Example 1

Referring to fig. 1 and 2 together, the present embodiment provides a processing positioning mechanism 10 for clamping and fixing a product, and is particularly suitable for clamping and fixing a product with small volume and regular shape. The processing positioning mechanism 10 includes a jig main body 100 and a material ejection assembly 200, and the material ejection assembly 200 is disposed on the jig main body 100.

The jig main body 100 has at least one bin body 110 and a positioning member 120 penetrating into the inner wall side of the bin body 110.

When in use, the bin body 110 is used for containing a product, and the positioning piece 120 penetrating into the inner wall side surface of the bin body 110 is used for tightly supporting the product on the opposite inner wall side surface of the other bin body 110, and the product is fixed by using static friction force.

Accordingly, the ejector assembly 200 is compressibly disposed on the bottom surface of the inner wall of the bin body 110, and the ejector assembly 200 includes the ejector 210. By pressing, the ejector 210 is switched between the raised state and the depressed state.

When the processing and positioning mechanism 10 is used for clamping and positioning a product, the product is placed in the bin body 110. At this time, the product is pushed up by the pushing member 210 in the pushed-up state, and cannot completely enter the bin 110. The processing personnel presses the product, and then presses the ejector 210, so that the ejector 210 is switched to a sinking state. The product can completely enter the bin 110, and is positioned in a direction perpendicular to the bottom surface of the inner wall of the bin 110 by taking the ejector member 210 in a sinking state as a reference, and the direction is shown as an X direction in the figure. On the basis, the positioning piece 120 penetrates into the side surface of the inner wall of the bin body 110 to tightly support and fix the product. After the processing is completed, the processing personnel firstly releases the fixing of the positioning piece 120 to the product, then presses the product again, further presses down the ejection piece 210, and switches the ejection piece 210 to the ejection state, so that the product is ejected from the bin body 110, and the processing personnel can take the product. Compared with the existing mode of rotating the jig by 90 degrees or taking out the product through a third-party tool, the product is taken out after being automatically ejected by the ejection piece 210, so that the product is not easy to be damaged by three, the three-damage protection effect of the product processing is good, and the product taking and placing efficiency is higher.

In this embodiment, the jig main body 100 has five bin bodies 110, and the products are sequentially fixed in the five bin bodies 110 for processing. In this process, four sides and one end face of the product are sequentially exposed to the mouths of the five cartridge bodies 110. In addition, five products are simultaneously fixed on the jig main body 100, and the five products can be simultaneously processed.

In other embodiments of the present application, the number of cartridges 110 may be one, two, three, four, six or more.

Further, the connection part of the adjacent inner wall side surfaces of the bin body 110 is rounded, so that the processing difficulty of the bin body 110 is reduced, the product is prevented from being damaged in the process of taking and placing, and the three-damage rate of the product is improved.

In this embodiment, the positioning member 120 penetrates into the side surface of the inner wall of the bin body 110 along the Z direction, so that the product is positioned along the Z direction. In addition, the product is abutted against the side surface of the other inner wall of the bin body 110 along the Y direction, and positioning is completed along the Y direction.

In another embodiment of the present application, two positioning members 120 may be configured for each bin 110 to position the product along the Z-direction and the Y-direction, respectively.

Alternatively, the positioning member 120 is a screw, and the positioning member 120 is in threaded engagement with the jig main body 100.

Referring to fig. 3 and fig. 4 together, specifically, the ejector assembly 200 further includes an ejector seat 220, a first elastic member 230 and a pressing member 240.

Wherein, the top material seat 220 is disposed on the jig main body 100, and the top material seat 220 has a receiving groove 221 communicated with the bottom surface of the inner wall of the bin body 110. The receiving groove 221 is provided in the X direction with a bottom surface perpendicular to the X direction, and an inner wall of the receiving groove 221 is provided with a first wedge portion 222.

The first elastic member 230 is positioned in the receiving groove 221, is elastically deformed in the X direction, and is used to rebound the pushed-down ejector member 210. Each time the processor presses the ejector 210, two opposite moving processes are performed, and the two moving processes are respectively pressed and rebounded.

The pressing piece 240 is located at one end of the ejector piece 210 away from the bottom surface of the accommodating groove 221, and is provided with a second wedge portion 241, and at least part of the pressing piece 240 is slidably disposed in the accommodating groove 221. The worker presses the ejector 210 by the product acting on the pressing member 240.

Accordingly, the ejector 210 is movably disposed in the accommodating groove 221, and the ejector 210 abuts against the second wedge portion 241 when pressed down, and abuts against the first wedge portion 222 when rebounded.

In this process, the top material 210 and the first wedge-shaped portion 222 and the top material 210 and the second wedge-shaped portion 241 are all in inclined contact, so that the pressure direction between the top material 210 and the first wedge-shaped portion 222 and the pressure direction between the top material 210 and the second wedge-shaped portion 241 are obliquely intersected with the X direction. At this time, the pressure has a component force in a direction perpendicular to the X direction, so that the ejector 210 is driven to rotate around the X direction, and the rotation direction of the ejector 210 when abutting against the first wedge portion 222 is the same as the rotation direction when abutting against the second wedge portion 241.

