Description

Technical Field

[0001] This utility model belongs to the field of tooling technology, and in particular relates to a tooling for feeding circular pieces. Background Technology

[0002] When machining the outer diameter of small alloy discs on a grinding machine, multiple discs must first be placed on the worktable of the grinding machine for simultaneous machining. Because there is a grinding head above the grinding machine, the discs are held by hand and placed one by one on the worktable from the front side. During this process, because the discs are small, they are easy to slip when held by hand, and the continuous placement of discs makes the loading process time-consuming, labor-intensive, and inefficient. Utility Model Content

[0003] In view of the shortcomings and defects in the existing technology, the purpose of this utility model is to provide a feeding fixture for circular pieces, which solves the problem that the feeding fixture for small circular pieces on the grinding machine in the existing technology is time-consuming and labor-intensive in placing small circular pieces one by one on the grinding machine worktable.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a feeding fixture for small circular pieces, used to place small circular pieces onto a grinding machine worktable, including a tube capable of holding multiple small circular pieces, a push plate slidably disposed inside the tube, a push rod fixed to the rear side of the push plate, a handle fixed to the rear side of the push rod, an elongated opening on one side of the tube along its length, a sliding groove on the inner wall of the tube along its length, the push plate slidably connected to the sliding groove on the tube, a limiting block to prevent the push plate from sliding out of the tube is disposed behind the sliding groove, and a contact plate is disposed behind the push plate, the contact plate extending out of the tube when the slider hits the limiting block.

[0005] As a further improvement of this utility model, the contact plate is rotatably connected to the push plate.

[0006] As a further improvement of this utility model, a fixing plate is provided on the front side of the tube, the fixing plate is provided with a threaded hole, and a fastening bolt that can be screwed into the threaded hole is threadedly connected to the handle.

[0007] As a further improvement of this utility model, the tube is made of stainless steel.

[0008] Compared with the prior art, this utility model has the following advantages:

[0009] 1. By setting up a tube with a sliding push plate inside, and a handle connected to the back of the push plate via a push rod, when feeding small round pieces onto the grinding machine, the small round pieces are first placed into the tube, then the tube is placed on one side of the grinding machine's worktable. Then, the handle is gripped and the push plate is pushed forward, thereby pushing multiple small round pieces forward to the processing position on the worktable. The feeding process is very simple and convenient, saving time and effort, and greatly improving feeding efficiency.

[0010] Furthermore, by setting a limiting block on the rear side of the chute and a contact plate on the rear side of the push plate, the contact plate can protrude forward out of the tube after the push plate is pushed to its end, thus stably pushing all the small discs out of the tube. Moreover, after the small discs are pushed out, the push rod can be fixed directly from the outside to limit the small discs, eliminating the need to clamp the small discs after removing the tube. This is simple and convenient, avoiding the trouble of having to correct and clamp the small discs after removing the tube and causing them to fall over. After the small discs are processed, a small rod can be used from the other side to push the small discs back into the tube, saving time and effort.

[0011] In addition, a long opening is made on the tube, which not only makes it easy to observe the small disc inside the tube, but also makes it easy to apply grease or lubricant directly to the small disc through the long opening.

[0012] 2. By rotating the contact plate and the push plate together, when the contact plate is used to directly limit the small disc during processing, the friction between the small disc and the contact plate is reduced after the small disc rotates.

[0013] 3. By setting a fixing plate on the tube and a fastening bolt on the handle plate, after the small round piece is loaded, the tube can be directly fixed using a clamp or other fastener on the grinding machine. Then, the handle, i.e. the push rod, is fixed to the tube, so that the push plate can be fixed. After loading, this device can be used to directly limit the small round piece, which helps the subsequent processing of the small round piece. Attached Figure Description

[0018] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below. For clarity, only the structures relevant to the inventive features of the present invention are shown in the figures.

[0019] For ease of description, the coordinate system is defined as follows: Figure 1 As shown, the left and right directions are horizontal, the front and back directions are vertical, and the up and down directions are vertical.

[0020] This utility model discloses a feeding fixture for circular wafers. (Refer to...) Figure 1 and Figure 2 A feeding fixture for small circular pieces 11 is used to place small circular pieces 11 onto the worktable of a grinding machine. It includes a tube 1 capable of holding multiple small circular pieces 11. The tube 1 is made of stainless steel. A push plate 2 is slidably disposed inside the tube 1. A push rod 3 is fixed to the rear side of the push plate 2. A handle 4 is fixed to the rear side of the push rod 3. A long opening 5 is provided on one side of the tube 1 along its length. The long opening 5 not only facilitates observation of the small circular pieces 11 inside the tube 1, but also facilitates the direct application of grease or lubricating oil to the small circular pieces 11 through the long opening 5.

[0021] The inner wall of the tube 1 is provided with a sliding groove 6 along its length direction. The push plate 2 is slidably connected to the sliding groove 6 on the tube 1. A limiting block 7 is provided on the rear side of the sliding groove 6 to prevent the push plate 2 from sliding out of the tube 1. A contact plate 8 is provided on the rear side of the push plate 2. When the slider 12 hits the limiting block 7, the contact plate 8 extends out of the tube 1.

[0022] Furthermore, the contact plate 8 is rotatably connected to the push plate 2; therefore, during processing, if the contact plate 8 is used to directly limit the small disc 11, the friction between the small disc 11 and the contact plate 8 will be reduced after the small disc 11 rotates.

[0023] In addition, a fixing plate 9 is provided on the front side of the tube 1. The fixing plate 9 has a threaded hole, and a fastening bolt 10 that can be screwed into the threaded hole is threadedly connected to the handle 4. Therefore, after the small round piece 11 is loaded, the tube 1 can be directly fixed by the clamp or other fasteners on the grinding machine. Then, the handle 4, i.e. the push rod 3, is fixed to the tube 1, so that the push plate 2 can be fixed. After the loading is completed, this device can be used to directly limit the small round piece 11, which helps the subsequent processing of the small round piece 11.

[0024] This invention features a cylindrical tube 1 with a sliding push plate 2 inside. The push plate 2 is connected to a handle 4 via a push rod 3 on its rear side. Therefore, when feeding small round pieces 11 onto the grinding machine, each small round piece 11 is first placed into the cylindrical tube 1, then the cylindrical tube 1 is placed on one side of the grinding machine's worktable. Then, the handle 4 is gripped, and the push plate 2 is pushed forward, thereby pushing multiple small round pieces 11 forward to the processing position on the worktable. The feeding process is very simple and convenient, saving time and effort, and greatly improving feeding efficiency.

[0025] Furthermore, by setting a limiting block 7 on the rear side of the slide 6 and a contact plate 8 on the rear side of the push plate 2, after the push plate 2 is pushed to its end, the contact plate 8 can protrude forward from the tube 1, thereby stably pushing all the small discs 11 out of the tube 1. Moreover, after pushing out the small discs 11, the push rod 3 can be fixed directly from the outside to clamp and limit the small discs 11. There is no need to remove the tube 1 and then clamp the small discs 11 again, which is simple and convenient. It avoids the trouble of removing the tube 1, causing the small discs 11 to fall down, and then correcting and clamping the small discs 11 again. Moreover, after the small discs 11 are processed, a small rod can be used from the other side to directly push the small discs 11 back into the tube 1, saving time and effort.
