Description

Technical Field

[0001] The invention relates to the technical field of axe production and processing, in particular to a grinding machine tool fixture for axe surface processing. Background Art

[0002] During the production process of axes, in order to improve the production quality of axes, production personnel will grind the axes through grinding machines. Grinding can effectively remove burrs and impurities on the surface of the axe, and ensure that the blade of the axe reaches the required angle and precision, thereby improving the cutting and felling efficiency when the axe is used. In order to ensure the grinding effect, people will fix the axe with a specific clamp.

[0003] Most of the clamps in the prior art use a two-sided clamping method to perform clamping and limiting operations. The two-sided clamping method can generally only form two symmetrical clamping points on the outer wall of the object. This method has a relatively stable clamping force when clamping regular objects such as rectangles, but cannot provide a stable and strong clamping effect when clamping irregular objects such as circles or ellipses. In real life, the shape of the axe head will be designed into different shapes according to usage requirements. Therefore, the outer surface contour of the axe is changeable, which may be a rectangle, or it may be an irregular shape such as an ellipse, shuttle (double-edged axe), etc., and the existing clamps cannot provide a stable and strong clamping and limiting effect for axes with special structures; at the same time, the existing clamps can only clamp one group of axes separately at a time, so the grinding machine can only grind one group of axes at a time, which leads to low grinding efficiency.

DETAILED DESCRIPTION

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Example 1 Reference Figure 1 to Figure 5 , which is the first embodiment of the present invention, comprises a grinding machine fixture for axe surface processing, comprising a base and a driving motor, and further comprising, The clamping unit 100 includes a limiting seat 101 fixedly connected to the top of the base, two groups of pushing parts 102 symmetrically arranged above the limiting seat 101, two groups of first clamping parts 103 slidably inserted inside each group of pushing parts 102, two groups of second clamping parts 104 slidably inserted inside each group of first clamping parts 103, abutting parts 105 slidably inserted inside each group of second clamping parts 104, and a driving screw 106 transversely arranged below the two groups of pushing parts 102, and both ends of the driving screw 106 are rotatably connected to both sides of the limiting seat 101; and, The driving unit 200 includes a connecting component 201 arranged in the limiting seat 101, and the connecting component 201 passes vertically from the bottom of the driving screw 106, a driving component 202 rotatably sleeved on one end of the connecting component 201, and the outer end side of the driving component 202 is meshed with the middle section of the driving screw 106, a limiting frame 203 sleeved on the driving component 202, and the lower part of the limiting frame 203 is fixedly connected to the base, an engaging component 204 is slidably sleeved on the connecting component 201, and the outer end of the engaging component 204 is clamped with the inner end of the driving component 202, and a supporting spring 205 sleeved on the other end of the connecting component 201, and one end of the supporting spring 205 abuts against the outer end of the engaging component 204.

[0027] During use, the driving motor drives the connecting component 201 to rotate the entire driving unit 200. The rotating driving unit 200 drives the driving screw 106 to rotate through the driving component 202. The driving screw 106 pushes the two groups of pushing components 102 to slide in a plane in relative directions above the limiting seat 101, and the axe to be clamped is placed between the two groups of pushing components 102. By controlling the rotation direction of the driving motor, the driving screw 106 can be controlled to drive the two groups of pushing components 102 to clamp inward or release outward at the same time, thereby achieving the purpose of clamping the axe or releasing the clamped axe.

[0028] Among them, combined Figure 1 There are three groups of clamping units 100, and the three groups of clamping units 100 are equally divided and fixed on the base. A group of driving units 200 is vertically arranged in the limiting seat 101 of each group of clamping units 100. The connecting parts 201 of the three groups of driving units 200 are vertically rotatably arranged inside the three groups of clamping units 100 in a head-to-tail manner, and the outermost ends of the three groups of connecting parts 201 connected head-to-tail are fixedly connected to the rotor shaft of the driving motor.

