Description

Technical Field

[0001] The utility model belongs to the field of mechanical processing, and in particular relates to a processing positioning and flipping device for mechanical accessories. Background Art

[0002] In modern mechanical processing production lines, in order to improve production efficiency and reduce manual workload, fully automated processing equipment is often used. Among them, the turning device is one of the more common production line equipment. It realizes automatic turning of the production line products through an automatic mechanism, making it convenient to process different sides of the production line products.

[0003] However, in actual use, it is found that most production line automatic turning devices can only turn over one product workpiece at a time. After the turning device completes a turning, it needs to return, which invisibly reduces the production rhythm, resulting in limited work efficiency of the production line and high production costs.

[0004] For example, the Chinese invention patent document with publication number CN115676315A discloses a product flipping device for an automatic production line, comprising a support plate, a mounting box is fixed to the middle section of the top wall of the support plate, a vertical first drive plate and a vertical second drive plate are slidably connected to the top walls of the support plate on both sides of the mounting box, the top of the first drive plate is rotatably connected to a horizontal first rotating shaft through a bearing, the top of the second drive plate is rotatably connected to a horizontal second rotating shaft through a bearing, a vertical push plate is fixed to the end of the first rotating shaft and the second rotating shaft close to each other, a clamping block is fixed to the side wall of the two push plates close to each other, a driven gear is fixed to the end of the second rotating shaft away from the first drive plate, and a motor is installed on the side wall of the second drive plate away from the first drive plate. The invention can realize automatic clamping and automatic flipping of the production line products, but it can be seen from its structure that the flipping mechanism can only clamp one product at a time, and after the flipping action is completed, it needs to be restored to the initial position before the next product can be clamped and flipped. Therefore, the technical solution of the invention still has the technical problem of low efficiency. Utility Model Content

[0009] A rotating motor, arranged at one end of the flip shaft, for driving the flip shaft to rotate;

[0010] The clamping mechanism is arranged on the bearing plane of the turning table and is used for positioning and clamping mechanical accessories.

[0011] Preferably, four turning tables are provided, and two adjacent turning tables form an angle of 90°.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] Combine the following Figure 1 to Figure 3 The utility model describes a processing positioning flipping device for mechanical parts.

[0028] refer to Figure 1 , Figure 1A schematic diagram of the structure of a machining positioning flipping device for mechanical parts provided by the utility model is shown. The flipping device 3 includes a first support body 304a and a second support body 304b arranged at intervals, and an axis-connected slider 306 arranged above the first support body 304a and the second support body 304b. A flip shaft 301 is rotatably connected between the two axis-connected sliders 306. One end of the flip shaft 301 is drivingly connected to a rotating motor 303, and the rotating motor is supported by a motor bracket 305 at the bottom. It can be understood that the height of the motor bracket 305 is adapted to the height of the flip shaft 301 so that the rotating motor 303 and the flip shaft 301 are coaxially connected. The flip shaft 301 is evenly distributed with a plurality of flip tables 302 along its circumference. In this embodiment, the number of the flip tables 302 is four, and the angle between two adjacent flip tables 302 is 90°. It can be understood that, according to the thickness of the mechanical parts, the angle between two adjacent turning tables 302 can be changed to increase the number. For example, six turning tables 302 can be evenly distributed along the axial direction of the turning axis 301, and the angle between each turning table 302 is 60°. Taking this embodiment as an example, four turning tables 302 are set. For the convenience of description, they are respectively called the first turning table 302a, the second turning table 302b, the third turning table 302c, and the fourth turning table 302d. Each turning table is provided with a clamping mechanism. Figure 2As shown, when in use, the flip device 3 is placed between two conveying platforms, that is, between the first conveying platform 1 and the second conveying platform 2. The two conveying platforms can be conveyed by rotating rollers, conveyor belts, or other conveying means of the prior art. In this embodiment, taking the conveyor crawler as an example, a first conveyor belt 101 is provided on the first conveying platform 1, and a second conveyor belt 201 is provided on the second conveying platform 2. Correspondingly, a clearance gap 30202 for accommodating the conveyor belt to enter is opened on the flip table 302. The output end of the first conveyor belt 101 cooperates with the first flip table 302a when it is horizontal. When the first flip table 302a is horizontal, the two have the same height, and the first conveyor 101 extends into the clearance gap 30202; the second conveying platform 2 is located on the other side of the flip device 3, and its height is lower than the first conveying platform 1, so as to receive the mechanical parts released from the third flip table 302c. When the flip shaft 301 rotates, the four flip tables 302 rotate in turn, receive the mechanical parts from the first conveyor belt 101, and complete the clamping and positioning. , continue to rotate, lift the mechanical parts from the first conveyor belt 101, and when it rotates to above the second conveyor belt 201 on the opposite side, complete a 180° flip. At this time, pause the rotation, release the clamping of the mechanical parts, and the mechanical parts are naturally placed on the second conveyor belt 201 and conveyed forward with the second conveyor belt 201, and then the flipping device 3 resumes the rotation operation; while pausing to release the mechanical parts, the clamping and fixing of the next mechanical parts can be completed above the first conveyor belt 101 on the other side, and the cycle is repeated, so that multiple mechanical parts can be flipped at the same time, which can basically meet the continuous production operation of the production line.