In other words, each time the worker presses, the ejector 210 rotates twice in the same direction, and the sum of the two rotated angles is one cycle. The ejector 210 is switched from the raised state to the depressed state or from the depressed state to the raised state every time one cycle elapses.

In this embodiment, the inner wall of the accommodating groove 221 is provided with a first limiting portion 223 and a second limiting portion 224, and the distance between the first limiting portion 223 and the bottom surface of the accommodating groove 221 is greater than the distance between the second limiting portion 224 and the bottom surface of the accommodating groove 221. The first and second limiting portions 223 and 224 are alternately arranged along the circumferential direction of the receiving groove 221, and the first wedge portion 222 is located between adjacent first and second limiting portions 223 and 224.

Accordingly, the ejector 210 is provided with at least one extension 211. The extension 211 abuts against the first stopper 223 in the raised state and abuts against the second stopper 224 in the lowered state. The extension 211 abuts against the second wedge 241 when the ejector 210 is pushed down, and abuts against the first wedge 222 when the ejector 210 rebounds.

Referring to fig. 5 and fig. 6, taking the ejector 210 in the lifted state as an example, in the initial state, the extension portion 211 on the ejector 210 abuts against the first limiting portion 223.

The processor presses the pressing member 240 by the product, so that the second wedge portion 241 of the pressing member 240 abuts against the extension portion 211 of the ejector member 210, and the ejector member 210 rotates around the X direction, and the extension portion 211 rotates with the ejector member 210 to align with the first wedge portion 222. In this process, the first elastic member 230 is elastically deformed.

Then, the processing personnel loosens the product, the ejector 210 rebounds under the action of the elastic force of the first elastic member 230, and the extension 211 on the ejector 210 abuts against the first wedge-shaped portion 222 on the inner wall of the accommodating groove 221, so that the ejector 210 continues to rotate around the X direction, and the extension 211 rotates along with the ejector 210 until aligning with the second limiting portion 224 and abutting against the second limiting portion 224. Up to this point, the ejector 210 is switched from the raised state to the depressed state.

Similarly, the processor presses again, and the ejector 210 rotates in the X direction during the pressing, aligning the extension 211 with the next first wedge 222. After the worker releases, the ejector 210 continues to rotate around the X direction during the rebound process, so that the extension 211 is aligned with and abutted against the next first limiting portion 223. Up to this point, the ejector 210 is switched from the sinking state to the lifting state.

In some implementations of the present embodiment, the inner wall of the receiving groove 221 is provided with a first sliding groove 225 and a second sliding groove 226, respectively, in the X direction. The first sliding grooves 225 and the second sliding grooves 226 are alternately arranged along the circumferential direction of the receiving groove 221, and the depth of the second sliding grooves 226 is smaller than that of the first sliding grooves 225.

The depth of the first sliding groove 225 is greater, and the extension portion 211 can slide in the first sliding groove 225 until it abuts against an end of the first sliding groove 225 away from the bottom surface of the accommodating groove 221, so that the first limiting portion 223 is located at an end of the first sliding groove 225 away from the bottom surface of the accommodating groove 221.

In contrast, the depth of the second sliding groove 226 is smaller, and the extension portion 211 cannot enter the second sliding groove 226, so the second limiting portion 224 is located at one end of the second sliding groove 226 near the bottom surface of the accommodating groove 221.

In addition, a convex portion between the adjacent first slide groove 225 and second slide groove 226 serves as the first wedge portion 222, and one end of the first wedge portion 222 toward the bottom surface of the receiving groove 221 is provided as a slope.

It should be noted that, when the processing personnel presses the ejector member 210 in the lifted state, the ejector member 210 initially slides in the first slide groove 225, and is restricted by the first slide groove 225 and cannot rotate. After the ejector 210 slides out of the first chute 225, the ejector 210 starts to rotate around the X direction as the processor continues to press.

In this embodiment, the ejector 220 includes a first base 227 and a second base 228, and the first base 227 is detachably connected to the second base 228. The second seat 228 is hollow, and the second seat 228 and the first seat 227 surround to form the accommodating groove 221.

When assembling the ejector assembly 200, the pressing member 240, the ejector member 210 and the first elastic member 230 are first installed from the end of the second seat 228 near the first seat 227, so that the extension portion 211 abuts against the first limiting portion 223, and then the second seat 228 is connected with the first seat 227, so that the pressing member 240, the ejector member 210 and the first elastic member 230 are encapsulated.

Optionally, an external thread is disposed at an end of the first base 227 adjacent to the second base 228, and is in threaded engagement with the second base 228.

Optionally, the second seat 228 is provided with external threads and is in threaded engagement with the jig main body 100.

Further, the jig main body 100 is provided with the cavity 130, and the cavity 130 is located between two adjacent bin bodies 110, so that not only is the weight of the jig main body 100 reduced, but also the installation of the ejector assembly 200 is facilitated, namely the second seat 228 can be screwed in from the inner wall of the cavity 130 and is communicated to the bin bodies 110.