[0029] During use, the base is used to install and fix the clamping unit 100 and the driving unit 200, and the driving motor is used to provide power for the clamp to perform clamping work. The driving motor can drive the connecting component 201 to rotate through the rotor shaft, thereby driving the driving component 202 and the meshing component 204 on the connecting component 201 to rotate synchronously. The synchronously rotating driving component 202 can drive the clamping unit 100 to clamp or release by driving the driving screw 106 to rotate.

[0030] Example 2 Reference Figure 3-4, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: on the basis of having the function of clamping and fixing regular objects, it further adds the function of clamping and fixing special-shaped objects, and has good clamping performance and stronger stability, and can better meet the use requirements during axe grinding processing.

[0031] Compared with Example 1, further, combined with Figure 3 A limiting groove 101a is horizontally opened on the limiting seat 101, and the driving screw 106 is horizontally arranged in the limiting groove 101a. A driven gear 106a is fixedly arranged at the middle position of the driving screw 106, and the outer side of the driven gear 106a is meshed with the outer end side of the limiting frame 203.

[0032] Among them, combined Figure 4 The pushing component 102 includes a pushing plate 102a of a fan-shaped structure, two groups of first arc grooves 102b opened on the inner side of the pushing plate 102a, and the first clamping component 103 is slidably inserted in the first arc groove 102b, a first limiting slide plate 102c fixedly arranged on the inner wall of the first arc groove 102b, and a connecting ear 102d fixedly arranged on the bottom surface of the pushing plate 102a in a vertical direction, and the connecting ear 102d extends downward to the inside of the limiting groove 101a, and the driving screw 106 passes through the connecting ear 102d horizontally, and the two are threadedly connected.

[0033] During use, since the connecting ear 102d below the pushing plate 102a passes through the limiting groove 101a, the driving screw 106 will penetrate the connecting ear 102d horizontally. Therefore, the connecting ear 102d will be limited by the limiting groove 101a, and the pushing plate 102a fixedly connected thereto can only slide along the limiting groove 101a. The two groups of pushing components 102 are symmetrically arranged on both sides above the limiting seat 101, and the connecting ears 102d of the two groups of pushing components 102 are all threadedly connected to the driving screw 106. Therefore, when the driving screw 106 rotates, it will drive the connecting ears 102d on both sides through threaded engagement to drive the two groups of pushing components 102 to move in relative directions, thereby realizing the clamping or releasing action.

[0034] Among them, combined Figure 4 The first clamping component 103 includes a first parting module 103a of a fan-shaped structure, and the first parting module 103a is located in the first limiting slide 102c, two sets of second arc grooves 103b are opened on the inner side of the first parting module 103a, and the second clamping component 104 is slidably inserted in the second arc groove 103b, a second limiting slide 103c is fixedly arranged in the second arc groove 103b, and a first slot 103d is opened on the outer wall of the first parting module 103a, and the first limiting slide 102c is matched and inserted in the first slot 103d.

[0035] During use, the first parting module 103a can slide and displace along the inner wall of the first arc-shaped groove 102b under the limitation of the first limiting slide plate 102c through the cooperation of the first slot 103d and the first limiting slide plate 102c. When the inner side of the first clamping component 103 is subjected to actual external pressure, it can displace and slide along the arc angle of the first limiting slide plate 102c, so as to perform adaptive position adjustment. The adjusted first clamping component 103 will have an optimal point for abutting against an external object, which can provide a stable and powerful reverse force. The pushing component 102 includes two groups of first clamping components 103, so the two groups of first clamping components 103 can provide at least two stable abutment points.

[0036] Among them, combined Figure 4 The second clamping component 104 includes a second parting module 104a with a fan-shaped structure, and the second parting module 104a is located in the second limiting slide 103c, two sets of third arc grooves 104b are opened on the inner side of the second parting module 104a, and the abutment component 105 is slidably inserted in the third arc groove 104b, a third limiting slide 104c is fixedly arranged in the third arc groove 104b, and a second slot 104d is opened on the outer wall of the second parting module 104a, and the second limiting slide 103c is matched and inserted in the second slot 104d.

