Description

Technical Field

[0001] The invention relates to the technical field of numerically controlled machine tools, and in particular to a synchronous regulating mechanism for switching workstations of a saw-drill combination machine tool. Background Art

[0002] The sawing and drilling combination machine tool that realizes the function by moving the slider is a machine tool that integrates sawing and drilling functions. It usually has multiple workstations, and different processing operations can be performed at different workstations. The workstation switching synchronization adjustment mechanism is an important component of the sawing and drilling combination machine tool. Its main function is to ensure the synchronization of movement between each workstation when switching between workstations, thereby improving processing accuracy and production efficiency.

[0003] Existing synchronous adjustment mechanisms have difficulties in cleaning and maintenance. Since adjustment needs to be made on the adjustment slides and slide rods, which are inside the machine tool and difficult to directly contact and clean, chips, oil stains, coolants, etc. are easily accumulated in these parts during the processing. Frequent use of the adjustment mechanism will accelerate wear and accumulation of contaminants. These contaminants may enter the gaps between the adjustment slides, causing wear and performance degradation of the moving parts. The drill bit and the adjustment slides are fixed with multiple sets of bolts, which increases the complexity of maintenance. When cleaning or replacing parts, these bolts must be removed first. The presence of multiple sets of bolts means that more time is required to loosen and tighten them one by one during the maintenance process, which prolongs the maintenance cycle and reduces the availability of the machine tool. Therefore, improvements are needed. Summary of the invention

[0004] The purpose of the present invention is to solve the problem in the prior art that the conveyor belt will inevitably come into contact with various pollutants, such as cutting fluid, oil, dust, metal chips, etc., during the process of transporting raw materials or finished products. These pollutants are easily attached to the surface and gaps of the conveyor belt. As the dirt accumulates, the friction coefficient of the conveyor belt surface may change. A synchronous adjustment mechanism for switching workstations of a sawing and drilling combination machine tool is proposed.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a synchronous adjustment mechanism for switching workstations of a saw-drill combination machine tool, comprising a CNC machine bed body, a working platform is arranged on the CNC machine bed body, an adjustment guide rail and a slide rod are also arranged on the CNC machine bed body, a drill bit is connected to the adjustment guide rail and the slide rod, a cleaning mechanism is connected to the adjustment guide rail and the slide rod, a reinforcement mechanism is arranged on the outer wall of the CNC machine bed body between the adjustment guide rail and the slide rod, and a synchronous adjustment mechanism for automatically replacing the tool required for processing is arranged on the CNC machine bed body;

[0006] The CNC machine body is provided with a corresponding slide groove which is plugged and slidably connected with the cleaning mechanism. The cleaning mechanism slides to perform all-round cleaning on the adjustment guide rail and the slide rod. A clamping piece is provided in the reinforcement mechanism. The drill bit is clamped and reinforced by moving the clamping piece downward, and the fixation is quickly released by moving the clamping piece upward.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are:

[0017] 1. In the present invention, by arranging a slide groove and a cleaning mechanism on the main body of the CNC machine tool, all-round cleaning of the guide rails and the slide rods is achieved, and pollutants such as chips, oil stains and coolant are effectively removed.

[0020] 4. In the present invention, the design of automatic cleaning and replacement of parts reduces direct contact and manual intervention by staff, reduces operational risks, provides a more stable working environment by keeping the inside of the machine tool clean, and helps to improve operational safety.

[0028] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0030] Embodiment 1

[0031] like Figure 1-4 As shown, the present invention provides a technical solution: a synchronous adjustment mechanism for switching workstations of a saw-drill combination machine tool, comprising a CNC machine body body 1, a working platform 2 is arranged on the CNC machine body body 1, an adjustment guide rail 3 and a slide bar 4 are also arranged on the CNC machine body body 1, a drill bit 6 is connected to the adjustment guide rail 3 and the slide bar 4, a cleaning mechanism 7 is connected to the adjustment guide rail 3 and the slide bar 4, a reinforcement mechanism 8 is arranged on the outer wall of the CNC machine body body 1 between the adjustment guide rail 3 and the slide bar 4, and a synchronous adjustment mechanism 5 for automatically replacing the tool required for processing is arranged on the CNC machine body body 1;

[0032] A slide groove that is plugged and slidably connected with the cleaning mechanism 7 is correspondingly provided on the main body 1 of the CNC machine tool. The cleaning mechanism 7 slides to perform all-round cleaning of the adjustment guide rail 3 and the slide rod 4. A clamping piece is provided in the reinforcement mechanism 8. The drill bit 6 is clamped and reinforced by moving the clamping piece downward, and the fixation is quickly released by moving the clamping piece upward.

