Description

Technical Field

[0001] This utility model relates to the field of double-end face grinding machine technology, and more specifically to a workpiece positioning mechanism for a double-end face grinding machine. Background Technology

[0002] A double-end face grinder is a high-efficiency surface processing machine tool that grinds two parallel end faces simultaneously in one processing cycle. Based on its structure, it can be divided into horizontal and vertical types. Based on the feeding method, it can be divided into through-type, rotary type, and reciprocating type. When using a double-end face grinder to process a workpiece, a positioning mechanism can be used to position the workpiece, making the workpiece more convenient during the processing.

[0003] For example, application number "CN202323502832.7" discloses a workpiece positioning mechanism for a double-end face grinder, including a side plate. A slide rail is formed on the side of the side plate, and a pressing plate is provided on the side of the side plate. A slider is welded to the side of the pressing plate and is located inside the slide rail. A fixing plate is fixedly connected to the other end of the slider. An internal threaded seat is welded to the side of the fixing plate, and an external threaded rod is installed inside the internal threaded seat. This double-end face grinder workpiece positioning mechanism, by forming a slide rail on the side of the side plate, allows the side of the limiting block to fit against the side of the side plate. The pressing plates are symmetrically distributed, allowing the pressing plates to move based on the slide rail. When positioning workpieces of different sizes is required, the pressing plates can be moved to the appropriate position via the slide rail and slider. Subsequently, a rotating turntable drives the external threaded rod, causing the external threaded rod to press against the side plate to achieve a fixing effect. This improves the compatibility of the double-end face grinder workpiece positioning mechanism during use.

[0004] After improvements to the workpiece positioning mechanism of this double-end face grinder, it can clamp and fix workpieces of different sizes. However, when fixing the workpiece, the device uses two flat extrusion plates to move and clamp the workpiece. This method can only fix workpieces with relatively flat sides. However, most workpieces currently have irregular shapes on both sides. When clamping and fixing workpieces with irregular shapes on both sides, the contact surface is small and the clamping and fixing is not stable enough, which needs to be improved. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a workpiece positioning mechanism for a double-end face grinder to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a workpiece positioning mechanism for a double-end face grinder, including an L-shaped mounting bracket. A push plate is provided on the right side of the L-shaped mounting bracket, and a limiting mechanism is provided on the right side of the push plate. The limiting mechanism includes a liquid storage tank, a piston cylinder, and a positioning clamping plate. There are two liquid storage tanks, which are symmetrically and fixedly installed on the right side of the push plate. There are multiple piston cylinders and multiple fixing frames. One end of each of the multiple piston cylinders is fixedly connected to one side of the two liquid storage tanks. The other end of each of the multiple piston cylinders is movably sleeved with a piston rod. One end of each piston rod is fixedly connected to a fixing frame. A connecting shaft is fixedly installed inside the fixing frame. A connecting block is rotatably sleeved on the outer wall of the connecting shaft through a bearing. The middle part of one side of the positioning clamping plate is fixedly connected to one side of the connecting block.

[0007] Furthermore, a hydraulic rod is fixedly connected to the middle of the other side of the liquid storage tank. The telescopic end of the hydraulic rod extends into the interior of the liquid storage tank and is fixedly connected to a piston plate. The outer wall of the piston plate is movably sleeved inside the liquid storage tank, and the interior of the liquid storage tank is filled with hydraulic oil.

[0008] Furthermore, a plurality of conduits are fixedly sleeved on one side of the liquid storage tank, and one end of the plurality of conduits is fixedly sleeved inside one end of a plurality of piston cylinders.

[0009] Furthermore, a piston head is movably sleeved inside the piston cylinder, and one end of the piston head is fixedly connected to the other end of the piston rod.

[0010] Furthermore, a return spring is provided inside the piston cylinder, one end of which is fixedly connected to one side of the piston head, and the other end of the piston rod is fixedly connected to the other end of the inner wall of the piston cylinder.

[0011] Furthermore, a second hydraulic rod is fixedly installed in the middle of the left side of the L-shaped mounting bracket. The telescopic end of the second hydraulic rod extends to the right side of the L-shaped mounting bracket and is fixedly connected to the middle of the left side of the push plate.

[0012] Furthermore, the bottom of the L-shaped mounting bracket has four mounting holes, which are distributed at the four corners of the bottom of the L-shaped mounting bracket.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The workpiece positioning mechanism for a double-end grinding machine involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1:

