Description

Technical Field

[0001] This utility model belongs to the field of clamping rotary table technology, specifically relating to a PCB milling cutter clamping rotary table. Background Technology

[0002] PCB milling cutters are key tools used for drilling, contour cutting, grooving, and milling conductive layers. During processing, PCB milling cutters are fixedly mounted on milling machines. When PCB milling cutters are processed on milling machines, they need to be fixedly mounted. Usually, they are clamped and rotated by a clamping rotary table. Existing clamping rotary tables are the mounting and operating equipment used to fix and rotate PCB milling cutters during processing.

[0003] Existing clamping rotary tables directly embed the mounting end of the PCB milling cutter into the clamping seat for clamping and fixing. However, it is not easy to strengthen the fixation after installation, which makes it prone to loosening and instability under long-term operation and stress. This loosening and instability can easily lead to danger. At the same time, a gap appears at the top of the PCB milling cutter after installation, which is not easy to protect and allows dirt to enter. This affects the convenience of strengthening the fixation and protection of the clamping rotary table when installing and processing PCB milling cutters. Therefore, this utility model proposes a clamping rotary table for PCB milling cutter processing. Utility Model Content

[0004] The purpose of this utility model is to provide a PCB milling cutter clamping rotary table to solve the problems mentioned in the background art, such as the PCB milling cutter being easily loosened and unstable after long-term operation and under stress, which can easily lead to danger when loosened and unstable, and the gap at the top of the PCB milling cutter after installation, which makes it difficult to protect and allows dirt to enter.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PCB milling cutter clamping rotary table, comprising a clamping rotary table body, the clamping rotary table body including a rotary table plate, four fixing seats being equidistantly mounted on the upper surface of the rotary table plate by bolts, a rotary motor being fixedly mounted inside the fixing seats, a drive connecting ring being fixed to the end of the rotary motor by bolts, a PCB milling cutter clamping seat being fixed to the top of the drive connecting ring, and the clamping rotary table body further comprising:

[0006] An auxiliary reinforcement mechanism is provided, and the auxiliary reinforcement mechanism includes an auxiliary reinforcement component disposed at the top of the PCB milling cutter clamping seat, wherein a clamping protection component is disposed on the inner surface of the top of the auxiliary reinforcement component;

[0007] A stabilization control mechanism, comprising a first support control component disposed on the outer surface of the drive connecting ring inside the fixed base, a second support control component disposed on the upper surface of the outer surface of the drive connecting ring located on the fixed base, and a rolling component disposed on the lower surface of the second support control component.

[0008] Preferably, the auxiliary reinforcement component includes an internal reverse thread fixing ring welded and fixed to the top of the PCB milling cutter clamping seat, an external reverse thread reinforcement ring being connected to the internal reverse thread of the internal reverse thread fixing ring, and a clamping protrusion ring being welded at equal intervals to the inner surface edge of the external reverse thread reinforcement ring.

[0009] Preferably, the top end of the external reverse thread reinforcing ring is provided with an internal hexagonal groove, and the internal hexagonal groove and the top end of the external reverse thread reinforcing ring are an integral structure.

[0010] Preferably, the compression protection assembly includes a rubber guard plate that is fixedly installed at the top of the inner side of the external reverse thread reinforcing ring by screws, and the inner surface edge of the rubber guard plate is integrally provided with a compression rubber ring.

[0011] Preferably, the support control assembly includes an inner control ring that is fixedly mounted on the outer surface of the drive connecting ring and located inside the fixed seat by fixing bolts, and the inner control ring is rotatably connected to the interior of the fixed seat.

[0012] Preferably, the second support control component includes an outer control ring fitted onto the outer surface of the drive connecting ring located on the upper surface of the fixed seat. The top end of the outer control ring is integrally provided with a mounting ring, and the edge of the mounting ring is threaded with a fixing screw.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By designing an auxiliary reinforcement mechanism, after the PCB milling cutter is clamped and installed by the PCB milling cutter clamping seat, the outer reverse thread reinforcement ring is rotated in the reverse direction inside the inner reverse thread fixing ring, causing the pressure protrusion ring to move down and press tightly against a suitable position on the outer surface of the PCB milling cutter. This facilitates the clamping and installation of the PCB milling cutter and then rotates it in the reverse direction for reinforcement, thus making it easier to reinforce and stabilize the PCB milling cutter for use. At the same time, when debris generated during processing falls, it is protected by the rubber guard plate and the pressure rubber ring, making it difficult for it to enter the interior. This improves the convenience of the clamping rotary table body in strengthening the fixation and protection of the PCB milling cutter during installation and processing. Attached Figure Description

