[0003] The patent application with the publication number of CN221020233U discloses a positioning device for power module processing. Paragraph 0031 of its specification discloses that: by providing a scraping blade at the bottom of the clamping plate, when the clamping plate moves on the top of the housing, the scraping blade will clean a part of the area on the top of the housing.

Detailed implementation manners

[0029] Now, the present utility model will be further described in detail with reference to the attached drawings.

[0030] Please refer to Figures 1-4 As shown, in this embodiment, a positioning device for power module processing is provided, including a shell 1. Two L-shaped plates 103 are slidably fitted on the upper side of the shell 1. A clamping plate 105 is clamped and fitted on one side of the L-shaped plate 103, and a scraping blade 110 is installed at the bottom of the clamping plate 105;

[0031] Two guide rods 201 located on the upper side of the shell 1. One end of the guide rod 201 is elastically and slidably fitted with a right trapezoid 202. The bottom of the right trapezoid 202 is attached to the upper side of the shell 1, and a traction rope 205 is installed between one side of the right trapezoid 202 and one end of the scraping blade 110.

[0032] Working principle:

[0033] First, place the workpiece on the upper side of the housing 1, and then slide the L-shaped plate 103. The L-shaped plate 103 drives the scraping blade 110 to slide through the clamping plate 105. The clamping plate 105 positions the workpiece on the upper side of the housing 1. The scraping blade 110 drives the impurities on the upper side of the housing 1 to move. The scraping blade 110 drives the right-angled trapezoid 202 to slide on the guide rod 201 through the traction rope 205. When the workpiece processing is completed, slide the L-shaped plate 103 in the reverse direction. The L-shaped plate 103 drives the clamping plate 105 to release the positioning of the workpiece, and then the worker removes the processed workpiece. Similarly, the right-angled trapezoid 202 is reset under the action of elasticity, and the reset right-angled trapezoid 202 drives the impurities to move into the inside of the storage box for storage processing.

[0034] The provided right-angled trapezoid 202 enables the traction rope 205 to drive the right-angled trapezoid 202 to slide under the action of the scraping blade 110, so as to move the impurities forming a straight line through the right-angled trapezoid 202 and perform storage processing through the storage box, reducing the problem of impurity accumulation on the upper side of the housing 1 and making the process of the scraping blade 110 cleaning impurities more convenient.

[0035] To make the sliding process of the right-angled trapezoid 202 at one end of the guide rod 201 in this embodiment more stable, the following structure is improved, as Figures 1-4 shown, two fixing blocks 2 are installed on the upper side of the housing 1 in this embodiment. The first end of the guide rod 201 is installed on one side of the fixing block 2. A guide hole 203 is opened at one end of the right-angled trapezoid 202. The second end of the guide rod 201 is located inside the guide hole 203. A spring 204 is installed between the right-angled trapezoid 202 and the fixing block 2. The spring 204 is sleeved on the periphery of the guide rod 201. Two first pulleys 111 and two second pulleys 112 are installed on the upper side of the housing 1. The traction rope 205 cooperates with the first pulley 111 and the second pulley 112.

[0036] When this embodiment is in use, first pull the traction rope 205. The traction rope 205 moves on the first pulley 111 and the second pulley 112. The traction rope 205 drives the right-angled trapezoid 202 to slide. The right-angled trapezoid 202 slides on the guide rod 201 through the guide hole 203 and compresses the spring 204, thereby completing the sliding of the right-angled trapezoid 202.

[0037] The provided guide hole 203 enables the right-angled trapezoid 202 to slide on the guide rod 201 through the guide hole 203 under the action of the traction rope 205, and guides the sliding direction of the right-angled trapezoid 202 through the guide hole 203, improving the stability of the right-angled trapezoid 202 during sliding.

[0038] To make the clamping process of the clamping plate 105 in this embodiment more stable, the following structure is improved, as Figures 1-4As shown in the figure, two T-shaped grooves 104 are formed on one side of the L-shaped plate 103 of this embodiment. Two T-shaped plates 106 are installed on one side of the clamping plate 105. The T-shaped plates 106 are located inside the T-shaped grooves 104. A threaded hole 108 is formed on the L-shaped plate 103. A bolt 113 is in threaded fit inside the threaded hole 108. A through hole 107 is formed on one side of the clamping plate 105. The bolt 113 is located inside the through hole 107. Two electric push rods 102 are installed on the housing 1. One side of the L-shaped plate 103 is installed on the output end of the electric push rod 102. A plurality of rubber protrusions 109 are evenly installed on one side of the clamping plate 105. A grinding member 101 is installed on the upper side of the housing 1. A plurality of support rods 114 are installed on the bottom of the housing 1.

[0039] When this embodiment is in use, first, the clamping plate 105 is placed on one side of the L-shaped plate 103. The clamping plate 105 drives the T-shaped plates 106 to be placed inside the T-shaped grooves 104. Then, the bolt 113 is placed inside the clamping plate 105 through the through hole 107. Then, the bolt 113 is rotated. The bolt 113 is in threaded fit inside the L-shaped plate 103 through the threaded hole 108, thereby completing the fixation of the clamping plate 105. The provided threaded hole 108 enables one end of the bolt 113 to position the clamping plate 105 on one side of the L-shaped plate 103 through the threaded hole 108, making the disassembly and assembly process of the clamping plate 105 more convenient.
