Description

Technical Field

[0001] This utility model relates to a rotary fixture for automated mechanical processing. Background Technology

[0002] In modern manufacturing, automated machining technology has become a key means to improve production efficiency, ensure product quality, and reduce production costs. Rotary fixtures, as an important component of automated machining systems, are widely used in turning, milling, grinding, drilling, and other machining processes. The main function of rotary fixtures is to hold the workpiece and achieve precise rotational positioning during machining to meet the multi-faceted machining requirements of complex workpieces.

[0003] A search revealed Chinese Patent Publication No. CN 221364208 U, which discloses a rotary fixture for automated machining. The fixture includes an operating table with a grinding assembly on one side of its upper end. A first servo motor is fixedly connected to the center of the lower end of the operating table. The first servo motor is fixedly connected to a rotating disk via a shaft. A rotating platform is rotatably connected to the upper end of the rotating disk. There are three sets of rotating platforms. A second servo motor is fixedly connected to the lower shaft of each rotating platform. A clamping device is provided on the surface of the rotating platform. The clamping device includes a telescopic cylinder, a connecting block, a clamping head, and a synchronous servo motor. This design, through the telescopic cylinder, can fix the workpiece blank during telescopic movement. After fixing, the clamping heads on both sides rotate synchronously, causing the workpiece blank to rotate and be ground, achieving the purpose of rotating and grinding while fixed.

[0004] Regarding the aforementioned related technologies, the inventors have discovered the following drawbacks: When existing rotary clamps clamp workpiece blanks, they typically clamp and fix the outer surface of the workpiece blank. This clamping method affects the complete machining of the outer surface of the workpiece blank, requiring continuous adjustment of the clamping position on the outer surface of the workpiece blank according to the machining position of the outer surface during machining, thus affecting the efficiency of machining the workpiece blank. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a rotary fixture for automated mechanical processing, which is not only reasonably structured, but also convenient and fast.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a mechanical automated machining rotary fixture, including a connecting shaft rotatably connected to the top of a support column, a first motor fixedly mounted at one end of the connecting shaft, a threaded rod linked to the output end of the first motor via a first belt, the threaded rod being rotatably connected to the outside of the connecting shaft and threadedly connected to a connecting ring sleeved on the outside of the connecting shaft to drive its axial translation, a plurality of long rods evenly distributed around one end of the connecting ring, each long rod having a push rod fixedly mounted at its end, each push rod penetrating vertically through a swing rod and slidably connected to a clearance sliding hole opened on the swing rod, the upper and lower ends of the push rod being respectively hinged to the connecting shaft and a clamping plate, the clamping plate extending along the length direction of the connecting shaft and connected to the connecting shaft via a limiting rod at the extended end, the two ends of the limiting rod being respectively hinged to the connecting shaft and the clamping plate.

[0007] Furthermore, the threaded rod is provided in two sets, and the two threaded rods are connected to the first motor drive shaft via two sets of first belts, with the two first belts spaced apart on the first motor drive shaft.

[0008] Furthermore, the threaded rod consists of a threaded section and a smooth section, and the two threaded rods are rotatably connected to a fixed plate fixed on both sides of the connecting shaft via the smooth section.

[0009] Furthermore, each of the inner rings of the connecting ring has two protruding push plates, and each push plate has a threaded hole for threaded connection with the threaded rod.

[0010] Furthermore, each of the long rods is arranged in pairs, with the two long rods in each pair arranged in parallel and their ends fixed to the two ends of the push rod. The push rod is cylindrical, and the sliding hole is strip-shaped.

[0011] Furthermore, the swing rod and the limiting rod connected to the same clamping plate are arranged in parallel, and the upper and lower ends of the swing rod and the limiting rod are respectively hinged to the clamping rod and the connecting shaft via U-shaped hinge seats.

[0012] Furthermore, the connecting ring has a convex-shaped slider protruding from it, and each connecting shaft is fixed with a slide block. The slide block has a horizontal groove that runs through it along the length of the connecting shaft to allow the slider to slide. The slide block and the fixed plate are offset from each other.

[0013] Furthermore, the cross-section of the connecting shaft is a regular octagon, and the swing rod, clamping rod and clamping plate are each provided in eight sets and are respectively arranged on eight surfaces on the outer periphery of the connecting shaft. The outer surface of the clamping rod is an arc surface to abut against the part blank.

[0014] Furthermore, the connecting shaft has a horizontally extending connecting rod at its end, which is fixedly connected to the connecting plate via the connecting rod. A rotating shaft is coaxially fixed to the other side of the connecting plate. The rotating shaft is rotatably connected to the support column and extends out of the support column and is driven to rotate by the second motor via the second belt.

[0015] Furthermore, the bottom end of the support column is fixedly connected to a base, and the second motor is fixedly connected to the base.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model, by setting up components such as a swing rod, a limiting rod, and a clamping plate, uses the swing of the swing rod in conjunction with the swing of the limiting rod to push the clamping plate gradually away from the connecting shaft, causing the clamping plate to move towards the inner wall of the workpiece blank. This allows the clamping plate to clamp the workpiece blank through the inner wall of the workpiece blank, thus achieving the effect of clamping and fixing the workpiece blank through the inner wall of the workpiece blank, preventing the fixture from affecting the complete processing of the outer surface of the workpiece blank, and improving the efficiency of processing the outer surface of the workpiece blank.