Detailed Implementation

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

[0024] Please see Figures 1 to 6This utility model provides a technical solution: a PCB milling cutter clamping rotary table, including a clamping rotary table body 100, the clamping rotary table body 100 including a rotary table plate 101, four fixing seats 102 are fixedly mounted on the upper surface of the rotary table plate 101 at equal intervals by bolts, a rotary motor 105 is fixedly mounted inside the fixing seat 102, a drive connecting ring 103 is fixed to the end of the rotary motor 105 by bolts, a PCB milling cutter clamping seat 104 is fixed to the top of the drive connecting ring 103, and the clamping rotary table body 100 is also provided with:

[0025] An auxiliary reinforcement mechanism is provided, which includes an auxiliary reinforcement component disposed at the top of the PCB milling cutter clamping seat 104. The inner surface of the top of the auxiliary reinforcement component is provided with a clamping protection component. After the PCB milling cutter is clamped and installed inside the PCB milling cutter clamping seat 104, the auxiliary reinforcement mechanism further reinforces and installs the PCB milling cutter, which facilitates more stable use with double reinforcement.

[0026] To facilitate the clamping and reinforcement of the PCB milling cutter after installation, the auxiliary reinforcement component is preferably provided in this embodiment as follows: The auxiliary reinforcement component includes an internal reverse threaded retaining ring 1041 welded to the top of the PCB milling cutter clamping seat 104. An external reverse threaded reinforcement ring 1042 is connected to the internal reverse thread of the internal reverse threaded retaining ring 1041. A pressing protrusion ring 1046 is welded at equal intervals to the inner surface edge of the external reverse threaded reinforcement ring 1042. The external reverse threaded reinforcement ring 1042, when rotated in the reverse direction within the internal reverse threaded retaining ring 1041, causes the pressing protrusion ring 1046 to press against the outer surface of the PCB milling cutter for reinforcement. An internal hexagonal slot 1043 is provided at the top of the external reverse threaded reinforcement ring 1042, allowing a wrench to be engaged within the internal hexagonal slot 1043 to adjust the external reverse threaded reinforcement ring 1042.

[0027] In order to facilitate the closure and protection of gaps at the fixed installation location by means of a tight-fitting protective component, in this embodiment, preferably, the tight-fitting protective component includes a rubber guard plate 1045 fixed to the top of the inner part of the outer reverse thread reinforcing ring 1042 by screws. The inner surface edge of the rubber guard plate 1045 is integrally provided with a tight-fitting rubber ring 1044. After the outer reverse thread reinforcing ring 1042 is rotated in the opposite direction to assist in the reinforcement installation, the tight-fitting rubber ring 1044 and the rubber guard plate 1045 tightly press and close the gap at the installation location to protect it, making it difficult for dirt to enter the interior.

[0028] The stabilization control mechanism includes a support control component one disposed on the outer surface of the drive connecting ring 103 inside the fixed base 102, a support control component two disposed on the upper surface of the outer surface of the drive connecting ring 103 located on the fixed base 102, and a rolling component disposed on the lower surface of the support control component two. When the drive connecting ring 103 drives the PCB milling cutter clamping base 104 to rotate, the stabilization control mechanism performs a stable rotation machining operation on the drive connecting ring 103.

[0029] In order to facilitate the rotation of the bottom end of the drive connecting ring 103 inside the fixed seat 102 by means of the support control component, in this embodiment, preferably, the support control component includes an inner control ring 1033 which is fixedly installed on the outer surface of the drive connecting ring 103 inside the fixed seat 102 by fixing bolts, and the inner control ring 1033 is rotatably connected to the inside of the fixed seat 102, so that the drive connecting ring 103 can drive the inner control ring 1033 to rotate inside the fixed seat 102 during the rotation operation, thereby achieving stable control.

