Description

Technical Field

[0001] This application relates to the technical field of shock absorber assembly, and particularly to a double-station spring pressing device for shock absorbers. Background Art

[0002] A shock absorber is a shock-absorbing component used in automobiles and motorcycles. Conventional shock absorber components include components such as a spring pull rod, a pull rod nut, and a threaded joint. In the spring pressing process, it is necessary to sleeved the pull rod nut outside the spring pull rod, compress the spring on the spring pull rod, and then thread the threaded joint with the thread at the lower end of the spring pull rod so that the spring pull rod remains in an energy storage state. In addition, in order to enhance the stability of the connection between the threaded joint and the spring pull rod, it is also necessary to apply a fastening adhesive at the threaded joint.

[0003] The pressing devices in the prior art mainly drive the pressing block to press down through a cylinder or a motor to press the spring pull rod to keep it in an energy storage state, and then manually apply glue to the threaded joint and screw it onto the end of the spring pull rod by hand. For example, Chinese Patent CN208051311U discloses an automatic pressing device for automobile shock absorbers, which includes a frame, and a fixture for fixing a workpiece is detachably arranged on the frame, and a pressing block and a servo motor for driving the pressing block to press down are arranged above the fixture. The above pressing device has the following defects in actual application:

[0004] First, the device can only perform the pressing action. The operator needs to manually screw the threaded joint from the lower end of the spring pull rod, which affects the pressing efficiency of the shock absorber. More importantly, the threaded port of the spring pull rod is located at the lower end, usually below the operator's line of sight. When the operator manually screws the threaded joint, he often needs to bend down and get close to observe the position of the threaded port to align and screw the threaded joint with the threaded port. During this process, the spring pull rod remains in an energy storage state under the pressing action of the pressing block. If phenomena such as loosening of the fixture and the pressing block cause the spring pull rod to shift, it is very easy for the spring pull rod to pop out and injure the operator, there are certain safety hazards.

[0005] Second, the spring pull rod is only clamped and fixed by a conventional fixture without being corrected. When the axial direction of the spring pull rod deviates from the pressing direction of the pressing block, it will not only cause the spring pressing to deviate, affecting the quality of the shock absorber product, but also easily cause movement interference, resulting in damage to the fixture or damage to the pressing block and the motor.

[0006] Third, the device can only press one tooling at a time, and the pressing efficiency is low. Summary of the Utility Model

Detailed implementation manners

[0032] As Figures 1-4 shown, a double - station spring pressing device for shock absorbers according to the present application is used to press - fit the spring pull rod, pull rod nut and threaded joint of the shock absorber into one body.

[0033] The double - station spring pressing device for shock absorbers includes a frame 10. The frame 10 is in the shape of a square frame body, and there are two pressing stations on the front surface of the frame 10. Define the axial direction (usually the vertical direction) of the spring pull rod during standard pressing as the first direction, the radial direction (i.e., the horizontal direction) as the second direction, and the circumferential direction as the third direction.

[0034] At each pressing station, a pressing module is provided. The pressing module includes a pull rod fixing mechanism 20, a pressing mechanism 30, a centering mechanism 40, a tray mechanism 50, a nut fixing mechanism 60 and a screwing mechanism 70.

[0035] The pull rod fixing mechanism 20 is arranged at one end of the pressing station. Specifically, it is located at the upper end of the pressing station. The pull rod fixing mechanism 20 specifically includes a back plate, and the back plate extends outward to form an extended cross - beam. A pull rod groove adapted to the spring pull rod and used for the spring pull rod to be embedded is provided on the cross - beam. Specifically, the shape and size of the pull rod groove are adapted to the shape and size of a section of the spring pull rod, so that a section of the spring pull rod can be embedded into the pull rod groove to achieve preliminary fixation.

