[0046] Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0047] Please refer to Figures 1-3. A cold-pressing tool mounting machine according to an embodiment of this application includes: a movable upper plate 1, a fixed lower plate 2, a driving device 3, an upper clamping unit 4, and a lower clamping unit 5.

[0048] The movable upper plate 1 has a first mounting groove 11 with a front opening. Referring to Figure 5, the first mounting groove 11 is arranged so that the movable upper plate 1 is U-shaped.

[0049] The fixed lower plate 2 is located below the movable upper plate 1 and has a second mounting groove 21 with a front opening. The first mounting groove 11 and the second mounting groove 21 are arranged vertically and vertically respectively.

[0050] The second mounting slot 21 is designed so that the fixed lower plate 2 is also U-shaped, and the fixed lower plate 2 and the movable upper plate 1 are slidably connected to each other in the vertical direction.

[0051] The driving device 3 drives the movable upper plate 1 to move vertically relative to the fixed lower plate 2 to move closer to or further away from the fixed lower plate 2.

[0052] In this embodiment, the driving device 3 is a cylinder or a hydraulic cylinder. The movable end of the driving device 3 is connected to the movable upper plate 1. When the movable upper plate 1 is driven to move up and down, the movable upper plate 1 and the fixed lower plate 2 can be closed or a gap can be formed between them.

[0053] The upper clamping unit 4 includes a first pad 41 and a second pad 42 for clamping the collet 9. The first pad 41 and the second pad 42 are disposed in the first mounting groove 11, with the first pad 41 disposed at the front opening of the first mounting groove 11. A pivot shaft 40 is provided on one side of the front opening of the first mounting groove 11. The first pad 41 is sleeved on the pivot shaft 40, and the first pad 41 can pivot around the pivot shaft 40 to connect or separate from the second pad 42, such that the first pad 41 pivots horizontally to the open position to separate from the second pad 42, or pivots horizontally to the closed position to connect with the second pad 42.

[0054] Referring to Figures 2-4 and 9-10, the first gasket 41 and the second gasket 42 are arranged one behind the other. Both the first gasket 41 and the second gasket 42 have semi-grooves for engaging with the collet 9. The first gasket 41 has a first clamping flange 44 protruding horizontally at the inner edge of its semi-groove, and the second gasket 42 has a second clamping flange 43 protruding horizontally at the inner edge of its semi-groove. When the first gasket 41 and the second gasket 42 are closed, the two semi-grooves close together, and the first clamping flange 44 and the second clamping flange 43 form an upper clamping portion 411 for clamping the collet 9. When the first gasket 41 is pivoted forward to the open position, the collet 9 can be exposed.

[0055] The lower clamping unit 5 includes a third washer 51 and a fourth washer 52 for clamping the tool holder 10. The third washer 51 and the fourth washer 52 are mounted in the second mounting groove 21, with the third washer 51 positioned at the front opening of the second mounting groove 21. The first washer 41 and the third washer 51 are slidably connected relative to each other in the vertical direction, and the second washer 42 and the fourth washer 52 are also slidably connected relative to each other in the vertical direction. Thus, when the movable upper plate 1 moves closer to or away from the fixed lower plate 2, the first washer 41 and the second washer 42 can move synchronously to move closer to or away from the third washer 51 and the fourth washer 52. The third washer 51 can pivot in the same pivot direction as the first washer 41 to connect or disconnect with the fourth washer 52, such that the third washer 51 pivots horizontally to the open position to disconnect from the fourth washer 52, or pivots horizontally to the closed position to connect with the fourth washer 52.

[0056] The third washer 51 and the fourth washer 52 are arranged correspondingly front and rear, and the first washer 41 and the third washer 51 are vertically aligned, as are the second washer 42 and the fourth washer 52. Similar to the upper clamping unit 4, the third washer 51 and the fourth washer 52 also have semi-grooves for engaging with the tool holder 10. The third washer 51 has a third clamping flange 54 protruding horizontally at the inner edge of its semi-groove, and the fourth washer 52 has a fourth clamping flange 53 protruding horizontally at the inner edge of its semi-groove. When the third washer 51 and the fourth washer 52 are closed, the two semi-grooves close together, and the third clamping flange 54 and the fourth clamping flange 53 form a lower clamping portion 511 that can clamp the tool holder 10. When the third washer 51 is pivoted forward to the open position, the tool holder 10 can be exposed.

[0057] The working process of the cold-pressed tool mounting machine in this application is as follows.

