Description

Technical Field

[0001] The utility model relates to the technical field of machine tool processing positioning, in particular to a positioning mechanism for machine tool processing. Background Art

[0002] CNC machine tool is the abbreviation of digital control machine tool, which is an automated machine tool equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the CNC device through information carriers. After calculation and processing, the CNC device sends various control signals to control the movement of the machine tool and automatically process the parts according to the shape and size required by the drawing.

[0003] When a machine tool is processing a part, the part is usually clamped in the fixture of the machine tool, and then the operator manually operates the tool on the machine tool to touch the part lightly. After the tool contacts the part, the contact position is used as the positioning zero point. However, when performing processing positioning, novice machining operators often tend to operate the tool to contact the part at a relatively fast speed, which can easily cause damage to the tool head. As a result, the frequency of tool damage caused by novice machining operators when using machine tools for processing positioning is relatively high. For this reason, we propose a positioning mechanism for machine tool processing. Utility Model Content

[0004] The main purpose of the utility model is to provide a positioning mechanism for machine tool processing. A positioning mechanism for protecting the machine tool tool is arranged between the tool holder and the machine tool tool. The machine tool tool can be positioned close to the part clamped by the machine tool under the protection of the positioning mechanism, so that the machine tool tool is not easy to hit the part during positioning. Machining personnel can use the positioning mechanism of the utility model to assist themselves in machine tool positioning operations during the novice period, avoiding excessively high frequency of tool damage when machining personnel operate the machine tool processing positioning during the novice period, and can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A positioning mechanism for machine tool processing comprises a base handle, a side plate surface of the base handle is clamped with a positive touch plate, and a pressure plate is fixed to the base handle behind the positive touch plate, the pressure plate is placed on the upper surface of the machine tool tool, and the pressure plate and the machine tool tool are clamped in the frame groove of the tool rack, and the mounting hole of the tool rack is three-point screwed with a fastening bolt for crimping the machine tool tool, and the pressure plate in the tool rack is spun by one group of bolt bodies of the fastening bolt, and the plate body of the pressure plate is provided with a bayonet clamped outside the fastening bolt in the middle of the tool rack, and a rubber guard plate is bonded to the plate surface of the positive touch plate facing the machine tool tool, an outer seat is welded to the outer plate surface of the base handle away from the pressure plate, and a U-shaped cavity is recessed on the seat body surface of the outer seat, and a fixed pit for clamping a rolling ball is recessed on the bottom cavity wall of the U-shaped cavity.

[0007] Furthermore, a hanging groove is vertically provided on the surface of the base handle on one side of the positive touch plate, and a hanging plate welded outside the positive touch plate is inserted into the groove cavity of the hanging groove; the positive touch plate can be hung on the hanging groove with the help of the hanging plate to complete the installation with the base handle.

[0008] Furthermore, the plate body of the hanging plate is an L-shaped plate body, the groove body of the hanging groove is an L-shaped groove body, and the groove body depth of the hanging groove is less than the height of the base handle rod; the L-shaped plate body of the hanging plate can be stuck in the L-shaped groove body of the hanging groove to obtain better hanging support.

[0009] Furthermore, the bayonet is arranged outside the side edge of the pressure plate away from the rubber guard plate, and the cavity of the bayonet is a U-shaped cavity; the pressure plate can be clamped against the fastening bolt in the middle of the tool holder to obtain support with the help of the bayonet.

[0010] Furthermore, the pit of the fixed pit is a shallow groove body of a conical groove cavity; the fixed pit of the conical groove cavity can slightly fix the rolling ball, and when the movement speed at the outer seat is too high, the rolling ball can leave the fixed pit and roll in the U-shaped cavity.

[0011] Furthermore, the height of the cavity wall of the U-shaped cavity is greater than the spherical diameter of the rolling ball; the rolling ball is not easy to roll outward in the deeper cavity of the U-shaped cavity.

[0012] Furthermore, the block of the rubber guard plate is a solid rubber block, and the solid rubber block of the rubber guard plate has the same height as the positive touch plate; when the positive touch plate is impacted and deformed, the rubber guard plate itself can elastically deform to buffer the force exerted by the positive touch plate on the machine tool tool.

