Description

Technical Field

[0001] This utility model relates to the technical field of CNC fixtures, and in particular to a CNC fixture for processing small round cover logos. Background Technology

[0002] Among the components of speaker products, there is a small round cover with the product logo on its surface.

[0003] The logo on the small round cap is usually machined using CNC machining.

[0004] Because the small round cap logo requires a high processing depth, the reference surface of the product (the surface where the logo is located) usually needs to be supported when clamping the product in the fixture. To simplify the clamping method, the product is currently clamped by lifting it from the top. That is, the reference surface of the product is placed on the lifting seat with the product facing upward, and then the lifting seat lifts the product up so that the reference surface of the product abuts against the upper support plate of the fixture.

[0005] However, during the lifting process, the product may become loose and shift during the ascent, and the gap between the product and the fixture is difficult to guarantee after the lifting seat lifts the product to contact the upper support plate. Utility Model Content

[0006] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a CNC fixture for processing small round cover logos, which can ensure that the product will not loosen or shift during the lifting process, while ensuring the gap between the product and the fixture after the lifting seat drives the product to rise and contact the upper support plate.

[0007] A CNC fixture for processing small round cap logos according to an embodiment of the present utility model includes:

[0008] The frame includes a base plate and an upper support plate located above the base plate;

[0009] The lifting assembly includes a first cylinder and a lifting seat. The first cylinder is fixed on the base plate. The lifting seat is used to support the product. The lifting seat is provided with a positioning pin. The positioning pin is used to insert into the positioning hole of the product to position the product. The first cylinder is used to drive the lifting seat to rise and fall. The lifting seat rises to lift the product to abut against the upper support plate. The upper support plate has a first clearance groove that runs vertically through the product. The first clearance groove is used to avoid the processing position of the product.

[0010] The upper support plate is provided with a first air detection hole. The air inlet of the first air detection hole is connected to a first air detector. The air outlet of the first air detection hole is located on the support surface of the upper support plate. The first air detector supplies air to the first air detection hole to detect the air tightness between the product and the support surface of the upper support plate.

[0011] A CNC fixture for machining a small round cap logo according to an embodiment of the present utility model has at least the following beneficial effects:

[0012] 1. This utility model achieves precise positioning by setting a positioning pin on the lifting seat and inserting the positioning pin into the product positioning hole, thereby preventing the product from shifting during the lifting process.

[0013] 2. This utility model provides a first air detection hole on the upper support plate and uses the first air detection hole in conjunction with a first air detector to test the airtightness of the product in contact with the support surface of the upper support plate. This ensures that the product and the support surface of the upper support plate are in complete contact and the gap is controllable, thereby helping to ensure the product processing accuracy.

[0014] 3. This utility model provides a first clearance groove on the upper support plate, which can avoid processing interference and ensure the processing depth requirements.

[0015] According to some embodiments of the present invention, the upper support plate is provided with multiple support stations, each of which is used to support a product. The first air detection port includes a main air channel and multiple branch air channels connected to the main air channel. The branch air channels extend to the support surface of the support station. The main air channel is connected to the first air detector.

[0016] The advantages of this invention are: by setting multiple support stations on the upper support plate, each support station is used to support one product, and the first air inspection hole includes a main air channel and multiple branch air channels connected to the main air channel. The branch air channels extend to the support surface of the support station, and the main air channel is connected to the first air detector. It can be understood that, on the one hand, the parallel layout of multiple support stations can significantly improve processing efficiency, and on the other hand, the coordinated design of the main air channel and multiple branch air channels enables simultaneous air inspection of multiple products, ensuring consistent contact between the products at each support station and the support surface of the upper support plate during batch processing, and reducing the cost of testing equipment.

[0017] According to some embodiments of the present invention, a plurality of the support stations are arranged sequentially along a straight line, the main air duct extends along the arrangement direction of the plurality of support stations, and the air inlet end of the main air duct is located on one side of the upper support plate along the arrangement direction of the plurality of support stations.

