[0002] A screw batch gripping device is a specialized device designed for the efficient and stable gripping and handling of screws. It is widely used in screw processing and production. Its main function is to automate the gripping, moving and placing of screws through mechanical devices. Precise control reduces human error, making the screws more stable during batch gripping and reducing the risk of them falling, thereby improving production efficiency and processing quality.
[0003] Based on the above, the inventors have discovered the following shortcomings in existing bulk screw gripping devices:
[0004] 1. The contact surface of the gripping plate is flat, which makes it easy for the gripped screw to be bent. It is not convenient to set a contact structure on the gripping plate to prevent the screw from bending and to make it suitable for different screw diameters.
[0005] 2. The gripping plate is a flip-type gripper, which creates an angle during opening and closing, resulting in uneven gripping force. It is inconvenient to add a moving opening and closing mechanism to the device so that the gripping plate can move horizontally to open and close for gripping. Utility Model Content
[0006] To address the aforementioned technical problems, this utility model provides a batch screw gripping device. This addresses the issues of existing gripping plates having a planar contact surface, which makes it easy for gripped screws to become misaligned, and the inconvenience of adding contact structures to the gripping plate to prevent misalignment and to accommodate different screw diameters; and the gripping plate being a flip-type design, which creates an angle during opening and closing, leading to uneven gripping force, and the inconvenience of adding movable opening and closing mechanisms to the device to allow the gripping plate to move horizontally for gripping.
[0007] The purpose and effectiveness of this utility model screw batch gripping device are achieved by the following specific technical means:
[0008] A screw batch gripping device includes a device body; the device body is provided with a double-plate gripping rod in the front-back direction, and gripping plates in the front-back direction are provided on the upper and lower sides of the left end face of the double-plate gripping rod. The left end face of the gripping plates of the double-plate gripping rod has three V-shaped grooves arranged in a front-back and vertically through manner. The rear end of the double-plate gripping rod has a square hole that passes through from left to right. The middle of the rear end face of the double-plate gripping rod has a limiting groove that passes through from left to right. The rear end of the double-plate gripping rod has a fixing hole that passes through from top to bottom.
[0009] Furthermore, an opening and closing linkage rod in the front-to-back direction is installed inside the limiting groove of the opening and closing movable plate via a fixed shaft. Both ends of the opening and closing linkage rod are provided with semi-circular heads with through holes at the top and bottom. The front end of the opening and closing linkage rod on the right side of the opening and closing movable plate is installed inside the limiting groove of the double-plate gripping rod via a fixed shaft, and the front end of the opening and closing linkage rod on the left side of the opening and closing movable plate is installed inside the limiting groove of the single-plate gripping rod via a fixed shaft.
[0010] Furthermore, the outer circumference of the opening and closing rotating rod is threaded with a left-right opening and closing moving plate. The opening and closing moving plate has a threaded hole that runs through the front and back in the middle. The left and right end faces of the opening and closing moving plate are both provided with a limiting groove that runs through the front and back. The left and right ends of the opening and closing moving plate are both provided with a fixing hole that runs through the top and bottom.
[0011] Furthermore, a fixed post is provided on the front end face of the opening and closing rotating rod, and a regular hexagonal prism is provided on the rear end face of the opening and closing rotating rod.
[0012] Furthermore, an opening and closing rotating rod is mounted in the rear of the fixed cylinder of the opening and closing guide rod via a bearing, and the outer circumference of the opening and closing rotating rod is threaded.
[0013] Furthermore, a left-right opening and closing guide rod is inserted between the square holes of the double-plate gripping rod and the single-plate gripping rod. A fixed cylinder that runs through the front and back is provided in the middle of the opening and closing guide rod, and fixed holes that run through the top and bottom are provided at both ends of the opening and closing guide rod.
[0014] Furthermore, a single-plate gripping rod is inserted on the left side between the gripping plates of the double-plate gripping rod, and a gripping plate in the front-back direction is set in the middle of the right end face of the single-plate gripping rod.

[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] The screw is conveniently located inside the V-groove between the double-plate gripping rod and the single-plate gripping rod. This allows the screw to be easily positioned and prevented from tilting by using the V-groove between the double-plate gripping rod and the single-plate gripping rod. This solves the problem that the contact surface of the gripping plate is flat, which makes it easy for the gripped screw to be tilted. It also makes it inconvenient to set a contact structure on the gripping plate to prevent the screw from tilting and to make it suitable for different screw diameters.
[0017] The convenient opening and closing rotating rod is mounted on the opening and closing guide rod via bearings to support the opening and closing moving plate. The convenient opening and closing moving plate is connected to the double-plate gripping rod and the single-plate gripping rod via the opening and closing linkage rod. This allows the double-plate gripping rod and the single-plate gripping rod to move synchronously inward or outward along the opening and closing guide rod. This solves the problem that the gripping plate is flip-type, which will form an angle during the opening and closing process, resulting in uneven gripping force and making it inconvenient to add moving opening and closing measures to the device so that the gripping plate can move horizontally to open and close for gripping.

