[0036] The leaf spring seat fixture plays an important role in leaf spring seat processing. In the related art, after the leaf spring seat is clamped by the leaf spring seat fixture for milling, the leaf spring seat fixture needs to be replaced and clamped by a new leaf spring seat fixture for drilling, which reduces the processing efficiency of the leaf spring seat.

[0037] To this end, an embodiment of the present invention provides a leaf spring seat clamp 1000, specifically referring to the accompanying drawings of the specification. Figures 1 to 6 shown.

[0038] Reference Figure 1 and Figure 2 As shown, a leaf spring seat clamp 1000 according to an embodiment of the present invention includes a base 100, a support plate 200, a support 300, a first locking mechanism 400, a second locking mechanism 500 and a third locking mechanism 600. Figure 1 and Figure 2As shown, the base 100 includes a bottom plate 110 and a connecting plate 120. The connecting plate 120 is connected to the bottom plate 110. It should be noted that the connecting plate 120 can be connected to the bottom plate 110 by welding, threaded connection, etc., or can be integrally formed with the bottom plate 110. The support plate 200 is used to place the leaf spring seat 2000, that is, the support plate 200 plays the role of supporting the leaf spring seat 2000. It should be noted that the support plate 200 is connected to the connecting plate 120 and is spaced apart from the bottom plate 110. It should be noted that the support plate 200 can be connected to the connecting plate 120 by threaded connection, etc. The support 300 is connected to the connecting plate 120 and is spaced apart from the support plate 200. It should be noted that the support 300 can be connected to the connecting plate 120 by threaded connection, etc. It should be noted that the support 300 is located above the support plate 200. In addition, the support 300 is provided with a support leg 310 , and the support leg 310 is located on a side of the support 300 facing the support plate 200 .

[0039] Reference Figure 1 As shown, the first locking mechanism 400 is fixed to the side of the support 300 facing away from the support plate 200 and is located at the end of the support 300 away from the connecting plate 120. It should be noted that the first locking mechanism 400 can lock the end of the leaf spring seat 2000 away from the connecting plate 120, thereby locking the leaf spring seat 2000 in the left-right direction. A second locking mechanism 500 is mounted on the support 300. It should be noted that the second locking mechanism 500 can lock the front and rear inner walls of the leaf spring seat 2000, thereby locking the leaf spring seat 2000 in the front-to-back direction. It should be noted that two second locking mechanisms 500 can be provided, distributed along the left-to-right direction of the support 300, to better lock the leaf spring seat 2000 in the front-to-back direction. A third locking mechanism 600 is mounted on the base plate 110 and extends through the support plate 200. It should be noted that the third locking mechanism 600 can lift the leaf spring seat 2000 until the leaf spring seat 2000 abuts against the support leg 310 , thereby locking the leaf spring seat 2000 in the up-down direction.

[0040] It is understandable that the leaf spring seat fixture 1000 can completely lock the leaf spring seat 2000, limiting six degrees of freedom. The leaf spring seat 2000 can be milled and drilled without replacing the leaf spring seat fixture 1000, thereby improving the processing efficiency of the leaf spring seat 2000.

[0041] Reference Figure 3As shown, a leaf spring seat clamp 1000 according to an embodiment of the present invention, the first locking mechanism 400 includes a base 410, a positioning block 420, a first movable member 430, a first threaded connector 440 and a first elastic member 450. Among them, the base 410 is fixedly mounted on the support 300, and the base 410 is provided with a mounting hole 411. It should be noted that the base 410 can be connected to the support 300 by means of a threaded connection or the like. The positioning block 420 is fixedly mounted on the base 410. It should be noted that the positioning block 420 can be connected to the base 410 by means of a threaded connection or the like. The first movable member 430 is movably mounted on the base 410 in the left and right directions. Specifically, the first movable member 430 is sleeved on the first threaded connector 440, and is at least partially located in the mounting hole 411. It should be noted that the first movable member 430 is provided with a hook portion 431. When the hook portion 431 moves toward the positioning block 420, the end of the leaf spring seat 2000 away from the connecting plate 120 is clamped between the positioning block 420 and the hook portion 431. The first threaded connector 440 is provided through the mounting hole 411 and is threadedly connected to the base 410. It should be noted that the first threaded connector 440 is capable of driving the hook portion 431 to move toward the positioning block 420. In one embodiment, the first threaded connector 440 includes a first bolt 441 and a first nut 442. One end of the first bolt 441 is threadedly connected to the base 410, and the other end is connected to the first nut 442. At this time, the first movable member 430 is located between the bottom wall of the mounting hole 411 and the first nut 442. When the first nut 442 rotates and moves on the first bolt 441 toward the positioning block 420, it can drive the hook portion 431 to move toward the positioning block 420.