[0018] The advantages of this invention are: by arranging multiple support stations sequentially along a straight line, and extending the main air duct along the direction of the arrangement of the multiple support stations, with the air inlet of the main air duct located on one side of the upper support plate along the direction of the arrangement of the multiple support stations, it can be understood that, on the one hand, the straight arrangement of the support stations and the extension of the main air duct in the same direction optimizes the air path structure and helps to reduce airflow loss; on the other hand, the side air intake of the main air duct on the upper support plate facilitates equipment layout and maintenance, and avoids interference from top wiring with the processing area.

[0019] According to some embodiments of the present invention, the lifting seat is provided with a second air detection hole, the air inlet end of the second air detection hole is connected to a second air detector, the air outlet end of the second air detection hole is located on the support surface of the lifting seat, and the second air detector supplies air to the second air detection hole to detect the airtightness between the product and the support surface of the lifting seat.

It can be understood that, on the one hand, the second air detection hole and the second air detector work together to detect the fit between the bottom surface of the product and the lifting seat, preventing positioning deviations caused by uneven bottom surfaces; on the other hand, the first air detection hole and the second air detection hole work together to form a dual air detection system to simultaneously monitor the contact status between the lifting seat and the upper support plate, forming a dual quality assurance.

[0021] According to some embodiments of the present invention, the air inlet of the second air detection port is located on the side wall of the lifting seat, and the air supply pipe of the second air detector is located on the side of the lifting seat.

[0022] The advantages are: by setting the air inlet of the second air detection hole on the side wall of the lifting seat, and the air supply pipe of the second air detector is located on the side of the lifting seat, the side air intake design of the second air detector on the lifting seat avoids the air pipe from getting tangled during the lifting movement, and at the same time avoids the second air detector from obstructing the operator from loading and unloading materials in front of the lifting seat.

[0023] According to some embodiments of the present invention, the base plate has a second clearance groove that runs vertically through the base plate. The second clearance groove is used to avoid the second gas detector or the gas supply pipe of the second gas detector.

[0024] The advantages of this invention are: by setting a second clearance groove that runs vertically through the bottom plate, the second clearance groove is used to avoid the second gas detector or the gas supply pipe of the second gas detector. It can be understood that the second clearance groove provides a protective space for the second gas detector to prevent motion interference. In addition, the through design of the second clearance groove facilitates the concealment of the gas pipe wiring and improves the safety of the equipment.

[0025] According to some embodiments of the present invention, the lifting seat is provided with a vertically penetrating mounting hole, which is used to install the positioning pin. The mounting depth of the positioning pin in the mounting hole is adjusted to adjust the height of the positioning pin protruding from the support surface of the lifting seat.

[0026] The advantages of this invention are: by providing a vertically penetrating mounting hole on the lifting seat, the mounting hole is used to install a positioning pin. The mounting depth of the positioning pin in the mounting hole is adjusted to adjust the height of the positioning pin protruding from the support surface of the lifting seat. Thus, the height-adjustable positioning pin can adapt to products of different thicknesses and improve the versatility of the fixture.

[0027] According to some embodiments of the present invention, the top of the upper support plate has a relief groove, which is located above the first relief groove, and the relief groove is used to avoid machining tools.

[0028] The advantages of this invention are: by setting an avoidance groove on the top of the upper support plate, the avoidance groove is located above the first avoidance groove. The avoidance groove is used to avoid the machining tool. Thus, the avoidance groove provides a buffer space for the tool and prevents the tool from colliding with the upper lifting plate. In addition, the double avoidance structure of the avoidance groove and the first avoidance groove together ensures that the tool path is unobstructed when machining the deep groove of the product logo.

[0029] According to some embodiments of this utility model, the lifting seat is provided with a downwardly extending guide rod, and the base plate is provided with a guide hole that runs vertically through the base plate. The guide rod cooperates with the guide hole for guidance.

[0030] The advantages of this invention are: by providing a downwardly extending guide rod on the lifting seat and a through guide hole on the bottom plate, the guide rod and the guide hole cooperate to guide the product, thereby improving the straightness of the lifting movement of the lifting seat and reducing the risk of product tilting. At the same time, the mechanical guidance enhances the rigidity of the system and reduces the wear caused by the lateral force of the first cylinder.

[0031] According to some embodiments of the present invention, the first cylinder is fixed to the bottom of the base plate, and the base plate has a first through hole that extends vertically through the bottom, through which the telescopic rod of the first cylinder passes.

