Description
Technical Field
[0001] This invention relates to the field of workpiece positioning, and more particularly to a workpiece processing equipment. Background Technology
[0002] Currently, a positioning mechanism is generally required to locate the workpiece before processing. This positioning mechanism has a gantry structure and is located above the positioning fixture that supports the workpiece. This type of positioning mechanism is prone to interference with other processing mechanisms, which can complicate the structure of the processing mechanism or even prevent the workpiece from being processed. In addition, the position of this positioning mechanism is fixed and cannot move with the positioning fixture, so it cannot adapt to changes in processing requirements.
[0003] Therefore, there is an urgent need for a workpiece processing device that allows the positioning fixture and the workpiece positioning mechanism to move synchronously to the processing position to overcome the above-mentioned defects. Summary of the Invention
[0004] The purpose of this invention is to provide a workpiece processing device that allows the positioning fixture and the workpiece positioning mechanism to move synchronously to the processing position.
[0005] To achieve the above objectives, the workpiece processing equipment of the present invention includes a positioning fixture for carrying the workpiece and a workpiece positioning mechanism. The positioning fixture and the workpiece positioning mechanism are each arranged in a movable manner. The positioning fixture is displaced between a first position and a second position. When the positioning fixture is in the first position, the workpiece positioning mechanism selectively docks with the positioning fixture and presses the workpiece. Then, the workpiece positioning mechanism and the positioning fixture move synchronously from the first position to the second position.
[0006] Preferably, the workpiece positioning mechanism and the positioning fixture are arranged to slide in the same direction.
[0007] Preferably, the workpiece positioning mechanism is located on one side of the positioning fixture, and the workpiece positioning mechanism is a cantilever structure.

[0012] Preferably, a plurality of pressing heads are installed on the pressing structure, the pressing heads are installed at the free end of the pressing structure, and the alignment connector is installed at the other end of the pressing structure away from its free end, with the pressing heads and the alignment connector located on the same side of the pressing structure.
[0013] Preferably, the workpiece positioning mechanism further includes an action driver and a displacement mounting bracket. The action driver is mounted on the displacement mounting bracket, and the pressing structure is slidably mounted on the displacement mounting bracket. The pressing structure is mounted on the output end of the action driver, and the action driver drives the pressing structure to slide between the initial position and the operating position.
[0014] Preferably, the workpiece positioning mechanism is blocked when it moves to the second position, so that the positioning fixture and the workpiece positioning mechanism stop at the second position at the same time.
[0015] Preferably, the workpiece positioning mechanism is arranged in a linear sliding manner between the first position and the second position.
[0016] Preferably, the workpiece processing equipment of the present invention further includes a slide rail structure and a displacement driver. The slide rail structure extends along the sliding direction of the workpiece positioning mechanism.

The displacement driver drives the workpiece positioning mechanism to slide on the slide rail structure.
[0017] Preferably, a blocking structure is installed at the second position. When the workpiece positioning mechanism moves to the second position, the blocking structure applies a force to the workpiece positioning mechanism. The direction of the force is opposite to the direction of movement of the workpiece positioning mechanism.

[0019] Preferably, the workpiece processing equipment of the present invention further includes a fixture driver, wherein a positioning fixture is mounted on the output end of the fixture driver, and the fixture driver drives the positioning fixture to move between a first position and a second position.
[0020] Compared with the prior art, the workpiece processing equipment of the present invention includes a positioning fixture for supporting the workpiece and a workpiece positioning mechanism. The positioning fixture and the workpiece positioning mechanism are each arranged in a movable manner, with the positioning fixture shifting between a first position and a second position. When the positioning fixture is in the first position, the workpiece positioning mechanism selectively engages with the positioning fixture and clamps the workpiece, then the workpiece positioning mechanism and the positioning fixture move synchronously from the first position to the second position. When the workpiece positioning mechanism and the positioning fixture are engaged, they are accurately aligned.

