Description

Technical Field

[0001] This utility model relates to a device for positioning grinding barrels, and more specifically to a device for positioning grinding barrels, specifically for internal positioning of large-size grinding barrels. Background Technology

[0002] A vibratory grinder, also known as a grinding machine, reduces burrs and rough edges on the workpiece surface through friction between the workpiece and abrasive materials such as stones. It is typically designed as a drum-type grinder. Suitable for surface polishing, chamfering, deburring, grinding, and gloss finishing of small to medium-sized workpieces, it does not damage the original shape and dimensional accuracy of the parts, can eliminate internal stress, and improves the surface finish and precision. For example, the most common applications are the preliminary surface treatment of products such as Buddhist beads, small die-cast parts, and screws, all of which require the use of this type of vibratory grinder.

[0003] When performing grinding operations in a grinding machine, a grinding barrel is required. The grinding barrel stores the workpiece and abrasive materials such as stones, and also allows the workpiece to come into contact with the abrasive materials during rotation, thereby achieving the grinding process.

[0004] Furthermore, when the grinding barrel is being used and processed, if it is necessary to polish or remove rust from the weld seams of the grinding barrel, or to perform other processing operations such as welding, the grinding barrel needs to be fixedly installed to maintain its stability and facilitate the processing operations. Utility Model Content

[0005] One objective of this invention is to provide a new technical solution for a positioning device for grinding large-size grinding barrels.

[0006] According to a first aspect of the present invention, a positioning device for grinding large-size grinding barrels is provided, including a positioning frame, an installation mechanism fixedly installed on the lower part of the positioning frame, and an expansion clamping mechanism movably installed on the installation mechanism.

[0007] The expansion clamping mechanism includes an adjusting screw, on which a push threaded ring is threadedly connected. An expansion push plate is fixedly installed at the other end of the mounting mechanism. A support plate is movably connected to the push threaded ring, and the other end of the support plate is movably connected to one end of the expansion push plate.

[0008] Furthermore, one end of the expansion push plate is provided with an elastic plate, the end of the elastic plate is fixedly provided with an insertion plate, and the inner side of the other end of the expansion push plate is fixedly provided with a first connector.

[0009] Furthermore, the installation mechanism includes a penetration rod fixedly connected to the lower part of the positioning frame, one end of the penetration rod having an insertion groove circumferentially formed, and the insertion plate engaging with the inside of the insertion groove.

[0010] Furthermore, a mounting groove is provided at the center of the other end of the probing rod, and a sliding groove is provided axially on the outer side of the mounting groove. The adjusting screw is installed inside the mounting groove, and the pushing threaded ring is also movably located inside the mounting groove.

[0011] Furthermore, the push threaded ring is circumferentially fixed with a plurality of second connectors, one end of the support plate is movably connected to the second connectors via a pin, and the other end of the support plate is movably connected to the first connector via a pin.

[0012] Furthermore, a limiting ring is welded onto the probing rod, and a plurality of pushing springs are circumferentially installed on one side of the limiting ring, with the other end of the pushing springs fixedly connected to one side of the elastic plate.

[0013] Furthermore, one end of the adjusting screw passes through the positioning frame, and a transmission gear is keyed to the end of the adjusting screw.

[0014] According to one embodiment of this disclosure, the present invention can penetrate deep into the interior of the grinding barrel through an installation mechanism, and can also install an expansion clamping mechanism through the installation mechanism, so that the expansion clamping mechanism can be retracted and adjusted, and the grinding barrel can be stably clamped and fixed.

[0015] In use, the threaded ring is moved and adjusted on the indentation rod by rotating the adjusting screw. When the threaded ring is adjusted, one end of the support plate is pushed, which causes the expansion push plate connected to the other end of the support plate to open. This allows the expansion push plate to open and contact the inner wall of the grinding barrel, making it easier to clamp and fix the grinding barrel stably.

[0016] Furthermore, in order to push the expansion push plate and maintain its support strength, a limiting ring and a pushing spring are used to push the elastic plate, thereby enabling the elastic plate to maintain stable strength and preventing the expansion push plate from becoming unstable, which would make it difficult to stably clamp and fix the grinding barrel.

[0031] It should be noted that the elastic plate 304 is designed to push one end of the expansion push plate 303 so that the expansion push plate 303 can fit against the inner wall of the grinding barrel, and the insertion plate 305 and the first connector 312 are designed to install and connect the expansion push plate 303.

