Description

Technical Field

[0001] The invention belongs to the technical field of automation equipment, and in particular relates to a servo driver housing structure. Background Art

[0002] A servo drive is a device that controls a servo motor. It is responsible for receiving control signals and adjusting the motor's speed, position, and torque to achieve precise motion control. It converts control signals into drive signals for the motor to ensure that the motor runs according to predetermined instructions. The housing of a servo drive is usually made of metal, such as aluminum or steel. The design of the housing helps protect the internal circuit from external environmental influences such as dust, moisture, or impact, and also helps dissipate heat to prevent the drive from overheating.

[0003] The casing of a servo drive is generally provided with a cover plate, which can be opened or closed to provide protection when the servo drive is in use, or can be opened to maintain the internal components of the starter casing. In some prior arts, the cover plate of the servo drive is generally fixed to the casing by multiple sets of bolts. When it is necessary to open the casing for maintenance of the internal components, the bolts need to be turned multiple times to remove the cover plate before maintenance can be carried out. When the maintenance is completed and the cover plate is installed, the bolts still need to be turned multiple times to install the cover plate, which is relatively cumbersome and reduces the efficiency of maintenance. Therefore, a servo drive casing structure is proposed to address the above problems. Summary of the invention

[0004] In order to solve the problems raised in the above background technology, the present invention provides a servo drive housing structure, which solves the problem of the prior art that the cover plate is troublesome to disassemble and install.

[0006] Preferably, the fixing block A is fixedly connected to the top outer wall of the shell, and the rotating shaft is rotatably connected to the inner wall of the fixing block B.

[0008] Preferably, the protrusion is clamped with the groove, the spiral spring is fixedly connected to the outer wall of the rotating shaft, and the rotating shaft is fixedly connected to the inner wall of the cover plate.

[0009] Preferably, the adjustment mechanism includes a movable plate, the inner wall of the movable plate is elastically connected to a clamping block via a telescopic spring, the inner wall of the movable plate is rotatably connected to a threaded rod, the outer wall of the threaded rod is threadedly connected to a fixed plate, and the outer wall of the base is provided with a clamping groove.

[0010] Preferably, the movable plate is slidably connected to the inner wall of the base, the clamping block is slidably connected to the inner wall of the movable plate, and the fixed plate is slidably connected to the inner wall of the movable plate.

[0011] Preferably, one end of the telescopic spring is fixedly connected to the outer wall of the clamping block, the other end of the telescopic spring is fixedly connected to the inner wall of the movable plate, and the clamping block is clamped with the clamping slot.

[0012] Preferably, the buffer mechanism comprises a round rod, the outer wall of the round rod is fixedly connected with a rubber pad, the outer wall of the bottom end of the moving block is hinged with a damping ring through a connecting rod, and the inner wall of the base is fixedly connected with a buffer spring.

[0013] Preferably, the round rod is fixedly connected to the inner wall of the base, the rubber pad is in contact with the inner wall of the damping ring, and the moving block is slidably connected to the inner wall of the base.

