Description

Technical Field

[0001] This utility model relates to the field of flipping fixtures, specifically a workpiece flipping device. Background Technology

[0002] In modern industrial production, efficient workpiece processing is key to improving production efficiency and product quality. Many workpieces need to be flipped during processing in order to process their different surfaces.

[0003] Existing workpiece flipping devices use a flipping frame as a carrier, and a gantry crane drives the flipping frame to flip the workpiece. Before flipping, the workpiece is fixed by a fixing device to prevent it from falling off during the flipping process and causing loss.

[0004] Most existing fixing devices clamp the workpiece using clamping components such as chucks. However, the clamping teeth used to fix the workpiece are prone to wear. The existing clamping teeth are integrally molded structures, and when the clamping teeth wear out, the entire clamping tooth often needs to be replaced, resulting in great waste and increasing production costs.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1 to 8 This utility model provides a technical solution: a workpiece flipping device;

[0029] Example 1: In order to replace the first jaw 404 or the second jaw 405 that cannot clamp the workpiece due to wear, slots 401 are provided on both sides of the sleeve 4. Guide blocks 403 are fixedly installed on the bottom side wall of the sleeve 4. Countersunk holes 409 are provided on the upper surface of the sleeve 4. Insert plates 406 are fixedly installed on the side walls of the first jaw 404 and the second jaw 405. Threaded holes 407 are provided on the upper end face of the insert plate 406. Bolts 410 are provided on the inner surface of the countersunk holes 409. Bolts 410 are threadedly connected to the threaded holes 407. The first jaw 404 and the second jaw 405 are inserted into the inner surface of the slots 401 through the insert plates 406.

[0030] When the first jaw 404 or the second jaw 405 is unable to clamp the workpiece due to wear, the bolt 410 in the countersunk hole 409 can be loosened from the threaded hole 407, and the first jaw 404 or the second jaw 405 can be pulled out from the slot 401 on the side end face of the ferrule 4 through the insert plate 406. Thus, only the worn jaw head needs to be replaced, and the entire ferrule 301 does not need to be replaced, which can reduce unnecessary waste and lower production costs.

[0031] A dovetail protrusion 303 is fixedly installed on the upper surface of the card holder 301. Guide grooves 302 are provided on both sides of the card holder 301. A dovetail groove 402 is provided on the inner surface of the card sleeve 4. The dovetail groove 402 is slidably connected to the dovetail protrusion 303. The lower surface of the card holder 301 is fixedly connected to the slider 203. The guide block 403 is slidably connected to the guide groove 302. The card sleeve 4 is slidably sleeved with the card holder 301.

[0032] When the ferrule 4 needs to be replaced, it can be removed by loosening the bolt 410 in the countersunk hole 409 through the sliding fit between the dovetail protrusion 303 and the dovetail groove 402. This eliminates the need for a complicated disassembly and reassembly process, reducing maintenance time and labor intensity.

[0033] Example 2: Based on Example 1, in order to drive the clamping assembly, a clamping drive assembly 2 for fixing the workpiece is fixedly installed on the surface of the flip frame 1. The clamping drive assembly 2 includes: a mounting plate 201, a sliding groove 202 is formed on the surface of the mounting plate 201, a slider 203 is slidably connected to the inner surface of the sliding groove 202, a hydraulic cylinder 204 is fixedly installed on the lower surface of the mounting plate 201, and a connecting plate 205 is fixedly connected to the output end of the hydraulic cylinder 204. The side walls of the connecting plate 205 are all... A number of first lugs 206 are fixedly installed at equal intervals. The side wall of the first lug 206 is provided with a first mounting groove 207. The side wall of the card holder 301 is fixedly installed with a second lug 304. The side wall of the second lug 304 is provided with a second mounting groove 305. A connector 208 is rotatably installed on the inner wall of the first mounting groove 207. A pin 209 that passes through the connector 208 is inserted into the outer wall of the first lug 206. The first lug 206 and the second lug 304 are connected by the connector 208.

[0034] The hydraulic cylinder 204 drives the connecting plate 205 to move up and down, which can drive the connecting piece 208 in the first lug 206 and the second lug 304 to rotate. When the connecting piece 208 rotates, the first claw 404 or the second claw 405 on the ferrule 4 moves closer to the workpiece that needs to be clamped through the sliding cooperation between the ferrule 301 and the slider 203, thereby fixing it and preventing the workpiece from falling off and causing loss when the workpiece is flipped by the overhead crane driving the flipping frame.

[0035] Working Principle: In actual use, the workpiece to be flipped is first placed on the surface of the flipping frame 1. If the workpiece is a hollow cylinder, the connecting plate 205 can be driven up and down by the hydraulic cylinder 204, which can drive the connecting piece 208 in the first lug 206 and the second lug 304 to rotate. When the connecting piece 208 rotates, the first jaw 404 on the sleeve 4 expands through the sliding engagement of the seat 301 and the slider 203, and then moves closer to the inner wall of the hollow cylinder to fix it. If the workpiece is irregular, it can be placed on the surface of the mounting plate 201, and then the second jaw 405 on the sleeve 4 can be driven by the hydraulic cylinder to move closer to the workpiece to be clamped through the sliding engagement of the seat 301 and the slider 203 to fix it. The anti-slip texture 408 on the side wall of the first jaw 404 or the second jaw 405 increases the size of the first jaw 404 when it comes into contact with the workpiece. The friction between the first or second jaw 404 and the workpiece increases the clamping force to a certain extent. After being fixed, the workpiece can be flipped by the gantry crane driving the flipping frame. When the first jaw 404 or the second jaw 405 can no longer clamp the workpiece due to wear, the first jaw 404 or the second jaw 405 can be pulled out from the slot 401 on the side end face of the sleeve 4 by loosening the bolt 410 in the countersunk hole 409 and the threaded hole 407. Then, only the worn jaw head needs to be replaced, and the entire sleeve 301 does not need to be replaced, which can reduce unnecessary waste and reduce production costs. When the sleeve 4 needs to be replaced, the sleeve 4 can be removed by loosening the bolt 410 in the countersunk hole 409 through the sliding fit between the dovetail protrusion 303 and the dovetail groove 402. There is no need for a complicated disassembly and reassembly process, which reduces maintenance time and labor intensity.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
