Description

Technical Field

[0001] This utility model relates to the field of machine tool processing technology, specifically to a linear end-driven machine tool magazine. Background Technology

[0002] A linear end-driven machine tool magazine is a technical device used in CNC machining centers. Its characteristic is that it uses a linear end-driven method to realize the movement of the machine tool tool holder module and the tool changing operation. The device mainly includes the tool magazine body, motor, output gear and drive chain. The motor drives the output gear to rotate. The output gear has a wide tooth profile and meshes with the chain links of the drive chain to drive the chain to move linearly. The tool holder module is set on the chain for clamping and changing tools.

[0003] Chinese patent CN222711596U discloses a linear end-driven machine tool magazine, comprising a magazine body, a motor, an output gear, and a drive chain. The output gear has a wide-tooth profile, and the links of the drive chain have drive holes corresponding to the teeth of the output gear, with the teeth of the output gear meshing in the drive holes. By using a wide-tooth output gear and engaging with the links of the drive chain, the strength of the gear teeth and the torque are increased, thus effectively driving the links and moving the tool holder modules mounted on them. Because the driving effect on the links is more stable, the motor can be positioned at any edge of the magazine body to drive the links. This allows the motor to be adjusted according to the location of different mechanisms, avoiding interference with other mechanisms and increasing the freedom of motor placement.

[0004] However, the machine tool magazine is mounted on the machine tool housing via a fixed base plate. The machine tool magazine needs to be replaced during use, which requires removing multiple four-corner bolts on the fixed base plate. This operation is cumbersome, time-consuming, and labor-intensive. Furthermore, because the machine tool magazine itself is quite heavy, there is a risk of the machine tool magazine tipping over when removing the four-corner bolts at one end. Therefore, there is a need to provide a machine tool magazine with linear end drive. Utility Model Content

[0005] The purpose of this invention is to provide a linear end-driven machine tool magazine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a linear end-driven machine tool magazine, comprising a mounting base, a bearing bracket, a machine tool magazine body, and a hanging plate. The bearing bracket and the hanging plate are provided with a fixing mechanism. The fixing mechanism includes a slot on the hanging plate, a telescopic groove on the bearing bracket, a wedge-shaped block slidably disposed within the telescopic groove and engaging with the slot, the hanging plate and the wedge-shaped block slidingly contacting each other through a pressing mechanism, limit blocks fixedly disposed at both ends of the wedge-shaped block, a limit groove within the telescopic groove, the limit blocks slidably connected to the limit groove, and a spring fixedly disposed within the telescopic groove and fixedly connected to the wedge-shaped block. A winding cavity is provided within the bearing bracket, a rotating rod rotatably disposed within the winding cavity, a winding wheel fixedly sleeved on the rotating rod, a hand-tightening block fixedly connected to the top of the rotating rod rotatably passing through the winding cavity, and a connecting rope wound around the winding wheel. The free end of the connecting rope passes through the winding cavity and extends into the telescopic groove to connect with the wedge-shaped block.

[0007] Preferably, the hanging plate has an arc-shaped groove, and arc-shaped blocks are fixedly installed at both ends of the bearing bracket, with the arc-shaped groove and the arc-shaped blocks being slidably connected.

[0008] Preferably, the bearing bracket has an insertion groove, and the hanging plate is slidably connected to the insertion groove.

[0009] Preferably, the bearing bracket is fixedly mounted on the mounting base plate, and the mounting plate is fixedly mounted on one side of the machine tool magazine body.

[0010] Preferably, the mounting plate and the load-bearing bracket are engaged in a snap-fit ​​manner.

[0011] Preferably, both the mounting base plate and the bearing bracket are provided with fixing holes for fixing the mounting base plate and the bearing bracket.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1) This linear end-driven machine tool magazine rotates by turning the hand-tightening block, which causes the rotating rod to drive the winding wheel to rotate. When the winding wheel rotates, it can wind up the connecting rope, so that the wedge-shaped locking block connected to the connecting rope can be pulled away from the locking groove by the tension of the connecting rope and retract into the telescopic groove. Then, the machine tool magazine body is lifted upward, so that the hanging plate is detached from the bearing bracket, which can complete the quick disassembly of the machine tool magazine body and facilitate the replacement of the machine tool magazine body according to actual needs.

[0014] 2) This linear end-driven machine tool magazine works by sliding the mounting plate into the bearing bracket. When the mounting plate is inserted, it can compress the inclined surface of the wedge-shaped block, causing the wedge-shaped block to be compressed and retract into the telescopic groove under the limit of the limit block and the limit groove. At this time, the spring is compressed by the wedge-shaped block. When the mounting plate is fully inserted into the bearing bracket, the wedge-shaped block is aligned with the slot on the mounting plate. Under the spring's rebound, the wedge-shaped block automatically pops out and engages with the slot, thus locking the mounting plate onto the bearing bracket. The operation is simple and convenient, facilitating the quick installation of the machine tool magazine body. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Combination Figures 1-6 A linear end-driven machine tool magazine includes a mounting base plate 1, a bearing bracket 3, a machine tool magazine body 4, and a hanging plate 5. The bearing bracket 3 is fixedly mounted on the mounting base plate 1, and the hanging plate 5 is fixedly mounted on one side of the machine tool magazine body 4. The hanging plate 5 and the bearing bracket 3 are fitted together. The mounting base plate 1 and the bearing bracket 3 are both provided with fixing holes 2 for fixing the mounting base plate 1 and the bearing bracket 3. The bearing bracket 3 and the hanging plate 5 are provided with fixing mechanisms 6.

