Figure 1 and Figure 2The universal cylindrical grinder for processing mold workpieces includes a worktable 1, on which a connecting table 2 is detachably provided. The connecting table 2 is located between the headstock and the tailstock. The length direction of the connecting table 2 is perpendicular to the length direction of the worktable 1, and the connecting table 2 extends out of the worktable 1. An intermediate seat 5 is provided on the connecting table 2, on which a support table 3 for supporting the workpiece is slidably provided. The support table 3 is slidably provided in the vertical direction. The center line of the support table 3 is located in the vertical plane where the top of the headstock and the top of the tailstock are located. An arc groove 11 for fitting the workpiece is provided on the support table 3. The arc groove 11 is located in the middle of the support table 3. The center line of the arc groove 11 and the center line of the support table 3 are located in the same vertical plane. The setting of the arc groove 11 makes it difficult for the workpiece to roll; an adjusting member 4 for adjusting the sliding of the support table 3 is provided on the intermediate seat 5.

[0028] During operation, the connecting table 2 is installed on the workbench 1, and then the workpiece is lifted and placed in the arc groove 11. Since the center line of the support table 3 is located on the vertical plane of the headstock and the tailstock top, the center line of the cylindrical and conical workpieces placed in the arc groove 11 is also located on the vertical plane of the headstock and the tailstock top. Then, the support table 3 is driven to slide upward to the required height through the adjustment member 4 to align the center of the workpiece with the top. At this time, the headstock and the tailstock are driven to move to fix the workpiece, and then the support table 3 is driven downward through the adjustment member 4 to disengage the arc groove 11 from the workpiece, thereby facilitating the alignment of the workpiece with the top. There is no need to manually lift the workpiece and constantly adjust the position, which helps to reduce labor intensity and save workers' effort in operation. At the same time, it is convenient for operators to free their hands to perform other operations.

[0029] Reference Figure 2 and Figure 3 In order to facilitate the adjustment of the sliding of the support platform 3, the adjustment member 4 includes a screw rod 41 and an electric motor 42. The screw rod 41 is rotatably penetrated on the middle seat 5. Two screw rods 41 are arranged opposite to each other. The rotation axis of the screw rod 41 is parallel to the sliding direction of the support platform 3. The support platform 3 is threadedly sleeved on the top of the two screw rods 41. The electric motor 42 corresponds to the screw rod 41 one by one. The electric motor 42 is embedded in the middle seat 5. The screw rod 41 is coaxially fixed with the output shaft of the corresponding electric motor 42. The electric motor 42 is used for wireless connection with the controller for controlling the machine tool.

[0030] When the support platform 3 needs to be driven to slide, the electric motor 42 is started by operating the controller on the machine tool. The electric motor 42 drives the screw 41 to rotate. The rotation of the screw 41 drives the support platform 3 to slide upward or downward, which helps to adjust the position of the workpiece.

[0031] Reference Figure 2 and Figure 3Two connecting blocks 12 are relatively fixed on the bottom wall of the connecting platform 2, and a connecting groove 13 for plugging and matching with the connecting blocks 12 is provided on the surface of the workbench 1. The connecting groove 13 is located between the headstock and the tailstock. The connecting block 12 and the connecting groove 13 are plugged in and matched to realize the detachable connection between the connecting platform 2 and the workbench 1, which facilitates the installation and removal of the connecting platform 2 and the workbench 1.

[0032] Reference Figure 2 and Figure 3 The middle seat 5 is slidably connected to the connecting table 2, and a guide rail 15 is fixed on the upper surface of the connecting table 2. The length direction of the guide rail 15 is parallel to the length direction of the connecting table 2. The middle seat 5 slides with the guide rail 15. The sliding direction of the middle seat 5 is perpendicular to the length direction of the workbench 1, and the sliding direction of the middle seat 5 is perpendicular to the sliding direction of the support table 3. One end of the connecting table 2 close to the grinding wheel frame is fixedly connected to the limiting plate 6, and the limiting plate 6 is located on the side of the middle seat 5 close to the grinding wheel frame. When the middle seat 5 abuts against the limiting plate 6, the center line of the arc groove 11 is located on the vertical plane of the top of the headstock and the tailstock.

[0033] When it is necessary to install the workpiece, the middle seat 5 is moved towards the direction close to the limit plate 6, so that the middle seat 5 abuts against the limit plate 6, which is convenient for the alignment of the workpiece; when the workpiece is fixed, the middle seat 5 is moved towards the direction away from the limit plate 6, so that the support table 3 is away from the workpiece, so as to provide enough space for the grinding of the workpiece; when the workpiece needs to be removed after processing, the middle seat 5 is moved towards the direction close to the limit plate 6, so that the middle seat 5 abuts against the limit plate 6, which is convenient for receiving the workpiece and is not easy to cause mistakes such as falling due to the workpiece being too heavy.

