Description

Technical Field

[0001] The utility model relates to a spindle tool mounting device, belonging to the technical field of machinery. Background Art

[0002] As a professional equipment for processing and forming metal, wood and other materials, machine tools are one of the most important and basic equipment in manufacturing workshops. They are widely used in parts processing, mold manufacturing, machinery manufacturing, aviation manufacturing, railways, automobiles, electronics, ships and other industries. Among them, the spindle tool is a cutting tool used on the processing machine tool. It is installed on the spindle of the machine tool and is responsible for completing the processing task of the workpiece. The spindle tool is an important and basic component of the machine tool.

[0003] At present, in the assembly process of some machine tool equipment, it is necessary to first install the tool on the spindle, and then install the combination of the tool and the spindle on the machine tool. For this type of assembly process, the assembly of the spindle and the tool is generally completed by a press. Specifically, the spindle is first vertically set on the workbench of the press through a pad, and then the press is driven to slowly move toward the spindle so that the press contacts the cutting surface of the spindle. Finally, the press moves downward according to the amount of cutting of the spindle to press into the cutting surface of the spindle, and then the tool is manually inserted into the spindle to complete the installation of the tool. Among them, due to changes in the length, diameter, etc. of the spindle, it is necessary to adjust the position of the pad, which is cumbersome to operate, and the position for installing the tool is easily blocked by the pad, which makes it impossible to insert the tool. In the case of a long tool, it is even necessary to replace pads of different specifications, which further increases the complexity of the installation operation.

[0004] In addition, the use of a press to assemble the tool requires a control system and manual operation, which not only increases the manufacturing cost due to the high price of the press, but also because the press has great power, improper manual operation can easily cause damage to the spindle.

[0042] See also Figures 1 to 8 The spindle tooling device of the technical solution of the utility model comprises a base 100, a clamping mechanism 200, a pressing mechanism 300 and an adjusting mechanism 400. The clamping mechanism 200 is used to fix the spindle 500, and the clamping mechanism 200 is slidably arranged on the base 100. The pressing mechanism 300 is used to press the spindle 500 for a certain amount of cutting, and the pressing mechanism 300 is arranged on the base 100, and the pressing mechanism 300 abuts against the cutting surface 510 of the spindle 500. The adjustment mechanism 400 includes a mounting block 410, a screw rod 420, a connecting block 430 and a telescopic cylinder 440. The mounting block 410 is fixedly mounted on the base 100. The middle portion of the screw rod 420 is threadedly connected and penetrates the mounting block 410. The connecting block 430 is provided with a sliding channel 431. One end of the screw rod 420 close to the pressing mechanism 300 is slidably inserted into the inner wall of one end of the sliding channel 431. The telescopic rod 441 of the telescopic cylinder 440 is fixedly connected to the inner wall of the other end of the sliding channel 431. The cylinder body 442 of the telescopic cylinder 440 is fixedly connected to the clamping mechanism 200. Further, one end of the screw rod 420 away from the connecting block 430 is connected to the hand wheel 450.

[0043] See also Figure 4 When the telescopic cylinder 440 is in the retracted state, the telescopic cylinder 440 and the screw rod 420 are spaced apart. Figure 5 When the telescopic cylinder 440 is in the extended state, the telescopic rod 441 of the telescopic cylinder 440 abuts against the end of the screw rod 420, so that the cylinder body 442 of the telescopic cylinder 440 drives the clamping mechanism 200 to slide, thereby making the spindle 500 in the state of pressing into the cutting amount. Among them, when the screw rod 420 is in the initial position state, according to the cutting amount of the spindle 500, the length of the screw rod 420 extending into the sliding channel 431 is adjusted by the hand wheel 450 to adjust the abutment position of the telescopic rod 441 of the telescopic cylinder 440 and the screw rod 420, thereby adjusting the sliding stroke of the clamping mechanism 200.

[0044] See also Figure 1 to Figure 2 The clamping mechanism 200 is slidably arranged at the left end of the base 100, the spindle 500 is horizontally arranged and fixed on the clamping mechanism 200, the pressing mechanism 300 is fixedly arranged at the right end of the base 100, the tool-mounting end 520 of the spindle 500 is arranged on the pressing mechanism 300, and the cutting surface 510 of the spindle 500 is in contact with the pressing mechanism 300. When the clamping mechanism 200 drives the spindle 500 to slide horizontally to the right, the pressing mechanism 300 applies a rightward pressure to the cutting surface 510 of the spindle 500, so that the spindle 500 is in a device with a pressing amount of cutting, and the tool can be manually inserted into the tool-mounting end 520 of the spindle 500 to complete the assembly of the tool and the spindle 500.