[0058] Please refer to Figure 4, which shows a schematic diagram of the cold-press tool mounting machine according to an embodiment of this application when the collet 9 is installed onto the tool holder 10. When it is necessary to install the collet 9 onto the tool holder 10, the collet 9 is first placed on the tool holder 10, and then the tool holder 10 is placed on the fourth clamping flange 53 of the fourth pad 52. At this time, the second clamping flange 43 of the second pad 42 is located above the collet 9, as shown in Figure 4. Pushing the first pad 41 can pivot it about the pivot axis 40 toward the second pad 42. In this example, it can be configured such that the third pad 51 rotates synchronously when the first pad 41 rotates. Thus, when the first pad 41 is in the closed position connected to the second pad 42, the third pad 51 is in the closed position connected to the fourth pad 52. At this time, the positions of the collet 9 and the tool holder 10 relative to each other are fixed. The driving device 3 drives the movable upper plate 1 to move downwards. The movable upper plate 1 drives the upper clamping unit 4 to move downwards and approach the fixed lower plate 2. The upper clamping parts 411 of the first pad 41 and the second pad 42 press down on the collet 9 until the collet 9 and the tool holder 10 are assembled together. For clarity, the first pad 41 and the third pad 51 are not shown in Figure 4.

[0059] Please refer to Figure 3, which shows a schematic diagram of the cold-press tool mounting machine of this application when removing the collet 9 from the tool holder 10. When it is necessary to remove the collet 9 from the tool holder 10, the tool holder 10 equipped with the collet 9 is first mounted on the second clamping flange 43 of the corresponding second pad 42 and the fourth clamping flange 53 of the fourth pad 52. At this time, the upper end of the collet 9 is located above the second clamping flange 43, as shown in Figure 3. Then, the first pad 41 and the third pad 51 can be rotated to the closed position. For clarity, the first pad 41 and the third pad 51 are not shown in Figure 3. Then, the drive device 3 drives the movable upper plate 1 to move upward away from the fixed lower plate 2. Since the upper end of the collet 9 is mounted above the upper clamping portion 411 formed by the first pad 41 and the second pad 42, when the movable upper plate 1 moves upward, the fixed lower plate 2 remains stationary, and the collet 9 is clamped by the upper clamping unit and moves upward, and is removed from the tool holder 10.

[0060] The third clamping flange 54 of the third washer 51 and the fourth clamping flange 53 of the fourth washer 52 are provided with annular protrusions, and corresponding annular grooves are provided on the tool holder 10. The protrusions are inserted into the grooves to fix the tool holder 10.

[0061] The first clamping flange 44 of the first gasket 41 and the second clamping flange 43 of the second gasket 42 are also provided with annular protrusions. The upper end of the collet 9 is provided with annular protrusions. The protrusions of the collet 9 are located above the protrusions, which can realize the clamping of the collet 9. Alternatively, the protrusions of the collet 9 are located below the protrusions. When the movable upper plate moves down, the protrusions and protrusions come into contact and can squeeze the protrusions.

[0062] The locking unit 6 is mounted on the fixed lower plate 2. The locking unit 6 can abut against the third washer 51 to lock the third washer 51.

[0063] The locking unit 6 can lock the third washer 51, thereby fixing the position of the tool holder 10. The third washer 51 is slidably connected to the first washer 41, so the position of the first washer 41 is also locked, and the position of the collet 9 is also fixed, thereby ensuring the assembly accuracy of the tool holder 10 and the collet 9.

[0064] The locking unit 6 is mounted on the fixed lower plate 2. When the driving device 3 drives the movable upper plate 1, the locking unit 6 will not move with the movable upper plate 1, thereby reducing the load on the driving device 3 and providing a better locking effect. Moreover, the closing structure of the gasket in this solution is simple, and the locking structure and the closing of the gasket do not interfere with each other.

[0065] The locking unit 6 is located on one side of the third gasket 51, which facilitates the arrangement of the locking unit 6 and makes it convenient for staff to operate the locking unit 6.

[0066] In some embodiments, referring to Figures 7 and 8, the locking unit 6 includes a locking switch 61, a connecting rod 62, and a limiting plate 63. The limiting plate 63 is slidably connected to the fixed lower plate 2. The two ends of the connecting rod 62 are respectively connected to the locking switch 61 and the limiting plate 63. When the locking switch 61 is rotated, the connecting rod 62 rotates and drives the limiting plate 63 to move closer to or further away from the third pad 51, so that the limiting plate 63 abuts against or separates from the third pad 51.

