Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a convenient multi-angle inspection fixture for appearance inspection. Background Technology

[0002] Appearance inspection is a common industrial product manufacturing inspection process. It accurately analyzes the external shape of a product by photographing its appearance to determine whether the product meets the manufacturing standards. It is used to screen industrial products. The photographic inspection is fast and accurate. It can detect defects such as cracks, stains, bubbles, burrs, or discoloration on the product surface, and the inspection is convenient.

[0003] Currently, when workpiece surface roughness is inspected manually, the inspection tool inevitably shakes during the inspection process. To avoid this, using inspection fixtures is a commonly used method for workpiece surface roughness inspection. Suitable inspection fixtures are of great significance for the convenience of operation for inspection personnel and for improving their work efficiency.

[0004] When using inspection fixtures to inspect the roughness of various surfaces of a cutting tool, the position and angle of the machined surface to be inspected vary depending on the tool's usage requirements. Existing inspection fixtures cannot meet the inspection needs of different tool surfaces. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a convenient multi-angle appearance inspection fixture, which overcomes the shortcomings of the prior art and effectively solves the problem that the existing inspection fixtures cannot meet the inspection needs of different tool surfaces.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A convenient multi-angle appearance inspection fixture includes a base plate, a rotating rod rotatably connected to the top of the base plate, and a lower clamping block fixed to the top of the rotating rod. A fixing frame is fixed to one end of the top of the base plate, and lead screws are rotatably connected to the inner walls of both ends of the fixing frame. An adjustment mechanism is screwed to the wall of the lead screw, and a pressing mechanism is connected to the top of the outer wall of one side of the fixing frame. The adjustment mechanism includes a T-block, a connecting shell disposed on one side of the T-block, a bidirectional screw rotatably connected to the inner walls of both ends of the connecting shell, an adjustment plate screwed to both ends of the outer wall of the bidirectional screw, and a detection probe installed on the outer wall of one side of the adjustment plate. The pressing mechanism includes a fixing plate, a second handle screw screwed to the fixing plate, and an upper clamping block rotatably connected to the bottom of the second handle screw.

[0008] By abutting one end of the cutting tool against the top of the lower clamping block, and then rotating the second handle screw, the upper clamping block abuts against the top of the cutting tool. The cutting tool is rotated so that both sides of the cutting tool face the detection probes on both sides. The second servo motor drives the lead screw to rotate, and the rotating lead screw drives the screwed T-block to move vertically along the fixed frame. This causes the adjustment mechanism to move from the bottom of the cutting tool to the top of the cutting tool. The detection probes inspect the appearance of both sides of the cutting tool. For some special shapes, such as rhomboid cutting tools, the first servo motor can rotate the cutting tool through the rotating rod and the lower clamping block. In conjunction with the movement of the detection probes, a comprehensive appearance inspection of the cutting tool can be performed.

[0009] Preferably, a first servo motor is fixed to the top of the base plate on one side of the rotating rod, and gears that mesh with each other are sleeved and fixed on the output shaft of the first servo motor and the rod wall of the rotating rod.

[0010] The first servo motor drives the rotating rod to rotate through meshing gears.

[0011] Preferably, a second servo motor is mounted on the top of the fixing frame, and the output shaft of the second servo motor is connected and fixed to the top of the lead screw.

[0012] The second servo motor drives the lead screw to rotate.

[0013] Preferably, the T-block is screwed to the lead screw, and the T-block and the fixing frame are in sliding fit.

[0014] The rotating lead screw drives the screwed T-block to move vertically along the fixed frame.

[0015] Preferably, a sliding rod is inserted into one end of the outer wall of the T-shaped block, and a first handle screw is screwed into the other end of the outer wall of the T-shaped block.

[0016] The T-block is connected to the connecting shell by means of the first handle screw and slide bar.

[0017] Preferably, the first handle screw is rotatably connected to the connecting shell, and the slide rod is fixedly connected to the connecting shell.

