Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, and more specifically to a protective device for mechanical processing equipment. Background Art

[0002] Mechanical processing refers to the process of changing the shape, size or performance of a workpiece through a mechanical device. With the continuous development of industrial mechanization, there are more and more mechanical processing industries. In the process of mechanical processing, it is often necessary to drill and cut the mechanical workpiece to facilitate subsequent processing and use. In order to prevent materials from splashing and accidentally injuring people during the mechanical processing, protective devices are needed to protect people.

[0003] For example, the authorization announcement number CN220260350U, a protective device for mechanical processing equipment, including a workbench and a protective mechanism, the protective mechanism is arranged above the workbench, the protective mechanism is composed of a first mounting frame, a second mounting frame and a rectangular protective frame, the rectangular protective frame is installed between the first mounting frame and the second mounting frame, a movable plate is installed on the inner wall surface of the first mounting frame, and a threaded hole is opened through the surface of the movable plate. The utility model sets a protective mechanism, and the protective mechanism is composed of a first mounting frame, a rectangular protective frame and a second mounting frame. When the equipment processes mechanical parts, the rectangular protective frame can be used to comprehensively protect the parts in four directions, front, back, left and right. It not only reduces the damage to the staff caused by the generated debris, but also avoids the debris from flying around and affecting the overall cleanliness of the workbench, changing the traditional protection method of relying on a single protective plate in a single direction, and greatly improving its protection range. However, the protective device has the following disadvantages during use:

[0004] During the use of the above-mentioned protective device, when the mechanical processing equipment hits the tool during machining and causes the workpiece to splash, the splashed workpiece will carry a large kinetic energy. When the workpiece carrying a large kinetic energy hits the rectangular protective frame, if the rectangular protective frame intercepts the workpiece, its kinetic energy will be transmitted to the screw rod used for transmission, which can easily cause the screw rod to deform and the maintenance cost is high. Therefore, the utility model provides a protective device for mechanical processing equipment. Utility Model Content

When the workpiece carrying a large kinetic energy hits the rectangular protective frame, if the rectangular protective frame intercepts the workpiece, its kinetic energy will be transmitted to the screw rod used for transmission, which may easily cause the screw rod to deform and result in high maintenance costs.

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] (1) In this scheme, when it is necessary to place a workpiece to be processed, the motor is started, and the motor will drive the threaded screw to rotate. The rotating threaded screw cooperates with the internal thread sleeve, the return connection frame and the buffer mechanism to drive the protective cover to move upward. After the protective cover moves upward and opens, the workpiece to be processed can be placed on the workbench, and then the motor is controlled to rotate in the opposite direction to close the protective cover. The closed protective cover can fully surround the workpiece to be processed, thereby protecting the personal safety of surrounding workers.

[0020] (2) In this scheme, when the workpiece to be processed splashes due to the collision of the drilling equipment, the splashed workpiece will hit the protective cover, and the protective cover will receive the kinetic energy of the impact. Since the protective cover is connected to the threaded screw through a circular connecting frame and a buffer mechanism, the protective cover will pass through the buffer mechanism before transferring the kinetic energy to the threaded screw. The buffer mechanism can buffer the kinetic energy, thereby reducing the kinetic energy impact on the threaded screw, thereby reducing the possibility of deformation and damage to the threaded screw, and can effectively reduce the maintenance cost.

[0021] (3) In this solution, the protective cover and the circular connecting frame are connected by a latch. When the latch is pulled out, the through-connecting block 1 and the through-connecting block 2 can be separated from each other, and then the protective cover and the circular connecting frame can also be separated from each other. Therefore, when the protective cover is damaged, it is convenient for personnel to disassemble and replace it. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0030] Example

[0031] like Figure 1-5 As shown, a protective device for mechanical processing equipment includes a workbench 1, a protective cover 2 is arranged on the upper surface of the workbench 1, a drilling device 11 is fixedly connected to the upper surface of the workbench 1, the protective cover 2 is sleeved on the outer side of the drilling device 11, and a circular connection frame 3 is arranged on the back of the protective cover 2;

[0032] A mounting seat 4 is fixedly connected to one side of the workbench 1, a motor 5 is fixedly connected to the upper end of the mounting seat 4, a threaded screw 6 is fixedly connected to the output shaft of the motor 5, an internal threaded sleeve 7 is threadedly connected to the outer circumference of the threaded screw 6, a return-shaped connection frame 8 is fixedly connected to the outer circumference of the internal threaded sleeve 7, a pair of buffer mechanisms 9 are fixedly connected to the four sides of the return-shaped connection frame 8, and one end of the buffer mechanism 9 is fixed to the inner wall of the return-shaped connection frame 3;

[0033] A limit rod 12 is also fixedly connected to one side of the workbench 1, and the limit rod 12 is attached to the back of the protective cover 2;

[0034] The buffer mechanism 9 includes a connecting column 1 91, a connecting column 2 92 and a spring 2 93. The connecting column 1 91 is fixedly connected to one side of the circular connecting frame 8. The connecting column 2 92 is embedded at one end of the connecting column 1 91. The outer circumferential surfaces of the connecting column 1 91 and the connecting column 2 92 are sleeved with the spring 2 93. The two ends of the spring 2 93 are fixed to the circular connecting frame 8 and the circular connecting frame 3.

