Description

Technical Field

[0001] This utility model relates to the technical field of CNC machining, and in particular to a CNC machining fixture and clamping assembly for a speaker handle. Background Technology

[0002] A speaker handle is a speaker component. Specifically, the speaker handle includes an arc-shaped rod and two bosses. The two bosses are respectively located at both ends of the arc-shaped rod, and the bosses protrude in the direction of the curvature of the arc-shaped rod. There are also two protruding posts on the bosses.

[0003] Because the speaker handle is not flat, existing machining fixtures require a long time for positioning and clamping when clamping the speaker handle, resulting in long downtime for equipment clamping and affecting processing efficiency. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a CNC machining fixture for speaker handles, which can improve clamping efficiency on equipment and reduce equipment downtime for clamping.

[0005] This utility model also proposes a clamping assembly having the above-mentioned CNC machining fixture for speaker handles.

[0006] A CNC machining fixture for a speaker handle according to a first aspect embodiment of the present invention includes:

[0007] The first clamping mechanism is used to clamp the speaker handle;

[0008] The second clamping mechanism is installed on the processing equipment and is used to clamp the first clamping mechanism. The first clamping mechanism and the second clamping mechanism are detachably connected.

[0009] A CNC machining fixture for a speaker handle according to an embodiment of the present utility model has at least the following beneficial effects:

[0010] This invention features a first clamping mechanism and a second clamping mechanism. The first clamping mechanism clamps the speaker handle, while the second clamping mechanism, mounted on the processing equipment, clamps the first clamping mechanism. The first and second clamping mechanisms are detachably connected. This allows the operator to pre-position and clamp the speaker handle onto the first clamping mechanism outside the equipment. When the equipment stops, the entire first clamping mechanism can be quickly transferred to the second clamping mechanism. This enables the operator to simultaneously position the speaker handle to be processed onto the first clamping mechanism outside the equipment while processing another set of handles, avoiding the need to position and clamp uneven handles when the equipment stops. This improves the clamping efficiency of the speaker handles on the equipment, significantly reduces equipment downtime for clamping, and enhances processing efficiency.

[0011] According to some embodiments of the present invention, the first clamping mechanism includes a first pressing component, a second pressing component, and a connecting component. The first pressing component and the second pressing component cooperate to clamp the speaker handle, and the connecting component is used to detachably connect the first pressing component and the second pressing component.

[0012] The advantages of this invention are that the first clamping mechanism includes a first clamping component, a second clamping component, and a connecting component. The first and second clamping components work together to clamp the speaker handle, and the connecting component is used to detachably connect the first and second clamping components. It can be understood that the separate clamping structure of the first and second clamping components can adapt to the complex curved shape of the speaker handle. In addition, the detachable design of the connecting component makes the clamp more flexible to install and remove, and facilitates the fixing and loosening of the speaker handle by the first and second clamping components.

[0013] According to some embodiments of the present invention, the first pressing component includes a first contour block, the second pressing component includes a second contour block, and the first contour block and the second contour block abut against and clamp the speaker handle.

[0014] The advantages of this invention are: by having the first clamping component include a first contour block and the second clamping component include a second contour block, with the first and second contour blocks abutting and clamping the speaker handle, it can be understood that the first and second contour blocks are highly fitted to the surface of the speaker handle, which can improve clamping stability, reduce processing vibration caused by loose clamping, and improve processing accuracy and surface quality.

[0015] According to some embodiments of the present invention, the first clamping assembly includes a first support base, and the first contour block is disposed on the first support base; the second clamping assembly includes a second support base, and the second contour block is disposed on the second support base; the connecting assembly includes a connecting column and at least one fixing bolt; one end of the connecting column is fixedly connected to one of the first support base and the second support base, and the other end of the connecting column is detachably connected to the other of the first support base and the second support base by the fixing bolt, or, both ends of the connecting column are detachably connected to the first support base and the second support base respectively by the fixing bolt.

