[0040] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0041] See also Figure 1 The present invention provides a quick clamping device 100, which includes a supporting assembly 10, a first-direction abutment block 20, a clamping assembly 30, a positioning assembly 40, and a pressing mechanism 50. The quick clamping device 100 is used to clamp and position a workpiece (not shown). The workpiece may be a mobile phone frame.

[0042] In order to facilitate understanding of the description, a three-dimensional coordinate system is established in some drawings, and the first direction is Figure 1 The X-axis direction is shown, and the second direction is Figure 1 The Y-axis direction shown, the third direction is Figure 1 The Z-axis direction is shown. Among them, the X-axis direction, the Y-axis direction and the Z-axis direction are perpendicular to each other.

[0043] See also Figure 1 、 Figure 2 and Figure 3The bearing assembly 10 includes a bearing seat 11, which has a boss 111. The first direction abutment block 20 is provided on the bearing seat 11 and is spaced apart from the boss 111. The clamping assembly 30 includes a first direction clamping block 31 and a first direction movable rod 32. The first direction clamping block 31 is provided on the bearing seat 11. One end of the first direction movable rod 32 is connected to the first direction clamping block 31, and the other end of the first direction movable rod 32 is movably provided in the bearing seat 11 along the first direction. The first direction movable rod 32 has a sliding groove 321. The positioning assembly 40 includes a second direction clamping block 41 and a second direction movable rod 42. The second direction clamping block 41, the first direction abutment block 20, the boss 111 and the first direction clamping block 31 enclose a mounting position 411 for the workpiece and clamp the workpiece. One end of the second direction movable rod 42 is connected to the second direction clamping block 41, and the other end of the second direction movable rod 42 is movably provided in the bearing seat 11 along the second direction to be slidably connected to the sliding groove 321. The pressing mechanism 50 includes a rotary pressing member 51, a pushing member 52 and a rotating assembly 53. The rotary pressing member 51 presses the workpiece to the mounting position 411 in the third direction. The pushing member 52 is sleeved on the rotating assembly 53 and is respectively arranged at both ends of the second direction movable rod 42 with the second direction clamping block 41. One end of the rotating assembly 53 is connected to the rotary pressing member 51, and the other end of the rotating assembly 53 is movably penetrated through the supporting seat 11 along the third direction. The rotating assembly 53 rotates and rises to drive the rotary pressing member 51 to rotate away from the workpiece, and drives the pushing member 52 to rotate and push the end of the second direction movable rod 42, so that the second direction movable rod 42 drives the second direction clamping block 41 away from the boss 111 to loosen the workpiece in the second direction, and causes the sliding groove 321 of the second direction movable rod 42 to slide sideways to push the first direction movable rod 32, so that the first direction movable rod 32 drives the first direction clamping block 31 away from the first direction abutment block 20 to loosen the workpiece in the second direction.

[0044] When clamping a workpiece, the above-mentioned quick clamping device 100 drives the first direction clamping block 31 to move close to the first direction abutment block 20 through the first direction movable rod 32, and drives the second direction clamping block 41 to move close to the boss 111 through the second direction movable rod 42. The workpiece in the mounting position 411 is clamped in the first and second directions, and the workpiece is pressed in the mounting position 411 in the third direction by rotating the clamping member 51, thereby clamping the workpiece to the mounting position 411 in the third direction, thereby improving the clamping efficiency. When the workpiece is to be disassembled, the rotating assembly 53 is raised to drive the rotating clamping member 51 to rotate away from the workpiece, and the pushing member 52 is driven to rotate and push the end of the second direction movable rod 42, so that the second direction movable rod 42 drives the second direction clamping block 41 away from the boss 111 to loosen the workpiece in the second direction, and the sliding groove 321 of the second direction movable rod 42 slides sideways to push the first direction movable rod 32, so that the first direction movable rod 32 drives the first direction clamping block 31 away from the first direction abutment block 20 to loosen the workpiece in the first direction, thereby achieving the simultaneous loosening of the workpiece in the first direction, the second direction and the third direction, thereby achieving rapid positioning and loosening of the workpiece, and improving the disassembly efficiency.