[0045] Further, see Figure 4 and Figure 5 The cylinder body 442 of the telescopic cylinder 440 is fixedly connected to the clamping mechanism 200. When the telescopic rod 441 of the telescopic cylinder 440 extends to the left, when the telescopic rod 441 abuts against the end of the screw 420, the screw 420 is threadedly connected to the mounting block 410, so that the telescopic rod 441 cannot push the screw 420 to move to the left, so that the screw 420 limits the telescopic rod 441 from continuing to extend to the left, and the screw 420 has a rightward reverse thrust on the telescopic cylinder 440, so that the cylinder body 442 of the telescopic cylinder 440 moves to the right, thereby driving the clamping mechanism 200 and the main shaft 500 to move horizontally to the right, so that the pressing mechanism 300 fixed to the base 100 applies a pressure exceeding the left on the main shaft 500, and the cutting surface 510 of the main shaft 500 is pressed into the cutting amount.

[0046] Furthermore, during the tool installation process, pressure is first applied to the cutting surface 510 of the spindle 500, and then after the tool is inserted into the tool mounting end 520 of the spindle 500, the pressure is removed to reset the cutting surface 510 of the spindle 500, so that the tool is stuck in the spindle 500. The stroke of the cutting surface 510 moving under the pressure is the cutting amount. Different specifications of spindles 500 have different cutting amounts. During tool installation, the pressing stroke needs to be adjusted according to the cutting amount of the spindle 500. In the spindle tool installation device of the specific embodiment of the utility model, the sum of the leftward movement of the telescopic rod 441 of the telescopic cylinder 440 and the rightward movement of the cylinder body 442 of the telescopic cylinder 440 is equal to the total extension of the telescopic cylinder 440. Therefore, when the total extension of the telescopic cylinder 440 is constant, the leftward movement of the telescopic rod 441 can be adjusted by adjusting the contact position between the screw rod 420 and the telescopic rod 441, and then the rightward movement of the cylinder body 442 can be adjusted to adjust the pressing stroke of the cutting surface 510 according to the cutting amount of the spindle 500. Specifically, see Figure 4The screw rod 420 is threadedly connected to the mounting block 410, and the screw rod 420 is driven to rotate by the hand wheel 450 to adjust the length of the screw rod 420 inserted into the connecting block 430, thereby adjusting the contact position between the screw rod 420 and the telescopic rod 441 of the telescopic cylinder 440. The extension amount of the screw rod 420 is equal to the cutting amount of the main shaft 500. Specifically, the extension amount of the screw rod 420 is equal to the product of the number of lines and the pitch. Therefore, the number of turns that the hand wheel 450 needs to rotate can be calculated based on the known cutting amount of the main shaft 500 and the linear distance of one rotation of the screw rod 420. Therefore, the screw rod 420 is rotated by the hand wheel 450, and the stroke of the pressing mechanism 300 pressing into the cutting surface 510 can be adjusted according to the cutting amount of the main shaft 500.

[0047] Specifically, the spindle tool mounting device of the embodiment of the utility model first fixes the spindle 500 in the clamping mechanism 200, and then when the telescopic cylinder 440 is in a retracted state, the screw 420 is in an initial position. At this time, the telescopic rod 441 of the telescopic cylinder 440 is disengaged from the screw 420, and the cutting surface 510 of the spindle 500 is abutted against the pressing mechanism 300. Specifically, the pressing mechanism 300 is movably arranged on the base 100. By adjusting the distance between the pressing mechanism 300 and the clamping mechanism 200, the cutting surface 510 of the spindle 500 can be abutted against the pressing mechanism 300.

[0048] When the cutting surface 510 of the spindle 500 abuts against the pressing mechanism 300, the number of rotations of the handwheel 450 is obtained according to the cutting amount of the spindle 500 and the parameters of the screw 420, and the screw 420 is driven to rotate by the handwheel 450 so that the screw 420 extends into the interior of the connecting block 430 by the cutting amount. The telescopic cylinder 440 is started to extend the telescopic rod 441 to a preset extension amount. When the telescopic rod 441 contacts the screw rod 420, the cylinder body 442 of the telescopic cylinder 440 drives the clamping mechanism 200 and the spindle 500 to move, so that the pressing mechanism 300 presses into the cutting surface 510, so that the spindle 500 remains pressed into the cutting surface 510, and the tool is inserted into the tool-loading end 520 of the spindle 500. Then, the telescopic cylinder 440 is started to retract the telescopic rod 441, and the cutting surface 510 of the spindle 500 moves in the opposite direction and resets, so that the tool is clamped on the spindle 500, and the installation of the tool on the spindle 500 is completed. It can be understood that the preset extension amount of the telescopic cylinder 440 is the maximum stroke of the screw rod 420 in the sliding channel 431.