[0017] 2. This utility model uses a swing rod and a limiting rod arranged in parallel to each other. The swing rod and the limiting rod swing at the same angle, so that the swing rod and the limiting rod can drive the clamping plate to move towards the inner wall of the workpiece blank while maintaining a horizontal state. This allows the clamping plate to stably fit against the inner wall of the workpiece blank, ensuring the stability of the clamping plate in clamping and fixing the workpiece blank through the inner wall of the workpiece blank.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Attached Figure Description

A first motor 8 is fixed at the center of one end of the connecting shaft. A threaded rod 10 is linked to the output end of the first motor via a first belt 9. The threaded rod is rotatably connected to the outside of the connecting shaft and threadedly connected to a connecting ring sleeved on the outside of the connecting shaft to drive its axial translation. The connecting ring is coaxially sleeved on the outside of the connecting shaft but not connected to the connecting shaft. Several sets of long rods 19 are evenly distributed around the circumference of the connecting ring away from one end. Each long rod has a push rod 13 fixed at its end. Each push rod vertically passes through a swing rod 5 and is slidably connected to a clearance sliding hole 20 opened on the swing rod. The upper and lower ends of the push rod are respectively hinged to the connecting shaft and the clamping plate 6. The clamping plate extends along the length of the connecting shaft and is connected to the connecting shaft via a limiting rod 7 at its extended end. The two ends of the limiting rod are respectively hinged to the connecting shaft and the clamping plate.

[0023] In this embodiment of the utility model, two sets of threaded rods are provided, and the two threaded rods are connected to the first motor drive shaft via two sets of first belts, with the two first belts spaced apart on the first motor drive shaft.

[0024] In this embodiment of the utility model, the threaded rod is composed of a threaded section and a smooth section, and the two threaded rods are rotatably connected to the fixed plate 21 fixed on both sides of the connecting shaft via the smooth section.

[0025] In this embodiment of the utility model, two push plates 11 protrude from the inner ring of the connecting ring, and each push plate is provided with a threaded hole 22 for threaded connection with the threaded rod.

[0026] In this embodiment of the utility model, the long rods are arranged in pairs, and the two long rods in each pair are arranged in parallel and their ends are respectively fixed to the two ends of the push rod. The push rod is cylindrical and the sliding hole is strip-shaped.

[0027] In this embodiment of the utility model, the swing rod and the limiting rod connected to the same clamping plate are arranged in parallel, and the upper and lower ends of the swing rod and the limiting rod are respectively hinged to the clamping rod and the connecting shaft via the U-shaped hinge seat 23.

[0028] In this embodiment of the utility model, a slider 14 in the shape of a convex character protrudes from the connecting ring, and a slide seat 24 is fixedly provided on the connecting shaft. A sliding groove 15 for sliding of the slider is horizontally opened through the slide seat along the length direction of the connecting shaft. The slide seat and the fixing plate are offset from each other.

[0029] In this embodiment of the utility model, the cross-section of the connecting shaft is a regular octagon, and the swing rod, clamping rod and clamping plate are all arranged in eight sets and respectively arranged on the eight surfaces of the outer periphery of the connecting shaft. The outer surface of the clamping rod is an arc surface to abut against the workpiece blank.

[0030] In this embodiment of the utility model, the connecting shaft has a horizontally extending connecting rod 25 at its end, which is fixedly connected to the connecting plate via the connecting rod. The other side of the connecting plate 3 is coaxially fixedly connected to a rotating shaft 2.

[0031] In this embodiment of the utility model, the bottom end of the support column is fixedly connected to a base 1, and the second motor is fixedly connected to the base.

[0032] The working principle of this utility model embodiment is as follows: The blank of the part to be processed is placed on the outer surface of the clamping plate 6. The first motor 8 works, causing the first belt 9 to drive the threaded rod 10 to rotate. The rotation of the threaded rod 10 causes the push plate 11 to drive the connecting ring 12 to move closer to the clamping plate 6. When the connecting ring 12 moves, it will drive the push rod 13 to move towards the limiting rod 7, so that the outer surface of the middle part of the push rod 13 slides in the sliding hole in the middle part of the swing rod 5, causing the swing rod 5 to swing. The swing rod 5, together with the limiting rod 7, drives the clamping plate 6 to gradually move away from the connecting shaft 4, so that the outer surface of the clamping plate 6 away from the connecting shaft 4 is tightly attached to the inner wall of the blank, and the inner wall of the blank is fixed by the top. When it is necessary to rotate the blank, the second motor 16 works, causing the second belt 17 to drive the rotating shaft 2 to rotate. The rotating shaft 2 drives the connecting shaft 4 to rotate through the connecting plate 3. When the connecting shaft 4 rotates, it will drive the blank to rotate through the clamping plate 6.

Anyone can derive other forms of rotary jigs for automated mechanical processing based on the teachings of this utility model. All equivalent variations and modifications made within the scope of the claims of this utility model should be considered within the scope of this utility model.