[0045] See also Figure 3 In some embodiments, a side wall of the sliding groove 321 has a conical inclined surface 3211, and the side of the second direction movable rod 42 has a side groove 421. The side groove 421 has a side push inclined surface 4211 that is slidably connected to the conical inclined surface 3211. The pushing member 52 rotates to push the end of the second direction movable rod 42, driving the side push inclined surface 4211 to slide against the conical inclined surface 3211 to push the first direction movable rod 32 in the first direction.

[0046] In this way, when placing the workpiece to be clamped and positioned or loosening the workpiece after positioning, the second direction movable rod 42 slides against the conical inclined surface 3211 through the side push inclined surface 4211 opened in the side groove 421, so that the second direction movable rod 42 moves closer to or away from the boss 111, and drives the first direction movable rod 32 to drive the first direction clamping block 31 to move closer to or away from the first direction abutment block 20. When positioning the workpiece, the side push inclined surface 4211 slides with the conical inclined surface 3211 to avoid interference between the second direction movable rod 42 and the first direction movable rod 32, thereby affecting the clamping positioning and disassembly operations of the second direction clamping block 41 and the first direction clamping block 31.

[0047] In some embodiments, the first-direction movable rod 32 defines a first movable hole 322, and the second-direction movable rod 42 defines a second movable hole 422. The quick clamping device 100 further includes a first fixing member 60, a first elastic member 70, a second fixing member 80, and a second elastic member 90. The first fixing member 60 is inserted into the bearing seat 11 and extends into the first movable hole 322. One end of the first elastic member 70 is connected to the first fixing member 60, and the other end of the first elastic member 70 is connected to a side wall of the first movable hole 322. The second fixing member 80 is inserted into the bearing seat 11 and extends into the second movable hole 422. One end of the second elastic member 90 is connected to the second fixing member 80, and the other end of the second elastic member 90 is connected to a side wall of the second movable hole 422. For example, the first elastic member 70 and the second elastic member 90 may be springs.

[0048] In this way, the first fixing member 60 extends into the first movable hole 322 and is connected to the first elastic member 70. When the workpiece is loosened and positioned, the first direction movable rod 32 drives the first direction clamping block 31 to loosen the workpiece, and compresses the first elastic member 70 to the first fixing member 60 through the side wall of the first movable hole 322. When clamping and positioning the workpiece, the compressed first elastic member 70 elastically opens and resets, so that the first direction movable rod 32 drives the first direction clamping block 31 to move close to the first direction abutment block 20, so as to realize the function of elastically clamping the workpiece in the first direction. In addition, the second fixing member 80 extends into the second movable hole 422 and is connected to the second elastic member 90. When the workpiece is loosened and positioned, the second direction movable rod 42 drives the second direction clamping block 41 to loosen the workpiece, and compresses the second elastic member 90 to the second fixing member 80 through the side wall of the second movable hole 422. When clamping and positioning the workpiece, the compressed second elastic member 90 elastically opens and resets, so that the second direction movable rod 42 drives the second direction clamping block 41 to move close to the boss 111, so as to realize the function of elastically clamping the workpiece in the second direction.

[0049] See also Figure 1 、 Figure 3 and Figure 4 In some embodiments, the boss 111 defines a plurality of fixing holes 1111. The quick clamping device 100 further includes a length adjustment rod 140 and a locking member 150. The length adjustment rod 140 defines a plurality of selection holes 141. One end of the length adjustment rod 140 is bent and connected to the first-direction abutment block 20. The other end of the length adjustment rod 140 is movably inserted through the boss 111 so that at least one selection hole 141 mates with the fixing hole 1111. The locking member 150 is inserted into the fixing hole 1111 and extends into at least one selection hole 141. For example, the locking member 150 may be a screw. The locking member 150 can be selectively inserted into one of the plurality of fixing holes 1111 and one of the plurality of selection holes 141 depending on the size of the workpiece.

[0050] In this way, by inserting the locking body 150 into the fixing hole 1111 and extending it into at least one selection hole 141, the length adjustment rod 140 and the boss 111 can be detachably connected, so that a split structure is formed between the length adjustment rod 140 and the first direction abutment block 20 connected to the length adjustment rod 140 and the boss 111. Therefore, according to the positioning requirements of workpieces of different sizes, the length of the length adjustment rod 140 inserted into the boss 111 can be adjusted to adjust the clamping distance between the first direction abutment block 20 and the first direction clamping block 31 in the first direction, thereby enabling the quick clamping device 100 to position workpieces of different sizes.