[0049] In some specific embodiments of the present invention, see Figure 1The base 100 includes a bracket consisting of six crossbars 110 and four vertical bars 120, wherein the clamping mechanism 200 and the pressing mechanism 300 are both arranged on the upper plane of the two longer crossbars 110 at the top, and the shorter crossbar 110 at the upper side is provided with a through hole, the center line of the through hole is arranged horizontally, and the connecting block 430 of the adjusting mechanism 400 is passed through the through hole to be fixedly connected with the crossbar 110. Figure 4 A threaded sliding channel 431 is provided in the middle of the connecting block 430, and the middle of the screw rod 420 is inserted into the sliding channel 431. The screw rod 420 is rotatably threadedly connected to the connecting block 430, and both ends of the screw rod 420 protrude from both sides of the connecting block 430. Among them, one end of the screw rod 420 away from the pressing mechanism 300 (i.e., the outer side of the base 100) is connected to the hand wheel 450, so that the screw rod 420 can be rotated by the hand wheel 450 to adjust the protruding length of the end of the screw rod 420 close to the pressing mechanism 300.

[0050] In some specific embodiments of the present invention, see Figure 5 and Figure 6 The connecting block 430 is a hollow structure, and a sliding channel 431 is provided inside. The center line of the sliding channel 431 is horizontally arranged and is in the same straight line as the center line of the screw 420. The end of the screw 420 close to the pressing mechanism 300 is inserted into the sliding channel 431 of the connecting block 430. The screw 420 and the connecting block 430 can slide relative to each other. The opening of the sliding channel 431 away from the screw 420 is fixedly connected to the telescopic rod 441 of the telescopic cylinder 440, so that the connecting block 430 is driven to move to the left by the telescopic rod 441. When the screw 420 remains stationary, the connecting block 430 and the screw 420 slide relative to each other, and the telescopic rod 441 of the telescopic cylinder 440 can abut against the screw 420.

[0051] In some specific embodiments of the present invention, the adjustment structure further includes an abutment block 460, which is disposed at the end of the screw rod 420 away from the hand wheel 450, and the diameter of the abutment block 460 is larger than the end opening diameter of the sliding channel 431. Figure 5 and Figure 6, a socket 432 is provided at one end of the sliding channel 431 of the connecting block 430 away from the pressing mechanism 300, and the screw rod 420 is inserted into the connecting block 430 through the socket 432. The abutment block 460 is connected to the end of the screw rod 420 and is arranged in the sliding channel 431. The diameter of the abutment block 460 is not larger than the diameter of the sliding channel 431, and the diameter of the abutment block 460 is larger than the diameter of the socket 432 of the sliding channel 431, so as to prevent the screw rod 420 from being separated from the connecting block 430. It can be understood that when installing the tool, the screw rod 420 should be rotated first so that the left end face of the abutment block 460 abuts against the left inner wall of the sliding channel 431, that is, the screw rod 420 is in the initial position, and then adjusted so that the cutting surface 510 of the spindle 500 abuts against the pressing mechanism 300.

[0052] In some specific embodiments of the present invention, see Figure 1 and Figure 2 The clamping mechanism 200 includes a movable slide 210, a first clamping block 220, a support frame 230, a locking block 240 and a second clamping block 250. The movable slide 210 is slidably arranged on the base 100. The first clamping block 220 is arranged on the movable slide 210. The support frame 230 is arranged on the side of the first clamping block 220 away from the movable slide 210. The locking block 240 is movably arranged on the support frame 230. One end of the locking block 240 close to the first clamping block 220 is connected to the second clamping block 250. The spindle 500 is arranged between the second clamping block 250 and the first clamping block 220. When the locking block 240 is in a locked state, the opposite sides of the spindle 500 are respectively in contact with the second clamping block 250 and the first clamping block 220. When the locking block 240 is in an unlocked state, the second clamping block 250 is separated from the spindle 500. It should be noted that the locking block 240 can be set as a 7-shaped lock.