[0032] The advantages of this invention are: by fixing the first cylinder to the bottom of the base plate, the base plate has a through hole that runs vertically through the bottom, through which the telescopic rod of the first cylinder passes. Thus, the inverted cylinder layout can lower the center of gravity of the equipment and improve operational stability. At the same time, it is beneficial to make full use of the idle space at the bottom of the base plate, improve the space utilization of the fixture, and make the fixture structure more compact.

[0051] Furthermore, the frame 100 also includes at least two vertical plates, which are disposed between the base plate 110 and the upper support plate 120, and the vertical plates are used to support and fix the base plate 110 and the upper support plate 120.

[0052] Furthermore, the frame 100 may also include multiple support columns, which are arranged between the base plate 110 and the upper support plate 120. The support columns are used to support and fix the base plate 110 and the upper support plate 120, thereby improving the stability of the upper support plate 120.

[0053] The lifting assembly 130 includes a first cylinder 140 and a lifting seat 150. The first cylinder 140 is fixed on the base plate 110. The lifting seat 150 is used to support the product 160. The lifting seat 150 is provided with a positioning pin 170, which is used to insert into the positioning hole of the product 160 to position the product 160. The first cylinder 140 is used to drive the lifting seat 150 to rise and fall. The lifting seat 150 rises to lift the product 160 to abut against the upper support plate 120. The upper support plate 120 has a first clearance groove 180 that runs vertically through the product. The first clearance groove 180 is used to avoid the processing position of the product 160.

[0054] In this embodiment, a positioning pin 170 is set on the lifting seat 150. The positioning pin 170 is inserted into the positioning hole of the product 160 to achieve precise positioning and prevent the product 160 from shifting during the lifting process.

[0055] In addition, in this embodiment, a first clearance groove 180 is provided on the upper support plate 120. The first clearance groove 180 can avoid machining interference and ensure the machining depth requirements.

[0056] Reference Figure 3 and Figure 4 Furthermore, the upper support plate 120 is provided with a first air detection hole 190. The air inlet end of the first air detection hole 190 is connected to a first air detector 200, and the air outlet end of the first air detection hole 190 is located on the support surface of the upper support plate 120. The first air detector 200 circulates air into the first air detection hole 190 to detect the air tightness between the product 160 and the support surface of the upper support plate 120.

[0057] In this embodiment, a first air inspection hole 190 is provided on the upper support plate 120. The first air inspection hole 190 is used in conjunction with the first air detector 200 to detect the airtightness of the contact between the product 160 and the support surface of the upper support plate 120. This ensures that the product 160 and the support surface of the upper support plate 120 are fully in contact and the gap is controllable, thereby helping to ensure the processing accuracy of the product 160.

[0058] In some specific embodiments, the upper support plate 120 is provided with multiple support stations, each support station is used to support a product 160, the first air detection port 190 includes a main air channel 210 and multiple branch air channels 220 connected to the main air channel 210, the branch air channels 220 extend to the support surface of the support station, and the main air channel 210 is connected to the first air detector 200.

[0059] Understandably, on the one hand, the parallel layout of multiple support stations can significantly improve processing efficiency. On the other hand, the coordinated design of the main air duct 210 and multiple branch air ducts 220 enables simultaneous air inspection of multiple products 160, ensuring consistent contact between the product 160 at each support station and the support surface of the upper support plate 120 during batch processing, thereby reducing the cost of testing equipment.

[0060] Furthermore, multiple support stations are arranged sequentially along a straight line, and the main air duct 210 extends along the arrangement direction of the multiple support stations. The air inlet end of the main air duct 210 is located on one side of the upper support plate 120 along the arrangement direction of the multiple support stations.

[0061] Understandably, on the one hand, the straight-line arrangement of the support station and the main air duct 210 extending in the same direction optimizes the air path structure and helps reduce airflow loss. On the other hand, the lateral air intake of the main air duct 210 on the upper support plate 120 facilitates equipment layout and maintenance, and avoids interference from top wiring with the processing area.

[0062] Furthermore, multiple lifting components 130 are provided, with one lifting component 130 corresponding to one support station.