[0026] To illustrate the technical content and structural features of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.
[0027] like Figures 1 to 5As shown, the workpiece processing equipment 100 of the present invention includes a positioning fixture 10 for carrying the workpiece and a workpiece positioning mechanism 20. The positioning fixture 10 and the workpiece positioning mechanism 20 are each arranged in a movable manner, with the positioning fixture 10 shifting between a first position and a second position. When the positioning fixture 10 is in the first position, the workpiece positioning mechanism 20 selectively engages with the positioning fixture 10 and presses the workpiece, then the workpiece positioning mechanism 20 and the positioning fixture 10 move synchronously from the first position to the second position. When the workpiece positioning mechanism 20 is engaged with the positioning fixture 10, the workpiece positioning mechanism 20 and the positioning fixture 10 are accurately aligned. Therefore, when the positioning fixture 10 is in the first position, the workpiece positioning mechanism 20 corresponds to the first position, and the workpiece positioning mechanism 20 can accurately press the workpiece, achieving accurate positioning of the workpiece. After the positioning fixture 10 is connected to the workpiece positioning mechanism 20, the movement of the positioning fixture 10 and the workpiece positioning mechanism 20 can be synchronized. After the positioning fixture 10 moves from the first position to the second position, the workpiece positioning mechanism 20 can follow the positioning fixture 10 and move synchronously to the second position, allowing the workpiece to move from the first position to the second position while maintaining its positioning, adapting to changes in processing requirements. Preferably, the positioning fixture 10 has different shapes and structures depending on the workpiece structure to adapt to the workpiece. The positioning fixture 10 can use existing structures, so it will not be described in detail here. The present invention provides two sets of workpiece processing equipment 100 in parallel, and correspondingly, two sets of positioning fixtures 10 are provided to improve processing efficiency, but it is not limited to this. Preferably, the above-mentioned second position is the position for processing the workpiece, but it is not limited to this.
[0028] It is worth noting that the synchronous movement of the workpiece positioning mechanism 20 and the positioning fixture 10 means that the movement between the workpiece positioning mechanism 20 and the positioning fixture 10 is carried out simultaneously, that is, they start and stop at the same time, and there is no delay between them.
[0029] like Figures 1 to 5 As shown, the workpiece positioning mechanism 20 and the positioning fixture 10 are arranged to slide in the same direction, allowing them to slide more directly and smoothly between the first and second positions. "In the same direction" should be understood as the workpiece positioning mechanism 20 and the positioning fixture 10 moving in the same direction. The workpiece positioning mechanism 20 is located on one side of the positioning fixture 10 and has a cantilever structure. This design prevents interference between the external machining mechanism and the workpiece positioning mechanism, thus avoiding impact on machining. In this embodiment, the external machining mechanism is a locking mechanism. The cantilever design of the workpiece positioning mechanism 20 simplifies its structure and enables automatic locking.
[0030] like Figures 1 to 5As shown, the workpiece positioning mechanism 20 includes a pressing structure 21 and an alignment connector 22. The positioning fixture 10 is provided with an alignment connection part (not shown) that mates with the alignment connector 22. The pressing structure 21 simultaneously presses the workpiece when the alignment connector 22 is connected to the alignment connection part. When the alignment connector 22 is connected to the alignment connection part, the pressing structure 21 simultaneously presses the workpiece, so that when the positioning fixture 10 and the workpiece positioning mechanism 20 are aligned, the pressing and positioning of the workpiece by the pressing structure 21 is performed synchronously, avoiding waiting and improving processing efficiency. For example, the alignment connector 22 is a pin structure and the alignment connection part is a slot structure, but it is not limited to these. Furthermore, the alignment connector 22 is installed on the pressing structure 21, and the pressing structure 21 is a cantilever structure. In this way, the movement of the pressing structure 21 and the alignment connector 22 is always synchronized, and the structure is simple. For example, the pressing structure 21 is a long rod structure, but it is not limited to these. Of course, depending on actual needs, in other embodiments, the pin structure can also be set on the positioning fixture 10, and correspondingly, the slot structure can be set on the pressing structure 21, which can also achieve the docking connection between the positioning fixture 10 and the workpiece positioning mechanism 20.