[0021] Among them, a hanging groove 9 is vertically opened on the surface of the base handle 1 on one side of the positive touch plate 2, and a hanging plate 10 welded to the outside of the positive touch plate 2 is inserted into the groove cavity of the hanging groove 9; the positive touch plate 2 can be hung in the hanging groove 9 with the help of the hanging plate 10 to complete the installation with the base handle 1.

[0022] Among them, the plate body of the hanging plate 10 is an L-shaped plate body, the groove body of the hanging groove 9 is an L-shaped groove body, and the groove body depth of the hanging groove 9 is less than the handle rod height of the base handle 1; the L-shaped plate body of the hanging plate 10 can be stuck in the L-shaped groove body of the hanging groove 9 to obtain better hanging support.

[0023] Among them, the bayonet 11 is opened outside the side plate edge of the pressure plate 3 away from the rubber guard plate 8, and the cavity of the bayonet 11 is a U-shaped cavity; with the help of the bayonet 11, the pressure plate 3 can be clamped on the fastening bolt 14 in the middle of the tool holder 13 to obtain support.

[0024] Among them, the pit of the fixed pit 6 is a shallow groove body of a conical groove cavity; the fixed pit 6 of the conical groove cavity can slightly fix the ball 7, and when the movement speed at the outer seat 4 is too high, the ball 7 can break away from the fixed pit 6 and roll in the U-shaped cavity 5.

[0025] The wall height of the U-shaped cavity 5 is greater than the spherical diameter of the ball 7 ; the ball 7 is not easy to roll outward in the deeper cavity of the U-shaped cavity 5 .

[0026] Among them, the block of the rubber guard plate 8 is a solid rubber block, and the solid rubber block of the rubber guard plate 8 has the same plate height as the positive touch plate 2; when the positive touch plate 2 is impacted and deformed, the rubber guard plate 8 itself can elastically deform to buffer the force applied by the positive touch plate 2 to the machine tool tool 12.

[0027] It should be noted that the utility model is a positioning mechanism for machine tool processing. When a part is clamped at the fixture of the machine tool and the machine tool tool needs to be positioned for processing, the fastening bolt 14 of the tool post 13 close to the part can be screwed up, and then the pressure plate 3 on one side of the base handle 1 can be put into the screwed fastening bolt 14 and pressed on the top of the machine tool tool 12, and then the pressure plate 3 is clamped to the rear fastening bolt 14 of the tool post 13 with the bayonet 11, and then the screwed fastening bolt 14 is screwed back. The machine tool 12 is rotated downward, so that the fastening bolt 14 presses the pressure plate 3 on the surface of the machine tool tool 12, and the positive touch plate 2 with the rubber guard plate 8 is hung on the hanging groove 9 of the base handle 1 by means of the hanging plate 10 for clamping, so that the rubber guard plate 8 can contact the tool head of the machine tool tool 12. When the machining personnel manually operate the machine tool, so that the machine tool tool 12 at the tool rack 13 is close to the part, the machine tool tool 12 contacts the part with the positive touch plate 2 at the base handle 1, and then the machine tool operator uses this position as the machining positioning of the machine tool Zero point, and measure the thickness size parameters of the positive touch plate 2 and the rubber guard plate 8, and input this parameter as compensation data into the CNC system of the machine tool for positioning error compensation. When the base handle 1 moves too fast, resulting in an excessive movement speed at the outer seat 4, the ball 7 can break away from the fixed pit 6 and roll in the U-shaped cavity 5. At this time, the machine tool operator will notice that the machine tool tool 12 moves too fast and reduces the feed speed, and puts the ball 7 back into the fixed pit 6. After the positioning is completed, the machining personnel can unscrew the fastening bolt 14 pressing the pressure plate 3, and then pull the pressure plate 3 out from between the tool holder 13 and the machine tool tool 12, thereby removing the positioning mechanism of the utility model, and then re-screw the fastening bolt 14, and the machine tool tool 12 can perform part processing normally. The machining personnel can use the positioning mechanism of the utility model to assist themselves in the machine tool positioning operation during the novice period, so as to avoid excessively high frequency tool damage when the machining personnel operate the machine tool processing and positioning during the novice period.
