Description

Technical Field

[0001] The utility model belongs to the technical field of vertical lathes, and in particular relates to a multi-point clamping device for a vertical lathe. Background Art

[0002] Vertical lathes are large-scale mechanical equipment used to process large and heavy workpieces with large radial dimensions and relatively small axial dimensions and complex shapes, such as cylindrical surfaces, end faces, conical surfaces, cylindrical holes, conical holes, etc. of various disks, wheels and sleeves. They can also be used for threading, spherical surface turning, profiling, milling and grinding with the help of additional devices. They can generally be divided into single-column and double-column types. The difference between a vertical lathe and an ordinary lathe is that its spindle is vertical, which is equivalent to standing an ordinary lathe upright. Since its worktable is in a horizontal position, it is suitable for processing heavy parts with large diameter and short length.

[0003] In the prior art, the workpiece clamping device of a vertical lathe usually uses multiple clamping blocks for multi-point clamping and fixing. However, when clamping the workpiece, in order to ensure that the clamping force at each end point of the workpiece is balanced, the user needs to repeatedly adjust each clamping block so that the workpiece can be fixed in the middle position of the clamping tray to facilitate subsequent processing. As a result, the clamping process is more cumbersome, reducing the clamping and processing efficiency.

[0004] The above information disclosed in the background technology section is only used to enhance the understanding of the background technology of the technology described in this article. Therefore, the background technology may contain certain information that does not form the prior art known in this country for those skilled in the art. Utility Model Content

[0005] In view of this, the utility model provides a multi-point clamping device for a vertical lathe, the purpose of which is that, through the arrangement of the clamping block and the top block, when it is necessary to clamp an annular workpiece, the user can place the inner side of the annular workpiece against the top block on the top of the clamping seat, and then the user only needs to adjust the clamping block in sequence to squeeze the outer side of the workpiece to complete the clamping work. Since the top block fits tightly against the inner side of the workpiece, the workpiece itself will not be displaced when the clamping block applies pressure to the outer side of the workpiece. Therefore, unilateral pressure will not destroy the force balance of the workpiece. Compared with the existing clamping methods, this clamping device only needs to sequentially adjust the clamping block to complete the clamping, without the need to adjust the position of the clamping block multiple times, thereby simplifying the clamping process and improving processing efficiency.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A multi-point clamping device for a vertical lathe, comprising a clamping plate for placing an annular workpiece;

[0008] A clamping seat, arranged on the clamping plate, for clamping the annular workpiece placed on the clamping plate;

[0009] The top of the clamping seat is provided with a clamping block for contacting the outer side of the annular workpiece, and the end of the clamping seat facing the center of the clamping disk is provided with a top block for contacting the inner side of the annular workpiece, wherein the top block and the clamping block are parallel to each other.

[0010] As a preferred technical solution, a clamping groove is provided on the top of the clamping seat, a moving block is provided at the bottom of the clamping block, and the moving block is clamped in the clamping groove, wherein a lead screw is provided in the clamping groove and passes through the moving block.

[0011] Furthermore, the top blocks are arranged in parallel on both sides of the clamping groove opening, wherein both sides of the clamping groove opening are also provided with adjustment grooves for adjusting the position of the top blocks.

[0012] Furthermore, a latch is provided between the top block and the adjusting slot.

[0013] Furthermore, the clamping plate is also provided with a support column for supporting the annular workpiece, wherein the support column is arranged between two adjacent clamping seats.

[0014] Furthermore, the clamping plate is also provided with a through groove for fixing the clamping seat and the support column.

[0015] Furthermore, a plurality of vertically parallel strip-shaped protrusions are provided on one side of the clamping block facing the top block.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0017] By setting the clamping block and the top block, when the annular workpiece needs to be clamped, the user can place the inner side of the annular workpiece against the top block on the top of the clamping seat, and then the user only needs to adjust the clamping block in sequence to squeeze the outer side of the workpiece to complete the clamping work. Since the top block fits tightly against the inner side of the workpiece, the workpiece itself will not move when the clamping block applies pressure to the outer side of the workpiece. Therefore, unilateral pressure will not destroy the force balance of the workpiece. Compared with the existing clamping method, this clamping device only needs to adjust the clamping block in sequence to complete the clamping, without the need to adjust the position of the clamping block multiple times, thereby simplifying the clamping process and improving processing efficiency.

