Description

Technical Field

[0001] This utility model relates to the field of horizontal machining center technology, and in particular to a convenient angle head loading and unloading device for horizontal machining centers. Background Technology

[0002] Horizontal machining centers are suitable for batch processing of parts with complex shapes and high precision requirements, and are one of the hallmark products of the CNC machine tool industry. Their spindles use easily replaceable angle heads, achieving a wide machining range and versatility without altering the machine tool structure. Equipped with a rotatable worktable, they can further enable four-sided machining of a workpiece in a single setup. The required angle heads are typically stored in a tool magazine on the side. However, some large angle heads cannot be stored in the tool magazine due to its limitations. When these angle heads are needed, the operator must manually install them onto the machine spindle. This requires the operator to enter the machine multiple times, which is time-consuming, labor-intensive, affects machining efficiency, and poses safety hazards. Therefore, a convenient loading and unloading device is needed for angle heads that cannot be stored in the tool magazine to solve these problems. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a convenient angle head loading and unloading device for horizontal machining centers that can be used to place the angle head when it is not in use, and can be used in conjunction with the machine tool spindle to complete the loading and unloading of the angle head when the angle head is in use. The device is convenient to load and unload, which helps to reduce the intensity of manual operation and reduce safety hazards.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a convenient angle head loading and unloading device for a horizontal machining center, including a mounting base plate fixedly connected to the worktable of the horizontal machining center, a positioning base slidably mounted on the mounting base plate along the angle head mounting direction, a support structure for placing the angle head on the positioning base, a baffle structure fixedly mounted on the positioning base on the opposite side of the angle head mounting direction, and an elastic force-applying structure between the positioning base and the mounting base plate.

[0005] As a preferred technical solution, the supporting structure includes a first support plate for supporting the speed adjustment part of the angle head and a second support plate for supporting the output end of the angle head's angle shaft part. The top of the first support plate is provided with a first groove, and the top of the second support plate is provided with a second groove.

[0006] As a preferred technical solution, the positioning base is further provided with a supporting protrusion for supporting the bottom of the angular shaft portion between the first support plate and the second support plate.

[0007] As a preferred technical solution, a first height adjuster is provided between the first tray and the positioning base.

[0008] As a preferred technical solution, a second height adjuster is provided between the second tray and the positioning base.

[0009] As a preferred technical solution, the baffle structure includes a baffle seat mounted on the positioning base, and an anti-collision block that can contact the angle head is fixedly provided on the baffle seat.

[0010] As a preferred technical solution, a baffle position adjuster is provided between the baffle base and the positioning base.

[0011] As a preferred technical solution, the installation elastic force-applying structure includes an installation force-applying spring connected between the positioning base and the mounting base plate.

[0012] Due to the adoption of the above technical solution, the horizontal machining center has a convenient angle head loading and unloading device, including a mounting base plate fixedly connected to the worktable of the horizontal machining center. A positioning base is slidably mounted on the mounting base plate along the angle head installation direction. The positioning base is provided with a support structure for placing the angle head. A stop structure is fixedly provided on the positioning base on the opposite side of the angle head installation direction. An elastic force-applying structure is provided between the positioning base and the mounting base plate. This utility model can stably place the angle head by means of the support structure and the lateral limiting of the stop structure when the angle head is not in use. When the angle head is in use, after the angle head is inserted into the machine tool spindle, the machine tool spindle can easily remove the angle head from the support structure and the stop structure by lifting. After use, the angle head can also be easily placed back onto the support structure and the stop structure by lowering. Furthermore, during the loading and unloading process, the installation elastic force-applying structure allows the positioning base to elastically retract, thereby cooperating with the machine tool spindle to complete the loading and unloading of the angle head. This makes loading and unloading convenient, eliminating the need for manual entry into the machine tool for operation, reducing the intensity of manual operation, and minimizing safety hazards.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, exemplary embodiments of the present invention are described only by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, the convenient angle head mounting device for a horizontal machining center includes a mounting base plate 1 fixedly connected to the worktable of the horizontal machining center. Conventionally, the worktable is provided with multiple inverted T-shaped bolt slots, and the mounting base plate 1 is provided with at least two rows of connecting holes 11 according to the spacing of the bolt slots for bolt connection. This bolt connection is easily derived by those skilled in the art based on the description of this embodiment and existing knowledge of worktable tooling fixation, and will not be elaborated further here.