[0053] Specifically, the first clamping block 220 and the second clamping block 250 of the embodiment of the utility model are both provided with V-shaped grooves, and the openings of the two V-shaped grooves are arranged facing each other. The first clamping block 220 is arranged on the movable slide 210, and the opening of the V-shaped groove of the first clamping block 220 faces away from the movable slide 210. The support frame 230 is a quasi-inverted U-shaped structure, and the lower ends of the two vertical rods of the support frame 230 are respectively connected to the two sides of the V-shaped groove of the first clamping block 220, and the first clamping block 220 and the support frame 230 form a clamping channel. The transverse rod of the support frame 230 is provided with a clamping hole, and the center line of the clamping hole is arranged vertically. The locking block 240 is inserted into the clamping hole, the handle of the locking block 240 faces upward, and the lower end of the locking block 240 is connected to the second clamping block 250, and the V-shaped groove of the second clamping block 250 opens toward the first clamping block 220.

[0054] See also Figure 2, the spindle 500 is passed through the clamping channel, so that the lower side of the spindle 500 is placed on the first clamping block 220 and is set in the V-shaped groove, and the lower side of the spindle 500 abuts against the groove wall of the V-shaped groove of the first clamping block 220. When the locking block 240 is in the unlocked state, the second clamping block 250 is set above the spindle 500 and is separated from the spindle 500. Apply force to the locking block 240, so that the locking block 240 is switched from the unlocked state to the locked state, so that the second clamping block 250 moves downward and abuts against the upper side of the spindle 500. Under the interaction of the first clamping block 220 and the second clamping block 250, the spindle 500 is fixed on the clamping mechanism 200. After the locking block 240 is switched from the locked state to the unlocked state, the second clamping block 250 is separated from the spindle 500, and the spindle 500 can be moved out of the clamping mechanism 200.

[0055] In an application embodiment, the clamping mechanism 200 further includes a positioning block 260, which is disposed on the movable slide 210 and at an end of the first clamping block 220 away from the pressing mechanism 300, and the positioning block 260 abuts against the main shaft 500. Figure 1 and Figure 2 The structure of the positioning block 260 is the same as that of the first clamping block 220, and both are provided with a V-shaped groove, the groove of which faces away from the movable slide 210, and the end of the spindle 500 (the end away from the tool-mounting end 520 of the spindle 500) abuts against the groove wall of the V-shaped groove of the positioning block 260.

[0056] In an application embodiment, see Figure 1 The movable slide 210 is provided with a movable slide groove 211, and the first clamping block 220 and the positioning block 260 are provided on the movable slide 210 in a switchable installation position through the cooperation of the first screw and the movable slide groove 211. The front and rear sides of the first clamping block 220 and the positioning block 260 are respectively provided with threaded holes, and the first screw passes through the threaded holes and abuts against the bottom wall of the movable slide groove 211, so that the first clamping block 220 and the positioning block 260 are fixed on the movable slide 210. When the first screw is loosened so that the first screw is separated from the bottom wall of the movable slide groove 211, the position of the first clamping block 220 and the positioning block 260 on the movable slide 210 can be adjusted, thereby adjusting the distance between the cutting surface 510 of the spindle 500 and the pressing mechanism 300.

[0057] In an application embodiment, see Figure 1 and Figure 2 The clamping mechanism 200 further includes a guide rail 270 and a slider 280. The guide rail 270 is fixedly disposed on the base 100. The slider 280 is slidably disposed on the guide rail. The slider 280 is fixedly connected to the movable slide 210. Further, the cylinder body 442 of the telescopic cylinder 440 is fixedly connected to the movable slide 210 through two fixing blocks. Figure 1The fixed block is an L-shaped structure, the horizontal plate of the fixed block is fixedly connected to the bottom of the movable slide 210, and the vertical plate of the fixed block is connected to the left and right ends of the telescopic cylinder 440, wherein the fixed plate 321 on the left side is provided with a through hole, and the telescopic rod 441 of the telescopic cylinder 440 passes through the through hole and is connected to the connecting block 430. When the telescopic rod 441 of the telescopic cylinder 440 abuts against the screw rod 420 and the cylinder body 442 of the telescopic cylinder 440 moves, the movable slide 280 is driven to move in a direction away from or close to the pressing mechanism 300, thereby causing the main shaft 500 to move away from or close to the pressing mechanism 300.

