Description

Technical Field

[0001] The present invention relates to the technical field of mechanical manufacturing, and more specifically to a fixture, which relates to a special fixture for an anti-collision moving disk. Background Technique

[0002] A special fixture for a moving disk is a device used to fix and clamp a moving disk. There are a wide variety of special fixtures for moving disks, including special fixtures for milling the profile of a scroll moving disk and robot fixtures for automotive driven disks. Special fixtures for moving disks have the advantages of improving the accuracy, processing efficiency, and processing stability during the processing of moving disks, being able to facilitate mechanized and assembly-line work, and simultaneously being able to better reduce the loss rate during processing.

[0003] When the existing special fixture for a moving disk is in use, it can only be clamped by a 90° moving disk fixture. During the clamping process, due to the small space of the product clamping notch, it cannot be used under the conditions of a small clamping space and insufficient limiting conditions, which is not conducive to fully reducing the risk of product collision damage and cannot complete the clamping. At the same time, it cannot fully reduce the friction between the pressure plate and the product, easily causing the problem of rapid wear of the pressure plate, which is not conducive to reducing the probability of pressure plate replacement and is not conducive to reducing the use cost. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a special fixture for an anti-collision moving disk, which can solve the problems that the existing special fixture for a moving disk cannot be used under the conditions of a small clamping space and insufficient limiting conditions, is not conducive to fully reducing the risk of product collision damage, and at the same time cannot fully reduce the friction between the pressure plate and the product, easily causing the problem of rapid wear of the pressure plate, which is not conducive to reducing the probability of pressure plate replacement and is not conducive to reducing the use cost.

[0005] The above technical purpose of the present invention is achieved through the following technical solutions: A special fixture for an anti-collision moving disk includes a panel and a zero-rotation angle clamping assembly. The zero-rotation angle clamping assembly is installed on the panel. The zero-rotation angle clamping assembly includes a fixing member and a power member. The fixing member includes three pull rods evenly penetrating through the panel. A pressure plate located above the panel is fixedly installed above each of the pull rods. A first spiral groove and a second spiral groove are respectively formed on the side walls of each of the pull rods. A first driving pin and a second driving pin are respectively inserted into the first spiral groove and the second spiral groove. The power member includes a driving plate installed at the central part below the panel and sleeved outside each of the pull rods. A driving rod is fixedly installed at the central part of the driving plate. Three rotating sleeves respectively sleeved outside each of the pull rods are fixedly inserted into the driving plate. Each of the rotating sleeves is sleeved outside each of the first driving pins. A driving piston is fixedly installed directly below the driving rod.

[0006] By adopting the above technical solution, the panel can fix the swivel base, and at the same time, the panel can limit the pull rod in the horizontal direction, preventing the pull rod from moving horizontally. When it is necessary to press and clamp the product for fixation, by starting the driving piston, the driving piston pushes the driving rod upward. The upward movement of the driving rod can drive the swivel sleeve upward, the upward movement of the swivel sleeve can drive the driving plate upward, the upward movement of the driving plate can drive the swivel sleeve upward, the upward movement of the swivel sleeve can drive the driving pin 1 upward, and the upward movement of the driving pin 1 can squeeze the spiral groove 1. The force on the spiral groove 1 after being squeezed by the driving pin 1 can be divided into a horizontal component force and a vertically upward component force. Since the driving pin 2 is fixed by the swivel base and remains stationary, and the driving pin 2 is located in the vertical structure inside the spiral groove 2, the driving pin 2 can limit the spiral groove 2. At this time, the driving pin 2 can prevent the spiral groove 2 from rotating in the horizontal plane. After the spiral groove 2 is limited, it can limit the pull rod. Therefore, the pull rod can only move up and down and cannot rotate in the horizontal plane. The horizontal component force and the vertically upward component force received by the spiral groove 1 can be transmitted to the pull rod. Therefore, after the pull rod is limited, it can only rise. The rise of the pull rod can drive the pressure plate to rise. The driving piston continuously drives the driving rod to rise. At this time, the driving pin 2 moves to the lower horizontal structure of the spiral groove 2. At this time, the spiral groove 2 loses the horizontal direction limit. Therefore, the pull rod loses the horizontal direction limit. However, the vertical movement of the spiral groove 2 is limited by the driving pin 2. Therefore, the spiral groove 2 can only rotate in the horizontal plane sleeved outside the driving pin 2. After the pull rod is limited by the spiral groove 2, it can only rotate around its own central axis in the horizontal plane. Therefore, the horizontal component force received by the spiral groove 1 can drive the pull rod to rotate around its own central axis in the horizontal plane. Relative torsion occurs between the spiral groove 1 and the driving pin 1. The pull rod can drive the pressure plate to rotate in the horizontal plane. The pressure plate can clamp and fix the product placed on the support seat, effectively improving the safety of product processing. By driving the pull rod to move up and down through the driving plate, the cooperation of the driving pin 2 and the spiral groove 2 is used to eliminate the rotation action. The swivel base is connected to the panel, and the rotation direction is controlled by the cooperation of the driving pin 2 and the spiral groove 2, so that the pull rod rotates without rising action, thereby realizing a zero rotation angle.

