[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] Before driving the clamping movable seat 1 and the clamping movable seat 2 to move, the clamping orientation control component can be started according to the size of the workpiece. For example, a larger workpiece may need to have more and more dispersed parts processed, and the number of processing steps increases accordingly. At this time, the possibility of the workpiece shifting or shaking will increase. Therefore, it is necessary to provide more effective clamping for the workpiece. Under the adjustment of the clamping orientation control component, not only can the clamping plates 1 and 2 on the clamping movable seat 1 and the clamping movable seat 2 clamp the two sides of the workpiece, but the clamping part on the clamping orientation control component can also clamp the other two opposite sides of the workpiece, thereby realizing the clamping operation on the four sides of the workpiece. It is beneficial to ensure the stability of the workpiece during the processing operation. When the workpiece is of medium size and the processing procedure is relatively simple, for example, only simple drilling processing is required (but when the workpiece size is small, due to factors such as the clamping contact area, the workpiece is also prone to loosening during the processing). Then, the clamping position control component is started again, which can drive the clamping force adjustment component to move, and the clamping force adjustment component will increase the thrust on the second clamping plate. As the displacement of the clamping movable seat one and the clamping movable seat two increases (indicating that the size of the workpiece is smaller), the force generated by the clamping force adjustment component on the second clamping plate increases. Since the size of the second clamping plate is smaller than that of the first clamping plate, The clamping force of the second clamping plate on the workpiece can be gradually increased according to the size of the workpiece, and during the clamping process, the clamping position control component can be controlled to perform corresponding actions through the feedback signal of the clamping between the second clamping plate and the workpiece, so as to avoid over-clamping or insufficient clamping force, thereby ensuring the stability of smaller workpieces during the entire processing process. For smaller workpieces, the first clamping plate may not be able to play a good clamping role (for example, due to the larger size of the first clamping plate, it is not conducive to processing operations and the stability of the workpiece when clamping a smaller workpiece. For example, the minimum distance between the two first clamps is limited, and smaller workpieces cannot be clamped). At this time, in the clamping Under the joint action of the position control component and the clamping force adjustment component, the second clamping plate can be extended a certain distance outside the first clamping plate (equivalent to reducing the minimum distance between the two first clamping plates, so that smaller workpieces can be clamped), and because the size of the second clamping plate is smaller than that of the first clamping plate, smaller workpieces can be clamped (different clamping states can be achieved for larger, medium and smaller workpieces, and the corresponding clamping effects can be guaranteed, thereby improving the practicality and flexibility of the equipment). The operation is simple, and different clamping states can be achieved for different sizes, and the clamping effects under different clamping states can be guaranteed, thereby providing a guarantee for subsequent processing operations and providing convenience for the staff.

DETAILED DESCRIPTION

[0056] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0057] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0058] See also Figure 1-Figure 13 A lathe fixture provided by an embodiment of the present invention includes a fixture support plate 2, on which a workpiece processing base 3 is fixedly mounted, and further includes:

[0059] A clamping movable seat 1 4 and a clamping movable seat 2 8, wherein the clamping movable seat 1 4 and the clamping movable seat 2 8 are both located on the fixture support plate 2 and are respectively located on both sides of the workpiece processing base 3, and a clamping plate 10 is provided on the clamping movable seat 1 4 and the clamping movable seat 2 8, a clamping plate 2 11 is inserted in the middle of the clamping plate 10, and the clamping plate 2 11 is slidably connected with the clamping plate 10;

[0060] and a clamping control mechanism, wherein the clamping control mechanism is respectively connected to the clamp support plate 2, the clamping movable seat 1 4, the clamping movable seat 2 8 and the clamping plate 2 11, wherein the clamping control mechanism includes a clamping position control component and a clamping force adjustment component;

[0061] The clamping position control component is connected to the clamp support plate 2 and the clamping movable seat 8 respectively, and the clamping force adjustment component is connected to the clamping movable seat 1 4 and the clamping plate 2 11 respectively, and is detachably connected to the clamping position control component.