[0023] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment 1

[0025] In the prior art, the workpiece clamping device of a vertical lathe usually uses multiple clamping blocks to achieve multi-point clamping and fixation. However, when clamping a workpiece, the operator must repeatedly adjust each clamping block to ensure that both ends of the workpiece are evenly stressed, so as to accurately fix the workpiece at the center of the material clamping disc for subsequent processing. This process makes the clamping operation complicated, thereby reducing the clamping and processing efficiency.

[0026] Therefore, in order to solve the problem that the existing clamping device has more processes during use, resulting in reduced clamping and processing efficiency, and to achieve the function of rapid clamping and improved work efficiency, the present utility model discloses a multi-point clamping device for a vertical lathe. Refer to Figures 1 - 3 , which includes a material clamping disc 1 for placing a ring-shaped workpiece, and a clamping seat 2 arranged on the material clamping disc 1 for clamping the ring-shaped workpiece placed on the material clamping disc 1. The top of the clamping seat 2 is provided with a clamping block 6 for contacting the outer side of the ring-shaped workpiece, and one end of the clamping seat 2 facing the center of the material clamping disc 1 is provided with a top block 8 for contacting the inner side of the ring-shaped workpiece. Among them, the top block 8 and the clamping block 6 are parallel to each other;

[0027] When it is necessary to clamp an annular workpiece, the user can place the inner side of the annular workpiece against the top block 8 on the top of the clamping seat 2, and then the user only needs to adjust the clamping block 6 in sequence to squeeze the outer side of the workpiece to complete the clamping work. Because the top block 8 is in contact with the inner side of the workpiece, when the clamping block 6 squeezes the outer side of the workpiece, the workpiece as a whole will not move, so that the pressure on a single side will not affect the force balance of the workpiece. Compared with the existing clamping process, the clamping device only needs to adjust the clamping block 6 in sequence to complete the clamping work, and there is no need to repeatedly adjust the position of the clamping block 6, thereby reducing the clamping process and improving the processing efficiency.

[0028] At the same time, by using the clamping block 6 in conjunction with the top block 8, the inner and outer sides of the workpiece can be clamped at the same time. Compared with the existing clamping operation performed only by contacting the outer side of the workpiece, the clamping device can more effectively fix the workpiece, avoiding the workpiece from shifting or vibrating during the machining process, thereby improving the machining accuracy.

[0029] In addition, in order to allow the clamping block 6 to be smoothly adjusted in the clamping seat 2, a clamping groove 5 is further provided at the top of the clamping seat 2, and a moving block 11 is provided at the bottom of the clamping block 6, and the moving block 11 is clamped in the clamping groove 5, wherein a lead screw 7 is further provided in the clamping groove 5. The lead screw 7 is passed through the moving block 11, and through the rotation of the lead screw 7, the moving block 11 can drive the clamping block 6 to move in the clamping groove 5, thereby adjusting the clamping force and position of the clamping block 6;

[0030] In one embodiment, the lead screw 7 can be matched with an existing rotating motor, so that the lead screw 7 does not need to be rotated by manpower, further improving the clamping efficiency.

[0031] In this embodiment, in order to prevent the top block 8 from blocking the movement of the clamping block 6, the top block 8 is arranged in parallel on both sides of the opening of the clamping groove 5. Through this arrangement, the top block 8 will not block the clamping block 6 moving in the clamping groove 5. At the same time, under this arrangement, when the top block 8 and the clamping block 5 are attached to the inner and outer sides of the workpiece, a triangular structure can be formed between the contact points of the top block 8 and the clamping block 5 on the workpiece, which further improves the clamping stability of the workpiece.

[0032] In this embodiment, in order to improve the clamping effect of the workpiece, the clamping block 6 is provided with a plurality of upper and lower parallel strip protrusions on the side facing the top block 8. Through this arrangement, the friction between the clamping block 6 and the workpiece is increased, which facilitates the clamping of the workpiece.