[0018] Rotating the first handle screw, in conjunction with the sliding rod that is fixed to the connecting shell, allows adjustment of the distance between the connecting shell and the T-block.

[0019] Preferably, one end of the fixing plate is fixed with symmetrically distributed insertion rods, and the top of the outer wall of one side of the fixing frame is provided with symmetrically distributed insertion holes, and the insertion holes and insertion rods form an interference fit.

[0020] The pressing mechanism is connected and fixed to the fixed frame by inserting a rod into it.

[0021] The beneficial effects of this utility model are as follows:

[0022] By abutting one end of the cutting tool against the top of the lower clamping block, and then rotating the second handle screw to abut the top of the cutting tool against the upper clamping block, the adjusting mechanism moves from the bottom to the top of the cutting tool. The detection probe inspects the appearance of both sides of the cutting tool. For some special-shaped cutting tools, such as prismatic tools, the first servo motor can rotate the cutting tool through the rotating rod and the lower clamping block. In conjunction with the movement of the detection probe, a comprehensive appearance inspection of the cutting tool can be performed. This effectively solves the problem that existing detection clamps cannot meet the inspection needs of different cutting tool surfaces. Attached Figure Description

The adjustment mechanism 8 includes a T-shaped block 10, a connecting shell 13 disposed on one side of the T-shaped block 10, a bidirectional screw 14 rotatably connected to the inner walls of both ends of the connecting shell 13, an adjustment plate 15 screwed to both ends of the outer wall of the bidirectional screw 14, and a detection probe 16 installed on the outer wall of one side of the adjustment plate 15. The pressing mechanism 9 includes a fixed plate 17, a second handle screw 18 screwed to the fixed plate 17, and an upper clamping block 19 rotatably connected to the bottom of the second handle screw 18.

[0031] A first servo motor 4 is fixed to the top of the base plate 1 on one side of the rotating rod 2. The output shaft of the first servo motor 4 and the rod wall of the rotating rod 2 are both fitted with meshing gears. The first servo motor 4 drives the rotating rod 2 to rotate through the meshing gears. A second servo motor 7 is installed on the top of the fixed frame 5. The output shaft of the second servo motor 7 is connected and fixed to the top of the lead screw 6. The second servo motor 7 drives the lead screw 6 to rotate. The T-block 10 is screwed to the lead screw 6. The T-block 10 and the fixed frame 5 form a sliding fit. The rotating lead screw 6 drives the screwed T-block 10 to move vertically along the fixed frame 5.

[0032] One end of the outer wall of the T-block 10 is fitted with a movable slide rod 11, and the other end of the outer wall of the T-block 10 is screwed with a first handle screw 12. The T-block 10 is connected to the connecting shell 13 through the first handle screw 12 and the slide rod 11. The first handle screw 12 is rotatably connected to the connecting shell 13, and the slide rod 11 is fixedly connected to the connecting shell 13.

The insertion rods 20 are inserted into the fixing frame 5 to connect and fix the pressing mechanism 9 to the fixing frame 5.

[0033] Working principle:

[0034] During operation, one end of the cutter is brought into contact with the top of the lower clamping block 3, and then the second handle screw 18 is rotated to bring the upper clamping block 19 into contact with the top of the cutter. The cutter is rotated so that the two sides of the cutter face the detection probes 16 on both sides. The second servo motor 7 drives the lead screw 6 to rotate, and the rotating lead screw 6 drives the screwed T-block 10 to move vertically along the fixed frame 5. This causes the adjustment mechanism 8 to move from the bottom of the cutter to the top of the cutter. The appearance of the two sides of the cutter is inspected by the detection probes. For some special shapes, such as rhomboid cutters, the first servo motor 4 can rotate the cutter through the rotating rod 2 and the lower clamping block 3. In conjunction with the movement of the detection probes 16, a comprehensive appearance inspection of the cutter body can be performed.