[0062] When processing the workpiece, first, the workpiece can be placed on the workpiece processing base 3, and the clamping movable seat 1 4 and the clamping movable seat 2 8 can be driven to move simultaneously on the fixture support plate 2 toward the workpiece processing base 3, so that the clamping plate 1 10 and the clamping plate 2 11 clamp the two side parts of the workpiece, wherein the specific clamping structure on the clamping plate 10 and the clamping plate 2 11 can be selected according to the shape and structure of the workpiece, and the corresponding clamping structure is connected to the clamping plate 10 and the clamping plate 2 11 by bolt connection, so as to ensure the subsequent clamping effect. No further details are given here. Before driving the clamping movable seat 1 4 and the clamping movable seat 2 8 to move, the clamping orientation control component can be started according to the size of the workpiece. For example, for a larger workpiece, There may be many parts that need to be processed and the processing parts are relatively scattered, and the number of processing steps increases accordingly. At this time, the possibility of the workpiece shifting or shaking will increase. Therefore, it is necessary to provide more effective clamping for the workpiece. Under the adjustment of the clamping orientation control component, not only can the clamping plate 10 and the clamping plate 2 11 on the clamping movable seat 1 4 and the clamping movable seat 2 8 clamp the two sides of the workpiece, but the clamping part on the clamping orientation control component can also clamp the other two opposite sides of the workpiece, thereby realizing the clamping operation on the four sides of the workpiece, which is beneficial to ensure the stability of the workpiece during the processing operation. When the workpiece size is medium and the processing steps are relatively simple, for example, only simple drilling processing is required (but when the workpiece size is small, Due to the influence of factors such as the clamping contact area, the workpiece is prone to loosening during the processing). In this case, the clamping position control component is started again, which can drive the clamping force adjustment component to operate, and the clamping force adjustment component will increase the thrust on the clamping plate 11. As the displacement of the clamping movable seat 14 and the clamping movable seat 8 increases (indicating that the size of the workpiece is smaller), the force generated by the clamping force adjustment component on the clamping plate 11 becomes greater. Since the size of the clamping plate 11 is smaller than that of the clamping plate 10, the clamping force of the clamping plate 11 on the workpiece can be gradually increased according to the size of the workpiece. In addition, during the clamping process, the clamping position control component can be controlled to perform the corresponding operations through the feedback signal of the clamping between the clamping plate 11 and the workpiece. The corresponding actions are performed to avoid over-clamping or insufficient clamping force, thereby ensuring the stability of smaller workpieces during the entire processing process. For smaller workpieces, the clamping plate 10 may not be able to play a good clamping role (for example, due to the large size of the clamping plate 10, it is not conducive to processing operations and the stability of the workpiece when clamping a smaller workpiece. For example, the minimum distance between the two clamping plates 10 is limited, and smaller workpieces cannot be clamped). At this time, under the joint action of the clamping direction control component and the clamping force adjustment component, the clamping plate 11 can be extended out of the outside of the clamping plate 10 by a certain distance (equivalent to reducing the minimum distance between the two clamping plates 10, so that smaller workpieces can be clamped).And because the size of the second clamping plate 11 is smaller than that of the first clamping plate 10, it can clamp smaller workpieces (it can realize different clamping states for workpieces of larger, medium and smaller sizes, and can ensure the corresponding clamping effects, which improves the practicality and flexibility of the equipment). It is easy to operate, can realize different clamping states for different sizes, and can ensure the clamping effects under different clamping states, which provides guarantee for subsequent processing operations and convenience for the staff.

[0064] Two of the sliding sleeves 16 are fixedly connected to the clamping movable seat 1 4 , and the other two of the sliding sleeves 16 are fixedly connected to the clamping movable seat 2 8 .

[0065] The fixture support plate 2 is also provided with two limiting slide grooves 24, each limiting slide groove 24 is slidably installed with a slider 25, and the two sliders 25 are respectively fixedly connected to the clamping movable seat 1 4 and the clamping movable seat 2 8;

[0069] A driving gear 27, wherein the driving gear 27 is fixedly connected to an output end of the clamping motor 26;

[0070] And a transmission unit, the number of the transmission units is two sets, the two sets of the transmission units are respectively located on both sides of the driving gear 27, and are both connected to the fixture support plate 2, and the two sets of the transmission units are respectively connected to the two sliders 25.

[0071] The transmission unit comprises:

[0072] A guide slide 18, wherein the guide slide 18 is fixedly connected to the fixture support plate 2;

[0074] And a connecting rod 29 , wherein the connecting rod 29 is fixedly mounted on the moving rack 28 , and the connecting rod 29 is also fixedly connected to the sliding block 25 .

