Description

Technical Field

[0001] This application relates to the field of CNC machine tool technology, and more specifically to an angle head mounting bracket. Background Technology

[0002] CNC machine tool spindles can mount tools individually or via angle heads, thus requiring frequent angle head replacements. Replaced angle heads need to be placed on an angle head holder. Existing angle head holders typically consist of a support body and a top cover. The top of the support body has an angle head receiving cavity for storing the angle heads, and the top cover is placed on top of the support body to close the angle head receiving cavity. The top cover can move upwards relative to the support body to open the angle head receiving cavity.

[0003] In existing angle head holders, the gap between the angle head placed in the angle head receiving cavity and the side wall of the angle head receiving cavity is narrow, which makes it inconvenient to pick up and put down the angle head.

[0004] Therefore, how to provide an angle head placement rack to improve the convenience of angle head retrieval remains a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, to solve the above-mentioned technical problems, this application provides an angle head placement bracket for placing angle heads. The angle head includes a base, a transmission head, and an extension head, with the transmission head and extension head protruding from both sides of the base. The angle head placement bracket includes:

[0006] The support body has an extension head receiving cavity at its top for accommodating the extension head.

[0007] A base support is provided at the top of the extension head receiving cavity to support the base; the base support is provided with an extension head clearance opening to avoid the extension head.

[0008] The chip-blocking side plate is provided on the outside of the base support and extends upward;

[0009] The top cover is detachable and mounted on the base support. The top cover, base support, and chip-blocking side plate together form a transmission head receiving cavity for accommodating the transmission head.

[0010] The top cover can be moved to the first side to expose the transmission head and the base. The first side is the side of the transmission head accommodating cavity that faces away from the chip-blocking side plate.

[0011] Beneficial effects: Unlike existing technologies, in this application, the top cover is moved to the first side, and can be opened by pulling it to the first side to expose the angle head. The first side is the side of the transmission head accommodating cavity facing away from the chip-blocking side plate. Compared to the existing method of pulling the top cover upwards to open it, the method of pulling the top cover to the first side in this application requires less effort. Furthermore, after opening the top cover, the space above the base support is exposed to the outside, exposing the transmission head and the base, thus facilitating the placement and removal of the angle head.

Detailed Implementation

[0027] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] Please see Figures 1-5 The angle head holder 10 of this application is used to hold the angle head 20, which includes a base 21, a transmission head 22, and an extension head 23. The transmission head 22 and the extension head 23 are respectively protruding from both sides of the base 21. The transmission head 22 is used for transmission connection with the spindle (not shown), and the extension head 23 is provided with a tool mounting groove 23-1 for mounting tools (not shown).

[0029] It should be noted that the tool can be mounted on the spindle using either the first method or the second method. The first method involves mounting the tool directly on the spindle. The second method involves first mounting the angle head 20 on the spindle, and then mounting the tool in the tool mounting slot 23-1 of the angle head 20. When the angle head 20 is not needed or needs to be replaced, it must first be removed and stored in the angle head holder 10.

[0030] like Figures 1-4 As shown, the angle head placement rack 10 of this application includes a support body 100, a base support 200, a chip-blocking side plate 300, and a top cover 400.

[0031] The top of the support body 100 is provided with an extension head receiving cavity 101 for accommodating the extension head 23. A base support portion 200 is disposed at the top of the extension head receiving cavity 101 for supporting the base 21. The base support portion 200 is provided with an extension head clearance opening 201 to avoid the extension head 23. A chip-blocking side plate 300 is disposed on the outside of the base support portion 200 and extends upward. A top cover 400 is detachably disposed on the base support portion 200. The top cover 400, the base support portion 200, and the chip-blocking side plate 300 enclose a transmission head receiving cavity 11 for accommodating the transmission head 22. The top cover 400 is movable to a first side to expose the transmission head 22 and the base 21; the first side is the side of the transmission head receiving cavity 11 facing away from the chip-blocking side plate 300.

[0032] In this way, by moving the top cover 400 to the first side and pulling it out, the angle head 20 can be exposed. The first side is the side of the transmission head receiving cavity 11 facing away from the chip-blocking side plate 300. Compared to the prior art method of pulling the top cover 400 upwards to open it, the method of pulling the top cover 400 outwards in this application requires less effort. Furthermore, after opening the top cover 400, the space above the base support 200 is exposed to the outside, exposing the transmission head 22 and the base 21, thereby facilitating the placement and removal of the angle head 20.

[0033] Optionally, combined Figures 1-3 See Figure 6 As shown, the angle head placement bracket 10 includes a first limiting member 510 and a second limiting member 520. The first limiting member 510 is disposed on the top cover 400, and the second limiting member 520 is disposed on the bracket body 100.

