The operation is simple and the protective mechanism can be quickly fixed and released.

[0009] Furthermore, the inner side of the limiting piece is provided with a rod, and the two sides of the mounting ring are provided with rod slots, which are inserted into the rod.

[0010] By adopting the above technical solution, a rod is provided on the inner side of the limiting plate, and rod slots are opened on both sides of the mounting ring. The rod is inserted into the rod slot, which further enhances the fixing effect of the protective mechanism and prevents it from shaking or falling off during processing.

[0011] Furthermore, a first linear motor is provided at the top center of the machine, and a movable seat is provided at the moving end of the first linear motor, with a cabinet door placed on top of the movable seat.

[0012] By adopting the above technical solution, a first linear motor is installed in the middle of the top of the machine tool. Its moving end has a movable seat to place the cabinet door, which can accurately control the position of the cabinet door in the horizontal direction, making it convenient for the deep hole drilling machine to operate on the processing position on the cabinet door.

[0013] Furthermore, mounting frames are provided on both sides of the machine base, and a second linear motor is provided between the two mounting frames.

[0014] By adopting the above technical solution, mounting frames are set on both sides of the machine base, and a second linear motor is set between the two mounting frames, which can realize the movement of the deep hole drilling machine in another dimension in the horizontal direction, meet the deep hole processing needs in different positions, and improve the flexibility of the device.

[0015] Furthermore, a third linear motor is installed at the moving end of the second linear motor, and a deep hole drill is provided at the moving end of the third linear motor, with a deep hole drill bit provided at the output end of the deep hole drill.

[0016] By adopting the above technical solution, a third linear motor is installed on the moving end of the second linear motor.

[0017] Furthermore, the spring sleeves are arranged in a circumferential array along the fixed ring, the lever passes through the side wall of the spring sleeve and extends to the outside, the insert is fixedly connected to the limiting piece, and the end of the insert has a tapered structure.

[0018] By adopting the above technical solution, the spring sleeves are distributed in an array along the circumference of the fixed ring, the lever penetrates through the side wall, and the insertion rod is fixed to the limiting plate with a tapered end, making the limiting operation more convenient and labor-saving, the fixing more stable, and improving the reliability and convenience of the installation of the protective mechanism.

[0019] Furthermore, the folding cover has a bellows structure, with its top sealed and fixed to the mounting ring and its bottom sealed and fixed to the counterweight ring. The spherical sliders are arranged equidistantly along the bottom surface of the counterweight ring, and the bottom of each spherical slider protrudes from the bottom surface of the counterweight ring.

[0020] By adopting the above technical solution, the folding cover has a corrugated pipe structure, with the top sealed and fixed to the mounting ring, and the bottom sealed and fixed to the counterweight ring. The spherical sliders are arranged at equal intervals along the circumference of the bottom surface and protrude from the bottom, which can effectively block debris and can adapt to different processing angles, providing good protection.

[0021] In summary, the present invention has the following main advantages: This utility model features a convenient installation and stable limiting structure for the protective mechanism. The mounting ring and the fixed ring's bottom annular slot provide initial positioning and installation foundation for the protective mechanism, allowing it to be quickly and accurately placed in a suitable position below the outside of the deep hole drilling rig. Based on this, the fixed ring and the counterweight ring have a first and second mounting ear at their front ends, a screw that passes through and slides through the first mounting ear, and a nut screwed to the top of the screw for limiting. During installation, after the mounting ring is inserted into the annular slot, the screw on the second mounting ear passes through the first mounting ear, and then the nut is tightened, achieving a stable connection between the protective mechanism and the fixed ring. Disassembly is simple: just loosen the nut and remove the protective mechanism. This design solves the problem of the protective mechanism easily shaking or shifting during use, leading to poor protective effect. It also avoids the problem of shaking or shifting due to vibrations or other factors during processing, which could create gaps in the protective area and prevent effective blocking of debris and cutting fluid. This utility model incorporates a protective mechanism in which the folding cover employs a corrugated pipe structure, with the top sealed and fixed to the mounting ring and the bottom to the counterweight ring. The corrugated pipe structure possesses excellent extensibility and flexibility, allowing it to automatically expand and contract with the movement of the deep hole drilling rig as it processes at different depths and positions, maintaining comprehensive protection of the processing area. Simultaneously, the counterweight ring features a circular array of equidistantly spaced, protruding spherical sliders at the bottom, solving the problem of the protective structure's inflexibility in adapting to different processing surfaces and its potential to interfere with cabinet door processing. During deep hole processing, the cabinet door surface may have different shapes and inclinations. If the traditional protective structure is in too close contact with the cabinet door surface, it may interfere with the processing, hindering its smooth progress. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] A deep hole machining device for cabinet locks, such as Figure 1-4 As shown, the processing device 1 includes a machine base 101 and a deep hole drilling machine 107. A fixing ring 109 is provided on the lower outer side of the deep hole drilling machine 107. An annular slot 110 is provided at the bottom of the fixing ring 109. A protective mechanism 2 is inserted into the annular slot 110. The protective mechanism 2 includes a mounting ring 201, which is inserted into an annular slot 110. A folding cover 203 is provided at the bottom of the annular slot 110, and a counterweight ring 204 is provided at the bottom of the counterweight ring 204. Spherical sliders 205 arranged in an annular array are provided at the bottom of the counterweight ring 204. The front ends of the fixing ring 109 and the counterweight ring 204 are respectively provided with a first mounting ear 206 and a second mounting ear 207. A screw 208 is provided at the top of the second mounting ear 207. The screw 208 passes through the first mounting ear 206 and is slidably connected to the first mounting ear. A nut is screwed to the top of the screw 208, and the nut is used for limiting the position. In this cabinet-locking deep hole machining device, the fixing ring 109 is located on the lower outer side of the deep hole drill 107, and an annular slot 110 is opened at its bottom. The mounting ring 201 of the protective mechanism 2 can be inserted into the slot. The folding cover 203 of the protective mechanism 2, together with the counterweight ring 204 and the spherical slider 205, can form an effective protective barrier during deep hole machining, preventing debris from flying in all directions and avoiding injury to the operator. Moreover, this plug-in installation method makes the installation and disassembly of the protective mechanism 2 very convenient and quick, reducing equipment preparation time and thus improving overall processing efficiency.