[0016] The advantages of this invention are as follows: The first clamping assembly includes a first support base, and a first contour block is disposed on the first support base; the second clamping assembly includes a second support base, and a second contour block is disposed on the second support base; the connecting assembly includes a connecting column and at least one fixing bolt; one end of the connecting column is fixedly connected to one of the first and second support bases, and the other end of the connecting column is detachably connected to the other of the first and second support bases via a fixing bolt; or, both ends of the connecting column are detachably connected to the first and second support bases respectively via fixing bolts. It is understood that, on the one hand, the rigid connection structure between the connecting column and the first and second support bases ensures a uniform distribution of clamping force; on the other hand, the fixing bolt connection method ensures connection strength while facilitating quick assembly and disassembly, reducing operational complexity.

[0017] According to some embodiments of this utility model, two first contour blocks are provided, and two corresponding second contour blocks are provided. The two first contour blocks cooperate with the two second contour blocks to clamp the two positions of the speaker handle.

[0018] The advantage of this invention is that by setting two first contour blocks and two corresponding second contour blocks, the two first contour blocks cooperate with the two second contour blocks to clamp the two positions of the speaker handle. It can be understood that the dual clamping design of the two sets of first and second contour blocks can achieve synchronous clamping and positioning of the two positions of the speaker handle, avoiding deformation and unstable clamping caused by single-point force on the speaker handle.

[0020] The advantages of this invention are: by setting two first contour blocks on a first support base and setting two second support bases, with one second contour block on each second support base, and by mounting the first support bases on a second clamping mechanism, the second clamping mechanism clamps the first support bases. Thus, the second clamping mechanism only needs to clamp one first support base to fix the entire first clamping mechanism. In addition, by mounting the first support bases on the second clamping mechanism so that the second support bases face the processing tool of the equipment, and by setting two second support bases to support two second contour blocks respectively, the shape of the second support bases can be more flexible and compact, which is beneficial for the second support bases to avoid the processing tool of the equipment.

[0021] According to some embodiments of the present invention, the second clamping mechanism includes a first support plate, a plurality of first limiting pins disposed on the first support plate, a first pressure block and a first cylinder. The first support plate is used to support the first clamping mechanism. The plurality of first limiting pins respectively abut against and limit the side wall of the first clamping mechanism. The first cylinder is disposed on the first support plate and is used to drive the first pressure block to press the first clamping mechanism.

[0022] The advantages of this invention are: the second clamping mechanism includes a first support plate, multiple first limiting pins disposed on the first support plate, a first pressure block, and a first cylinder. The first support plate supports the first clamping mechanism, the multiple first limiting pins respectively abut against and limit the side wall of the first clamping mechanism, and the first cylinder is disposed on the first support plate. The first cylinder drives the first pressure block to press the first clamping mechanism. It can be understood that the linkage design of the first pressure block and the first cylinder enables rapid clamping, which helps to reduce the time spent on clamping action. In addition, the coordinated positioning of multiple limiting pins ensures the repeatability of the speaker handle clamping accuracy, meeting the requirements of precision machining.

[0023] A clamping assembly according to a second aspect of the present invention includes a speaker handle CNC machining fixture according to a first aspect of the present invention. When the first clamping mechanism and the second clamping mechanism are separated, the auxiliary tool is used to fix the first clamping mechanism to clamp the speaker handle.

[0024] A clamping assembly according to an embodiment of the present utility model has at least the following beneficial effects:

[0025] This utility model enables simultaneous processing and clamping of speaker handles by setting auxiliary tools. When the equipment is processing, the operator can use the auxiliary tools to pre-clamp the next workpiece, achieving seamless connection of the production process. At the same time, the auxiliary tools can improve the efficiency of the first clamping mechanism in clamping speaker handles.