[0063] Reference Figure 6 and Figure 7 In some specific embodiments, the lifting seat 150 is provided with a second air detection hole 230. The air inlet end of the second air detection hole 230 is connected to a second air detector 240, and the air outlet end of the second air detection hole 230 is located on the support surface of the lifting seat 150. The second air detector 240 vents air into the second air detection hole 230 to detect the air tightness between the product 160 and the support surface of the lifting seat 150.

[0064] Understandably, on the one hand, the second air detection hole 230 and the second air detector 240 work together to detect the fit between the bottom surface of the product 160 and the lifting seat 150, preventing positioning deviations caused by uneven bottom surfaces. On the other hand, the first air detection hole 190 and the second air detection hole 230 work together to form a dual air detection system to simultaneously monitor the contact status between the lifting seat 150 and the upper support plate 120, thus providing dual quality assurance.

[0065] Furthermore, the air inlet of the second air detection port 230 is located on the side wall of the lifting seat 150, and the air supply pipe of the second air detector 240 is located on the side of the lifting seat 150. Thus, the side air intake design of the second air detector 240 on the lifting seat 150 avoids the air pipe from getting tangled during the lifting movement, and also avoids the second air detector 240 from obstructing the operator from loading and unloading materials in front of the lifting seat 150.

[0066] In some specific embodiments, the base plate 110 has a second clearance groove 250 that runs vertically through the base plate, the second clearance groove 250 being used to avoid the second gas detector 240 or the gas supply pipe of the second gas detector 240.

[0067] Understandably, the second clearance groove 250 provides a protective space for the second gas detector 240 to prevent motion interference. In addition, the through design of the second clearance groove 250 facilitates the concealment of gas pipe wiring and improves equipment safety.

[0068] In some specific embodiments, the lifting seat 150 is provided with a vertically penetrating mounting hole 260 for mounting a positioning pin 170. The mounting depth of the positioning pin 170 in the mounting hole 260 is adjusted to adjust the height of the positioning pin 170 protruding from the support surface of the lifting seat 150. Thus, the height-adjustable positioning pin 170 can adapt to products 160 of different thicknesses, improving the versatility of the fixture.

[0069] Specifically, the positioning pin 170 can be threadedly connected to the mounting hole 260. By utilizing the threaded engagement between the positioning pin 170 and the mounting hole 260, the height of the positioning pin 170 protruding from the support surface of the lifting seat 150 can be adjusted by rotating the positioning pin 170.

[0070] In other embodiments, the positioning pin can be slidably connected to the mounting hole 260, and a support member can be fixedly installed at the bottom of the mounting hole 260. The support member is used to support the positioning pin 170. By replacing the support member with one of different heights or changing the fixed position of the support member at the bottom of the mounting hole 260, the height of the positioning pin 170 protruding from the support surface of the lifting seat 150 can be adjusted.

[0071] In some specific embodiments, the top of the upper support plate 120 has a relief groove 270, which is located above the first relief groove 180. The relief groove 270 is used to avoid the machining tool, thereby providing a buffer space for the tool and preventing the tool from colliding with the upper lifting plate. In addition, the double relief structure of the relief groove 270 and the first relief groove 180 ensures that the tool path is unobstructed when machining the deep groove of the product 160 LOGO.

[0072] In some specific embodiments, the lifting seat 150 is provided with a downwardly extending guide rod 280, and the base plate 110 is provided with a guide hole that runs vertically through the bottom. The guide rod 280 cooperates with the guide hole for guidance. Thus, the cooperation between the guide rod 280 and the guide hole improves the straightness of the lifting movement of the lifting seat 150 and reduces the risk of product 160 tilting. At the same time, the mechanical guidance enhances the rigidity of the system and reduces the wear caused by the lateral force of the first cylinder 140.

[0073] Furthermore, the lifting seat 150 is provided with at least two guide rods 280, and the base plate 110 is provided with at least two guide holes. One guide rod 280 cooperates with one guide hole for guidance, thereby further improving the lifting stability of the lifting seat 150.

The first through hole accommodates the telescopic rod of the first cylinder 140. Thus, the inverted cylinder layout can lower the center of gravity of the equipment and improve operational stability. At the same time, it is beneficial to make full use of the idle space at the bottom of the base plate 110, improve the space utilization of the fixture, and make the fixture structure more compact.