[0051] In some embodiments, the first direction movable rod 32 is detachably connected to the first direction clamping block 31, and the second direction movable rod 42 is detachably connected to the second direction clamping block 41. The first direction clamping block 31 and the second direction movable rod 42 of different lengths can be replaced according to the size of the workpiece to adjust the clamping distance between the first direction and the first direction abutment block 20, and the clamping distance between the second direction clamping block 41 and the boss 111 in the second direction, so that the quick clamping device 100 can position workpieces of different sizes and types.

[0052] See also Figure 1 and Figure 4 In some embodiments, the boss 111 has an extension portion 1112, which is suspended above the supporting seat 11 to form a movable gap 1113, and the curved connection between the length adjustment rod 140 and the first direction abutment block 20 moves in the movable gap 1113.

[0053] In this way, a movable gap 1113 is formed between the extension portion 1112 and the upper surface of the supporting seat 11, so that the curved connection between the length adjustment rod 140 and the first direction abutment block 20 is accommodated in the movable gap 1113, thereby making the supporting seat 11 and the first direction abutment block 20 reasonably arranged.

[0054] See also Figure 1 and Figure 4 In some embodiments, the support assembly 10 further includes a support base 12 and a base 13. The support base 12 supports the support base 11, the first-direction movable rod 32, and the second-direction movable rod 42. A recess 121 is defined on the side of the support base 12 facing away from the support base 11. The base 13 is fixedly mounted on the external platform. A protrusion 131 is defined on the side of the base 13 facing away from the external platform. The protrusion 131 engages and secures the recess 121.

[0055] In this way, the base 13 holds the fixed recess 121 through the protrusion 131 to support the support base 12 and the bearing base 11, so that the base 13 stably supports the support base 12 and the bearing base 11, thereby ensuring that the various components cooperate stably with each other.

[0056] In some embodiments, the support base 12 and the base 13 can also be connected by screws. Figure 2 and Figure 3 In some embodiments, a supporting groove 122 is defined on one side of the support base 12, and the rotating assembly 53 includes a rotating rod 531, a supporting sleeve 532, and a third elastic member 533. The rotating rod 531 is connected to the rotating pressing member 51, the pushing member 52 is sleeved on the rotating rod 531, and the supporting sleeve 532 is sleeved on the end of the rotating rod 531 away from the rotating pressing member 51. The third elastic member 533 is disposed in the supporting groove 122, with the ends of the third elastic member 533 elastically supporting the supporting sleeve 532 and the top wall of the supporting groove 122, respectively. For example, the third elastic member 533 may be a spring.

[0057] In this way, when the workpiece needs to be disassembled, the rotating rod 531 rises and rotates under the action of external force, so as to drive the supporting sleeve 532 to compress the third elastic member 533 to the top wall of the supporting groove 122, thereby realizing the function of loosening the workpiece in the third direction; when the workpiece needs to be pressed, the rotating rod 531 drives the rotating pressing member 51 to rotate and reset under the action of external force. When the external force is released, the compressed third elastic member 533 elastically opens and resets to drive the rotating pressing member 51 to press the workpiece to the installation position 411, thereby realizing the function of pressing the workpiece in the third direction.

[0058] See also Figure 2 and Figure 4 In some embodiments, the supporting seat 11 is further provided with a communicating limiting groove 112 and a clamping groove 113, and the rotary pressing member 51 includes a clamping portion 511 and a rotating portion 512 connected to the clamping portion 511, and the rotating portion 512 is connected to the rotating assembly 53. The rotating assembly 53 drives the clamping portion 511 to rise from the limiting groove 112 and rotate toward the clamping groove 113, so as to drive the clamping portion 511 to rise and rotate away from the workpiece.

[0059] In this way, the rotating pressing member 51 is clamped by the limiting groove 112 when the rotating pressing member 51 presses against the workpiece, so that the rotating pressing member 51 remains in a positioned state. The rotating pressing member 51 is clamped by the clamping groove 113 when the rotating pressing member 51 loosens the workpiece, so that the rotating pressing member 51 remains in a loose state. The rotating pressing member 51 is clamped in different states by the limiting groove 112 and the clamping groove 113, so as to prevent the rotating pressing member 51 from rotating when positioning the workpiece or loosening the workpiece.