[0033] Embodiment 2

[0034] On the basis of the first embodiment, in order to further improve the applicability of the top block 8 to workpieces of different sizes, refer to Figure 2 and Figure 3, the utility model further includes an adjustment groove 10 for adjusting the position of the top block 8. Specifically, adjustment grooves 10 for adjusting the position of the top block 8 are also provided on both sides of the opening of the clamping groove 5, and a pin 9 is inserted between the top block 8 and the adjustment groove 10;

[0035] In this embodiment, by adjusting the position of the pin 9, the distance between the top block 8 and the clamping block 5 can be changed, so as to adapt to workpieces of different thicknesses. When it is necessary to clamp an annular workpiece with a longer inner diameter, the operator can insert the pin 9 into one end of the adjustment groove 10 close to the clamping block 5, so that the top block 8 is far from the center of the material clamping plate 1, so that the annular workpiece with a larger inner diameter can be smoothly placed on the material clamping plate 1 against the top block 8. When it is necessary to clamp an annular workpiece with a smaller inner diameter, the operator can insert the pin 9 into one end of the adjustment groove 10 far from the clamping block 5, so that the top block 8 is close to the center of the material clamping plate 1, so that the annular workpiece with a smaller inner diameter can be tightly clamped by the top block 8 and the clamping block 6, ensuring that the workpiece will not shift during the processing;

[0036] It can be understood that jacks corresponding to the pin 9 are provided on the bottom inner wall of the adjustment groove 10. This setting can facilitate the adjustment of the position of the top block 8. The user only needs to pull out the pin 9 to move the top block 8, without using other tools for disassembly.

[0037] In addition, in order to further improve the stability and clamping effect of the clamping device, a support column 3 for supporting the annular workpiece is further provided on the material clamping plate 1. Among them, the support column 3 is arranged between two adjacent clamping seats 2, and the support column 3 is a cylinder. Through this setting, it can help prevent the workpiece from deforming or displacing due to uneven force during processing, thereby improving the processing accuracy.

[0038] Furthermore, in order to fix the clamping seat 2 and the support column 3 on the material clamping plate 1, a through groove 4 for fixing the clamping seat 2 and the support column 3 is further provided on the material clamping plate 1. At the same time, screws are provided at the bottoms of the clamping seat 2 and the support column 3. By passing the screws at the bottoms of the clamping seat 2 and the support column 3 through the through groove 4, and then screwing nuts into the screws, the clamping seat 2 and the support column 3 are fixed on the material clamping plate 1;

[0039] In addition, through the above structure, the user can first loosen the nut, and then push the clamping seat 2 or the support column 3 along the through groove 4, so as to adjust the relative position between the clamping seat 2 and the support column 3.

[0040] In summary, combining Embodiment 1 and Embodiment 2, the working principle of the clamping device is as follows: First, the user places the annular workpiece on the material clamping plate 1, ensuring that the inner side of the workpiece fits against the top block 8. Subsequently, by sequentially adjusting the clamping blocks 6 to squeeze the outer side of the workpiece, rapid clamping is achieved. Due to the presence of the top block 8, the workpiece will not move during the clamping process, thus ensuring force balance. The clamping force and position of the clamping blocks 6 are adjusted by the lead screw 7 to ensure that the workpiece is evenly clamped.

[0041] When it is necessary to adapt to annular workpieces of different sizes, the operator can change the distance between the top block 8 and the clamping blocks 6 by adjusting the position of the pin 9. In this way, the device can clamp workpieces of different sizes, and at the same time, it can clamp both the inner and outer sides of the annular workpiece, which helps to reduce offset or vibration during the processing.

[0042] To further improve the stability and clamping effect of the clamping device, the support columns 3 are arranged on the material clamping plate 1 to support the annular workpiece. The arrangement of the support columns 3 helps to prevent the workpiece from deforming or displacing due to uneven force during the processing, thereby improving the processing accuracy.

[0043] Finally, through the combined use of the through groove 4 and the screw, the operator can easily adjust the relative position between the clamping seat 2 and the support columns 3 to adapt to workpieces of different sizes. This design not only improves the applicability of the clamping device but also makes the clamping device more flexible and convenient in actual use.