[0037] During use, the second clamping component 104 can also adjust its position on the side of the first clamping component 103 when subjected to external force, in the same principle as the position adjustment of the first clamping component 103 in the pushing component 102, so as to achieve the purpose of continuing to adjust the position on the basis of the position adjustment of the first clamping component 103, thereby further optimizing the point of contact with the external object. At the same time, each group of first clamping components 103 has two groups of second clamping components 104, so the two groups of first clamping components 103 have a total of four groups of second clamping components 104. The four groups of second clamping components 104 can make more optimal points of contact with external objects through their respective adjustment and conversion, and each contact point does not overlap with each other, so that the contact between the second clamping component 104 and the object will increase, thereby making the clamp fit more closely with the object when clamping.

[0038] Among them, combined Figure 4 The abutting component 105 includes an abutting block 105a located in the third arc groove 104b, and two groups of protrusions are arranged on the outer side of the abutting block 105a, and a third slot 105b is opened on the outer wall of the abutting block 105a, and the third limiting slide plate 104c is matched and inserted in the third slot 105b.

[0039] During use, the principle is the same as that of the second clamping component 104 adjusting its position in the first clamping component 103. The abutment component 105 can also be adjusted on the side of the second clamping component 104 when subjected to external force, thereby achieving the purpose of continuing to adjust the position on the basis of the first clamping component 103 and the second clamping component 104, thereby further optimizing the abutment point with the external object. There are eight groups of abutment components 105, which will further increase the contact area with the clamped object, thereby further making the clamp and the clamped object fit better and providing a stronger and more stable clamping performance.

[0040] In summary, when clamping the axe, multiple groups of non-overlapping clamping points can be formed through multiple position fine-tuning of the first clamping member 103, the second clamping member 104 and the abutting member 105, and the specific position of each group of clamping points is changed according to the shape of the clamped object. Therefore, these clamping points cooperate with each other to form different clamping shapes, thereby achieving the purpose of limited clamping of axes of different shapes (such as Figure 7 and Figure 8 As shown in the figure, multiple groups of non-overlapping points can increase the contact area between the clamp and the axe. Compared with the traditional two-point clamping, multi-directional clamping force is applied through multiple groups of clamping points to form a multi-directional and multi-angle clamping effect, which can greatly enhance the stability during clamping and provide a stable and powerful clamping limit effect.

[0041] The remaining structures are the same as those of Example 1.

[0042] Example 3 Reference Figures 5 to 8 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that the three groups of clamping units 100 are driven in stages to perform limit clamping operations in sequence, so that the same clamp can simultaneously perform limit clamping operations on axes of different numbers and sizes, thereby greatly improving the efficiency of the grinding work.

[0043] Compared with Example 2, further, combined with Figure 5 The connecting component 201 includes a driving shaft 201a whose end is fixedly connected to the rotor shaft of the driving motor, a limiting slide groove 201b provided on the driving shaft 201a, and a limiting plate 201c fixedly arranged on the driving shaft 201a, and the end of the supporting spring 205 abuts against the side of the limiting plate 201c.

[0044] During use, the three groups of connecting parts 201 are fixedly connected together, so the driving motor can synchronously drive the three groups of connecting parts 201 to rotate at the same time, and the limiting plate 201c is used to limit the support spring 205, so that the support spring 205 is located between the limiting plate 201c and the engaging part 204, so that the support spring 205 always applies outward elastic supporting force to both sides.

[0045] Among them, combined Figure 5 The driving component 202 includes a chuck 202a which is sleeved on one end of the driving shaft 201a, and one end of the chuck 202a is a staggered cam structure, a driving gear 202b is arranged on the outer end of the chuck 202a, and the driving gear 202b is meshed with the driven gear 106a, and a mounting groove 202c is fixedly arranged between the chuck 202a and the driving gear 202b, and the limiting frame 203 is sleeved and installed on the mounting groove 202c.