[0058] In some specific embodiments of the present invention, see Figures 1 to 4 The pressing mechanism 300 includes an adjusting slide 310, a fixing assembly 320 and a pressing block 330. The adjusting slide 310 is fixedly connected to the base 100. The adjusting slide 310 is provided with an adjusting slot 311. The fixing assembly 320 is movably arranged on the adjusting slide 310 through the cooperation of a second screw 312 and the adjusting slot 311. The pressing block 330 is arranged on the fixing assembly 320 and abuts against the cutting surface 510 of the spindle 500. Figure 1 , the bottom end of the second screw 312 abuts against the bottom wall of the adjusting slot 311 of the adjusting slide 310, so that the fixing assembly 320 and the pressing block 330 are fixed on the adjusting slide 310. When the second screw 312 is loosened, so that the second screw 312 is separated from the bottom wall of the adjusting slot 311, the position of the fixing assembly 320 on the adjusting slide 310 can be adjusted, so that the distance between the pressing block 330 and the cutting surface 510 of the main shaft 500 can be appropriately adjusted according to the length of the main shaft 500 and the cutting amount required.

[0059] In an application embodiment, see Figure 1 and Figure 2 The fixing assembly 320 includes a fixing plate 321 and two side plates 322. The fixing plate 321 is connected to the adjusting slide 310. The two side plates 322 are symmetrically arranged on both sides of the fixing plate 321. Both sides of the pressing block 330 are respectively connected to the two side plates 322. One end of the main shaft 500 abuts against the pressing block 330 and is arranged between the two side plates 322. The fixing plate 321 is horizontally arranged on the adjusting slide 310. The fixing plate 321 is provided with a threaded hole. The second screw 312 is inserted into the threaded hole of the fixing plate 321 to abut against the adjusting slide 310. The two side plates 322 are vertically placed triangular plates. One right angle surface of the side plate 322 is connected to the side of the fixing plate 321 away from the adjusting slide 310. The other right angle surface of the side plate 322 is connected to the pressing block 330. The inclined surface of the side plate 322 faces away from the first clamping block 220.

[0060] Further, see Figure 1 and Figure 8The pressing block 330 is provided with a V-shaped groove, the groove is facing away from the adjusting slide 310, the peripheral wall of the tool-mounting end 520 of the spindle 500 abuts against the inner wall of the V-shaped groove of the pressing block 330, and the tool-mounting end 520 of the spindle 500 is arranged between the two side plates 322. The diameter of the tool-mounting end 520 of the spindle 500 is smaller than the outer diameter of the cutting ring of the spindle 500, the cutting surface 510 of the spindle 500 is the annular surface of the cutting ring of the spindle 500 facing the pressing block 330, and the cutting ring of the spindle 500 is arranged on the left side of the pressing block 330. When the telescopic pneumatic cylinder 442 drives the spindle 500 to move rightward, the spindle 500 moves rightward relative to the pressing block 330, so that the cutting surface 510 of the spindle 500 abuts against the left side of the pressing block 330. When the spindle 500 continues to move rightward, the pressing block 330 applies leftward pressure to the cutting surface 510 of the spindle 500, so that the spindle 500 is in a state of pressing into the cutting surface 510, and the tool can be inserted into the tool-mounting end 520 of the spindle 500. The tool-mounting end 520 of the spindle 500 is arranged between the two side plates 322, which avoids the situation where the tool cannot be installed due to the fixing component 320 blocking the tool-mounting end 520 of the spindle 500, which can improve the convenience of tool installation and optimize the installation process.

[0061] In an application embodiment, see Figure 1 and Figure 8 The press-in block 330 is provided with an adjustment slot 331, and the side plate 322 is provided with a plurality of adjustment holes. The press-in block 330 is provided on the side plate 322 in a switchable installation position by cooperating with the adjustment slot 331 and the adjustment holes through an adjustment screw. Figure 1 The adjusting through slot 331 is vertically arranged on the front and rear sides of the pressing block 330, including an outer channel and an inner channel. The inner channel is arranged on the side of the pressing block 330 close to the side plate 322. The slot width of the outer channel is greater than the slot width of the inner channel. The screw head of the adjusting screw is arranged in the outer channel and abuts against the bottom wall of the outer channel. The rod body of the adjusting screw passes through the inner channel and is threadedly connected with the adjusting hole of the side plate 322, thereby fixing the connection between the pressing block 330 and the side plate 322. When the adjusting screw is loosened, the adjusting screw is separated from the bottom wall of the outer channel. The abutting position of the adjusting screw and the bottom wall of the outer channel can be adjusted according to the height of the tool-mounting end 520 of the spindle 500, thereby adjusting the connection position of the pressing block 330 and the side plate 322 and adjusting the height of the pressing block 330.