[0007] The present invention is further configured such that: three swivel seats are fixedly installed below the panel, and each of the three swivel seats is sleeved at both ends of each of the driving pins 2.

[0008] The present invention is further configured such that: a guide rod is penetrated through one side of the driving piston.

[0009] The present invention is further configured such that: a support seat is fixedly installed at the middle part above the panel, and an angular pin and an anti-misalignment key are respectively installed above and on the side wall of the support seat.

[0010] The present invention is further configured such that a dust-proof cover plate fixedly installed above the panel is sleeved outside each of the pull rods.

[0011] The present invention is further configured such that a first cover plate fixedly sleeved outside the drive rod is fixedly installed at the middle part of the drive plate.

[0012] The present invention is further configured such that a second cover plate fixedly connected to the bottom surface of the guide rod is installed below the drive piston.

[0013] The present invention is further configured such that a positioning body sleeved outside the zero-rotation-angle clamping assembly is fixedly installed below the panel.

[0014] The present invention is further configured such that a transition plate fixedly connected to the bottom surface of the second cover plate is fixedly installed below the positioning body.

[0015] The present invention is further configured such that guide slide rails are provided below each of the pressing plates, and a plurality of arranged guide steel balls are installed in each of the guide slide rails.

[0016] In summary, the present invention has the following beneficial effects: By using the zero-rotation-angle clamping assembly and the guide steel balls, it is possible to achieve the effect of use under the conditions of a small clamping space at the clamping notch of the product and insufficient limiting conditions. Through the action of the zero-rotation angle, it is beneficial to fully reduce the risk of product collision damage, facilitate rapid clamping, and at the same time can achieve the effect of fully reducing the friction between the pressing plate and the product, prevent the pressing plate from being quickly worn, is beneficial to reducing the probability of pressing plate replacement, and greatly reduces the use cost.

Detailed implementation manners

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] Among them, the same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component respectively.

[0025] As Figures 1-5As shown in the figure, it includes a panel 1 and a zero-rotation-angle clamping assembly 2. The zero-rotation-angle clamping assembly 2 is installed on the panel 1. The zero-rotation-angle clamping assembly 2 includes a fixing member and a power member. The fixing member includes three pull rods 201 evenly penetrating through the panel 1. The pull rods 201 can support the pressure plate 202, and at the same time, the pull rods 201 can drive the pressure plate 202 to move up and down. Above each pull rod 201, a pressure plate 202 located above the panel 1 is fixedly installed. The pressure plate 202 can press and fix the product. A first spiral groove 3 and a second spiral groove 4 are respectively formed on the side walls of each pull rod 201. The first spiral groove 3 and the second spiral groove 4 can respectively drive the connection between the first driving pin 203 and the second driving pin 204 and the pull rod 201. The first driving pin 203 and the second driving pin 204 are respectively inserted into the first spiral groove 3 and the second spiral groove 4. The first driving pin 203 and the second driving pin 204 can respectively drive the pull rod 201 to rotate and move up and down through the first spiral groove 3 and the second spiral groove 4. The power member includes a driving plate 205 installed at the central part below the panel 1 and sleeved outside each pull rod 201. The driving plate 205 can support the rotary sleeve 207. A driving rod 206 is fixedly installed at the central part of the driving plate 205. The driving rod 206 can drive the driving plate 205 to move up and down. Three rotary sleeves 207 respectively sleeved outside each pull rod 201 are fixedly inserted into the driving plate 205. The rotary sleeve 207 can support the first driving pin 203. Each rotary sleeve 207 is respectively sleeved outside each first driving pin 203. A driving piston 208 is fixedly installed directly below the driving rod 206. The driving piston 208 can drive the driving rod 206 to move up and down. Three rotary seats 5 respectively sleeved at both ends of each second driving pin 204 are fixedly installed below the panel 1. The rotary seat 5 can fix the second driving pin 204 and prevent the second driving pin 204 from moving and rotating.

[0026] The panel 1 can fix the slewing base 5. At the same time, the panel 1 can limit the pull rod 201 in the horizontal direction, preventing the pull rod 201 from moving horizontally. When it is necessary to press and clamp the product for fixation, by starting the driving piston 208, the driving piston 208 pushes the driving rod 206 upward. The upward movement of the driving rod 206 can drive the slewing sleeve 207 to move upward. The upward movement of the slewing sleeve 207 can drive the driving plate 205 to move upward. The upward movement of the driving plate 205 can drive the slewing sleeve 207 to move upward. The upward movement of the slewing sleeve 207 can drive the first driving pin 203 to move upward. The upward movement of the first driving pin 203 can extrude the first spiral groove 3. The force on the first spiral groove 3 after being extruded by the first driving pin 203 can be divided into a horizontal component force and a vertically upward component force. Since the second driving pin 204 is fixed by the slewing base 5 and remains stationary, and the second driving pin 204 is located in the vertical structure inside the second spiral groove 4, the second driving pin 204 can limit the second spiral groove 4. At this time, the second driving pin 204 can prevent the second spiral groove 4 from rotating in the horizontal plane. After the second spiral groove 4 is limited, it can limit the pull rod 201. Therefore, the pull rod 201 can only move up and down and cannot rotate in the horizontal plane. The horizontal component force and the vertically upward component force received by the first spiral groove 3 can be transmitted to the pull rod 201. Therefore, after the pull rod 201 is limited, it can only rise. The rise of the pull rod 201 can drive the pressure plate 202 to rise.