[0034] The first limiting member 510 and the second limiting member 520 are in a locking state to prevent the top cover 400 from moving to the first side. The first limiting member 510 and the second limiting member 520 are in a separating state to allow the top cover 400 to move to the first side.

[0035] In this manner, when the top cover 400 is closed onto the base support 200, the first limiting member 510 and the second limiting member 520 can be placed in a blocking state to prevent the top cover 400 from moving to the first side, thus preventing accidental opening of the top cover 400. When it is necessary to remove the angle head 20, the first limiting member 510 and the second limiting member 520 can be placed in a separated state, and then the top cover 400 can be moved to the first side to open the top cover 400 by pulling it open, thereby exposing the base 21 and the transmission head 22 and facilitating the removal of the angle head 20.

[0036] Optionally, combined Figures 1-3 See Figure 6 As shown, the blocking state can be at least one of the following: plug-in engagement, hook engagement, threaded engagement, and magnetic attraction engagement between the first limiting member 510 and the second limiting member 520. By adjusting the first limiting member 510 or the second limiting member 520, the blocking state can be released, causing the first limiting member 510 and the second limiting member 520 to switch to a separated state.

[0037] For example, rather than limiting, in combination Figures 1-3 See Figure 6 As shown, one of the first limiting member 510 and the second limiting member 520 can be a spring pin, and the other can be a socket with a socket hole. The spring pin engages with the socket hole to keep the first limiting member 510 and the second limiting member 520 in a locked state. The spring pin disengages from the socket hole to separate the first limiting member 510 and the second limiting member 520.

[0038] Optionally, in combination with 1- Figure 5 See Figure 7 As shown, the top cover 400 has a transmission head receiving groove 401 and a transmission head clearance opening 402 on the side facing the base support 200.

[0039] The transmission head receiving groove 401 is used to receive the transmission head 22, and the transmission head clearance opening 402 is provided on the side wall of the transmission head receiving groove 401. The chip-blocking side plate 300 covers the transmission head clearance opening 402, so that the top cover 400, the base support 200 and the chip-blocking side plate 300 form the transmission head receiving cavity 11. The transmission head clearance opening 402 is used to avoid the transmission head 22, so that the top cover 400 can move to the first side to expose the transmission head 22 and the base 21.

[0040] Optionally, combined Figures 1-5 See Figures 6-8As shown, the outer side of the extension head clearance opening 201 has a first side 202 and a second side 203 that are oppositely disposed and adjacent to the chip-blocking side plate 300. The top end of the extension head receiving cavity 101 is provided with a first inclined plate portion 610 on the first side 202 and the second side 203, respectively. The base support portion 200 is located between the first inclined plate portion 610 of the first side 202 and the first inclined plate portion 610 of the second side 203. The end of the transmission head receiving groove 401 facing the base support portion 200 is provided with a second inclined plate portion 620 corresponding to the first side 202 and the second side 203, respectively.

[0041] The second inclined plate portion 620 is located above the first inclined plate portion 610 and is used for guiding cooperation with the second inclined plate portion 620 to guide the top cover 400 to perform a first movement or a second movement. The first movement is the top cover 400 moving to a first side, and the second movement is the top cover 400 moving to a second side, where the second side is the side of the transmission head receiving cavity 11 facing away from the base support portion 200.

[0042] By means of the above method, the top cover 400 can be opened by guiding the second inclined plate portion 620 and the first inclined plate portion 610 to make a first or second movement, thereby providing a variety of ways to open the top cover 400.

[0043] It should be noted that during the process of closing the top cover 400, when the second inclined plate portion 620 contacts the first inclined plate portion 610 and the top cover 400 continues to move toward the side of the transmission head receiving groove 401 toward the base support portion 200, the first inclined plate portion 610 can guide and cooperate with the second inclined plate portion 620 to guide the top cover 400 to accurately close onto the base support portion 200.

[0044] It is understood that in other embodiments, the second movement capability of the top cover 400 may be sacrificed while retaining the first movement capability. For example, one of the second inclined plate portion 620 and the first inclined plate portion 610 may be replaced by a slide rail, and the other may be replaced by a slider, with the slide rail and slider providing a guiding engagement to guide the top cover 400 to perform the first movement.

[0045] Optionally, combined Figures 1-5 See Figures 6-8 As shown, the outer side of the extension head clearance opening 201 has a third side 204 opposite to the chip baffle plate. A third inclined plate portion 630 is provided at one end of the transmission head receiving groove 401 facing the base support portion 200, corresponding to the third side 204. The base support portion 200 is located between the third inclined plate portion 630 of the third side 204 and the chip baffle plate 300. A fourth inclined plate portion 640 is provided at the top of the extension head receiving cavity 101 on the third side 204.

[0046] The third inclined plate portion 630 is located above the fourth inclined plate portion 640 and is guided and cooperated with the fourth inclined plate portion 640 to guide the top cover 400 to make a second movement. The second movement is the top cover 400 moving to a second side, which is the side of the transmission head accommodating cavity 11 facing away from the base support portion 200.