[0029] The double-plate gripping rod 2 and the single-plate gripping rod 3 are connected by a left-right opening and closing guide rod 4, which facilitates the movement and guidance of the double-plate gripping rod 2 and the single-plate gripping rod 3. A through-hole fixing cylinder is provided in the middle of the opening and closing guide rod 4, which facilitates the installation of the opening and closing rotating rod 5 via bearings. Both ends of the opening and closing guide rod 4 have through-hole fixing holes, which facilitate the fixing of the opening and closing guide rod 4 with bolts. The front and rear sides of the fixing cylinder of the opening and closing guide rod 4 are connected by bearings to install the front and rear sides of the opening and closing rotating rod 5, which facilitates the rotation of the opening and closing rotating rod 5. The outer circumference of the opening and closing rotating rod 5 is threaded, which facilitates the installation of the opening and closing moving plate 6 via threads. A fixing post is provided on the front end face of the opening and closing rotating rod 5, which facilitates the installation of the opening and closing guide rod 4 via bearings. The rear end face of the opening and closing rotating rod 5 is provided with a regular hexagonal prism, which facilitates synchronous rotation with an external power device. The outer circumference of the opening and closing rotating rod 5 is threaded with a left-right opening and closing moving plate 6, which facilitates the front and rear movement of the opening and closing moving plate 6 via threaded engagement. A through-hole is provided in the middle to facilitate the threaded installation of the opening and closing rotating rod 5. Both ends of the opening and closing moving plate 6 have through-holes for easy insertion of the opening and closing linkage rod 7. Both ends of the opening and closing moving plate 6 have through-holes for easy installation of the opening and closing linkage rod 7 via a fixed shaft.

The front end of the opening and closing linkage rod 7 on the left side of the opening and closing moving plate 6 is installed inside the limiting groove of the single-plate gripping rod 3 via a fixed shaft, which facilitates the opening and closing moving plate 6 to drive the single-plate gripping rod 3 to move in and out through the opening and closing linkage rod 7.
[0030] The specific usage and function of this embodiment are as follows:
[0031] In this utility model, such as Figure 1 As shown, the double-plate gripping rod 2 and the single-plate gripping rod 3 are in the closed state. When the double-plate gripping rod 2 and the single-plate gripping rod 3 are opened, the regular hexagonal prism of the opening and closing rotating rod 5 is connected synchronously with the external power device. The two ends of the opening and closing guide rod 4 are fixed with bolts. The external power device drives the opening and closing rotating rod 5 to rotate, so that the opening and closing rotating rod 5 rotates and engages with the opening and closing moving plate 6 through the threaded engagement. The opening and closing moving plate 6 drives the rear end of the opening and closing linkage rod 7 to move forward synchronously, so that the front end of the opening and closing linkage rod 7 moves outward. The front end of the opening and closing linkage rod 7 drives the double-plate gripping rod 2 and the single-plate gripping rod 3 to move outward synchronously, as shown in the figure. Figure 3As shown, this opens the double-plate gripping rod 2 and the single-plate gripping rod 3. Then, the screw is positioned inside the V-groove between the double-plate gripping rod 2 and the single-plate gripping rod 3. An external power device drives the opening / closing rotating rod 5 to rotate, causing it to engage with the threaded opening / closing moving plate 6. The opening / closing moving plate 6 moves backward through this threaded engagement, simultaneously driving the rear end of the opening / closing connecting rod 7 backward. This causes the front end of the opening / closing connecting rod 7 to move inward, which in turn drives both the double-plate gripping rod 2 and the single-plate gripping rod 3 to move inward simultaneously. The state is as follows. Figure 4 As shown, this enables the double-plate gripping rod 2 and the single-plate gripping rod 3 to grip the screw. The number of V-grooves in the double-plate gripping rod 2 and the single-plate gripping rod 3 can be increased or decreased according to actual needs.
[0032] Example 2:
[0033] The difference from Embodiment 1 is that the inner surface of the V-groove of the double-plate gripping rod 2 can also be set as a frosted surface, thereby increasing the friction between the inner surface of the V-groove of the double-plate gripping rod 2 and the screw, making the double-plate gripping rod 2 grip the screw more firmly.
[0034] Example 3:
[0035] The difference from Embodiment 1 is that the inner surface of the V-groove of the single board gripping rod 3 can also be set as a frosted surface, thereby increasing the friction between the inner surface of the V-groove of the single board gripping rod 3 and the screw, making the gripping rod 3 of the screw more secure.