[0026] According to some embodiments of the present invention, the first clamping mechanism includes a first pressing component, a second pressing component, and a connecting component. The first pressing component and the second pressing component cooperate to clamp the speaker handle. The connecting component includes a connecting post and at least one fixing bolt. One end of the connecting post is detachably connected to the first pressing component through the fixing bolt, and the other end of the connecting post is detachably connected to or fixedly connected to the second pressing component through the fixing bolt. The auxiliary tool includes a second support plate, a second pressing block, a second cylinder, and a positioning component. The second support plate is used to support the second pressing component. The second cylinder is disposed on the second support plate and is used to drive the second pressing block to press the second pressing component. The positioning component is used to position the speaker handle so that the speaker handle is positioned in the clamping position of the second pressing component.

[0027] Advantages: This utility model includes a first clamping mechanism comprising a first clamping component, a second clamping component, and a connecting component. The first and second clamping components cooperate to clamp the speaker handle. The connecting component includes a connecting post and at least one fixing bolt. One end of the connecting post is detachably connected to the first clamping component via the fixing bolt, and the other end of the connecting post is detachably or fixedly connected to the second clamping component via the fixing bolt. The auxiliary tool includes a second support plate, a second pressure block, a second cylinder, and a positioning component. The second support plate supports the second clamping component, and the second cylinder is mounted on the second support plate. The second cylinder is used for... The second clamping block is used to press the second clamping component, and the positioning component is used to position the speaker handle so that the speaker handle is positioned in the clamping position of the second clamping component. It can be understood that the positioning component can automatically position the speaker handle, so that the speaker handle can be quickly positioned in the clamping position of the second clamping component, eliminating the need for manual adjustment of the speaker handle and avoiding positioning difficulties caused by the uneven shape of the speaker handle. The automatic clamping structure combined with the second clamping block and the second cylinder helps to reduce the skill requirements of the operator for clamping the second clamping mechanism and improve the clamping efficiency and clamping accuracy of the second clamping mechanism.

[0028] According to some embodiments of the present invention, the positioning component includes a first limiting block, a second limiting block, a third limiting block, and a fourth limiting block. The first limiting block and the second limiting block limit the width of the arc-shaped rod of the speaker handle on both sides, and the third limiting block and the fourth limiting block limit the boss of the speaker handle on both sides along the length of the arc-shaped rod.

[0029] The advantages of this invention are: by including a first limiting block, a second limiting block, a third limiting block, and a fourth limiting block in the positioning component, the first and second limiting blocks limit the width of the arc-shaped rod of the speaker handle on both sides, and the third and fourth limiting blocks limit the boss of the speaker handle on both sides along the length of the arc-shaped rod. It can be understood that the four-limiting block system, which combines the first, second, third, and fourth limiting blocks, can achieve full constraint of the speaker handle in both the width and length directions by the positioning component, completely eliminating the possibility of workpiece displacement. In addition, the limiting is specifically designed for the geometric features of the arc-shaped rod and the boss, ensuring the precise positioning of the complex curved surface of the speaker handle.

[0044] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7This invention describes a CNC machining fixture and clamping assembly for a speaker handle according to an embodiment of the present invention.

[0045] This utility model aims to provide an embodiment of a CNC machining fixture and clamping assembly for a speaker handle.

[0046] Reference Figure 1 For the speaker handle 100, the speaker handle 100 includes an arc-shaped rod 101 and two protrusions 102. The two protrusions 102 are respectively provided at both ends of the arc-shaped rod 101. The protrusions 102 protrude in the bending direction of the arc-shaped rod 101. Two protruding posts 103 are also provided on the protrusions 102.

[0047] Reference Figure 2 In one aspect, this utility model provides a CNC machining fixture for a speaker handle, including a first clamping mechanism and a second clamping mechanism.

[0048] The first clamping mechanism is used to clamp the speaker handle 100.

[0049] The second clamping mechanism is installed on the processing equipment and is used to clamp the first clamping mechanism. The first clamping mechanism and the second clamping mechanism are detachably connected.