[0020] A positioning base 2 is slidably mounted on the mounting base plate 1 along the mounting direction of the angle head 9. This sliding mounting method can be achieved by using a guide rod sleeve or a guide rail slider, etc. This embodiment illustrates the guide rail slider structure. The positioning base 2 is provided with a support structure 3 for placing the angle head 9. The support structure 3 supports the angle head 9 to achieve placement.

[0021] Among them, the angle head 9 is a well-known technology in the field. Its structure generally includes a speed adjustment part 91 in the middle, a cone head 92 at one end of the speed adjustment part 91, and an angle shaft part 93 at the other end of the speed adjustment part 91. The output shaft of the angle shaft part 93 is used to install the tool, and the cone head 92 is used to insert into the machine tool spindle for center positioning. Of course, the speed adjustment part 91 is usually also provided with a positioning pin 94 for circumferential positioning.

[0022] The supporting structure 3 described in this embodiment includes a first support plate 31 for supporting the speed adjustment part 91 on the angle head 9, and a second support plate 32 for supporting the output end of the angle shaft part 93 on the angle head 9. The top of the first support plate 31 is provided with a first groove 33, and the top of the second support plate 32 is provided with a second groove 34. By supporting the two main parts of the angle head 9 through the two grooves, the angle head 9 is placed on the positioning base 2. The first groove 33 and the second groove 34 are preferably V-shaped or inverted trapezoidal, etc.

[0023] Preferably, the positioning base 2 is further provided with a supporting protrusion 35 for supporting the bottom of the angle shaft portion 93 between the first support plate 31 and the second support plate 32, so as to better support the angle head 9 and improve the stability of the angle head 9.

[0024] Preferably, a first height adjuster 4 is provided between the first support plate 31 and the positioning base 2 to facilitate the first support plate 31 to adaptably support the speed regulating parts 91 with different outer diameters on different models of angle heads 9. Similarly, a second height adjuster 5 is provided between the second support plate 32 and the positioning base 2 to facilitate the second support plate 32 to adaptably support the output shafts of the angle shaft parts 93 with different outer diameters on different models of angle heads 9.

[0025] In this embodiment, the first height adjuster 4 includes a first adjusting bolt 41 threaded onto the positioning base 2 and located below the first support plate 31. The top of the first adjusting bolt 41 abuts against the bottom of the first support plate 31. When the first adjusting bolt 41 is turned, its top end changes height. At this time, it is only necessary to keep the bottom of the first support plate 31 in contact with the top of the first adjusting bolt 41 to adjust the support height of the first support plate 31.

[0026] In this embodiment, the first support plate 31 is bolted to the positioning base 2. Specifically, the positioning base 2 has a first mounting screw hole on the side of the first support plate 31, and a first mounting through hole 42 corresponding to the first mounting screw hole. A first mounting bolt 43 passing through the first mounting through hole 42 is installed in the first mounting screw hole. After adjusting the support height of the first support plate 31, the first support plate 31 can be fixed by tightening the first mounting bolt 43. Since the first support plate 31 has adjustable height, the first mounting through hole 42 is preferably an elongated hole structure with vertically arranged holes.

[0027] Preferably, the positioning base 2 is provided with at least two first guide posts 44 on the side of the first support plate 31. The first guide posts 44 are arranged vertically, and the first support plate 31 is provided with a first guide groove 45 corresponding to the first guide posts 44, so as to guide the vertical adjustment of the first support plate 31 and avoid problems such as the inability to position the angle head 9 during disassembly and assembly caused by the tilt of the first support plate 31.

[0028] Similarly, the second height adjuster 5 also uses a second height adjusting bolt 51 located below the second support plate 32 to achieve height adjustment. The second support plate 32 is also fixed to the positioning base 2 by bolts and is provided with a second guide post 52 and a second guide groove 53 for height adjustment guidance. This is easily derived by those skilled in the art based on the description of the first height adjuster 4 and the accompanying drawings, and will not be elaborated further here.

[0029] A stop structure 6 is fixedly provided on the positioning base 2 on the opposite side of the installation direction of the angle head 9. The stop structure 6 serves two purposes: firstly, it acts as a lateral limit when the angle head 9 is placed; secondly, it acts as a structure to block and apply force to the angle head 9 when it is installed on the machine tool spindle. In this embodiment, the stop structure 6 includes a stop seat 61 installed on the positioning base 2, and a bumper block 62 that can contact the angle head 9 is fixedly provided on the stop seat 61. Conventionally, the bumper block 62 can be made of materials such as nylon or rubber.