[0027] The driving piston 208 continuously drives the driving rod 206 to rise. At this time, the second driving pin 204 moves to the horizontal structure below the second spiral groove 4. At this time, the second spiral groove 4 loses the horizontal limit. Therefore, the pull rod 201 loses the horizontal limit. However, the vertical movement of the second spiral groove 4 is limited by the second driving pin 204. Therefore, the second spiral groove 4 can only rotate in the horizontal plane sleeved outside the second driving pin 204. After the pull rod 201 is limited by the second spiral groove 4, it can only rotate around its own central axis in the horizontal plane. Therefore, the horizontal component force received by the first spiral groove 3 can drive the pull rod 201 to rotate around its own central axis in the horizontal plane. Relative torsion occurs between the first spiral groove 3 and the first driving pin 203. The pull rod 201 can drive the pressure plate 202 to rotate in the horizontal plane. The pressure plate 202 can clamp and fix the product placed on the support seat 7, effectively improving the safety of product processing. By driving the driving plate 205 to drive the pull rod 201 to move up and down, the second driving pin 204 and the second spiral groove 4 cooperate to eliminate the 90-degree rotation action. The slewing base 5 is connected to the panel 1. The second driving pin 204 and the second spiral groove 4 cooperate to control the rotation direction, so that the pull rod 201 rotates without rising action, thereby realizing a zero rotation angle.

[0028] As Figure 1 and Figures 3-4As shown, a guide rod 6 penetrates through one side of the driving piston 208. The guide rod 6 can limit the driving piston 208, enabling the driving piston 208 to only move up and down and not rotate in the horizontal plane, preventing the driving piston 208 from shifting.

[0029] As Figure 1 and Figure 5 shown, a support seat 7 is fixedly installed in the middle part above the panel 1. The support seat 7 can support the product. An angular pin 8 and a anti-misalignment key 9 are respectively installed above and on the side wall of the support seat 7. The angular pin 8 can limit between the product and the support seat 7, preventing the product from rotating on the support seat 7, and the anti-misalignment key 9 can improve the installation correctness of the support seat 7.

[0030] As Figure 1 and Figure 5 shown, a dust-proof cover plate 10 fixedly installed above the panel 1 is sleeved outside each pull rod 201. The dust-proof cover plate 10 can seal the connection part between the panel 1 and the pull rod 201, prevent dust from entering the connection part between the pull rod 201 and the panel 1, is beneficial to improving the smoothness of the lifting and rotation of the pull rod 201, and prevents the pull rod 201 from being severely worn.

[0031] As Figure 1 shown, a cover plate one 11 fixedly sleeved outside the driving rod 206 is fixedly installed in the middle part of the driving plate 205. The cover plate one 11 can limit the upper part of the driving plate 205 and the driving rod 206, and prevent the driving plate 205 and the driving rod 206 from separating.

[0032] As Figure 1 shown, a cover plate two 12 fixedly connected to the bottom surface of the guide rod 6 is installed below the driving piston 208. The cover plate two 12 can support and seal the bottom of the driving piston 208. At the same time, the cover plate two 12 can fix the bottom of the guide rod 6 and prevent the guide rod 6 from moving.

[0033] As Figure 1 and Figure 5 shown, a positioning body 13 sleeved outside the zero-rotation-angle clamping assembly 2 is fixedly installed below the panel 1. The positioning body 13 can protect each structure in the fixture.

[0034] As Figure 1 and Figure 5 shown, a transition plate 14 fixedly connected to the bottom surface of the cover plate two 12 is fixedly installed below the positioning body 13. The transition plate 14 can fix the bottom of the cover plate two 12.

[0035] As Figures 3-4As shown, a guiding slide rail 15 is provided below each pressing plate 202. The guiding slide rail 15 can limit each guiding steel ball 16. A plurality of guiding steel balls 16 arranged in sequence are installed in each guiding slide rail 15. The guiding steel balls 16 can reduce the contact area between the pressing plate 202 and the product.

[0036] When the pressing plate 202 presses the product, the pressing plate 202 drives the guiding steel balls 16 to move through the guiding slide rail 15. The guiding steel balls 16 can approach the product. When the guiding steel balls 16 contact the product, contact and extrusion occur between the guiding steel balls 16 and the product. After the guiding steel balls 16 are subjected to the frictional force in the horizontal direction, they can rotate. The rotation of the guiding steel balls 16 can fully reduce the resistance suffered by the pressing plate 202 during movement.
