[0036] The evaporator processing line is generally in the form of a speed chain, and currently the screwing of the evaporator is mostly completed manually. The screw position is at a position deviated downward on the side of the evaporator. If automatic screwing is used, the mechanical arm is difficult to cut in at this position, and the evaporator needs to be rotated by 90 degrees so that the screw space faces upward. Therefore, based on the above needs, the present embodiment provides a tool positioning device 100.

[0037] Please refer to Figures 1 to 7 The present embodiment discloses a tool positioning device 100, which is used for positioning and angle adjustment of an evaporator and the like to be positioned. For example, when the evaporator is positioned and adjusted, it can be taken out from the speed chain, turned over by 90 degrees after positioning, so that the surface to be screwed faces upward, thereby facilitating automatic screwing.

[0038] The tool positioning device 100 comprises a lifting mechanism 1, a positioning mechanism 2 and a clamping jaw mechanism 3.

[0039] The lifting mechanism 1 is used for driving the positioning mechanism 2 to perform lifting action in a first direction.

[0041] The clamping jaw mechanism 3 is used for driving the to-be-positioned piece to rotate to complete angle adjustment.

[0042] In the present embodiment, the first direction is the vertical direction, and the second direction is the horizontal direction. Specifically, the lifting mechanism 1 is used for driving the positioning mechanism 2 to move up and down in the vertical direction, thereby completing the taking and placing action of the to-be-positioned piece. The positioning mechanism 2 is used for driving the clamping jaw mechanism 3 to move forward and backward in the horizontal direction, thereby adjusting the to-be-positioned piece to the matching position of the screwing mechanism. The clamping jaw mechanism then completes a certain angle rotation at the corresponding position, so that the screwing surface of the to-be-positioned piece faces upward, thereby facilitating screwing.

[0043] It can be understood that in other embodiments, the first direction and the second direction are not limited to the vertical direction and the horizontal direction, but are two mutually perpendicular directions arranged in any other direction.

When the two groups of lifting guide rail assembly 15 and lifting guide rail assembly 16 jointly perform the lifting action on the positioning mechanism 2 and the jaw mechanism 3 controlled by the lifting driving unit, it is more stable and smoother.

[0046] Further, the lifting driving unit comprises: a lifting cylinder 12, and a floating joint 13 connected to the driving end of the lifting cylinder 12; the lifting cylinder 12 is fixedly connected to the lifting mounting plate 11, and the floating joint 13 is connected to the positioning mechanism 2. The floating joint 13 is used to connect the positioning mechanism 2 and the lifting cylinder 12, so that a certain activity space is kept between them to avoid damage caused by rigid connection.

[0047] The lifting mounting plate 11 is a vertically arranged plate structure, which is used to support the whole tool positioning device 100, so the lifting mounting plate 11 can be installed on the workpiece conveying line, such as the base of the multiple-speed chain, etc. The lifting mounting plate 11 can also be connected and supported by an independent support base. At this time, the distance and height between the tool positioning device 100 and the conveying line need to be adjusted.

[0048] Specifically, the lifting guide rail assembly 15 and the lifting guide rail assembly 16 are structurally identical, and the lifting guide rail assembly 15 is taken as an example for structural description in this embodiment, which comprises: a lifting guide connecting piece 153, a lifting guide rail 151 connected to the lifting guide connecting piece 153, and a lifting slider 152 slidingly connected to the lifting guide rail 151, and the lifting slider 152 is further connected to the lifting mounting plate 11.

[0054] Among them, the positioning driving unit comprises a positioning cylinder 21 connected to the positioning mounting plate 20, and a floating joint 22 connected to the driving end of the positioning cylinder 21; the floating joint 22 is connected to the clamping jaw mechanism 3.

The two groups of positioning guide assemblies 23 and 24 are the same structure, and the positioning guide assembly 23 is taken as an example, which comprises a positioning guide rail 231 and a positioning sliding block 232 slidingly connected to the positioning guide rail 231, and the positioning sliding block 232 is connected to the positioning mounting plate 20.

[0056] Among them, the positioning mechanism 2 is used for driving the to-be-positioned member to move linearly in the horizontal direction, specifically, the positioning cylinder 21 drives the clamping jaw mechanism 3 to move forward or backward in the horizontal direction, so that the clamping jaw mechanism 3 grasps the preset position of the to-be-positioned member.

[0057] It can be understood that the above-mentioned positioning cylinder 21 can also be replaced by other arbitrary existing linear power modules, such as a lead screw module, a linear module, an electric cylinder or an electric push rod, etc.

[0058] In this embodiment, in order to facilitate assembly, the positioning guide rail 231 is also connected to a positioning connecting piece 25, one side end of the positioning connecting piece 25 is fixedly connected to the clamping jaw mechanism 3.

[0059] Please refer again to Figure 6 and Figure 7The jaw mechanism 3 comprises a jaw mounting plate 31, a fixed jaw 32 connected to one end of the jaw mounting plate 31, and a movable jaw 33 movably connected to the other end of the jaw mounting plate 31. The fixed jaw 32 and the movable jaw 33 are oppositely arranged to form an opening and closing jaw. Here, the movable jaw 33 refers to the movement away from or close to the fixed jaw 32, that is, the fixed jaw 32 and the movable jaw 33 together form an opening and closing jaw, which can automatically complete the taking and placing action of the positioning piece.

[0060] Further, the movable jaw 33 comprises a first mounting plate 331 and a driven turntable 332 rotatably connected to the first mounting plate 331. The fixed jaw 32 comprises a second mounting plate 321, a rotary drive unit 322 connected to the second mounting plate 321, and a driving end of the rotary drive unit 322.

The driving turntable 323 and the driven turntable 332 together clamp the positioning piece, and under the driving of the rotary drive unit 322, the positioning piece rotates with the driving turntable 323.

[0061] In this embodiment, the rotary drive unit 322 can be a servo motor or other driving module that can complete a set rotation angle at a time.

[0062] When the driving turntable 323 and the driven turntable 332 clamp the positioning piece with a specific structure, the driving turntable 323 and the driven turntable 332 can also be replaced by other suitable jaw pieces.

[0063] In this embodiment, the movable jaw 33 is movably connected to the jaw mounting plate 31 by the following mechanism.

[0066] The following will be combined with the drawings of the embodiments of the present application again Figures 1 to 7 Briefly describe the working process of the tool positioning device 100:

[0067] When the positioning member (such as an evaporator) is conveyed from the speed chain to the position of the tool positioning device 100, the lifting mechanism 1 drives the positioning mechanism 2 and the jaw mechanism 3 to descend synchronously, the initial state of the jaw mechanism 3 is that the jaw opening is in an open state, after descending to the set height, the positioning mechanism 2 acts again to drive the jaw mechanism 3 to move transversely to the set clamping position, the jaw driving unit drives the movable jaw 33 to move close to the fixed jaw 32, until the positioning member is clamped and fixed, finally the rotating driving unit 322 of the jaw mechanism 3 acts to drive the positioning member to rotate by a set angle, so as to complete the positioning and rotation of the positioning member, and thus the required surface of the positioning member is rotated to the corresponding position.

[0068] The tool positioning device of the embodiment realizes the processes of taking, placing, positioning and rotating adjustment of the positioning member through the cooperation of the lifting mechanism, the positioning mechanism and the jaw mechanism, has a simple structure, is fully automatic, and has high processing efficiency.