[0047] In the above manner, during the process of closing the top cover 400, when the second inclined plate portion 620 contacts the first inclined plate portion 610 and the third inclined plate portion 630 contacts the fourth inclined plate portion 640, and the top cover 400 continues to move towards the side of the transmission head receiving groove 401 toward the base support portion 200, the first inclined plate portion 610 can guide and cooperate with the second inclined plate portion 620 and the third inclined plate portion 630 can guide and cooperate with the fourth inclined plate portion 640, so as to guide the top cover 400 to accurately close onto the base support portion 200.

[0048] Optionally, combined Figures 1-5 See Figures 6-8 As shown, the top of the extension head receiving cavity 101 is provided with a first top cover support 710 on the first side 202 and the second side 203 respectively. The first top cover support 710 is located on the side of the first inclined plate 610 away from the extension head clearance opening 201.

[0049] The transmission head receiving groove 401 has a first abutting part 720 at one end facing the base support part 200, corresponding to the first side 202 and the second side 203, respectively. The first abutting part 720 abuts against the first top cover support part 710. The second inclined plate part 620 is provided on the first abutting part 720.

[0050] By means of the above method, the first abutting part 720 abuts against the first top cover support part 710, and the first inclined plate part 610 and the second inclined plate part 620 are guided and engaged, which can more stably support the top cover 400.

[0051] Optionally, combined Figures 1-5 See Figures 6-8 As shown, a second top cover support 730 is provided at the top of the extension head receiving cavity 101 on the third side 204. The second top cover support 730 is located on the side of the third inclined plate 630 opposite to the extension head clearance opening 201.

[0052] The transmission head receiving groove 401 has a second abutting part 740 at one end facing the base support part 200, corresponding to the third side 204. The second abutting part 740 abuts against the second top cover support part 730. The fourth inclined plate part 640 is provided at the second abutting part 740.

[0053] By means of the above method, the first abutting part 720 abuts against the first top cover support part 710, and the first inclined plate part 610 and the second inclined plate part 620 are guided and engaged, the second abutting part 740 abuts against the second top cover support part 730, and the third inclined plate part 630 and the fourth inclined plate part 640 are guided and engaged, the top cover 400 can be supported more stably.

[0054] Optionally, combined Figures 1-5 See Figures 6-8 As shown, a protruding protrusion 410 is provided on the inner sidewall of the transmission head receiving groove 401, and an upwardly extending inclined groove 411 is provided on the outer sidewall of the transmission head receiving groove 401. The upwardly extending inclined groove 411 extends obliquely upward into the protrusion 410, so that the upper sidewall of the upwardly extending inclined groove 411 forms a handle 412. In this way, the handle 412 can be easily gripped for pulling out the top cover 400.

[0055] It should be noted that the handle 412 is not limited to Figure 7 The style shown, namely the handle 412, can be adopted in other examples using existing common handle 412.

[0056] To facilitate the handling and placement of the angle head 20, combined with Figures 1-4 See Figure 9 As shown, the angle head holder 10 can be placed next to the machine base (not shown) of a CNC machine tool (not shown). At this time, considering that when the top cover 400 is closed on the base support 200, there may still be a gap (not shown) between the top cover 400 and the chip-blocking side plate 300, the chips generated by the workpiece on the CNC machine tool processing table can easily fall into the transmission head receiving cavity 11 through this gap.

[0057] Therefore, optionally, in combination Figures 1-4 See Figure 9 As shown, a chip collecting member 310 is provided on the side of the chip-blocking side plate 300 facing the transmission head receiving cavity 11. The chip collecting member 310 is provided with a chip collecting groove 311, which is used to collect the chips that fall along the chip-blocking side of the chip-blocking plate towards the transmission head receiving cavity 11. This can prevent chips from scattering on the angle head 20 or on the base support 200.

[0058] Optionally, combined Figures 1-4 See Figure 9As shown, the chip collection trough 311 includes an upper chip collection trough 312 and a side chip collection trough 313. The upper chip collection trough 312 is disposed on the upper side of the chip collection member 310 and extends along the chip-blocking side plate 300. The side chip collection trough 313 is disposed on the side wall of the chip collection member 310 and is adjacent to the chip-blocking side plate 300 and communicates with the upper chip collection trough 312. The portion of the side wall of the transmission head receiving groove 401 opposite to the side chip collection trough 313 covers the side chip collection trough 313. Thus, after the top cover 400 is opened, the debris collected in the upper chip collection trough 312 can be swept into the side chip collection trough 313, and then swept away along with the debris in the side chip collection trough 313.

