Description

Technical Field

[0001] The utility model belongs to the technical field of vertical lathes, and particularly relates to a multi-surface clamping tooling for a vertical lathe. Background Technique

[0002] Vertical lathes belong to large-scale mechanical equipment and are used for machining 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 discs, wheels and sleeve-shaped workpieces. Thread turning, spherical turning, profiling, milling and grinding can also be carried out with the aid of additional devices. Generally, they can be divided into single-column type and double-column type. The difference between a vertical lathe and an ordinary lathe is that its main shaft is vertical, which is equivalent to standing an ordinary lathe vertically. Since its workbench is in a horizontal position, it is suitable for machining heavy parts with large diameters and short lengths.

[0003] In the prior art, the workpiece clamping device of a vertical lathe usually only uses a chuck for clamping and fixing, and often can only make contact on one side. When the lathe processes a workpiece, the workpiece will generate a certain vibration. Over time, there will be a certain displacement between the chuck and the workpiece, resulting in machining errors of the workpiece.

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

[0005] In view of this, the utility model provides a multi-surface clamping tooling for a vertical lathe. The purpose is that by setting a first heightening member and a second heightening member, when the workpiece is placed on the clamping end face, the first heightening member and the second heightening member will support at the bottom of the workpiece. Subsequently, the chuck vertically arranged on the top of the first heightening member will abut against the outside of the workpiece to radially clamp the workpiece. Subsequently, one end of the top block is pressed on the top of the workpiece, and a screw and a nut are used to tightly pull the top block and the bottom block together, so that the workpiece is axially clamped, realizing multi-surface clamping of the workpiece, thereby improving the clamping efficiency and machining accuracy.

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

[0007] A multi-surface clamping tooling for a vertical lathe includes a clamping end face, which is disc-shaped and used for placing a workpiece;

[0008] The first heightening member, which has an isosceles trapezoid structure and is used for supporting the workpiece, has at least four, and the four first heightening members are distributed in a cross shape on the clamping end face;

[0009] The first clamping member, including a clamping block, is vertically arranged on the top of the first heightening member and is used for radially clamping the workpiece;

[0010] The second heightening member, having a cylindrical structure, is used for supporting the workpiece and is arranged between two adjacent first heightening members;

[0011] The second clamping member, used for axially clamping the workpiece, includes a bottom block and a top block. The bottom block is arranged on one side of the second heightening member facing the edge of the clamping end face, and the top block is arranged parallel above the bottom block, and the top block and the bottom block are connected by bolts and nuts.

[0012] As a preferred technical solution, an opening for clamping the first clamping member is formed at the top of the first heightening member, sliding grooves are formed on the inner walls on both sides of the opening, and the first clamping member further includes sliding blocks corresponding to the sliding grooves.

[0013] Further, a clamping block is arranged at the bottom of the first heightening member, and a clamping groove corresponding to the clamping block is arranged on the clamping end face.

[0014] Further, the clamping groove penetrates through the clamping end face, and a screw rod vertically penetrating through the clamping block is arranged on the first heightening member, and the screw rod penetrates through the clamping groove through the clamping block.

[0015] Further, there are two clamping blocks, and the two clamping blocks are arranged symmetrically and parallel at the bottom of the first heightening member.

[0016] Further, the top block is arranged in a right-angled shape and includes a long right-angled side block and a short right-angled side block.

[0017] Further, the first heightening member and the second heightening member have the same height at the top of the clamping end face.

[0018] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0019] By arranging the first heightening member and the second heightening member, when the workpiece is placed on the clamping end face, the first heightening member and the second heightening member will support at the bottom of the workpiece, and then the clamping block vertically arranged on the top of the first heightening member will abut against the outside of the workpiece to radially clamp the workpiece. Subsequently, one end of the top block presses on the top of the workpiece, and screws and nuts are used to tightly pull the top block and the bottom block together, so that the workpiece is axially clamped, realizing multi-plane clamping of the workpiece, thereby improving the clamping efficiency and machining accuracy.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] In the first embodiment, in the prior art, the workpiece clamping device of a vertical lathe usually only uses a block for fixation, which can usually only restrict the contact on one side of the workpiece. During the turning process, the workpiece may vibrate. Over time, the relative position between the block and the workpiece may shift, resulting in a decrease in machining accuracy and thus causing machining errors of the workpiece.

[0028] Therefore, in order to solve the problem that the existing clamping tooling can only contact one side of the workpiece and has a single clamping effect, and to achieve the function of improving the clamping efficiency, the present utility model discloses a multi - surface clamping tooling for a vertical lathe. Refer to Figures 1 - 4 , which includes a clamping end face 1, in a disc shape, for placing the workpiece; a first heightening member 2, in an isosceles trapezoid structure, for supporting the workpiece, with at least four provided, and the four first heightening members 2 are distributed in a cross shape on the clamping end face 1; a first clamping member 3, including a clamping block 9, vertically arranged on the top of the first heightening member 2, for radially clamping the workpiece; a second heightening member 4, in a cylindrical structure, for supporting the workpiece, arranged between two adjacent first heightening members 2; a second clamping member 5, for axially clamping the workpiece, including a bottom block and a top block 11, the bottom block is arranged on one side of the second heightening member 4 facing the edge of the clamping end face 1, the top block 11 is arranged parallel above the bottom block, and the top block 11 and the bottom block are connected by bolts and nuts;