[0060] See also Figure 3 In some embodiments, the push member 52 is a cam or an elliptical cylinder.

[0061] In this way, by setting the push member 52 as a cam or an elliptical cylinder, the push member 52 can be rotated under the drive of the rotating rod 531 to push the second direction movable rod 42 away from the boss 111, thereby achieving the function of pushing the second direction movable rod 42 to loosen the workpiece.

[0062] Among them, taking the push member 52 as an elliptical cylinder as an example, the side wall of the push member 52 is formed by two first push surfaces 521 and two second push surfaces 522. The two first push surfaces 521 and the two second push surfaces 522 are arranged on the outside of the push member 52 and alternately arranged along the circumference of the push member 52. The distance between the two first push surfaces 521 is greater than the distance between the two second push surfaces 522.

[0063] In this way, by setting the distance between the first pushing surface 521 and the center line L of the pushing member 52 to be greater than the distance between the second pushing surface 522 and the center line L of the pushing member 52, the first pushing surface 521 and the second pushing surface 522 alternately correspond to the second direction movable rod 42 during the rotation of the pushing member 52. In the process of switching from the second pushing surface 522 to the first pushing surface 521, the pushing member 52 stably pushes the second direction movable rod 42 to compress the second elastic member 90 along the second direction. In the process of switching from the first pushing surface 521 to the second pushing surface 522, the pushing member 52 stably loosens the second direction movable rod 42, thereby realizing the function of the pushing member 52 pushing the second direction movable rod 42 and loosening the second direction movable rod 42.

[0064] See also Figure 5 The embodiment of the present application further provides a processing device 200, comprising a quick clamping device 100 and a tool 201 disposed above the quick clamping device 100, wherein the tool 201 is used to process a workpiece. The tool 201 may be a milling cutter or the like.

[0065] The working process of the above-mentioned processing equipment 200 is roughly as follows:

[0066] First, the rotating pressing member 51 drives the rotating rod 531 to rotate and rise under the action of external force. Specifically, the rotating portion 512 rises from the limiting groove 112 and is rotated and clamped in the clamping groove 113. The rotating rod 531 compresses the third elastic member 533 to the top wall of the abutting groove 122 through the abutting sleeve 532. The pushing member 52 pushes the second direction movable rod 42 under the drive of the rotating rod 531. The second direction movable rod 42 drives the second direction clamping block 41 away from the boss 111 and compresses the second elastic member 90 to the second fixing member 80. At the same time, the sliding groove 321 of the second direction movable rod 42 pushes the first direction movable rod 32 sideways, so that the first direction movable rod 32 drives the first direction clamping block 31 to move away from the first direction abutting block 20 and compresses the first elastic member 70 to the first fixing member 60, so that the mounting position 411 of the supporting seat 11 can be placed in the workpiece;

[0067] When the second spring 533 is in the state of being pressed, the second spring 533 is released from the state of being pressed, and the second spring 533 is released from the state of being pressed, so that the workpiece 51 is prevented from being moved to the first position on the support 11 by the spring 511.

[0068] Finally, after the tool 201 processes the positioned workpiece, the rotary pressing member 51 drives the rotary rod 531 to rotate and rise under the action of external force. Specifically, the rotating portion 512 rises from the limiting groove 112 and is rotated and clamped in the clamping groove 113. The rotary pressing member 51 loosens the processed workpiece in the third direction. The rotary rod 531 compresses the third elastic member 533 to the top wall of the holding groove 122 through the holding sleeve 532. The pushing member 52 pushes the second direction movable rod 42 under the drive of the rotating rod 531. The second direction movable rod 42 drives the second direction movable rod 42 to move. The clamping block 41 is moved away from the boss 111, and the second elastic member 90 is compressed to the second fixing member 80. At the same time, the sliding groove 321 of the second direction movable rod 42 pushes the first movable rod sideways, so that the first direction movable rod 32 drives the first direction clamping block 31 to move away from the first direction abutment block 20, and compresses the first elastic member 70 to the first fixing member 60, thereby simultaneously releasing the workpiece in the first direction, the second direction and the third direction, thereby quickly loosening the workpiece, facilitating repeated positioning of the workpiece, and further improving the workpiece disassembly efficiency.