[0046] During use, combine Figure 5 and Figure 6 The driving component 202 is installed under the limiting seat 101 through the limiting frame 203, and will not rotate with the rotation of the driving shaft 201a, but the driving component 202 as a whole can rotate with the driving shaft 201a as the axis. The cam structure edge of the chuck 202a is a structure with a certain curvature. The driving component 202 can drive the driving screw 106 to rotate synchronously when rotating through the engagement of the driving gear 202b and the driven gear 106a, thereby driving the clamping unit 100 to clamp or move.

[0047] Among them, combined Figure 5 The engaging component 204 includes a sleeve 204a sleeved on the driving shaft 201a, an insert plate 204b arranged at the outer end of the sleeve 204a, and the outer end of the insert plate 204b is a cam structure matching the chuck 202a, and a latch tooth 204c fixedly arranged in the sleeve 204a in the vertical direction, and the latch tooth 204c is inserted in the limiting slide groove 201b.

[0048] During use, the sleeve 204a is elastically supported by the support spring 205 so that the tooth 204c at the outer end is always engaged with the side of the chuck 202a. The chuck 202a engaged with the tooth 204c temporarily connects the driving component 202 and the engaging component 204 as a whole, and the two can rotate synchronously. Because the plug plate 204b extends into the limiting slide groove 201b, the engaging component 204 is limited in the circumferential direction of the connecting component 201 and will rotate with the rotation of the connecting component 201, but the engaging component 204 can slide horizontally along the limiting slide groove 201b through the plug plate 204b.

[0049] In summary, combined Figure 2 and Figure 6 When multiple groups of axes with different specifications are synchronously clamped by three groups of clamping units 100, the driving motor drives the three groups of driving units 200 to move synchronously through the connecting component 201. When the connecting component 201 rotates, the connecting component 201 will drive the meshing component 204 to rotate synchronously. Due to the elastic support of the supporting spring 205, the clamping teeth 204c at the top of the meshing component 204 will be clamped together with the outer end of the chuck 202a. At this time, the meshing component 204 rotating with the connecting component 201 can synchronously drive the driving component 202 to rotate, and the rotating driving component 202 can rotate synchronously. The driving gear 202b is meshed with the driven gear 106a, driving the driving screw 106 to rotate, thereby driving the clamping unit 100 to perform a clamping operation. When one of the three groups of clamping units 100 is clamped in place, the driving screw 106 below the clamping unit 100 will be subject to the reverse force of the pushing component 102 and cannot rotate. At this time, the driving screw 106 will apply the reverse force to the driving component 202 through the driven gear 106a, thereby making the driving component 202 unable to rotate, but the meshing component 204 still rotates with the connecting component 201. At this time, the latching tooth 204c at the top of the meshing member 204 is continuously engaged with the chuck 202a. As the driving member 202 continues to rotate in a circular motion, the latching tooth 204c will eventually slide outward through the edge of the cam structure of the chuck 202a, converting the circumferential rotational force of the driving member 202 into a force that compresses the supporting spring 205 backward to contract, thereby causing the meshing member 204 to be misaligned with the driving member 202. At this time, the meshing member 204 will no longer be connected to the driving member 202, and will not affect the rotation of the connecting member 201 that is mutually limited with the driving member 202, and can rotate normally. The movable connecting component 201 will continue to drive the driving units 200 under the other two groups of clamping units 100 to continue the clamping work, and so on. After any one group of clamping units 100 is clamped in place, the driving unit 200 can continue to push the other two groups of clamping units 100 to clamp, so that the clamping operations of the three groups of clamping units 100 do not affect each other, and can be carried out simultaneously or stopped step by step, realizing a graded and segmented operation mode, and thus being able to achieve the function of simultaneously performing limit clamping operations on multiple groups of axes with different sizes and specifications, greatly improving work efficiency.

[0050] The remaining structure is the same as that of Example 2.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