[0075] When clamping the workpiece, starting the clamping motor 26 can drive the active gear 27 to rotate and drive the two moving racks 28 to slide on the two guide slides 18 at the same time. When the moving rack 28 moves, it can drive the two connecting rods 29 to move synchronously, so that the two sliders 25 can slide in the two limiting slide grooves 24 respectively, wherein the structure of the limiting slide grooves 24 and the sliders 25 can adopt the form of matching sliding blocks and slide rails, so as to ensure the smooth movement of the sliders 25. During the movement of the two sliders 25, the clamping moving seat 1 4 and the clamping moving seat 2 8 can be driven to move toward the direction of the workpiece processing base 3 at the same time, and through the set sliding sleeve 16 and smooth support rod 17, during the movement of the clamping moving seat 1 4 and the clamping moving seat 2 8, the sliding sleeve 16 can slide on the smooth support rod 17, thereby ensuring the stability of the clamping process, which will not be elaborated here.

[0079] And an adjustment control unit, which is connected to the clamping movable seat 2 8 and to the other end of the swing driving rod 14 .

[0080] The regulating control unit comprises:

[0081] An adjusting slot plate 19, wherein the adjusting slot plate 19 is fixedly connected to the clamping movable seat 2 8, and a driving member 20 is also fixedly mounted on the adjusting slot plate 19;

[0082] A sliding plate 21, wherein the sliding plate 21 is slidably mounted in the adjusting slot plate 19 and is fixedly connected to the output end of the driving member 20, and a control guide groove 22 is further provided on the sliding plate 21;

[0083] And a driving column 23, wherein the driving column 23 is fixedly mounted on the other end of the swing driving rod 14, and the driving column 23 is also inserted into the control guide groove 22 and slidably connected with the control guide groove 22.

[0084] See also Figure 1-Figure 13 , the clamping force adjustment component comprises:

[0085] A telescopic cylinder sleeve 5, wherein the telescopic cylinder sleeve 5 is fixedly mounted on the clamping movable seat 4;

[0086] A telescopic control rod 6, wherein the telescopic control rod 6 is inserted into the telescopic cylinder sleeve 5 and is slidably connected to the telescopic cylinder sleeve 5, and the other end of the telescopic control rod 6 is detachably connected to the adjusting inclined block 12;

[0087] And a pulling unit, wherein the pulling unit is respectively connected with the clamping movable seat 1 4, the telescopic control rod 6 and the clamping plate 2 11.

[0088] The pulling unit comprises:

[0089] A clamping and adjusting chamber 7, wherein the clamping and adjusting chamber 7 is fixedly mounted on the clamping and moving seat 1 4 and is arranged opposite to the clamping plate 2 11, and a moving support plate 33 is also slidably mounted in the clamping and adjusting chamber 7;

[0090] A telescopic rod 31, the two ends of which are respectively fixedly connected to the second clamping plate 11 and the movable support plate 33, and a spring 32 is sleeved on the telescopic rod 31, the two ends of which are respectively fixedly connected to the second clamping plate 11 and the movable support plate 33;

[0091] A fixed pulley 34, wherein the number of the fixed pulleys 34 is multiple, and the multiple fixed pulleys 34 are distributed and installed in the cavity opened on the clamping movable seat 1 4, wherein the telescopic cylinder sleeve 5 is connected to the cavity;

[0092] And a steel wire rope 35, one end of which is fixedly connected to the movable support plate 33, and the other end of the steel wire rope 35 is passed around the plurality of fixed pulleys 34 and is fixedly connected to the end of the telescopic control rod 6.