[0050] This embodiment features a first clamping mechanism and a second clamping mechanism. The first clamping mechanism clamps the speaker handle 100, while the second clamping mechanism, mounted on the processing equipment, clamps the first clamping mechanism. The first and second clamping mechanisms are detachably connected. This allows the operator to pre-position and clamp the speaker handle 100 onto the first clamping mechanism outside the equipment. When the equipment stops, the entire first clamping mechanism can be quickly mounted onto the second clamping mechanism. This enables the operator to simultaneously position the speaker handle 100 to be processed onto the first clamping mechanism outside the equipment while processing a set of speaker handles 100, avoiding the need to position and clamp uneven speaker handles 100 when the equipment stops. This improves the clamping efficiency of the speaker handle 100 on the equipment, significantly reduces equipment downtime for clamping, and enhances processing efficiency.

[0051] Reference Figure 3 In some specific embodiments, the first clamping mechanism includes a first clamping component 110, a second clamping component 120 and a connecting component 130. The first clamping component 110 and the second clamping component 120 cooperate to clamp the speaker handle 100, and the connecting component 130 is used to detachably connect the first clamping component 110 and the second clamping component 120.

[0052] Understandably, the separate clamping structure of the first clamping component 110 and the second clamping component 120 can adapt to the complex curved shape of the speaker handle 100. In addition, the detachable design of the connecting component 130 makes the clamp more flexible to install and remove, and facilitates the first clamping component 110 and the second clamping component 120 to fix and release the speaker handle 100.

[0053] Specifically, the first pressing component 110 includes a first contour block 140, and the second pressing component 120 includes a second contour block 150. The first contour block 140 and the second contour block 150 abut against and clamp the speaker handle 100.

[0054] Understandably, the first contour block 140 and the second contour block 150 are closely fitted to the surface of the speaker handle 100, which can improve clamping stability, reduce processing vibration caused by loose clamping, and improve processing accuracy and surface quality.

[0055] Further, the first clamping assembly 110 includes a first support base 160, and a first contour block 140 is disposed on the first support base 160; the second clamping assembly 120 includes a second support base 170, and a second contour block 150 is disposed on the second support base 170; the connecting assembly 130 includes a connecting post 180 and at least one fixing bolt 190; one end of the connecting post 180 is fixedly connected to one of the first support base 160 and the second support base 170, and the other end of the connecting post 180 is detachably connected to the other of the first support base 160 and the second support base 170 by fixing bolt 190, or, both ends of the connecting post 180 are detachably connected to the first support base 160 and the second support base 170 by fixing bolt 190 respectively.

[0056] Understandably, on the one hand, the rigid connection structure design between the connecting column 180 and the first support 160 and the second support 170 ensures the uniform distribution of clamping force; on the other hand, the connection method of the fixing bolt 190 not only ensures the connection strength, but also facilitates quick disassembly and assembly, reducing the complexity of operation.

[0057] In some specific embodiments, the fixing bolt 190 can be threaded through the first support 160 and connected to one end of the connecting column 180. The first support 160 is provided with a first countersunk hole for accommodating the nut of the fixing bolt 190, thereby preventing the nut of the fixing bolt 190 from protruding out of the first support 160 and hindering the installation of the first support 160.

[0058] In some specific embodiments, the fixing bolt 190 can be threaded through the second support 170 and connected to one end of the connecting column 180. The second support 170 is provided with a second countersunk hole for accommodating the nut of the fixing bolt 190, thereby preventing the nut of the fixing bolt 190 from protruding out of the second support 170 and hindering the installation of the second support 170.

[0059] In some specific embodiments, two first contour blocks 140 are provided, and two corresponding second contour blocks 150 are provided. The two first contour blocks 140 cooperate with the two second contour blocks 150 to clamp the two positions of the speaker handle 100.