[0067] In this embodiment, the locking switch 61 is in the shape of a pull rod. When the locking switch 61 is rotated, it drives the connecting rod 62 to rotate. The rotation of the connecting rod 62 causes a change in position, which drives the limiting plate 63 to move closer to or further away from the third washer 51, that is, to move horizontally in this embodiment. Depending on the rotation direction of the locking switch 61, the limiting plate 63 can either press against the third washer 51 to lock the third washer 51, or retract and no longer press against the third washer 51 to unlock the third washer 51.

[0068] The cold pressing tool loading machine also includes a fixed stop 7, and a limiting plate 63 is slidably connected to the fixed lower plate 2 through the fixed stop 7.

[0069] In this embodiment, the locking unit 6 is disposed on the front side of the fixed lower plate 2, near the third gasket 51 and away from the fourth gasket 52, at the end near the third gasket 51 opposite to its pivot axis 40. This allows the limiting plate 63 to easily abut against the third gasket 51 and also facilitates the operation of the locking switch 61.

[0070] In this embodiment, the fixed block 7 is plate-shaped, the locking switch 61 is located on the front side of the fixed block 7, the limiting plate 63 and the connecting rod 62 are located on the rear side of the fixed block 7, and the fixed block 7 blocks the connecting rod 62 and at least a portion of the limiting plate 63.

[0071] The rear side of the fixed block 7 is provided with a first limiting groove 71 for accommodating the limiting plate 63 and a second limiting groove 72 for accommodating the connecting rod 62, and the first limiting groove 71 and the second limiting groove 72 are connected to each other.

[0072] Under the limitation of the first limiting groove 71, the limiting plate 63 can move within the first limiting groove 71, that is, the limiting plate 63 moves in the horizontal direction. In this embodiment, the first limiting groove 71 is a strip extending perpendicular to the axial direction of the tool holder 10.

[0073] The connecting rod 62 rotates in the second limiting groove 72, and the limiting plate 63 moves in the first limiting groove 71 under the drive of the connecting rod 62. In this embodiment, the second limiting groove 72 is fan-shaped.

[0074] Referring to Figure 6, in some embodiments, a third limiting groove 511 is provided on the side of the third gasket 51 near the limiting plate 63. The third limiting groove 511 is in communication with the first limiting groove 71. The limiting plate 63 can extend into the third limiting groove 511 and abut against the third gasket 51.

[0075] When the third gasket 51 is closed on the fourth gasket 52, one end of the limiting plate 63 is inserted into the third limiting groove 511 to lock the third gasket 51. This setting allows the third gasket 51 to be locked.

[0076] In some embodiments, the locking switch 61 is located on the front side of the fixed block 7, and the fixed block 7 is provided with a connector 73 that passes through it. The locking switch 61 is connected to the connecting rod 62 through the connector 73.

[0077] One end of the connector 73 is connected to the locking switch 61, and the other end is connected to the connecting rod 62. The connector 73 allows the locking switch 61 and the connecting rod 62 to be connected, and also allows the locking switch 61 and the connecting rod 62 to be located on both sides of the fixed stop 7.

[0078] In some embodiments, the connecting rod 62 is provided with a limiting hole 621 extending along the extension direction of the connecting rod 62, and the limiting plate 63 is provided with a fastener 631, and the fastener 631 is movably disposed in the limiting hole 621 to form a movable connection between the connecting rod 62 and the limiting plate 63.

[0079] The connecting rod 62 drives the limiting plate 63 to move, which converts the rotation of the connecting rod 62 into the linear motion of the limiting plate 63. The limiting hole 621 is strip-shaped. When the connecting rod 62 rotates, the fastener 631 moves in the limiting hole 621, guiding the limiting plate 63 to move in the first limiting groove 71.

[0080] A handle 512 is provided on the front side of the third gasket 51, and the handle 512 is located on the side of the third gasket 51 near the locking unit 6.

[0081] The handle 512 allows staff to easily control the opening and closing of the third pad 51 on the fourth pad 52.

[0082] The cold-press tool mounting machine also includes a transparent protective plate 8, which is located on the front side of the third pad 51. The transparent protective plate 8 can cover the upper clamping unit 4 and the lower clamping unit 5, thereby protecting the upper clamping unit 4 and the lower clamping unit 5 from external interference during operation.

[0083] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
