Description

Technical Field

[0001] This utility model relates to the field of workpiece processing technology, and more specifically to a pressing mechanism, which relates to a zero-rotation workpiece pressing mechanism. Background Technology

[0002] In the process of workpiece processing, different mechanical structures are required. In order to improve the stability of the workpiece and ensure the accuracy of the workpiece processing, the workpiece needs to be limited and fixed to prevent it from moving or slipping. Among them, the zero-rotation pressing mechanism is a mechanical device with linear pressing action as its core. It can better press and fix the workpiece. Its design feature is to ensure that there is no rotational movement at the actuator during the pressing process. The pressing and stamping operations are completed only through linear movement, which can be applied to scenarios that require high-precision linear pressing.

[0003] The existing zero-rotation workpiece pressing mechanism is only practical in scenarios with a large clamping slot. It cannot be used in situations where the product clamping slot is small, the space for convenient clamping is limited, or the constraints are not sufficient. This is not conducive to improving the practicality of the zero-rotation workpiece pressing mechanism, nor can it effectively reduce the risk of product damage. At the same time, it cannot limit the linkage structure or allow for quick assembly and disassembly, which is not conducive to improving maintenance efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a zero-rotation workpiece pressing mechanism. This mechanism solves the problem that the zero-rotation workpiece pressing mechanism can only be used in scenarios with large clamping slots, and cannot be used in situations with small product clamping slots, limited space for convenient clamping, or insufficient constraints. This is detrimental to improving the practicality of the zero-rotation workpiece pressing mechanism, and it cannot effectively reduce the risk of product damage. Furthermore, it cannot limit the linkage structure or facilitate quick assembly and disassembly, which is not conducive to improving maintenance efficiency.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a zero-rotation workpiece pressing mechanism, comprising a panel and a pressing assembly, wherein the pressing assembly is mounted on the panel and is used to fix the workpiece, the pressing assembly includes a drive plate mounted below the panel and a pull rod passing through the panel, a pressure plate is fixedly mounted above the pull rod and passes through the drive plate, a main rod located in the middle of the panel is fixedly mounted in the middle part of the drive plate, a rotating sleeve sleeved outside the pull rod passes through the drive plate, a spiral groove one and a spiral groove two are formed on the side wall of the pull rod, a pin one inserted into the rotating sleeve passes through the spiral groove one, and a pin two passes through the spiral groove two.

[0006] By adopting the above technical solution, the main rod drives the drive plate to rise, which in turn drives the slewing sleeve to rise. The slewing sleeve then drives pin one to rise. Since pin two is limited by the slewing seat, pin two can limit the lower end of the pull rod, preventing the lower end of the pull rod from rotating during its initial movement. Therefore, the rise of pin one can drive the upper telescopic end of the pull rod to rise and rotate through the spiral groove one, while the lower fixed end of the pull rod can only rotate. The rise of the pull rod drives the spiral groove two to rise, and a relative movement occurs between the spiral groove two and pin two. Then, the pull rod continues to rise. When the bottom of pin two contacts the bottom of spiral groove two, a mutual squeezing force occurs between pin one and spiral groove one. Spiral groove one can rotate along the rise of pin one. Due to the limitation of spiral groove two on the pull rod, the pull rod can rotate but not rise, thus achieving zero rotation angle.

[0007] The present invention is further configured such that: a rotary seat is installed below the panel, and the second pin is inserted into the rotary seat.

[0008] The present invention is further configured such that a sleeve is fitted over the main rod at the center of the panel.

[0009] The present invention is further configured such that a dust cover plate is fixedly installed on the panel and sleeved on the outside of the pull rod.

[0010] The present invention is further configured such that a support base is fixedly installed at the center of the upper part of the panel.

[0011] The present invention is further configured such that: a connecting component is installed below the panel, the connecting component being used to connect the panel and the rotary base.

[0012] The present invention is further configured such that: the bottom surface of the panel is symmetrically provided with screw holes one located above both sides of the rotary seat; the side wall of the rotary seat is symmetrically provided with screw holes two; the connecting assembly includes a connecting piece aligned with screw holes one and screw holes two on the same side; bolt one and bolt two are respectively inserted into screw holes one and screw holes two; and a baffle located at one end of pin two is fixedly installed below the connecting piece.