[0059] In this embodiment, the upper chip collection trough 312 and the side chip collection trough 313 can be integrally disposed on the chip collection member 310, but are not limited thereto. It should be noted that in other examples, the side chip collection trough 313 can be configured to be detachably disposed on the chip collection member 310, so that after opening the top cover 400 and sweeping the debris in the upper chip collection trough 312 into the side chip collection trough 313, the side chip collection trough 313 can be removed to empty the debris.

[0060] Optionally, such as Figure 4 , Figure 10 and Figure 13 As shown, an alignment device 800 is provided at the bottom end of the extension head receiving cavity 101. The alignment device 800 is used to extend into the tool mounting groove 23-1 to radially limit the extension head 23. This prevents the angle head 20 from wobbling radially in the tool mounting groove 23-1.

[0061] Optionally, such as Figure 4 , Figure 10 and Figure 13 As shown, the portion of the head-aligning device 800 that extends into the tool mounting slot 23-1 can be formed with a shape that gradually narrows from bottom to top, so that the head-aligning device 800 can be inserted into the tool mounting slot 23-1 to radially limit the extension head 23.

[0062] Optionally, combined Figures 1-3 See Figure 6 and Figure 12 As shown, the base 21 is provided with a limiting hole 21-1, and the base support 200 is provided with a positioning pin 210. The positioning pin 210 is inserted into the limiting hole 21-1 to circumferentially limit the base 21. This prevents the angle head 20 from rotating circumferentially in the tool mounting groove 23-1.

[0063] Optionally, combined Figures 1-3 See Figure 6As shown, the angle head mounting bracket 10 includes a sensor bracket 220, which is disposed on the base support portion 200. The sensor bracket 220 is used to mount a sensor (not shown in the figure), and the sensor is used to detect whether the angle head 20 is installed in place. The sensor can be one or more of optical sensors, ultrasonic sensors, contact sensors, and proximity sensors, but is not limited to these.

[0064] Optionally, combined Figures 1-3 See Figure 6 and Figure 12 As shown, the base support portion 200 is provided with a plurality of support members 230, which are distributed around the extension head clearance opening 201. Each support member 230 includes a rod portion 231 and a support head 232. The rod portion 231 is vertically adjustable and disposed on the base support portion 200, and the support head 232 is disposed at the upper end of the rod portion 231 to support the base 21. For example, and not as a limitation, the rod portion 231 is threadedly connected to the base support portion 200 so that the rod portion 231 is vertically adjustable on the base support portion 200.

[0065] In this way, the top surfaces of the support heads 232 of the multiple support members 230 can all abut against the base 21 by adjusting the rod 231 up and down, so as to stabilize the support angle head 20.

[0066] Optionally, combined Figures 1-12 See Figure 13 As shown, the support body 100 includes a frame 110, an upper cavity shell 120, and a lower cavity shell 130. The upper cavity shell 120 is disposed at the upper end of the frame 110, and the lower cavity shell 130 is disposed on the frame 110 and located below the upper cavity shell 120. The lower cavity shell 130 and the upper cavity shell 120 are separately disposed.

[0067] An extension head receiving cavity 101 is formed within the upper cavity housing 120. A base support portion 200 is disposed within the frame body 110. A first inclined plate portion 610, a first top cover support portion 710, a third inclined plate portion 630, a second top cover support portion 730, and an alignment device 800 are disposed within the frame body 110. A cavity 132 is formed within the lower cavity housing 130.

[0068] By means of the above method, the separate arrangement of the upper cavity shell 120 and the lower cavity shell 130 facilitates the installation of the upper cavity shell 120 and the lower cavity shell 130 on the frame body 110.

[0069] Optionally, the upper cavity shell 120 is fitted onto the upper end of the frame body 110, and the upper cavity shell 120 is integrally formed, but is not limited thereto. This facilitates the installation of the upper cavity shell 120 on the frame body 110. Optionally, the lower cavity shell 130 includes a plurality of separately arranged surrounding pieces 131 disposed on the outside of the frame body 110, which facilitates the installation of the lower cavity shell 130 on the frame body 110.

[0070] Optionally, combined Figures 1-4 As shown, a window plate 121 is provided on the side wall of the upper cavity housing 120. The window plate 121 is used to transmit light to expose the view inside the extension head receiving cavity 101 to the outside of the upper cavity housing 120, so as to facilitate viewing whether the angle head 20 is aligned with the head aligner 800.

[0071] Optionally, such as Figure 13 As shown, the main body 100 of the support includes a base 910, a foot 920, and a reinforcing rod 930. The frame body 110 is disposed on the base 910. The base 910 is provided with the foot 920 and the reinforcing rod 930. The foot 920 extends at least partially below the base 910 to support the base 910. The reinforcing rod 930 connects to the frame body 110 and forms a triangular space 901 between the reinforcing rod 930 and the frame body 110 to improve the rigidity of the frame body 110 and avoid or reduce the deformation of the frame body 110.