[0014] Preferably, one end of the connecting rod is hinged to the damping ring, the other end of the connecting rod is hinged to the bottom outer wall of the moving block, and the buffer spring is fixedly connected to the bottom outer wall of the moving block.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a rotating shaft and a slider and other structures to cooperate. When the cover plate needs to be opened to maintain the internal components of the shell, the pull rod can be pulled outward to release the limit of the cover plate and flip the cover plate upward to open for maintenance. When the cover plate needs to be closed, the scroll spring can drive the cover plate to close automatically by pulling the pull rod, and the cover plate can be kept in an open or closed state by the engagement of the protrusion and the groove, so that the cover plate can be opened or closed without turning the bolts multiple times, thereby improving the efficiency of maintenance and being relatively simple. The present invention cooperates with structures such as a movable plate and a fixed plate. When the bolts on the equipment are at different positions from the through-slots on the fixed plate and the housing cannot be installed, the clamping block can be pressed to move the movable plate laterally, and the threaded rod can be rotated to drive the fixed plate to move in the inner wall of the movable plate, so as to adjust the position of the through-slots on the fixed plate to correspond to the position of the bolts, so that the bolts can pass through the through-slots to install and fix the base and the housing, so that the device can be installed on equipment of different specifications and different bolt positions, thereby improving the adaptability of the device and making it more flexible. The present invention cooperates with structures such as buffer springs and round rods. When the vibration is transmitted to the base and the shell during operation of the equipment, the buffer spring is continuously forced to shrink and rebound, and the moving block drives the connecting rod to flip, so that the damping ring continuously moves on the surface of the round rod, thereby increasing the friction force, thereby reducing the amplitude of movement of the moving block, reducing the amplitude of vibration received by the shell, and further reducing the influence of the vibration on the shell and its internal components, thereby reducing the problem of internal components being damaged by large vibrations and being unable to be used normally.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figures 1 to 6 As shown, the present invention provides a servo driver housing structure, including a housing 1, a moving block 4 is fixedly connected to the bottom outer wall of the housing 1, a base 5 is provided on the bottom outer wall of the moving block 4 through a buffer mechanism, an adjustment mechanism 6 is provided on the outer wall of the base 5, and a cover plate 2 is provided on the top outer wall of the housing 1 through a flipping mechanism 3; the flipping mechanism 3 includes a fixed block A302, an inner wall of the fixed block A302 is rotatably connected to a rotating shaft 301, a fixed block B303 is fixedly connected to the top outer wall of the housing 1, an inner wall of the fixed block B303 is elastically connected to a slider 306 through a connecting spring 304, a groove 309 is provided on the outer wall of the slider 306, a pull rod 305 is fixedly connected to the outer wall of the slider 306, a volute spring 307 is fixedly connected to the inner wall of the fixed block B303, a protrusion 308 is fixedly connected to the outer wall of the rotating shaft 301, and a filter screen 7 is fixedly connected to the bottom outer wall of the cover plate 2.

[0020] The above scheme is adopted: the shell 1 is the main body of the driver shell. When the shell 1 is used, the cover 2 needs to be closed. The outer wall of the cover 2 is provided with multiple sets of ventilation holes, and a filter 7 is arranged under the cover 2. During use, the ventilation holes can play a heat dissipation effect, and the filter 7 can prevent dust from entering the interior of the shell 1 from the ventilation holes and affecting the internal components; through the setting of the flip mechanism 3, the cover 2 can be opened or closed conveniently and quickly to maintain the internal components of the shell 1; when the servo drive is in use, the shell 1 needs to be fixedly installed on the equipment by bolts for line connection , and through the adjustment mechanism 6, it can be connected to the equipment with bolts, and the adjustment mechanism 6 can be moved to adjust according to the bolts in different positions on different equipment, which has higher adaptability; after installation, when the equipment is running, vibration will be generated. Through the buffer mechanism, the impact of equipment vibration on the electronic components inside the shell 1 can be reduced, and the vibration amplitude of the components inside the shell 1 can be reduced to avoid the problem of excessive vibration amplitude causing damage to the internal components and making them unusable; the fixed block A302 and the fixed block B303 are both fixedly connected to the top outer wall of the shell 1, and when the cover plate 2 is flipped, the shaft 301 rotates synchronously.

[0021] like Figures 2 to 4As shown, the fixed block A302 is fixedly connected to the top outer wall of the shell 1, and the rotating shaft 301 is rotatably connected to the inner wall of the fixed block B303; one end of the connecting spring 304 is fixedly connected to the outer wall of the slider 306, and the other end of the connecting spring 304 is fixedly connected to the inner wall of the fixed block B303, and the outer wall of the slider 306 is slidably connected to the inner wall of the fixed block B303; the protrusion 308 is clamped with the groove 309, the spiral spring 307 is fixedly connected to the outer wall of the rotating shaft 301, and the rotating shaft 301 is fixedly connected to the inner wall of the cover plate 2.

[0022] The above scheme is adopted: when not affected by external force, the connecting spring 304 keeps the slider 306 and the pull rod 305 on the left side of the fixed block B303 due to its own elastic force. At this time, the rotating shaft 301 is plugged into the inner wall of the slider 306. There are two groups of grooves 309 on the slider 306. When the cover 2 is closed, the protrusion 308 is engaged with a group of grooves 309 in the horizontal direction. When the cover 2 needs to be opened, the pull rod 305 can be pulled to the right to drive the slider 306 to move outward, and the connecting spring 304 can be pulled to the right to drive the slider 306 to move outward. The spring 304 is forced to contract, so that the groove 309 and the protrusion 308 are out of contact, and the cover 2 can be flipped upward, driving the rotating shaft 301 to rotate, and the spiral spring 307 is forced to contract. When the cover 2 is flipped ninety degrees, the pull rod 305 can be loosened, and the connecting spring 304 causes the pull rod 305 and the slider 306 to move to the left due to its own elastic force. At this time, the protrusion 308 is engaged with a group of grooves 309 in the vertical direction, so that the cover 2 can be kept in a vertical state, and the shell 1 can be opened so that the internal components can be maintained.

