide rails 6 is installed on all four sides of the connecting seat 1. The slide rails 6 on the front and rear sides are equipped with matching electric sliders 8 (which need to meet the requirements of synchronous and unidirectional movement, which can be set by the PLC controller). The slide rails 6 on the left and right sides are equipped with matching linkage sliders 7. The tops of each electric slider 8 and linkage slider 7 are connected by the installed linkage frame 9. The electric slider 8 is fixed with a cylinder gripper 11 by inserting a fixed connecting rod 10. It should be noted that in this embodiment, only the electric slider 8 is equipped with a cylinder gripper 11 (using a GFR single-acting finger cylinder). Additional cylinder grippers 11 can be added to the other two linkage sliders 7 as needed. The specific addition or subtraction can be made according to the actual situation, which will not be elaborated here.
[0021] It also includes a triangular seat 2 located at the bottom of the connecting seat 1. The triangular seat 2 is movably connected to the threaded groove opened at the bottom of the connecting seat 1 by a screw 12 fixed at the top. A single lug connector is fixed at the middle of the top of each of the three sides of the triangular seat 2. Each single lug connector is hinged to a linkage rod 13 by a pin. The middle of each linkage rod 13 is hinged to an electric push rod 14 installed at the middle of the three sides of the triangular seat 2 by a pin (it needs to meet the requirements of synchronous and unidirectional movement, which can be set by a PLC controller). The bottom end of each linkage rod 13 is hinged to an inner support plate 16 by a spring pin. The spring pin can make the inner support plate 16 return to its original position after the inner support is removed. The inner support plate 16 is an arc surface and the clamping surface is fixed with a rubber pad, which can effectively prevent wear of the parts.
[0022] Additionally, the outer side of the triangular base 2 is provided with a retaining ring 15 for limiting the linkage rod 13. The inner ring of the retaining ring 15 is fixed to the three corners of the triangular base 2 by three connecting rods respectively.
[0023] The component packaging clamping device described in this embodiment controls the electric slider 8 to move down when clamping a traditional square component, and then controls the cylinder gripper 11 to clamp the component. When clamping a ring-shaped component, the electric slider 8 is controlled to move up so that it is located at the top of the protective ring 15, and then each electric push rod 14 is controlled to extend synchronously, driving the hinged linkage rod 13 to extend outward, so that the bottom inner support plate 16 supports the inner ring of the ring-shaped component, thereby realizing the clamping operation.
[0024] It should be noted that the structure described in this utility model can be implemented in many different forms and is not limited to the embodiments described. Any equivalent transformations made by those skilled in the art based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, such as the loading and unloading of other items, are included within the protection scope of this utility model.