In the present embodiment, the first elastic member 230 adopts a compression spring, and the first elastic member 230 is disposed between the ejector member 210 and the bottom surface of the receiving groove 221.

Correspondingly, the first base 227 is provided with a cylinder 227a adapted to the inner diameter of the first elastic member 230. The first elastic member 230 is sleeved on the cylinder 227a, and the length of the first elastic member 230 in the natural state is greater than the length of the cylinder 227a.

In addition, one end of the ejector 210 facing the bottom surface of the receiving groove 221 is provided with a circular groove adapted to the first elastic member 230. The circular groove cooperates with the cylinder 227a to guide the first elastic member 230 to deform in the X direction, thereby preventing the first elastic member 230 from bending.

In this embodiment, the pressing member 240 is sleeved on the ejector member 210 and is in clearance fit with the ejector member 210.

Further, the pressing piece 240 is provided with a guiding portion 242, and the guiding portion 242 is slidably matched with the first sliding groove 225 and/or the second sliding groove 226. It should be noted that, when the guiding portion 242 is slidingly engaged with the first chute 225, the outer extending portion 211 of the ejector 210 abuts against the first limiting portion 223 through the pressing member 240 and the guiding portion 242.

During the pressing and rebounding of the ejector 210, the pressing member 240 slides in the X direction, and is guided and restrained by the guide portion 242. At the same time, since the pressing piece 240 does not rotate, damage to the surface of the product can be avoided.

Optionally, the outer side wall of the pressing member 240 is provided with a plurality of guiding portions 242, wherein one guiding portion 242 is slidably engaged with each first sliding groove 225, and the other guiding portion 242 is slidably engaged with the second sliding groove 226.

Further, in order to enable the processing positioning mechanism 10 to be conveniently and quickly transferred between different processing positions, so as to reduce the frequency of picking and placing products, the processing positioning mechanism 10 further includes an installation assembly 300 for realizing quick assembly and disassembly of the jig main body 100.

Referring to fig. 7 and 8 together, specifically, the mounting assembly 300 is composed of a mounting member 310, a limiting housing 320, a second elastic member 330 and a third elastic member 340.

Wherein the mount 310 includes a head 311 and a stem 312. In use, the mounting member 310 is fixed at each processing station, and then the fixture body 100 and the mounting member 310 are connected together by the limiting housing 320, the second elastic member 330 and the third elastic member 340.

It will be appreciated that a plurality of mounting members 310 may be provided for each mounting assembly 300, each mounting member 310 being secured to a different processing station and not being removable with the jig body 100.

For example, the mounting member 310 may be a bolt that is threadably secured to each processing station. At this time, configuring a plurality of mounts 310 per mount assembly 300 does not excessively increase the cost.

The limiting housing 320 is disposed on the jig main body 100, a first clamping groove 321 into which the head 311 is clamped is formed between the limiting housing 320 and the jig main body 100, and a second clamping groove 322 into which the rod 312 is clamped is disposed on the limiting housing 320.

Accordingly, the second elastic member 330 is located in the first slot 321. When the head 311 of the mounting member 310 is snapped into the first clipping groove 321, the second elastic member 330 is interference fit with the head 311, thereby forming a limit stop for the mounting member 310 in the X-direction and the Y-direction.

In addition, when the head 311 of the mounting member 310 is locked into the first locking groove 321, the third elastic member 340 abuts against a side of the head 311 facing away from the limiting housing 320, and cooperates with the limiting housing 320 to limit the mounting member 310 along the Z direction.

In this embodiment, the second elastic member 330 and the third elastic member 340 are made of elastic steel sheets.

The second elastic member 330 is bent to form a semi-open polygonal cavity, the opening of which is narrow, so that the resistance of the mounting member 310 when the head 311 passes through the opening is maximized.

One end of the third elastic member 340 is fixedly connected with the jig main body 100, and the other end extends into the first clamping groove 321 and inclines towards the limiting housing 320. When the head 311 of the mounting member 310 is completely engaged with the first engaging groove 321, the deformation of the third elastic member 340 is maximized, and the pressure applied to the head 311 is maximized, so that the head 311 of the mounting member 310 is fixed in cooperation with the second elastic member 330.

In short, the ejector 210 in the processing and positioning mechanism 10 can be switched between the raised state and the depressed state by pressing. When the liftout member 210 is switched from the liftout state to the sinking state, the product to be processed is positioned in the X direction with reference to the liftout member 210 and the pressing member 240. After the ejector 210 is switched from the sinking state to the lifting state, the ejector 210 and the pressing member 240 can automatically eject the processed product from the bin 110, so that the processing personnel can take the product. The taking mode is not easy to cause three injuries of the product, has good three injury protection effect in product processing, and has higher product taking and placing efficiency.

Example 2

Referring to fig. 9 and 10 together, the present embodiment provides a polishing apparatus, which includes a master tool 20 and the above-mentioned processing positioning mechanism 10. Wherein, the mounting member 310 is in threaded connection with the female jig 20, so that the jig main body 100 is detachably connected with the female jig 20.

When in use, the product is fixed on the jig main body 100, then the jig main body 100 is arranged on the master jig 20, and the product is ground by using a mechanical arm.