[0029] Specifically, the clamping mechanism includes a first cylinder 307, a first clamping portion 308, and a second clamping portion 309. The first cylinder 307 and the first clamping portion 308 are located at one end of the flip table 302. The first clamping portion 308 is connected to the output end of the first cylinder 307, and reciprocates along the axial direction of the flip shaft 301 with the expansion and contraction of the first cylinder 307. The second clamping portion 309 is located at the other end of the flip table 302, and is arranged away from the first clamping portion 308 along the axial direction of the flip shaft 301. The second clamping portion 309 can be fixed on the flip table 302. 02, as a reference, the first cylinder 307 pushes the first clamping part 308 to approach or move away from the second clamping part 309 to complete the clamping and release of the mechanical parts; the second clamping part 309 can also be connected to another second cylinder like the first clamping part 308. When two cylinders are set, the first clamping part 308 and the second clamping part 309 run synchronously in reverse. When the two move towards each other at the same time, the clamping action is completed. When the two move away from each other, the clamping is released. As it does not affect the understanding, the second cylinder is not shown in the figure.

[0030] Furthermore, at least one side of the flip table 302 is provided with a cylinder fixing plate 30201 extending outward, which is used to fix the first cylinder 307. Since the first cylinder 307 has a certain length and is set in the flip table 302, it needs to occupy a larger space. Therefore, the provision of the cylinder fixing plate 30201 can effectively improve the utilization rate of the flip table 302. It can be understood that when two cylinders are provided, cylinder fixing plates 30201 are provided on the edges of both sides of the flip table 302.

[0031] Furthermore, if Figure 3 As shown, in some other embodiments, a plurality of transmission roller groups are arranged above the flipping table 302, and each transmission roller group includes a plurality of transmission rollers 30203 arranged at intervals in the traveling direction of the pressing mechanical accessories. Correspondingly, a plurality of grooves for accommodating the transmission rollers 30203 are opened on the flipping table 302, and the transmission rollers 30203 are rotatably connected in the grooves, and the transmission surface is higher than the upper surface of the flipping table 302, so that the mechanical accessories can contact the transmission rollers 30203.

[0032] Furthermore, the rotating motor 303 may be a servo motor, a stepper motor or a steering gear. In the present embodiment, a servo motor is preferred.

[0033] It should be understood that the clamping mechanism in this embodiment can be other structures that can achieve positioning of the workpiece. In practical applications, it is necessary to set up different clamping mechanisms according to the shape and structure of the clamped mechanical parts. Therefore, the clamping mechanism of this embodiment is only used as a simple example and does not constitute an improper limitation of the present utility model.

[0034] The working principle of the embodiment of the utility model:

[0035] By using a rotating device and carrying a flip table that can be connected to a transmission mechanism, the mechanical parts are transmitted to the flip table, and the clamping mechanism provided on the flip table is used to stably clamp the mechanical parts. Driven by the rotating device, the flip table rotates around the flip axis, and the mechanical parts flip accordingly, and can complete a 180° flip. On the other side of the rotating device, another transmission mechanism connected to the rotating device is provided. After the mechanical parts are caught, the mechanical parts complete an automatic flip and continue to move to the next process with the transmission mechanism. Since the rotating device is provided with multiple flip tables, the flip tables can be circulated, which solves the technical problem in the prior art that the flip device needs to perform a reverse return action after completing a flip, improves the flipping efficiency, can achieve continuous operation, and significantly improves production efficiency.