[0060] Understandably, the dual clamping design of the two sets of first contour blocks 140 and second contour blocks 150 enables simultaneous clamping and positioning of the speaker handle 100 at two positions, avoiding deformation and unstable clamping caused by single-point force on the speaker handle 100.

[0061] In some specific embodiments, two first contour blocks 140 are provided on a first support base 160, and two second support bases 170 are provided, one second contour block 150 is provided on each second support base 170. The first support base 160 is mounted on a second clamping mechanism, and the second clamping mechanism clamps the first support base 160. Thus, the second clamping mechanism only needs to clamp one first support base 160 to fix the entire first clamping mechanism. In addition, the first support base 160 is mounted on the second clamping mechanism so that the second support base 170 faces the processing tool of the equipment. By setting two second support bases 170 to support two second contour blocks 150 respectively, the shape of the second support base 170 can be more flexible and compact, which is beneficial for the second support base 170 to avoid the processing tool of the equipment.

[0062] In some specific embodiments, to avoid interference between the first support 160 and the speaker handle 100, the first support 160 may be configured as a square frame.

[0063] In some specific embodiments, the second clamping mechanism includes a first support plate 200, a plurality of first limiting pins 210 disposed on the first support plate 200, a first pressing block 220 and a first cylinder 230. The first support plate 200 is used to support the first clamping mechanism. The plurality of first limiting pins 210 respectively abut against and limit the side wall of the first clamping mechanism. The first cylinder 230 is disposed on the first support plate 200 and is used to drive the first pressing block 220 to press the first clamping mechanism.

[0064] Understandably, the linkage design between the first pressure block 220 and the first cylinder 230 enables rapid clamping, which helps reduce the time spent on clamping actions. In addition, the coordinated positioning of multiple limit pins ensures the repeatability of the speaker handle 100, meeting the requirements of precision machining.

[0065] In some specific embodiments, the first support plate 200 is provided with multiple clamping stations, each clamping station is used to clamp a speaker handle 100, thereby enabling the second clamping mechanism to clamp multiple first clamping mechanisms at the same time, and thus enabling the equipment to process multiple speaker handles 100 at the same time, improving processing efficiency.

[0066] Reference Figure 4 Secondly, this utility model provides a clamping assembly, including a speaker handle CNC machining fixture according to the first aspect embodiment. When the first clamping mechanism and the second clamping mechanism are separated, an auxiliary tool is used to fix the first clamping mechanism to clamp the speaker handle 100.

[0067] In this embodiment, by setting up auxiliary tools, the processing and clamping of the speaker handle 100 can be carried out simultaneously. When the equipment is processing, the operator can use the auxiliary tools to pre-clamp the next workpiece, so as to achieve seamless connection of the production process. At the same time, the auxiliary tools can improve the efficiency of the first clamping mechanism in clamping the speaker handle 100.

[0068] Reference Figure 5 , Figure 6 and Figure 7 In some specific embodiments, the first clamping mechanism includes a first pressing component 110, a second pressing component 120, and a connecting component 130. The first pressing component 110 and the second pressing component 120 cooperate to clamp the speaker handle 100. The connecting component 130 includes a connecting post 180 and at least one fixing bolt 190. One end of the connecting post 180 is detachably connected to the first pressing component 110 via the fixing bolt 190, and the other end of the connecting post 180 is detachably connected to or fixedly connected to the second pressing component 120 via the fixing bolt 190. The auxiliary tool includes a second support plate, a second pressing block 250, a second cylinder 260, and a positioning component 270. The second support plate is used to support the second pressing component 120. The second cylinder 260 is disposed on the second support plate and is used to drive the second pressing block 250 to press the second pressing component 120. The positioning component 270 is used to position the speaker handle 100 so that the speaker handle 100 is positioned in the clamping position of the second pressing component 120.