[0030] Since different models of angle heads 9 have different external dimensions, a stop position adjuster 7 is also provided between the stop base 61 and the positioning base 2 in this embodiment to accommodate different external dimensions. The stop position adjuster 7 in this embodiment includes a stop mounting screw hole provided on the positioning base 2. The stop base 61 is provided with a stop mounting through hole 71 corresponding to the stop mounting screw hole. The stop mounting through hole 71 is an elongated hole along the direction close to or away from the angle head 9. A stop mounting bolt 72 is installed on the stop mounting screw hole, passing through the stop mounting through hole 71.

[0031] An elastic force-applying structure 8 is provided between the positioning base 2 and the mounting base plate 1. The elastic force-applying structure 8 is slidably installed with the positioning base 2, so that when the angle head 9 is installed on the machine tool spindle, it will not cause damage to the angle head 9 or the machine tool spindle structure due to rigid pressure, and it can provide an elastic force for the angle head 9 to be installed on the machine tool spindle, ensuring that the angle head 9 is installed in place.

[0032] The installation elastic force-applying structure 8 includes an installation force-applying spring 81 connected between the positioning base 2 and the mounting base plate 1. In specific use, in this embodiment, force-applying seats 82 are respectively fixedly installed on the positioning base 2 and the mounting base plate 1. Force-applying guide rods 83 are installed through the two force-applying seats 82. Force-applying limiting stops 84 are respectively provided on the force-applying guide rods 83 on the outer side of the two force-applying seats 82. The installation force-applying spring 81 is fitted on the force-applying guide rods 83 between the two force-applying seats 82.

[0033] In this embodiment, the mounting base plate 1 is fixedly connected to a certain position on the workbench according to the assembly and disassembly requirements of the angle head 9. When the angle head 9 is placed on the positioning base 2, the supporting effect of the first support plate 31 on the speed adjustment part 91, the supporting effect of the second support plate 32 on the output end of the diagonal shaft part 93, the supporting effect of the supporting protrusion 35 on the bottom of the diagonal shaft part 93, and the lateral limiting effect of the stop structure 6 ensure that the angle head 9 can be stably placed on the positioning base 2 in the required posture. Of course, preferably, the supporting height is adjusted by the first height adjuster 4 and the second height adjuster 5, and if necessary, the supporting protrusion 35 of different height dimensions is also replaced so that after the angle head 9 is placed on the positioning base 2, the axis of the cone head 92 of the angle head 9 is at the required height.

[0034] When the angle head 9 is needed, the machine spindle moves to a height where its axis coincides with the axis of the angle head 9's cone 92. The worktable begins to feed towards the machine spindle, and the angle head 9's cone 92 inserts into the machine spindle's tapered hole. Under the reaction force of the machine spindle, the positioning base 2 compresses the mounting elastic force-applying structure 8, causing a slight retraction. The elastic force generated by the mounting elastic force-applying structure 8 also allows the angle head 9 to form a good insertion with the machine spindle. After the angle head 9 is clamped onto the machine spindle, the machine spindle rises, and the angle head 9 can be easily removed from the support structure 3. After removal, the positioning base 2 returns to its original position under the action of the mounting elastic force-applying structure 8.

[0035] After the angle head 9 is used, the machine tool spindle reverses the action of picking up the angle head 9, lowering the angle head 9 onto the support structure 3. The angle head 9 presses against the stop structure 6, causing the positioning base 2 to compress the mounting elastic force-applying structure 8 and slightly retract. The angle head 9 is ultimately held in place on the positioning base 2 by the support structure 3 and the stop structure 6, forming a stable position in the required posture. At this time, the machine tool spindle removes the clamping of the angle head 9, and the tool-removing cylinder on the machine tool knocks the angle head 9 away from the machine tool spindle. During this process, the positioning base 2 further compresses the mounting elastic force-applying structure 8 to retract. Afterward, the worktable moves the positioning base 2 away from the machine tool spindle, and the positioning base 2 returns to its original position under the action of the mounting elastic force-applying structure 8. The angle head 9 loading and unloading operation is completed in one go.

[0036] In this embodiment, the angle head 9 can be stably placed by the support of the support structure 3 and the lateral limiting of the stop structure 6 when the angle head 9 is not in use. When the angle head 9 is in use, it can be loaded and unloaded in conjunction with the machine tool spindle. The loading and unloading is convenient and does not require manual operation, which helps to reduce the intensity of manual operation and reduce safety hazards.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