[0033] The cleaning mechanism 7 includes a slider 71 slidably connected in the slide groove, a support frame 72 connected to the slider 71, a first guide rail cleaning brush 73 connected to the support frame 72, a slide rod cleaning brush 74 connected to the support frame 72, and a second guide rail cleaning brush 75 and a third guide rail cleaning brush 76 connected to the support frame 72. The first guide rail cleaning brush 73 is arranged at the rear end of the support frame 72, and the second guide rail cleaning brush 75 and the third guide rail cleaning brush 76 are arranged at the front end of the support frame 72. The brush 76 is arranged in a rectangular shape. The rectangular cleaning brush can better fit the surface of the guide rail, ensuring that the entire width of the guide rail can be covered during the cleaning process, thereby improving the cleaning effect. The sliding rod cleaning brush 74 is arranged to match the arc shape of the sliding rod 4. The arc-shaped cleaning brush matches the shape of the sliding rod, which can more effectively clean the surface of the sliding rod and reduce the accumulation of pollutants and chips. The sliding rod cleaning brush 74 is arranged in the middle position of the support frame 72. Placing the sliding rod cleaning brush in the middle position can clean the guide rail and the sliding rod at the same time when the support frame moves, thereby improving the cleaning efficiency.

[0034] Working principle: When the staff needs to clean the adjusting guide rail 3 and the sliding rod 4, they only need to plug the sliding block 71 into the corresponding sliding groove on the CNC machine body 1, and then move the supporting frame 72 so that the supporting frame 72 slides in the sliding groove through the sliding block 71. During the sliding process, the first guide rail cleaning brush 73 is driven to clean the adjusting guide rail 3, and the second guide rail cleaning brush 75 and the third guide rail cleaning brush 76 simultaneously clean the corresponding adjusting guide rail 3. The middle sliding rod cleaning brush 74 contacts the outer surface of the sliding rod 4 and cleans it synchronously. In order to ensure the cleaning efficiency, the staff can clean back and forth, saving time and effort.

[0035] Embodiment 2

[0036] See also Figure 5-6 The reinforcement mechanism 8 includes a base 81 arranged on the CNC machine body 1, a rotating shaft 82 rotatably connected to the base 81, a connecting rod 83 connected to the rotating shaft 82, and a clamping member connected to the connecting rod 83. The reinforcement mechanism 8 is symmetrically provided with two groups, and the clamping member includes an external thread 84 opened on the outer wall of the connecting rod 83, a threaded sleeve 85 connected to the outer wall of the external thread 84, a reinforcement plate 86 sleeved on the outer wall of the connecting rod 83, and a reinforcement groove 87 opened on the drill bit 6;

[0037] Two symmetrically arranged baffles are arranged on the base 81. The symmetrically arranged baffles help to maintain the stability of the rotating shaft 82 and ensure that the rotating shaft will not deviate during rotation. The rotating shaft 82 is rotatably connected to the two sets of baffles. This design makes the rotating shaft more stable during rotation and reduces the vibration caused by unbalanced rotation. The outer wall of the threaded sleeve 85 is provided with anti-slip textures, and the bottom end of the threaded sleeve 85 is provided with a soft pad. The anti-slip texture increases the convenience of operation, and the soft pad can protect the drill bit and the threaded sleeve from damage during tightening and loosening. The reinforcement plate 86 is set to a rectangular shape. The reinforcement plate 86 is fitted with the threaded sleeve 85. The rectangular reinforcement plate matches the shape of the reinforcement groove 87 on the drill bit, which can ensure that the drill bit can be firmly fixed during clamping to prevent the movement of the drill bit during processing. The bottom end surface of the reinforcement plate 86 is provided with a soft pad, and the shape of the reinforcement groove 87 is set to a rectangular shape. Two groups of reinforcement grooves 87 are symmetrically opened on the drill bit 6. These designs are also for improving the stability of clamping and protecting the drill bit surface from damage.

[0038] Working principle: Before cleaning the adjusting guide rail 3 and the sliding rod 4, the drill bit 6 needs to be disassembled. The staff only needs to disassemble it from the connection between the adjusting guide rail 3 and the sliding rod 4, and then screw the threaded sleeve 85 upwards so that the threaded sleeve 85 slides upwards through the external thread 84 until the threaded sleeve 85 is completely screwed out and removed from the external thread 84. At this time, the threaded sleeve 85 is also removed from the connecting rod 83 to release the limit on the reinforcement groove 87. When cleaning the adjusting guide rail 3 and the sliding rod 4, it is only necessary to rotate the connecting rod 83 so that the connecting rod 83 drives the rotating shaft 82 to rotate on the base 81 and rotate it until it lies flat on the main body 1 of the CNC machine tool. It will not affect the cleaning work of the cleaning mechanism 7. When it is necessary to engage the reinforcement plate 86 in the reinforcement groove 87, it is only necessary to put the reinforcement plate 86 on in advance, and then rotate the connecting rod 83 so that the connecting rod 83 drives the reinforcement plate 86 to be inserted into the reinforcement groove 87.

[0039] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