[0093] Before clamping the workpiece, the driving member 20 can be started according to the size of the workpiece. The driving member 20 can push or pull the sliding plate 21 to slide in the adjusting groove plate 19. During the movement of the sliding plate 21, the contact position of the driving column 23 and the control guide groove 22 can be changed. The control guide groove 22 is composed of two parts, namely a straight groove part and an inclined groove part. When the driving column 23 moves in the straight groove part, the swing driving rod 14 is in a stationary state, and the adjusting inclined block 12 and the clamping roller 13 are also in a stationary state. In this working position state, the corresponding workpiece of medium or small size is processed. At this time, as the clamping movable seat 1 4 and the clamping movable seat 2 8 approach each other, the stationary adjusting inclined block 12 can pass over the vertical plate of the clamping movable seat 1 4 and reach a position close to the vertical plate. The end of the telescopic control rod 6 is positioned such that the driving column 23 just ends its movement in the straight groove portion and immediately enters the inclined groove portion. Under the guiding action of the inclined groove portion, the swing driving rod 14 can rotate around the rotating shaft 15 and the adjusting bevel block 12 can rotate synchronously. As the clamping movable seat 1 4 and the clamping movable seat 2 8 continue to move, the inclined surface of the adjusting bevel block 12 will contact the end of the telescopic control rod 6 and exert an extrusion effect on the telescopic control rod 6, thereby allowing the telescopic control rod 6 to move in the telescopic cylinder sleeve 5. During the movement of the telescopic control rod 6, the steel wire rope 35 will also be driven to move. Under the guiding action of multiple fixed pulleys 34 (a fixed pulley 34 can be provided at each turning point of the steel wire rope 35, not shown in the figure), the steel wire rope 35 will pull the movable support plate 33 It slides in the clamping adjustment bin 7 and generates a thrust on the clamping plate 11 through the spring 32, thereby increasing the clamping force of the clamping plate 11 on the medium workpiece, or making the clamping plate 11 extend out of the clamping plate 10 and clamping a smaller workpiece. The clamping movable seat 8 is also fixedly mounted with the clamping adjustment bin 7, and the clamping adjustment bin 7 on the clamping movable seat 8 is also fixedly mounted with a telescopic cylinder 9, and the telescopic cylinder 9 can be in the form of an air cylinder or an electric push cylinder, which can directly push the clamping plate 11 on the clamping movable seat 8 to move, so as to cooperate with the clamping plate 11 on the clamping movable seat 4, so that smaller workpieces can be clamped smoothly, which will not be described in detail here. In addition, a plurality of deformation detectors 30 are also fixedly mounted on the clamping plate 11, and The deformation detector 30 can be in the form of a strain gauge sensor, and can detect the clamping state of the clamping plate 10 and the clamping plate 2 11. For example, since the clamping force of the clamping plate 2 11 is greater than that of the clamping plate 10, when the contact portion of the clamping plate 10 and the clamping plate 2 11 on the surface of a medium-sized workpiece is deformed, it means that the clamping force of the clamping plate 2 11 may be excessive. At this time, the deformation detector 30 can control the drive member 20 to start and push the sliding plate 21 to move in the adjusting slot plate 19 to change the thrust of the adjusting bevel block 12 on the telescopic control rod 6, thereby reducing the clamping force of the clamping plate 2 11 on the workpiece. In addition, a plurality of distance detectors 36 are also provided on the movable support plate 33, which can detect the moving distance of the movable support plate 33 in the clamping adjustment chamber 7.Thereby, the moving distance or clamping force of the second clamping plate 11 is indirectly judged, and the detection data is fed back to the driving member 20 to control the action of the driving member 20, so as to ensure the stable clamping of the workpiece. No further details are given here. In addition, when clamping a workpiece of a larger size, the driving member 20 can be started to make the driving column 23 directly reach the inclined groove part. As the clamping movable seat 14 and the clamping movable seat 28 move, the inclined groove part directly drives the driving column 23 and drives the swing driving rod 14 to rotate, so that the adjusting inclined block 12 and the clamping roller 13 rotate synchronously, so that the clamping roller 13 contacts the other two side parts of the workpiece and clamps the workpiece. With the cooperation of the two clamping plates 10, the four side parts of the workpiece can be clamped, so as to ensure the stability of the workpiece during the entire processing operation. No further details are given here.

[0094] A lathe comprises a lathe body 1 and the lathe fixture described above, wherein the fixture support plate 2 is fixedly mounted on the bed of the lathe body 1. The outer shell of the lathe body 1 can adopt any existing lathe structure, and other accessories for processing can be installed at corresponding positions according to the positions of the fixture support plate 2 and the overall fixture. For example, if the fixture support plate 2 is horizontally mounted on the lathe body, the turning tool is installed above the fixture support plate 2, that is, above the workpiece processing base 3, so that the workpiece is processed from top to bottom by drilling or cutting, etc., which will not be described in detail here.