[0029] When the workpiece is placed on the clamping end face 1, the first heightening piece 2 and the second heightening piece 4 will support at the bottom of the workpiece. Subsequently, the clamping block 9 vertically arranged on the top of the first heightening piece 4 will abut against the outer side of the workpiece to radially clamp the workpiece. Then, one end of the top block 11 is pressed on the top of the workpiece, and screws and nuts are used to tightly pull the top block 11 and the bottom block together, so that the workpiece is axially clamped;

[0030] Thus, due to the support of the first heightening piece 2 and the second heightening piece 4, the workpiece can remain stable during the turning process, avoiding machining errors caused by vibration. In addition, through the combined use of the first clamping piece 3 and the second clamping piece 5, multi-surface clamping of the workpiece is achieved, thereby improving the clamping efficiency and machining accuracy;

[0031] In this embodiment, through the four first heightening pieces 2 distributed in a cross shape, the clamping block 9 located at the top can radially clamp the workpiece from four directions, ensuring the stability of the workpiece in all directions;

[0032] At the same time, by arranging the second heightening piece 4 between two adjacent first heightening pieces 2, the second clamping piece 5 and the first clamping piece 3 can be used in an interlaced manner, further improving the clamping effect on the workpiece;

[0033] In addition, in order to make the workpiece be evenly stressed when supported, the first heightening piece 2 and the second heightening piece 4 have the same height at the top of the clamping end face 1.

[0034] In this embodiment, in order to ensure that the top block 11 has sufficient contact area when clamping the workpiece, so as to evenly apply pressure and avoid deformation or damage of the workpiece during the clamping process. Specifically, the top block 11 is arranged in a right-angled shape, including a long right-angled side block and a short right-angled side block. Among them, the long right-angled side block contacts the top of the workpiece, and the short right-angled side block corresponds to the bottom block to form a stable support structure. The length of the long right-angled side block is designed to be long enough to cover most of the top area of the workpiece to ensure that the applied pressure is evenly distributed. The short right-angled side block plays an auxiliary support role and cooperates with the bottom block to jointly ensure that the top block 11 will not tilt or displace during the clamping process.

[0035] Embodiment 2, on the basis of Embodiment 1, in order to enable this clamping tooling to clamp workpieces of different sizes, refer to Figure 2 and Figure 3 . The present utility model further includes that an opening 6 for clamping the first clamping piece 3 is provided at the top of the first heightening piece 2, and sliding grooves 7 are provided on the inner walls on both sides of the opening 6. The first clamping piece 3 further includes sliding blocks 10 corresponding to the sliding grooves 7;

[0036] In this embodiment, by sliding the slider 10 within the chute 7, the distance adjustment of the first clamping member 3 in the horizontal direction on the first elevation member 2 can be achieved. In this way, when it is necessary to clamp workpieces of different widths, the user only needs to adjust the position of the slider 10 to change the spacing between the first clamping member 3 and the workpiece, thereby adapting to workpieces of different sizes, improving the applicable range of the clamping tooling, and making the clamping process more flexible and convenient.

[0037] Furthermore, to ensure the stability and durability of the clamping tooling during use, both the first elevation member 2 and the second elevation member 4 are made of high-strength materials, such as cemented carbide or special steel. These materials have good wear resistance and compressive strength and can withstand long-term use without deformation or damage.

[0038] In this embodiment, corresponding screw holes are provided between the opening 6 and the slider 10, so that after the first clamping member 3 moves to the designated position, it can be fixed with screws.

[0039] Embodiment 3, on the basis of Embodiment 2, to further expand the versatility of the clamping tooling, refer to Figure 3 , the present utility model further includes that a clamping block 8 is provided at the bottom of the first elevation member 2, and a clamping groove corresponding to the clamping block 8 is provided on the clamping end face 1;

[0040] In this embodiment, through the setting of the clamping groove, the first elevation member 2 can perform reciprocating motion in the horizontal direction on the clamping end face 1 along the clamping groove, so as to achieve the effect of adjusting the spacing between the first elevation member 2 and the workpiece. At the same time, the combined use of the clamping block 8 and the clamping groove improves the stability and positioning accuracy of the first elevation member 2 when moving in the horizontal direction;

[0041] Furthermore, in order to fix the first elevation member 2 on the clamping end face 1, the clamping groove penetrates through the clamping end face 1, and a screw rod vertically penetrating through the clamping block 8 is provided on the first elevation member 2. The screw rod penetrates through the clamping groove through the clamping block 8. It can be understood that since the screw rod penetrates through the clamping groove and the clamping groove penetrates through the clamping end face 1, when the first elevation member 2 moves to the designated position, the user can install a nut on the screw rod extending to the bottom of the clamping end face 1 to fix the first elevation member 2;

[0042] Secondly, by passing the screw rod through the clamping block 8, the screw rod can be made more stable to avoid the loosening of the screw rod;

[0043] Optionally, a scale table can be provided on the outside of the clamping groove to facilitate keeping the four first elevation members 2 consistent when moving.

[0044] In one embodiment, there are two clamping blocks 8, and the two clamping blocks 2 are arranged symmetrically and parallel to each other at the bottom of the first elevation member 2. With this arrangement, the first elevation member 2 can be fixed more stably on the clamping end face 1 and is not likely to sway left and right.

[0045] In this embodiment, the second elevation member 4 can also be installed on the clamping end face 1 by using the above method, so that the second elevation member 4 can also cooperate with the first elevation member 2 to move horizontally on the clamping end face 1.

[0046] In this specification, the various embodiments are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same and similar parts among the various embodiments, reference can be made to each other.

[0047] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