[0069] Understandably, the positioning component 270 can automatically position the speaker handle 100, enabling the speaker handle 100 to be quickly positioned in the clamping position of the second clamping component 120. This eliminates the need for manual adjustment of the speaker handle 100 and avoids positioning difficulties caused by the uneven shape of the speaker handle 100. Combined with the automatic clamping structure of the second pressure block 250 and the second cylinder 260, this helps to reduce the skill requirements of the operator for clamping the second clamping mechanism and improve the clamping efficiency and accuracy of the second clamping mechanism.

[0070] In some specific embodiments, a first positioning pin is provided on the second support plate, and a first positioning hole is provided on the second clamping assembly. The first positioning pin and the first positioning hole cooperate to position the second clamping assembly, thereby facilitating and quickly positioning the second clamping assembly on the second support plate.

[0071] In some specific embodiments, the positioning component 270 includes a first limiting block 280, a second limiting block 290, a third limiting block 300, and a fourth limiting block 310. The first limiting block 280 and the second limiting block 290 limit the arc rod 101 of the speaker handle 100 on both sides in the width direction, and the third limiting block 300 and the fourth limiting block 310 limit the boss 102 of the speaker handle 100 on both sides in the length direction of the arc rod 101.

[0072] Understandably, the four-limit block system, consisting of the first limit block 280, the second limit block 290, the third limit block 300, and the fourth limit block 310, can achieve full constraint of the speaker handle 100 in both the width and length directions by the positioning component 270, completely eliminating the possibility of workpiece displacement. In addition, the limit is specially designed for the geometric features of the arc rod 101 and the boss 102 to ensure the precise positioning of the complex curved surface workpiece of the speaker handle 100.

[0073] In some specific embodiments, the first limiting block 280 and the second limiting block 290 are connected and fixed to the second support plate by a first bolt. The first limiting block 280 or the second limiting block 290 is provided with a first waist-shaped through hole. The length direction of the first waist-shaped through hole is set along the width direction of the arc rod 101. The first bolt passes through the first waist-shaped through hole and is bolted to the second support plate. Thus, by adjusting the position of the first bolt fixed in the first waist-shaped through hole, the position of the first limiting block 280 or the second limiting block 290 along the width direction of the arc rod 101 can be adjusted. In this way, the first limiting block 280 and the second limiting block 290 can adapt to limiting the arc rod 101 of different widths or can adjust the limiting gap of the first limiting block 280 and the second limiting block 290 on the arc rod 101.

[0074] In some specific embodiments, the third limiting block 300 has a limiting groove on one side. The sidewall of the limiting groove can limit the boss 102 on one side along the length direction of the arc rod 101 and on both sides along the width direction of the arc rod 101. The fourth limiting block 310 limits the boss 102 on the other side along the length direction of the arc rod 101. Thus, the third limiting block 300 and the fourth limiting block 310 can cooperate to limit the boss 102 around its perimeter at the same time, thereby making the limiting of the boss 102 by the third limiting block 300 and the fourth limiting block 310 more precise.

[0075] In some specific embodiments, the fourth limiting block 310 includes a fixed base and a telescopic member. The fixed base is fixedly installed on the second support plate, and the telescopic member is used to abut and limit the boss 102. The telescopic member can slide on the fixed base along the length direction of the arc rod 101 to adjust the limiting position of the boss 102. A second bolt is threadedly connected to the fixed base, and the second bolt abuts against the telescopic member to fix the telescopic member.

[0076] Furthermore, the telescopic component is provided with a first waist-shaped groove extending along the length direction of the arc-shaped rod 101. The second bolt abuts against the bottom wall of the first waist-shaped groove to fix the two ends of the first waist-shaped groove, which are respectively used to abut against the second bolt to limit the maximum telescopic adjustment position of the telescopic component.

[0077] In some specific embodiments, the second support plate is also provided with a second positioning hole, which is used to position the protrusion 103 on the boss 102, thereby making the positioning of the speaker handle 100 by the auxiliary tool more accurate.