[0026] See Figures 3-6 Furthermore, the fixing mechanism 6 includes a slot 62 on the hanging plate 5, a telescopic groove 65 on the bearing bracket 3, a wedge-shaped block 66 that engages with the slot 62 slidably disposed within the telescopic groove 65, the hanging plate 5 and the wedge-shaped block 66 making a squeezing sliding contact, limit blocks 67 fixedly disposed at both ends of the wedge-shaped block 66, a limit groove 68 disposed within the telescopic groove 65, the limit blocks 67 and the limit groove 68 being slidably connected, and a wedge-shaped block 66 being fixedly disposed within the telescopic groove 65. 6. A fixedly connected spring 69; a winding cavity 610 is provided in the bearing bracket 3, a rotating rod 611 is rotatably arranged in the winding cavity 610, a winding wheel 612 is fixedly sleeved on the rotating rod 611, the top of the rotating rod 611 rotatably passes through the winding cavity 610 and is fixedly connected to a hand-tightening block 613, a connecting rope 614 is wound on the winding wheel 612, the free end of the connecting rope 614 passes through the winding cavity 610 and extends into the telescopic groove 65 to connect with the wedge-shaped locking block 66.

[0027] Specifically, by rotating the hand-tightening block 613, the rotating rod 611 drives the winding wheel 612 to rotate. When the winding wheel 612 rotates, it can wind up the connecting rope 614, so that the wedge-shaped locking block 66 connected to the connecting rope 614 can be pulled away from the locking groove 62 by the tension of the connecting rope 614 and retract into the telescopic groove 65. Then, the machine tool magazine body 4 is lifted upward, so that the hanging plate 5 is detached from the bearing bracket 3, thus completing the quick disassembly of the machine tool magazine body 4, which is convenient for replacing the machine tool magazine body 4 according to actual needs.

[0028] See Figure 3 and Figure 4 Furthermore, the hanging plate 5 has an arc-shaped groove 61, and the two ends of the bearing bracket 3 are fixedly installed with arc-shaped blocks 63. The arc-shaped groove 61 and the arc-shaped blocks 63 are slidably connected. The bearing bracket 3 has an insertion groove 64, and the hanging plate 5 is slidably connected with the insertion groove 64.

[0029] Specifically, by sliding the hanging plate 5 into the bearing bracket 3, when the hanging plate 5 is inserted from the top of the bearing bracket 3, the insertion groove 64 opened at the top of the bearing bracket 3 can make it easier for the hanging plate 5 to be inserted into the bearing bracket 3. The arc groove 61 opened in the hanging plate 5 can slide with the arc blocks 63 set at both ends of the bearing bracket 3 to limit the movement, thereby improving the smoothness of the hanging plate 5 being inserted into the bearing bracket 3.

[0030] In actual operation, the mounting base plate 1 and the bearing bracket 3 are fixedly installed on the machine tool housing using bolts and fixing holes 2. Then, the mounting plate 5 is slidably inserted into the bearing bracket 3. When the mounting plate 5 is inserted from the top of the bearing bracket 3, the insertion groove 64 on the top of the bearing bracket 3 allows the mounting plate 5 to be inserted into the bearing bracket 3 more conveniently. The arc-shaped groove 61 inside the mounting plate 5 can slide against the arc-shaped blocks 63 at both ends of the bearing bracket 3, improving the smoothness of the mounting plate 5 when it is inserted into the bearing bracket 3. The inclined surface of the wedge-shaped locking block 66 is squeezed, causing the wedge-shaped locking block 66 to be squeezed and retracted into the telescopic groove 65 under the limit of the limiting block 67 and the limiting groove 68. At this time, the spring 69 is compressed by the wedge-shaped locking block 66. When the hanging plate 5 is fully inserted into the bearing bracket 3, the wedge-shaped locking block 66 is aligned with the slot 62 on the hanging plate 5. Under the rebound of the spring 69, the wedge-shaped locking block 66 automatically pops out and engages with the slot 62, thereby locking the hanging plate 5 onto the bearing bracket 3 and completing the installation of the machine tool magazine body 4.

[0031] When the machine tool magazine body 4 needs to be replaced, rotate the hand-tightening block 613 to drive the rotating rod 611 to rotate the winding wheel 612. When the winding wheel 612 rotates, it can wind up the connecting rope 614, so that the wedge-shaped locking block 66 connected to the connecting rope 614 can be disengaged from the locking groove 62 by the tension of the connecting rope 614 and retract into the telescopic groove 65. Then, lift the machine tool magazine body 4 upward to disengage the hanging plate 5 from the bearing bracket 3, thus completing the quick disassembly of the machine tool magazine body 4. After replacing the required machine tool magazine body 4, install it again according to the installation operation of the machine tool magazine body 4.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