[0042] Continue to refer to Figure 3 Shown, it should be noted that the first elastic member 450 is located in the mounting hole 411, and is between the first mobile member 430 and the mounting hole 411 inwalls.It should be noted that the first elastic member 450 can drive the hook portion 431 to move in the direction away from the positioning block 420.Particularly, when the leaf spring seat 2000 was clamped between the positioning block 420 and the hook portion 431 away from an end of the connecting plate 120, the first elastic member 450 was clamped by the first mobile member 430 and the mounting hole 411 inwalls, so that its generation was applied to the elastic force of the first mobile member 430 and the mounting hole 411 inwalls, allowing the first mobile member 430 to produce a trend away from the mounting hole 411 inwalls.If the first nut 442 rotates now, and on the first bolt 441, moves in the direction away from the positioning block 420, then the first mobile member 430 can move in the direction away from the positioning block 420 under the effect of the first elastic member 450, thereby realizing the automatic return of the first mobile member 430.

[0043] Reference Figure 4 and Figure 5As shown, a leaf spring seat clamp 1000 according to an embodiment of the present invention, the second locking mechanism 500 includes a second moving member 510, a third moving member 520 and a fourth moving member 530. The second moving member 510 is movably installed on the support 300 in the up and down directions, the third moving member 520 is movably provided in the support 300 and is located on the front side of the second moving member 510, and the fourth moving member 530 is movably provided in the support 300 and is located on the rear side of the second moving member 510. When the second moving member 510 moves downward, the second moving member 510 can drive the third moving member 520 to abut against the front end inner wall of the leaf spring seat 2000, and can drive the fourth moving member 530 to abut against the rear end inner wall of the leaf spring seat 2000.

[0044] Continue to refer to Figure 4 and Figure 5 Shown, it should be noted that, the second locking mechanism 500 also comprises the second bolt 561 and the second nut 562, and the second mobile member 510 is movably sleeved on the second bolt 561.One end of the second bolt 561 is threadedly connected with the support 300, and the other end is threadedly connected with the second nut 562.It is understandable that the second mobile member 510 is positioned between the junction of the second bolt 561 and the support 300 and the second nut 562.When the second nut 562 rotates, and moves downward on the second bolt 561, can drive the second mobile member 510 to move downward.

[0045] Continue to refer to Figure 4 and Figure 5 Shown, in one embodiment, the second moving member 510 has the first wedge surface 511 and the second wedge surface 512, the 3rd moving member 520 has the 3rd wedge surface 521, the 3rd wedge surface 521 abuts with the first wedge surface 511, and the 4th moving member 530 has the 4th wedge surface 531, and the 4th wedge surface 531 abuts with the second wedge surface 512. In one embodiment, the lower end of the second moving member 510 is truncated cone-shaped, and the first wedge surface 511 and the second wedge surface 512 are actually a face, namely are truncated cone sidewalls. It is understandable that when the second moving member 510 moves downward, the first wedge surface 511 and the second wedge surface 512 also move downward.Wherein, because the first wedge surface 511 abuts with the 3rd wedge surface 521, the 3rd wedge surface 521 can translate, so that the 3rd moving member 520 moves and abuts against the front end inner wall of the leaf spring seat 2000. Since the second wedge surface 512 abuts against the fourth wedge surface 531 , the fourth wedge surface 531 moves horizontally, causing the fourth moving member 530 to move and abut against the rear end inner wall of the leaf spring seat 2000 .