[0031] like Figures 1 to 5 As shown, the pressing structure 21 is slidably arranged, and has at least one operating position close to the positioning fixture 10 and an initial position away from the positioning fixture 10. When the positioning fixture 10 is in the first position, the pressing structure 21 slides from the initial position to the operating position, so that the pressing structure 21 presses the workpiece and simultaneously drives the alignment connector 22 to dock with the docking connection part. The pressing structure 21 can be operated easily, realizing easy and quick pressing of the workpiece and quick docking of the positioning fixture 10 with the workpiece positioning mechanism 20. Preferably, the pressing structure 21 is arranged in an up-and-down sliding manner, but it is not limited to this. Further, a plurality of pressing heads 23 are installed on the pressing structure 21. The pressing heads 23 are installed at the free end of the pressing structure 21, and the alignment connector 22 is installed at the other end of the pressing structure 21 away from its free end. The pressing heads 23 and the alignment connector 22 are located on the same side of the pressing structure 21. The pressure head 23 provides a more stable clamping force on the workpiece and avoids obstruction. Since the pressure head 23 is separated from the alignment connector 22, in this embodiment, the insertion of the pin structure into the slot structure and the clamping action of the pressure head 23 on the workpiece do not interfere with each other. For example, two pressure heads 23 are installed at the free end of the pressure structure 21, but this is not a limitation. Depending on actual needs, more or fewer pressure heads 23 can be installed at the free end of the pressure structure 21.
[0032] like Figures 1 to 5As shown, the workpiece positioning mechanism 20 also includes an action driver 24 and a displacement mounting bracket 25. The action driver 24 is mounted on the displacement mounting bracket 25, and the pressing structure 21 is slidably mounted on the displacement mounting bracket 25. The pressing structure 21 is mounted on the output end of the action driver 24, and the action driver 24 drives the pressing structure 21 to slide between the initial position and the operating position. The action driver 24 can automatically drive the pressing structure 21 to move. Preferably, in this embodiment, the displacement mounting bracket 25 is equipped with a motion slide rail 26 arranged in the vertical direction, and the pressing structure 21 is slidably mounted on the motion slide rail 26, but it is not limited to this. For example, the action driver 24 is a cylinder, specifically, the action driver 24 is a double cylinder. Of course, depending on actual needs, the action driver 24 can also adopt a linear motor or other structure, so it is not limited to this.
[0033] like Figures 1 to 5 As shown, the workpiece positioning mechanism 20 is arranged in a linear sliding manner between the first position and the second position, so that the workpiece positioning mechanism 20 can quickly and stably move back and forth between the first position and the second position. Specifically, the workpiece processing equipment 100 of the present invention also includes a slide rail structure 30 and a displacement driver 40. The slide rail structure 30 extends along the sliding direction of the workpiece positioning mechanism 20, and the displacement mounting bracket 25 is slidably mounted on the slide rail structure 30. The displacement mounting bracket 25 is mounted on the output end of the displacement driver 40, and the displacement driver 40 drives the workpiece positioning mechanism 20 to slide on the slide rail structure 30. The displacement driver 40 can automatically drive the workpiece positioning mechanism 20 to slide. For example, in this embodiment, the displacement driver 40 is a cylinder. Of course, depending on actual needs, the displacement driver 40 can also adopt a linear motor or other structure, so it is not limited to this.