[0026] See Figure 1 , Figure 4 A spring sleeve 111 is provided on both sides of the fixing ring 109. A spring groove 112 is provided inside the spring sleeve 111, and a limiting piece 113 engages and slides within the spring groove 112. One side of the limiting piece 113 abuts against a spring 114, and a lever 115 is located at the axis of the spring 114. This structure utilizes the elasticity of the spring 114. When the protective mechanism 2 needs to be fixed, the lever 115 moves the limiting piece 113 into position to lock the protective mechanism 2; when releasing, the lever 115 is operated to retract the limiting piece 113. The operation is simple, allowing for quick fixing and releasing of the protective mechanism 2, meeting different needs during processing.

[0027] See Figure 3 , Figure 4 The inner side of the limiting plate 113 is provided with an insertion rod 116, and the two sides of the mounting ring 201 are provided with insertion rod slots 202. The insertion rod slots 202 are inserted into the insertion rod 116. When the limiting plate 113 moves to the appropriate position, the insertion rod 116 will be inserted into the insertion rod slot 202. This structure further enhances the stability of the fixing based on the initial limiting of the protective mechanism 2 by the spring sleeve 111 and the limiting plate 113. During deep hole machining, the equipment will vibrate. With the insertion of the insertion rod 116 into the insertion rod slot 202, the protective mechanism 2 can be effectively prevented from shaking or falling off, ensuring the continuous and stable operation of the protective function and guaranteeing machining safety.

[0028] See Figure 1 , Figure 2A first linear motor 102 is installed at the top center of the machine base 101. A movable seat 103 is installed at the moving end of the first linear motor 102, and a cabinet door is placed on top of the movable seat 103. The first linear motor 102 can precisely control the horizontal movement distance and position of the movable seat 103. During the deep hole machining of the cabinet door, the machining position varies depending on the size of the cabinet door. By moving the movable seat 103 with the first linear motor 102, the cabinet door can be quickly and accurately adjusted to the appropriate position, allowing the deep hole drilling machine 107 to accurately align with the machining position on the cabinet door, improving machining accuracy and efficiency.

[0029] See Figure 3 , Figure 4 The machine tool 101 has mounting brackets 104 on both sides, and a second linear motor 105 is installed between the two mounting brackets 104. In deep hole machining of cabinet doors, the positions of the deep holes on the cabinet door may be distributed in different horizontal areas. The second linear motor 105 allows the deep hole drill 107 to move in another horizontal dimension. After the first linear motor 102 adjusts the position of the cabinet door in one direction, the second linear motor 105 can further adjust the position of the deep hole drill 107, thereby satisfying the machining of deep holes in different positions on the cabinet door. This enhances the flexibility and applicability of the entire machining device, enabling it to adapt to more diverse machining tasks.

[0030] See Figure 4 A third linear motor 106 is mounted on the moving end of the second linear motor 105. A deep hole drill 107 is mounted on the moving end of the third linear motor 106, and a deep hole drill bit 108 is mounted on the output end of the deep hole drill 107. During deep hole machining of cabinet locks, different specifications of cabinet locks have different requirements for the depth of the deep hole. The third linear motor 106 can drive the deep hole drill 107 to move vertically. By precisely controlling the moving distance of the third linear motor 106, the feed depth of the deep hole drill bit 108 can be precisely controlled, thereby ensuring that the machining depth of each deep hole meets the design requirements and effectively improving the quality and consistency of deep hole machining.