[0046] Continue to refer to Figure 4 and Figure 5As shown, it should be noted that the outer wall of the support 300 is provided with a first stop cover 320 and a second stop cover 330, one end of the third moving member 520 away from the third wedge surface 521 is penetrated by the first stop cover 320, and one end of the fourth moving member 530 away from the fourth wedge surface 531 is penetrated by the second stop cover 330, the third moving member 520 is provided with a first step 522 along its axial direction, and the fourth moving member 530 is provided with a second step 532 along its axial direction, and the second locking mechanism 500 further includes a second elastic member 540 and a third elastic member 550, the second elastic member 540 is provided between the first stop cover 320 and the first step 522, and the third elastic member 550 is provided between the second stop cover 330 and the second step 532. It is understandable that when the second moving member 510 moves downward, the second elastic member 540 is pressed between the first stop cover 320 and the first step 522, and the third elastic member 550 is pressed between the second stop cover 330 and the second step 532.

[0047] Need to prove, if the second nut 562 rotates, and moves upward on the second bolt 561, then the force that the first wedge surface 511 pairs of 3rd wedge surfaces 521 apply reduces, and the force that the second wedge surface 512 pairs of 4th wedge surfaces 531 apply reduces.Then the second elastic member 540 promotes the 3rd moving member 520 to move and break away from the front end inner wall of leaf spring seat 2000, and the 3rd elastic member 550 promotes the 4th moving member 530 to move and break away from the rear end inner wall of leaf spring seat 2000.Again because the 3rd wedge surface 521 abuts with the first wedge surface 511, and the 4th wedge surface 531 abuts with the second wedge surface 512, so the 3rd moving member 520 and the 4th moving member 530 can apply upward force to the second moving member 510 jointly, so that the second moving member 510 moves upward, thereby realize the automatic return of the second moving member 510.

[0048] Reference Figure 6 Shown, the leaf spring seat fixture 1000 of one embodiment of the present invention, the 3rd locking mechanism 600 comprises a driving mechanism 610 and the 5th mobile member 620.Wherein, the 5th mobile member 620 is arranged at supporting plate 200, and the driving mechanism 610 is installed on base plate 110, and is positioned at the below of supporting plate 200.In addition, the driving mechanism 610 is connected with the 5th mobile member 620, and can drive the 5th mobile member 620 to move up and down.It should be noted that, when the driving mechanism 610 drives the 5th mobile member 620 to move upwards, the 5th mobile member 620 upwards lifts the leaf spring seat 2000 until the leaf spring seat 2000 abuts against supporting leg 310.

[0049] Reference Figure 6As shown, it should be noted that the driving mechanism 610 includes a screw rod 611 and a wedge block 612 threadedly connected to the screw rod 611. It should be noted that the wedge block 612 has a fifth wedge surface 6121, and the lower end of the fifth movable member 620 is provided with a sixth wedge surface 621, and the fifth wedge surface 6121 is matched with the sixth wedge surface 621. It is understood that when the user drives the screw rod 611 to rotate, the wedge block 612 moves along the screw rod 611. Since the fifth wedge surface 6121 is matched with the sixth wedge surface 621, the fifth movable member 620 is exerted with an upward force by the wedge block 612, thereby moving upward to push up the leaf spring seat 2000.

[0050] Continue to refer to Figure 6 As shown, in one embodiment, the screw rod 611 includes a left thread portion 6111 and a right thread portion 6112, two wedge blocks 612 are provided, and two fifth moving members 620 are provided, wherein one wedge block 612 is threadedly connected to the left thread portion 6111 and cooperates with one of the fifth moving members 620, and the other wedge block 612 is threadedly connected to the right thread portion 6112 and cooperates with the other fifth moving member 620. It can be understood that through the above arrangement, the leaf spring seat 2000 can be better lifted.

[0051] Continue to refer to Figure 6 As shown, it should be noted that the screw rod 611 also includes a limiting portion 6113 connected between the left wire portion 6111 and the right wire portion 6112, and the limiting portion 6113 is provided with a first limiting protrusion 6001 and a second limiting protrusion 6002 along the axial direction of the screw rod 611, and the first limiting protrusion 6001 and the second limiting protrusion 6002 are arranged at intervals, and the base plate 110 or the supporting plate 200 is provided with a limiting column 210, and the limiting column 210 is arranged between the first limiting protrusion 6001 and the second limiting protrusion 6002. It should be noted that there is a gap between the limiting column 210 and the first limiting protrusion 6001, and there is also a gap between the limiting column 210 and the second limiting protrusion 6002, so that the screw rod 611 can move left and right within a certain range, and the two fifth moving members 620 can fluctuate up and down within a certain height range, thereby reducing the impact of the dimensional error of the leaf spring seat 2000.

[0052] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