[0035] During use, when it is necessary to place a workpiece to be processed, the motor 5 is started, and the motor 5 will drive the threaded screw 6 to rotate. The rotating threaded screw 6 cooperates with the internal thread sleeve 7, the return-type connection frame 8 and the buffer mechanism 9 to drive the protective cover 2 to move upward. After the protective cover 2 moves upward and opens, the workpiece to be processed can be placed on the workbench 1, and then the motor 5 is controlled to rotate in the opposite direction to close the protective cover 2. The closed protective cover 2 can fully surround the workpiece to be processed, thereby protecting the personal safety of surrounding workers;

[0036] Since the limiting rod 12 is pressed against the back of the protective cover 2, the protective cover 2 is limited. Therefore, when the threaded screw 6 rotates, the internal threaded sleeve 7 will not rotate synchronously with the threaded screw 6. Therefore, when the threaded screw 6 rotates, the protective cover 2 can move up and down;

[0037] The motor 5 is specifically a servo motor, which can realize forward and reverse rotation;

[0038] When the workpiece to be processed splashes due to the collision of the drilling equipment 11, the splashed workpiece will hit the protective cover 2, and the protective cover 2 will receive the kinetic energy of the impact. Since the protective cover 2 is connected to the threaded screw 6 through the circular connecting frame 3 and the buffer mechanism 9, the protective cover 2 will pass through the buffer mechanism 9 before transferring the kinetic energy to the threaded screw 6. The buffer mechanism 9 can buffer the kinetic energy, thereby reducing the kinetic energy impact on the threaded screw 6, thereby reducing the possibility of deformation and damage of the threaded screw 6, and effectively reducing the maintenance cost.

[0039] like Figure 1-4 As shown, two pairs of through-connecting blocks 2 31 are fixedly connected on both sides of the circular connecting frame 3, a through-connecting block 13 is fixedly connected on one side of the workbench 1, and the through-connecting block 1 22 corresponds to the through-connecting block 2 31 one to one. A latch 23 passes through and is slidably connected to the through-connecting block 1 22, and a spring 24 is fixedly connected to one side of the latch 23. One end of the spring 24 is fixed to one side of the through-connecting block 1 22, and one end of the latch 23 is engaged with the through-connecting block 2 31.

[0040] When in use, the protective cover 2 and the circular connection frame 3 are connected by the latch 23. When the latch 23 is pulled out, the through-connection block 1 22 and the through-connection block 2 31 can be separated from each other, and then the protective cover 2 and the circular connection frame 3 can also be separated from each other. Therefore, when the protective cover 2 is damaged, it is convenient for personnel to disassemble and replace it.

[0041] The function of the spring 1 24 is to prevent the latch 23 from falling off and to improve the stability of the latch 23 after installation.

[0042] like Figure 3-4As shown, a stopper 221 is embedded in the upper end of the through-connecting block 22 , and the lower end of the stopper 221 contacts the latch 23 .

[0043] During use, when the latch 23 is pulled out, the stopper 221 is pushed downward, and the stopper 221 can block the latch 23 to prevent the latch 23 from automatically resetting under the action of the spring, thereby facilitating disassembly by personnel.

[0044] like Figure 1 As shown, the protective cover 2 is transparent.

[0045] When in use, the transparent protective cover 2 allows personnel to observe the processing status of the workpiece.

[0046] like Figure 2 As shown, an elastic sealing strip 21 is fixedly connected to the lower end of the protective cover 2.

[0047] During use, when the protective cover 2 moves downward and closes, the elastic sealing strip 21 can improve the sealing between the protective cover 2 and the surface of the workbench 1, thereby further preventing the debris generated during processing from splashing to the outside, thereby further improving the protective effect.

[0048] In summary, the specific working process of this scheme is as follows: when it is necessary to place the workpiece to be processed, start the motor 5, the motor 5 will drive the threaded screw 6 to rotate, the rotating threaded screw 6 cooperates with the internal thread sleeve 7, the return-type connection frame 8 and the buffer mechanism 9 to drive the protective cover 2 to move upward, and after the protective cover 2 moves upward and opens, the workpiece to be processed can be placed on the workbench 1, and then the motor 5 is controlled to rotate in the opposite direction to close the protective cover 2. The closed protective cover 2 can fully surround the workpiece to be processed, thereby protecting the personal safety of surrounding workers;

[0049] Among them, when the workpiece to be processed is splashed due to the collision of the drilling equipment 11, the splashed workpiece will hit the protective cover 2, and the protective cover 2 will receive the kinetic energy of the impact. Since the protective cover 2 is connected to the threaded screw 6 through the circular connecting frame 3 and the buffer mechanism 9, the protective cover 2 will pass through the buffer mechanism 9 before transferring the kinetic energy to the threaded screw 6. The buffer mechanism 9 can buffer the kinetic energy, thereby reducing the kinetic energy impact on the threaded screw 6, thereby reducing the possibility of deformation and damage of the threaded screw 6, and can effectively reduce the maintenance cost.

[0050] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