[0023] When the maintenance is completed, the operator can pull the pull rod 305 to the right to disengage the groove 309 from the protrusion 308. Under the elastic force of the spiral spring 307, the cover 2 and the rotating shaft 301 are synchronously flipped downward, thereby automatically closing the shell 1. After closing, the pull rod 305 is released, and under the elastic force of the connecting spring 304, the protrusion 308 is engaged with the horizontal groove 309 to maintain the closed state. Therefore, there is no need to turn the bolt multiple times to open or close the cover 2, which is more convenient and quick, and improves the efficiency of maintenance.

[0024] like Figure 6 As shown, the adjustment mechanism 6 includes a moving plate 601, the inner wall of the moving plate 601 is elastically connected to a clamping block 603 through a telescopic spring 602, the inner wall of the moving plate 601 is rotatably connected to a threaded rod 605, the outer wall of the threaded rod 605 is threadedly connected to a fixed plate 604, and the outer wall of the base 5 is provided with a clamping groove 606; the moving plate 601 is slidably connected to the inner wall of the base 5, the clamping block 603 is slidably connected to the inner wall of the moving plate 601, and the fixed plate 604 is slidably connected to the inner wall of the moving plate 601; one end of the telescopic spring 602 is fixedly connected to the outer wall of the clamping block 603, and the other end of the telescopic spring 602 is fixedly connected to the inner wall of the moving plate 601, and the clamping block 603 is clamped in the clamping groove 606.

[0025] By adopting the above scheme, bolts can be passed through the two groups of through grooves provided on the fixing plate 604 and connected to the threaded holes on the device, so that the base 5 can be fixed on the device, and the installation and fixation of the shell 1 can be completed; and when the position of the bolt on the device is different from the position of the fixing plate 604 and the bolt cannot be installed, the clamping block 603 can be pressed downward, the telescopic spring 602 is forced to shrink, and the clamping block 603 is disengaged from the group of clamping grooves 606, so that the limit of the movable plate 601 can be released and the movable plate 601 can be moved; then the threaded rod 605 can be rotated, and since the threaded rod 605 and the fixing plate 60 4 is threadedly connected, and the fixed plate 604 is slidably connected to the inner wall of the movable plate 601. In the process of rotating the threaded rod 605, the fixed plate 604 will move horizontally, thereby changing the position of the through slot, and combined with the movement of the movable plate 601, the through slot can be adjusted to correspond to the position of the bolt on the device, and the elastic force of the telescopic spring 602 drives the clamping block 603 to clamp with the corresponding clamping slot 606, and the position of the adjustment mechanism 6 is fixed, and the housing 1 can be installed and fixed by bolts, which improves adaptability and can be installed on devices of different specifications and different bolt positions, which is more flexible.

[0026] like Figure 5 As shown, the buffer mechanism includes a round rod 801, the outer wall of the round rod 801 is fixedly connected to a rubber pad 802, the outer wall of the bottom end of the moving block 4 is hinged to a damping ring 803 through a connecting rod 804, and the inner wall of the base 5 is fixedly connected to a buffer spring 805; the round rod 801 is fixedly connected to the inner wall of the base 5, the rubber pad 802 is in contact with the inner wall of the damping ring 803, and the moving block 4 is slidably connected to the inner wall of the base 5; one end of the connecting rod 804 is hinged to the damping ring 803, and the other end of the connecting rod 804 is hinged to the outer wall of the bottom end of the moving block 4, and the buffer spring 805 is fixedly connected to the outer wall of the bottom end of the moving block 4.