[0031] See Figure 1 , Figure 4The spring sleeves 111 are arranged in a circumferential array along the fixing ring 109. The lever 115 passes through the side wall of the spring sleeve 111 and extends to the outside. The insert rod 116 is fixedly connected to the limiting piece 113, and the end of the insert rod 116 has a tapered structure. The spring sleeves 111 are arranged in a circumferential array along the fixing ring 109. The lever 115 passes through the side wall of the spring sleeve 111 and extends to the outside, allowing the operator to easily operate the lever 115 from the outside. The insert rod 116 is fixedly connected to the limiting piece 113, and the end of the insert rod 116 is designed with a tapered structure. When installing the protective mechanism 2, the tapered insert rod 116 is easier to insert into the insert groove 202 of the mounting ring 201, making the operation more convenient and effortless. At the same time, the circumferentially arrayed spring sleeves 111 can limit the protective mechanism 2 from multiple directions, making the fixation more stable and greatly improving the reliability and convenience of installing the protective mechanism 2.

[0032] See Figure 1 The folding cover 203 has a corrugated tube structure. Its top is sealed and fixed to the mounting ring 201, and its bottom is sealed and fixed to the counterweight ring 204. Spherical sliders 205 are evenly spaced along the bottom surface of the counterweight ring 204, with the bottom of each slider protruding from the bottom surface of the counterweight ring 204. This corrugated tube structure allows the folding cover 203 to extend and retract flexibly, adapting to different height protection requirements. The spherical sliders 205 are evenly spaced along the bottom surface of the counterweight ring 204, ensuring stable placement of the protective mechanism 2 regardless of the cabinet door's angle during processing. Simultaneously, the folding cover 203 effectively blocks flying debris generated during processing, providing comprehensive protection for operators and significantly improving the safety of the processing.

[0033] The implementation principle of this embodiment is as follows: First, before performing deep hole machining of the cabinet lock, the protective mechanism 2 is installed on the fixing ring 109 on the lower outer side of the deep hole drilling machine 107. The specific installation process is as follows: the mounting ring 201 of the protective mechanism 2 is inserted into the annular slot 110 at the bottom of the fixing ring 109. At this time, since the spring sleeves 111 are distributed in a circumferential array along the fixing ring 109, and the limiting piece 113 is engaged and slidably moved in the internal spring groove 112, and the limiting piece 113 abuts against the spring 114 on one side, under the elastic force of the spring 114, the insert rod 116 on the inner side of the limiting piece 113 will be inserted into the insert rod grooves 202 on both sides of the mounting ring 201, thus achieving the initial fixation of the protective mechanism 2. At the same time, the first mounting ear 206 and the second mounting ear 207 are respectively provided at the front ends of the fixing ring 109 and the counterweight ring 204. The screw 208 at the top of the second mounting ear 207 passes through the first mounting ear 206 and slides with it. Tightening the nut at the top of the screw 208 can further limit the protective mechanism 2 and ensure its stable installation. When it is necessary to disassemble the protective mechanism 2, simply loosen the nut and push the lever 115 outward. The lever 115 will cause the limiting piece 113 to slide in the spring groove 112, so that the insertion rod 116 can be pulled out from the insertion rod groove 202. The protective mechanism 2 can then be easily pulled out from the annular slot 110, achieving quick disassembly. During the processing, the cabinet door is placed on the movable seat 103 of the moving end of the first linear motor 102 at the top center of the machine base 101. The position of the cabinet door in the horizontal direction can be adjusted by the first linear motor 102. The second linear motor 105 between the mounting brackets 104 on both sides of the machine base 101 can drive the third linear motor 106 installed at its moving end to move in the horizontal direction. The moving end of the third linear motor 106 is equipped with a deep hole drill 107. The position of the deep hole drill 107 in the vertical direction can be adjusted by the third linear motor 106, thereby achieving precise positioning of the deep hole drill 107 in the horizontal and vertical directions, so that the deep hole drill bit 108 at the output end of the deep hole drill 107 can accurately perform deep hole processing on the cabinet door. The folding cover 203 in the protective mechanism 2 has a corrugated pipe structure. Its top is sealed and fixed to the mounting ring 201, and its bottom is sealed and fixed to the counterweight ring 204. When the deep hole drilling machine 107 is processing, the folding cover 203 can extend and retract with the movement of the deep hole drilling machine 107, and always provide circumferential protection for the processing area. It effectively blocks the debris and cutting fluid generated during the processing from splashing everywhere, protecting the processing environment and the safety of the operators. The bottom of the counterweight ring 204 has spherical sliders 205 arranged in a ring array at equal intervals, and the bottom of each spherical slider 205 protrudes from the bottom surface of the counterweight ring 204. During the processing, the spherical sliders 205 can roll on the cabinet door surface, which can make the protective mechanism 2 fit the cabinet door surface better, improve the sealing and comprehensiveness of the protection, and will not interfere with the processing of the cabinet door. At the same time, it can also adapt to the processing surface of cabinet doors of different shapes, enhancing the versatility of the device.