[0034] Reference Figure 2 and Figure 3 A baffle plate 7 is detachably connected to the support platform 3. The baffle plate 7 is located on the side of the support platform 3 close to the grinding wheel frame. The upper surface of the baffle plate 7 is higher than the upper surface of the support platform 3. Extension plates 8 are slidably penetrated on the opposite sides of the baffle plate 7. The sliding direction of the extension plate 8 is parallel to the length direction of the workbench 1; an L-shaped hook 9 is fixedly connected to the side of the baffle plate 7 close to the support platform 3, and a hanging groove 10 is provided on the side of the support platform 3 close to the grinding wheel frame to cooperate with the hook 9. The detachable connection between the baffle plate 7 and the support platform 3 is realized by the hanging cooperation between the hook 9 and the hanging groove 10.

[0035] When the workpiece is fixed, the middle seat 5 moves to the end of the connecting table 2 away from the limit plate 6, and the hook 9 on the baffle plate 7 is hung on the hanging groove 10 on the side of the support table 3 close to the grinding wheel frame, so that the baffle plate 7 blocks the support table 3, and then the extension plate 8 is slid in the direction away from the baffle plate 7, and the extension plate 8 moves to the headstock or tailstock on the corresponding side. The baffle plate 7 and the extension plate 8 help to block the cooling water splashing during the workpiece grinding process.

[0036] Reference Figure 2 and Figure 3 , a scale 14 is slidably arranged on the middle seat 5, the scale 14 is arranged in the vertical direction, the sliding direction of the scale 14 is parallel to the sliding direction of the middle seat 5, a slider (not shown in the figure) is fixed on the scale 14, the slider is a T-shaped block, and a slide groove 16 that slides with the slider is provided on the side wall of the middle seat 5. When the workpiece needs to be placed in the arc groove 11, the scale 14 is slid, and the scale 14 is moved to the side of the support table 3 away from the limit plate 6, and then the workpiece is lifted and placed on the arc groove 11, and the scale 14 is moved in the direction close to the workpiece so that the outer wall of the workpiece in the horizontal direction abuts against the scale 14, and the height of the center of the workpiece is read; the height of the top on the headstock and the tailstock is known, which helps to quickly adjust the height of the support table 3 so that the center of the workpiece is aligned with the top on the headstock and the tailstock.

[0037] The implementation principle of the embodiment of the present application is as follows: when working, the connecting block 12 on the connecting table 2 is plugged into the connecting groove 13 on the workbench 1 to realize the installation of the connecting table 2, then the baffle 7 is removed from the support table 3, and the middle seat 5 is moved along the guide rail 15 toward the direction close to the limit plate 6 until the middle seat 5 abuts against the limit plate 6, at which time the center line of the arc groove 11 is located on the two top vertical planes; then the workpiece is lifted and placed in the arc groove 11, because the center line of the arc groove 11 is located in the two top vertical planes, the center line of the cylindrical and conical workpieces placed in the arc groove 11 can also be located in the two top vertical planes, and then the two electric motors 42 are started by controlling the machine tool, and the electric motor 42 drives the corresponding screw 41 to rotate, and the screw 41 drives the support The support table 3 slides upward to the required height so that the center of the workpiece is aligned with the top, and at this time the headstock and the tailstock are driven to move to fix the workpiece; then the two electric motors 42 are started, and the electric motors 42 drive the corresponding screws 41 to rotate, and the screws 41 drive the support table 3 to move downward, so that the arc groove 11 is disengaged from the workpiece, and then the middle seat 5 is moved in the direction away from the limit plate 6, so that the middle seat 5 drives the support table 3 away from the workpiece, and then the hook 9 on the baffle 7 is engaged with the hanging groove 10 on the support table 3, and the extension plate 8 is pulled in the direction away from the baffle 7, so that the baffle 7 and the extension plate 8 cover the gap between the headstock and the tailstock, so that the cooling water in the grinding process is not easy to splash out. This process does not require manual lifting of the workpiece to continuously adjust the position, which helps to reduce labor intensity and make the operation labor-saving.

[0038] After the workpiece is ground, the baffle 7 is removed from the support table 3, and then the middle seat 5 is moved along the guide rail 15 toward the direction close to the limit plate 6 until the middle seat 5 abuts against the limit plate 6, and then the two electric motors 42 are started by controlling the machine tool. The electric motor 42 drives the corresponding screw 41 to rotate, and the screw 41 drives the support table 3 to slide upward to the required height, so that the workpiece abuts against the arc groove 11. At this time, the headstock and the tailstock are driven away from each other to loosen the workpiece, which is convenient for removing the workpiece.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