[0027] The above scheme is adopted: when the base 5 is fixed on the equipment and the equipment is running, vibration will be generated and transmitted to the base 5 and the shell 1. When the shell 1 is vibrated, the moving block 4 will move up and down in the inner wall of the base 5 due to the vibration, so that the buffer spring 805 will continuously shrink and rebound to reset, and the moving block 4 will drive the connecting rod 804 to flip. Since the position where the top of the connecting rod 804 is connected to the moving block 4 is fixed, and the damping ring 803 can move on the outer wall of the round rod 801, the two groups of damping rings 803 will continuously move laterally when the moving block 4 moves. The inner wall of the damping ring 803 is provided with a rubber ring. When moving, the rubber ring continuously contacts with multiple groups of rubber pads 802, which can increase friction and slow down the travel of the damping ring 803, thereby reducing the amplitude of the vibration of the moving block 4, and then achieving a better buffering effect, which greatly reduces the vibration of the shell 1 and its internal components, and reduces the possibility of damage to the internal components due to vibration, resulting in inability to use normally.

[0028] The working principle and use process of the present invention: First, the base 5 is fixed to the device through the adjustment mechanism 6, and the bolts are passed through the through slots and connected to the threaded holes on the device through the two groups of through slots on the fixing plate 604 to complete the installation and fixation of the shell 1. When the bolt position on the device is different from the through slot position on the fixing plate 604 and cannot be installed, the block 603 can be pressed downward to force the telescopic spring 602 to shrink, and the block 603 is out of contact with the slot 606, so that the limit of the movable plate 601 is released, and the movable plate 601 is moved along the outer wall of the base 5. Then, the threaded rod 605 is rotated to make the fixing plate 604 move laterally in the inner wall of the movable plate 601. The position of the through slot on the fixing plate 604 can be adjusted to move the through slot to correspond to the bolt position on the device, and the elastic force of the telescopic spring 602 drives the block 603 to pop out and engage with the corresponding slot 606, so that the position of the adjustment mechanism 6 can be fixed, and the base 5 can be installed on the device through the bolt, so that when the bolt position is different due to different specifications of the equipment, it can also be installed and fixed, thereby improving the adaptability and flexibility of the device.

[0029] After the installation is completed, the circuit can be connected, which is the existing technology, and the cover 2 can be closed for use; when the cover 2 needs to be opened for maintenance of the internal components of the shell 1, the pull rod 305 can be pulled to the right, driving the slider 306 to move outward, and the connecting spring 304 is forced to shrink, so that the groove 309 and the protrusion 308 are out of contact, and the cover 2 can be flipped upward, driving the rotating shaft 301 to rotate, and the volute spring 307 is forced to shrink. After the cover 2 is flipped ninety degrees, the pull rod 305 is released, and the connecting spring 304 causes the pull rod 305 and the slider 306 to move to the left. At this time, the protrusion 308 is in contact with the vertical square. The cover 2 is locked with a set of grooves 309 in the horizontal direction to keep the cover 2 in a vertical state, so that the internal components of the shell 1 can be maintained; after the maintenance is completed, the pull rod 305 is pulled to the right to make the groove 309 disengage from the protrusion 308, and under the elastic force of the spiral spring 307, the cover 2 and the rotating shaft 301 are synchronously flipped downward to automatically close the shell 1. After closing, the pull rod 305 is released, and the connecting spring 304 drives the slider 306 to reset, so that the protrusion 308 is locked with the horizontal groove 309 to keep the closed state, so that the cover 2 can be opened or closed without turning the bolts multiple times, which is convenient and quick, and improves maintenance efficiency.

[0030] When the equipment is running, vibration will be generated and transmitted to the base 5 and the shell 1. When the shell 1 is vibrated, the moving block 4 will move up and down in the inner wall of the base 5, causing the buffer spring 805 to continuously shrink and rebound to reset. At the same time, the moving block 4 drives the connecting rod 804 to flip, driving the two groups of damping rings 803 to continuously move laterally on the outer wall of the round rod 801. The rubber ring on the inner wall of the damping ring 803 is constantly in contact with the multiple groups of rubber pads 802 on the outer wall of the round rod 801, increasing the friction force and slowing down the moving stroke of the damping ring 803, thereby reducing the vibration amplitude of the moving block 4, achieving a better buffering effect, greatly reducing the vibration of the shell 1 and its internal components, and reducing the possibility of internal components being damaged by vibration and unable to be used normally.