[0023] like Figure 1-4As shown, a workpiece positioning mechanism for a double-end face grinder includes an L-shaped mounting bracket 1. A push plate 2 is located on the right side of the L-shaped mounting bracket 1, and a limiting mechanism 3 is located on the right side of the push plate 2. The limiting mechanism 3 includes a liquid storage tank 31, piston cylinders 34, and a positioning clamping plate 38. There are two liquid storage tanks 31, symmetrically fixedly mounted on the right side of the push plate 2. There are multiple piston cylinders 34 and multiple fixing frames 35. One end of each piston cylinder 34 is fixedly connected to one side of the two liquid storage tanks 31, and the other end of each piston cylinder 34 is movably sleeved with a piston rod 342. One end of each piston rod 342 is fixedly connected to a fixing frame 35. A connecting shaft 36 is fixedly mounted inside the fixing frame 35. A connecting block 37 is rotatably sleeved on the outer wall of the connecting shaft 36 via a bearing. The middle of one side of the positioning clamping plate 38 is fixedly connected to one side of the connecting block 37. The liquid storage tank 31... 1. A hydraulic rod 311 is fixedly connected to the middle of the other side. The telescopic end of the hydraulic rod 311 extends into the interior of the reservoir 31 and is fixedly connected to a piston plate 32. The outer wall of the piston plate 32 is movably sleeved inside the reservoir 31. The outer wall of the piston plate 32 is adapted to the inner wall of the reservoir 31. Hydraulic oil is provided inside the reservoir 31. Multiple conduits 33 are fixedly sleeved on one side of the reservoir 31. One end of the multiple conduits 33 is fixedly sleeved inside one end of multiple piston cylinders 34. A piston head 341 is movably sleeved inside the piston cylinder 34. One end of the piston head 341 is fixedly connected to the other end of the piston rod 342. A return spring 343 is provided inside the piston cylinder 34. One end of the return spring 343 is fixedly connected to one side of the piston head 341. The other end of the piston rod 342 is fixedly connected to the other end of the inner wall of the piston cylinder 34.

[0024] In this embodiment, the hydraulic oil inside the reservoir 311 is squeezed into the piston cylinders 34 by the cooperation of the first hydraulic rod 311 and the piston plate 32. When the hydraulic oil flows inside the piston cylinders 34, it can push the piston head 341 and the piston rod 342 to move and compress one end of the return spring 343. At this time, the piston rod 342 can drive the positioning clamp 38 to move, so that the multiple positioning clamps 38 abut against different positions on both sides of the workpiece. The positioning clamp 38 can rotate around the connecting shaft 36 by the connecting block 37, so that the positioning clamp 38 can generate an inclined angle and fit against the outer wall of the workpiece, thereby increasing the area for clamping and fixing the workpiece and improving the stability of the workpiece. After the workpiece is processed, the piston plate 32 is reset by the first hydraulic rod 311, and the elasticity of the return spring 343 drives the piston head 341, the piston rod 342 and the positioning clamp 38 to move and reset, so that the positioning clamp 38 can be separated from the outer wall of the workpiece.

[0025] Example 2:

[0026] like Figure 1-4As shown, a second hydraulic rod 4 is fixedly installed in the middle of the left side of the L-shaped mounting bracket 1. The telescopic end of the second hydraulic rod 4 extends to the right side of the L-shaped mounting bracket 1 and is fixedly connected to the middle of the left side of the push plate 2. Two guide rods 5 are symmetrically fixedly connected to the left side of the push plate 2. The outer walls of the two guide rods 5 are slidably sleeved on both sides inside the L-shaped mounting bracket 1. Four mounting holes 6 are opened at the bottom of the L-shaped mounting bracket 1. The four mounting holes 6 are distributed at the four corners of the bottom of the L-shaped mounting bracket 1.

[0027] In this embodiment, by using the mounting hole 6, the operator can use screws to install the L-shaped mounting bracket 1 on the double-end face grinder through the mounting hole 6, thereby fixing the workpiece positioning mechanism. The second hydraulic rod 4 can push the push plate 2, the limiting mechanism 3 and the clamped workpiece to move, thereby adjusting the position of the workpiece. While the push plate 2 is moving, it can drive the guide rod 5 to move inside the L-shaped mounting bracket 1. The guide rod 5 can be used to guide the push plate 2 horizontally.

[0028] In summary, as Figure 1-4 As shown, this workpiece positioning mechanism for a double-end face grinder can be used by mounting an L-shaped mounting bracket 1 on the double-end face grinder using screws through mounting holes 6. When positioning the workpiece, the workpiece is placed between multiple positioning clamps 38. At this time, the first hydraulic rod 311 on one side of the two reservoirs 31 drives two piston plates 32 to move inside the two reservoirs 31. The piston plates 32 squeeze the hydraulic oil inside the reservoirs 31 through multiple conduits 33 into multiple piston cylinders 34. As the hydraulic oil flows inside the piston cylinders 34, it pushes the piston head 341 to move. Simultaneously, the piston head 341 compresses the return spring 343 on one side, driving the piston rod 34. 2. The positioning clamps 38 move, causing multiple positioning clamps 38 to abut against different positions on both sides of the workpiece. For example, when the positioning clamps 38 are in contact with the workpiece, the positioning clamps 38 can drive the connecting block 37 to rotate on the outer wall of the connecting shaft 36, so that the positioning clamps 38 can generate an inclined angle and fit against the outer wall of the workpiece. This allows for clamping and fixing of workpieces with irregular shapes on both sides, improving the stability of the workpiece during processing. Then, the push plate 2 is driven to move through the telescopic end of the second hydraulic rod 4. The push plate 2 also drives the guide rod 5 to move inside the L-shaped mounting bracket 1. The push plate 2 can also drive the limiting mechanism 3 and the clamped and fixed workpiece to move, thereby adjusting the position of the workpiece.