[0032] In this embodiment, preferably, the installation mechanism 2 includes a penetration rod 201 fixedly connected to the lower part of the positioning frame 1. One end of the penetration rod 201 is provided with an insertion groove 202 in the circumferential direction, and the insertion plate 305 is engaged and connected to the inside of the insertion groove 202.

[0033] It should be noted that the setting of the insertion rod 201 facilitates the insertion of the expansion clamping mechanism 3 into the interior of the grinding barrel, and the setting of the insertion slot 202 is used to fix and connect one end of the expansion push plate 303, and the expansion push plate 303 is fixedly installed through the insertion plate 305 and the insertion slot 202.

[0034] In this embodiment, preferably, a mounting groove 203 is provided at the center of the other end of the deep rod 201, and a sliding groove 204 is provided axially on the outer side of the mounting groove 203. The adjusting screw 301 is installed inside the mounting groove 203, and the threaded ring 308 is also moved inside the mounting groove 203.

[0035] It should be noted that the mounting groove 203 is designed to install the adjusting screw 301, and the push threaded ring 308 is also located inside the mounting groove 203, so that the adjusting screw 301 can drive the push threaded ring 308 to perform thread adjustment.

[0036] In this embodiment, preferably, a plurality of second connectors 309 are fixedly provided circumferentially on the push threaded ring 308, one end of the support plate 311 is movably connected to the second connectors 309 through a pin 310, and the other end of the support plate 311 is movably connected to the first connector 312 through a pin 310.

[0037] It should be noted that the support plate 311 is connected by pushing the second connector 309 on the threaded ring 308, so that when the threaded ring 308 moves, one end of the expansion push plate 303 can be pushed through the support plate 311.

[0038] In this embodiment, preferably, a limiting ring 307 is welded onto the indentation rod 201, and a plurality of push springs 306 are circumferentially installed on one side of the limiting ring 307, and the other end of the push springs 306 is fixedly connected to one side of the elastic plate 304.

[0039] It should be noted that the limiting ring 307 is set to fix the push spring 306, so that the push spring 306 can push the elastic plate 304, which helps to maintain the stability of the elastic plate 304, and allows the expansion push plate 303 to push and clamp the inner wall of the grinding barrel.

[0040] In this embodiment, preferably, one end of the adjusting screw 301 passes through the positioning frame 1, and the end of the adjusting screw 301 is keyed to a transmission gear 302;

[0041] It should be noted that the equipment is installed through the positioning frame 1, and the setting of the transmission gear 302 at the end of the adjusting screw 301 is used to enable the external servo motor to output power. The transmission gear 302 drives the adjusting screw 301 to rotate, which facilitates the control of the expansion push plate 303 to open.

[0042] The specific operational procedures for this application are as follows:

[0043] In use, the mounting mechanism 2 and the expansion clamping mechanism 3 are installed through the positioning frame 1, and a servo motor is installed on the upper end of the positioning frame 1. The servo motor drives the transmission gear 302 in the expansion clamping mechanism 3, so that the adjusting screw 301 rotates inside the mounting groove 203 of the rod 201, thereby allowing the push threaded ring 308 to move and adjust inside the mounting groove 203. This makes it easy for the push threaded ring 308 to connect to the support plate 311 through the second connector 309, so that the support plate 311 can open when the push threaded ring 308 moves, making it easy to open one end of the expansion push plate 303, so that the expansion push plate 303 can fit against the inner wall of the grinding barrel, thereby achieving positioning and clamping of the grinding barrel.

[0044] An elastic plate 304 is provided at the other end of the expansion push plate 303. The elastic plate 304 can be bent and contracted when the expansion push plate 303 is closed, and straightened when the expansion push plate 303 is opened, thus supporting the expansion push plate 303. The push spring 306 is fixedly installed through the limiting ring 307, and the other end of the push spring 306 is fixed to one side of the elastic plate 304 to push the elastic plate 304, maintain the support stability of the elastic plate 304, and prevent the expansion push plate 303 from being unstable, which would make it inconvenient to clamp and fix the grinding barrel stably. The expansion push plate 303 mainly positions and fixes the inner wall of the grinding barrel through the connection between the support plate 311 and the expansion push plate 303, which facilitates the grinding barrel grinding process.
