Abstract
Description
Technical Field
[0001] The utility model relates to the field of guide column processing, in particular to a square guide column grinding and positioning jig. Background Art
[0002] Guide sleeves are usually used in conjunction with guide posts and are a common accessory that serves a guiding role.
[0003] Most guide pins are round, but some are square to prevent rotation during use. To reduce friction between the square guide pin and the guide sleeve, the corners are often rounded to minimize friction. Therefore, the current processing method involves securing the square guide pin with a fixture and then grinding each edge individually using a grinder, resulting in low efficiency. Utility Model Content
[0004] The utility model aims to provide a square guide post grinding and positioning jig, which has the advantage of being able to improve grinding efficiency.
[0005] To achieve the above-mentioned and other related purposes, the present invention provides the following technical solutions: a square guide post grinding and positioning fixture, comprising:
[0006] An assembly column with a circular cross section, wherein an assembly hole is provided on the assembly column along the axial direction for inserting the square guide column and fixing the square guide column along the circumferential direction;
[0007] A fixed locking piece, used to lock and fix the square guide column to the assembly column;
[0008] A support seat, wherein a support wheel is rotatably connected to the support seat, and at least two support wheels are provided, and the assembly column is overlapped with the support wheel;
[0009] a pressing wheel, applying a squeezing force on the assembly column directed toward the supporting wheel; and
[0010] The rotating driving member drives the supporting wheel to rotate so as to utilize friction force to drive the assembly column to rotate, and further drive the square guide column to rotate so that the square guide column contacts the grinding wheel of the grinder to grind the fillet.
[0011] Through the above technical solution, during installation, the square guide column to be processed is passed through the assembly hole provided on the assembly column, and then the square guide column and the assembly column are locked and fixed by a fixed locking piece; then the assembly column is placed on the support wheel, and the clamping wheel applies pressure to the assembly column to press the assembly column against the support wheel, and then the rotating driving piece drives the support wheel to rotate, and then the friction between the support wheel and the assembly column drives the assembly column to rotate, thereby driving the square guide column to rotate. When the square guide column rotates, it contacts the grinding wheel and can be ground. This solution grinds all edges at once by rotating the square guide column, thereby greatly improving the processing efficiency.
[0012] In one embodiment of the present invention, the fixing and locking member is configured as a locking screw, and the assembly column is provided with a threaded hole for the locking screw to be screwed into.
[0013] Through the above technical solution, the square guide column is pressed after the locking screw knob is turned, so that the square guide column and the assembly column are relatively fixed.
[0014] In one embodiment of the present invention, a rubber ring is circumferentially disposed on the support wheel to increase friction between the support wheel and the assembly column.
[0015] Through the above technical solution, the probability of slipping between the support wheel and the assembly column is reduced, so that the support wheel can stably drive the assembly column to rotate.
[0016] In one embodiment of the present invention, a rotating frame is hingedly connected to the support seat, and the pressing wheel is rotatably connected to the rotating frame. The rotating frame drives the pressing wheel to apply a squeezing force to the assembly column due to its own weight.
[0017] Through the above technical solution, the assembly column can be removed by lifting the rotating frame, and pressure can be applied to the assembly column by lowering the rotating frame. Disassembly and assembly are simple and convenient, and processing efficiency is further improved.
[0018] In one embodiment of the present invention, a counterweight is fixed to the rotating frame to increase the squeezing force applied to the assembly column and improve stability.
[0019] Through the above technical solution, the motor drives the turntable to rotate, increasing the pressure applied by the clamping wheel to the assembly column, thereby increasing the friction between the assembly column and the support wheel, and further improving the rotation stability of the assembly column.
[0020] In one embodiment of the present invention, a positioning mechanism is further included for positioning the square guide pillar in the axial direction.
[0021] Through the above technical solution, the processing accuracy is improved.
[0022] In one embodiment of the present invention, the positioning mechanism includes: a positioning support frame fixed to the support seat; a positioning block slidably assembled on the positioning support frame, the sliding direction of the positioning block is the same as the axial direction of the square guide column, and the positioning block is abutted against one end of the square guide column; and a positioning locking member for locking the positioning block and the positioning support frame when the positioning block is in a preset position.
[0023] Through the above technical solution, the position of the positioning block is adjusted by sliding the positioning block on the positioning support frame, and then the processing position of the square guide column is adjusted. After adjusting to the preset position, the positioning block is locked and fixed using a locking piece. The positioning of the square guide column can be completed, and only one positioning is required when processing the same batch of square guide columns. When replacing the square guide column, the square guide column can be offset against the positioning block, which makes disassembly and assembly faster and further improves the processing efficiency.
[0024] In one embodiment of the present invention, the positioning locking member is configured as a positioning locking screw, a screw hole is provided on the positioning support frame, and the positioning locking member passes through the screw hole to press and fix the positioning block.
[0025] Through the above technical solution, the positioning locking screw is screwed into the screw hole to press the positioning block, which can complete the fixation of the positioning block, and the fixation is convenient and fast.
[0026] As described above, the square guide post grinding and positioning jig of the present invention has the following beneficial effects:
[0027] During installation, the square guide column to be processed is passed through the assembly hole provided on the assembly column, and then the square guide column and the assembly column are locked and fixed by fixing the locking piece; then the assembly column is placed on the support wheel, and the clamping wheel applies pressure to the assembly column to press the assembly column against the support wheel, and then the rotating driving piece drives the support wheel to rotate, and then the friction between the support wheel and the assembly column drives the assembly column to rotate, thereby driving the square guide column to rotate. When the square guide column rotates, it contacts the grinding wheel and can be ground. This solution grinds all edges at once by rotating the square guide column, which greatly improves the processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