[0034] like Figures 1 to 5As shown, when the workpiece positioning mechanism 20 moves to the second position, it is blocked, so that the positioning fixture 10 and the workpiece positioning mechanism 20 stop at the second position. Specifically, a blocking structure 50 is installed at the second position. When the workpiece positioning mechanism 20 moves to the second position, the blocking structure 50 applies a force to the workpiece positioning mechanism 20, and the direction of the force is opposite to the direction of movement of the workpiece positioning mechanism 20. The force applied to the workpiece positioning mechanism 20 by the blocking structure 50 can provide a buffering and limiting effect for the workpiece positioning mechanism 20, so that the workpiece positioning mechanism 20 stops more smoothly at the second position. Specifically, the workpiece positioning mechanism 20 is equipped with a stop structure 27. The blocking structure 50 includes an elastic structure 51, which is arranged opposite to the stop structure 27. When the workpiece positioning mechanism 20 is about to reach the second position, the elastic structure 51 abuts against the workpiece positioning mechanism 20, providing a buffer for the workpiece positioning mechanism 20. For example, the elastic structure 51 is a spring, but it is not limited to this. The blocking structure 50 and the stop structure 27 are both block-shaped parts, but they are not limited to this. The blocking structure 50 is installed on the side of the slide rail structure 30, but is not limited thereto.
[0035] like Figures 1 to 5 As shown, the workpiece processing equipment 100 of the present invention also includes a fixture driver 60. A positioning fixture 10 is mounted on the output end of the fixture driver 60, and the fixture driver 60 drives the positioning fixture 10 to move between a first position and a second position. For example, the fixture driver 60 is a motor drive assembly, that is, a combination of a motor and a lead screw and nut pair, but it is not limited thereto. Of course, depending on actual needs, the fixture driver 60 can also adopt a structure such as a hydraulic cylinder. The fixture driver 60 can automatically drive the positioning fixture 10 to move. Preferably, the positioning fixture 10 also slides linearly between the first position and the second position. Specifically, the positioning fixture 10 is slidably mounted on a displacement slide rail 70, and the positioning fixture 10 slides linearly via the displacement slide rail 70. The displacement slide rail 70 extends along the sliding direction of the positioning fixture 10. It should be noted that, in this embodiment, the sliding direction of the positioning fixture 10 and the workpiece positioning mechanism 20 is the Y-axis direction, but it is not limited thereto.
[0036] The working principle of the workpiece processing equipment 100 of the present invention is described below: In the initial state, the positioning fixture 10 and the workpiece positioning mechanism 20 are both in the first position. A workpiece is placed into the positioning fixture 10, and the action driver 24 drives the pressing structure 21 to move downward, causing the pressing structure 21 to slide down from the initial position to the action position. The pressing head 23 presses the workpiece tightly, and the alignment connector 22 (pin structure) is inserted into the mating connection part (slot structure). Next, the fixture driver 60 drives the positioning fixture 10 to slide from the first position to the second position. At the same time, the displacement driver 40 drives the workpiece positioning mechanism 20 to slide from the first position to the second position. The positioning fixture 10 and the workpiece positioning mechanism 20 slide synchronously. When the workpiece positioning mechanism 20 is about to move to the second position, it is blocked by the elastic structure 51, so that the positioning fixture 10 and the workpiece positioning mechanism 20 stop synchronously and bufferably in the second position. Next, the motion actuator 24 drives the pressing structure 21 to move upward, causing it to slide from the operating position back to the initial position. The pressing head 23 releases its pressure on the workpiece, and the pin structure moves away from the slot structure, achieving a reset. Subsequently, the displacement actuator 40 drives the workpiece positioning mechanism 20 to slide from the second position to the first position, resetting the workpiece positioning mechanism 20. At this time, the positioning fixture 10 remains in the second position for processing. After processing is completed, the fixture actuator 60 drives the positioning fixture 10 to slide from the second position to the first position, resetting the positioning fixture 10. This completes the positioning and loading of one workpiece. By repeating this process, different workpieces can be positioned and loaded sequentially.
[0037] The above-disclosed examples are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are within the scope of the present invention.