[0030] To facilitate stable rotation adjustment of the top end of the drive connecting ring 103 on the upper surface of the fixed seat 102 via the second support control component, in this embodiment, preferably, the second support control component includes an outer control ring 1031 fitted onto the outer surface of the drive connecting ring 103 located on the upper surface of the fixed seat 102. An integral mounting ring 1032 is provided at the top end of the outer control ring 1031. A fixing screw 1036 is threaded onto the edge of the mounting ring 1032, and the mounting ring 1032 is fixedly connected to the outer surface of the drive connecting ring 103 via the mounting ring 1032 and the fixing screw 1036. The outer control ring 1031 can be fixedly installed via the mounting ring 1032 and the fixing screw 1036, facilitating stable support and rotation operation of the top end of the drive connecting ring 103 after the outer control ring 1031 is fixedly installed.

[0031] In order to facilitate stable support and control of the outer control ring 1031 through the rolling assembly, in this embodiment, preferably, the rolling assembly includes rolling grooves 1034 equally spaced on the lower surface of the outer control ring 1031. Rolling balls 1035 roll inside the rolling grooves 1034, and the outer surface of the rolling balls 1035 rolls in contact with the surface of the fixed seat 102. When the outer control ring 1031 is rotated, the outer control ring 1031 rotates, causing the rolling balls 1035 to contact the surface of the fixed seat 102 and smoothly support the rotation, resulting in more stable operation.

[0032] The working principle and usage process of this utility model: When using this PCB milling cutter clamping rotary table, the lower surface of the rotary table plate 101 is directly fixedly installed on the top of the main motor of the machine tool, which facilitates the rotation operation of the clamping rotary table body 100 during processing. The mounting end of the PCB milling cutter used for processing is then embedded into the PCB milling cutter clamping seat 104 and clamped and fixed. The rotary motor 105 drives the drive connecting ring 103, the PCB milling cutter clamping seat 104 and the PCB milling cutter to rotate for processing, which facilitates the continuous rotation of the clamping rotary table body 100 for processing.

[0033] Then, when the clamping rotary table body 100 is installed before processing and use, before the PCB milling cutter is embedded in the PCB milling cutter clamping seat 104, the PCB milling cutter mounting end passes through the interior of the outer reverse thread reinforcing ring 1042 and the tight rubber ring 1044 until it is embedded in the interior of the PCB milling cutter clamping seat 104 for clamping and installation. After the PCB milling cutter is clamped and installed by the PCB milling cutter clamping seat 104, the outer reverse thread reinforcing ring 1042 is rotated in the reverse direction inside the inner reverse thread fixing ring 1041 to drive the pressing protrusion ring 1046 to move down and press it tightly at a suitable position on the outer surface of the PCB milling cutter. This makes it easy to clamp and install the PCB milling cutter and then rotate it in the reverse direction for reinforcement and installation. This makes it easier to reinforce and stabilize the PCB milling cutter for use. At the same time, when the debris generated during processing falls, it is protected by the rubber guard plate 1045 and the tight rubber ring 1044, making it difficult for it to enter the interior. This improves the convenience of the clamping rotary table body 100 in strengthening the fixation and protection of the PCB milling cutter during installation and processing.

[0034] Finally, when the clamping rotary table body 100 is processed after fixed installation, the rotary motor 105 drives the drive connecting ring 103, the PCB milling cutter clamping seat 104 and the PCB milling cutter to rotate and process. At this time, the drive connecting ring 103 rotates inside the fixed seat 102 and is supported by the rotation of the inner control ring 1033. The top of the drive connecting ring 103 drives the outer control ring 1031 to rotate and support the top of the drive connecting ring 103 on the surface of the fixed seat 102. When the outer control ring 1031 rotates, it drives the ball bearing 1035 to contact the outer surface of the fixed seat 102 and roll inside the rolling groove 1034. This facilitates the stable rotation support of the outer control ring 1031, so that the drive connecting ring 103 drives the PCB milling cutter clamping seat 104 and the PCB milling cutter to rotate stably and support the rotation. Moreover, when the rotation is subjected to external force during processing, it is not easy to cause instability, thus improving the support stability of the drive connecting ring 103 of the clamping rotary table body 100 during processing after installation.