[0013] In summary, this utility model has the following beneficial effects: it can achieve the effect of zero-rotation pressing movement in conditions where the product clamping slot is small, the clamping space is small, and the constraints are not sufficient, which is conducive to improving the practicality of the zero-rotation workpiece pressing mechanism, greatly reducing the risk of product damage, and at the same time, it can achieve the effect of limiting the linkage structure and quick assembly and disassembly, which can prevent the second pin from sliding out of the rotary seat, and at the same time, it is conducive to improving maintenance efficiency.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0021] like Figure 1-2 and Figure 4As shown, panel 1 and pressing assembly 2 are mounted on panel 1. Pressing assembly 2 is used to fix the workpiece. Pressing assembly 2 includes a drive plate 201 mounted below panel 1 and a pull rod 202 passing through panel 1. The drive plate 201 can support the rotating sleeve 205. The pull rod 202 can drive the pressure plate 203 to rise and fall. The pressure plate 203 is fixedly mounted above the pull rod 202 and passes through the drive plate 201. The pressure plate 203 can press the workpiece. The middle part of the drive plate 201 is fixedly mounted with a main rod 204 located in the middle part of panel 1. The main rod 204 can pull... The drive plate 201 is raised and lowered. A rotating sleeve 205 is sleeved on the outside of the pull rod 202 inside the drive plate 201. The rotating sleeve 205 can support the first pin 206. The side wall of the pull rod 202 has a spiral groove 3 and a spiral groove 4. The spiral groove 3 and the spiral groove 4 can respectively drive the first pin 206 and the second pin 207 to connect with the pull rod 202. The first pin 206 is inserted into the rotating sleeve 205 inside the spiral groove 3. The first pin 206 can be squeezed with the spiral groove 3. The second pin 207 is inserted into the spiral groove 4. The second pin 207 can be squeezed with the spiral groove 4.

[0022] The main rod 204 drives the drive plate 201 to rise, which in turn drives the rotating sleeve 205 to rise. The rotating sleeve 205 then drives pin 1 206 to rise. Since pin 2 207 is limited by the rotating seat 5, it can limit the lower end of the pull rod 202, preventing the lower end of the pull rod 202 from rotating during its initial movement. Therefore, the rise of pin 1 206 can drive the upper telescopic end of the pull rod 202 to rise and rotate through the spiral groove 3, while the lower fixed end of the pull rod 202 can only rise and rotate. When the lever 202 rotates, it rises, causing the spiral groove 4 to rise. The spiral groove 4 rises and moves relative to the pin 207. Then the lever 202 continues to rise. When the bottom of the pin 207 contacts the bottom of the spiral groove 4, the pin 206 and the spiral groove 3 exert a mutual squeezing force. The spiral groove 3 can rotate along the rising of the pin 206. Due to the limitation of the spiral groove 4 on the lever 202, the lever 202 can rotate but cannot rise, thus achieving zero rotation angle.

[0023] like Figure 1 and Figure 3-4 As shown, a rotary seat 5 is installed below the panel 1. The rotary seat 5 can fix the second pin 207, which is inserted into the rotary seat 5.

[0024] like Figure 1 As shown, a sleeve 6 is installed at the center of the panel 1 and is fitted on the top of the main rod 204. The sleeve 6 can fix the top of the main rod 204 and can drive the top of the main rod 204 to connect with the panel 1.

[0025] like Figure 1 As shown, a dust cover 7 is fixedly installed on the panel 1 and sleeved on the outside of the pull rod 202. The dust cover 7 can protect the part where the panel 1 is connected to the pull rod 202 from dust.

[0026] like Figure 1 and Figure 4 As shown, a support base 8 is fixedly installed at the center of the upper part of the panel 1, and the support base 8 can support the product.

[0027] like Figure 3-4 As shown, a connecting assembly 9 is installed below the panel 1. The connecting assembly 9 is used to connect the panel 1 and the rotary seat 5. The bottom surface of the panel 1 has symmetrically opened screw holes 10 located above both sides of the rotary seat 5. The screw holes 10 can be connected to bolts 902. The side walls of the rotary seat 5 have symmetrically opened screw holes 11. The screw holes 11 can be connected to bolts 903. The connecting assembly 9 includes a connecting piece 901 aligned with the screw holes 10 and 11 on the same side. The connecting piece 901 can drive bolts 903. 902 is connected to bolt 903. Bolt 902 and bolt 903 are respectively inserted into screw hole 10 and screw hole 11. Bolt 902 can fix the connection between the connection 901 and screw hole 10, and bolt 903 can fix the connection between the connection 901 and screw hole 11. A baffle 904 located at one end of pin 207 is fixedly installed below the connection 901. The baffle 904 can limit the two ends of pin 207.

[0028] After pin 207 is inserted into the rotary seat 5, baffle 904 can limit the two ends of pin 207, preventing pin 207 from sliding out from both ends of the rotary seat 5. By rotating bolt 1 902 and bolt 2 903, bolt 1 902 and bolt 2 903 can be unscrewed from screw hole 1 10 and screw hole 2 11 respectively. After connecting piece 901 is no longer fixed by bolt 1 902 and bolt 2 903, it can be disassembled. At the same time, baffle 904 can be disassembled, and rotary seat 5 can be disassembled.

[0029] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