[0036] The pressing mechanism 30 is arranged corresponding to the pull rod groove. Specifically, it is arranged directly above the pull rod groove. The pressing mechanism 30 includes a pressing block 301 and a first driving member 302. The pressing block 301 is in the shape of a square block structure. The pressing block 301 is slidably arranged on the frame 10. Specifically, the pressing block 301 can be slidably connected to the frame 10 through a slide rail, so that the pressing block 301 has the freedom of movement to slide in the first direction, that is, the pressing block 301 can slide up and down relative to the frame 10. The first driving member 302 is linked with the pressing block 301 and is used to provide power to drive the pressing block 301 to slide up and down.

[0037] The aligning mechanism 40 includes aligning blocks 401 and second driving members 402. The number of aligning blocks 401 is two, and the two aligning blocks 401 are arranged opposite to each other left and right on both sides of the pull rod groove in the second direction, and both aligning blocks 401 are slidably connected to the frame 10, so that the aligning blocks 401 have the degree of freedom of movement to slide in the second direction, that is, the left and right direction. The second driving members 402 are linked with the aligning blocks 401 and are used to drive the two aligning blocks 401 to slide. Specifically, the number of the second driving members 402 can be two, which are arranged in one-to-one correspondence with the aligning blocks 401, and the two second driving members 402 respectively drive the two aligning blocks 401 to slide. On the side of the aligning block 401 facing the pull rod groove, an aligning groove adapted to the outer wall of the spring pull rod is provided, and the aligning groove extends along the first direction, that is, the vertical direction. After the spring pull rod is inserted into the pull rod groove, the second driving members 402 drive the two aligning blocks 401 to slide towards each other. When the aligning blocks 401 slide to fit the outer surface of the spring pull rod, the two aligning blocks 401 clamp the spring pull rod from the left and right sides respectively. At this time, due to the structural feature that the aligning groove extends along the vertical direction, the two aligning blocks 401 can cooperate to align the spring pull rod and ensure that the spring pull rod is in a vertical state. Thus, when the pressing block 301 presses down vertically, it can ensure that the axial direction of the spring pull rod is consistent with the pressing direction of the pressing block 301 and avoid deviation.

[0038] The tray mechanism 50 is arranged at one end of the pressing station far from the pressing mechanism, that is, the lower end. The tray mechanism 50 includes a movable tray 501 and a third driving member 502. Specifically, the movable tray 501 is in a semi-circular disk shape, and the number of the movable trays 501 is two. The two movable trays 501 are arranged opposite to each other on both sides of the pressing station in the second direction, that is, the left and right sides, and both movable trays 501 are slidably connected to the frame 10, so that the movable tray 501 has the degree of freedom of movement to slide in the second direction, that is, the left and right direction. The third driving members 502 are also arranged in two, corresponding to the two movable trays 501 respectively, and are used to drive the two movable trays 501 to slide left and right. The movable tray 501 has a pull rod nut groove adapted to the pull rod nut for the pull rod nut to be inserted. Specifically, the pull rod nut groove is located on the upper end surface of the movable tray 501 and extends from top to bottom. The shape and size of the pull rod nut groove are adapted to the pull rod nut. When the two movable trays 501 move towards each other and get close, the left and right parts of the pull rod nut can be respectively inserted into the pull rod nuts of the two movable trays 501 to realize the preliminary fixation of the pull rod nut.

[0039] The nut fixing mechanism 60 is arranged at one end of the tray mechanism 50 away from the pressing mechanism 30, that is, below the tray mechanism 50. The nut fixing mechanism 60 includes a movable clamp 601 and a fourth driving member 602. Specifically, after the pull rod nut is embedded in the movable tray 501, the lower end will protrude outside the movable tray 501. The number of the movable clamps 601 is two, and the two movable clamps 601 are respectively arranged on both sides of the press-fitting station in the second direction, that is, the two movable clamps 601 are oppositely arranged on the left and right sides below the movable tray 501. Both of the two movable clamps 601 are slidably connected to the frame 10, so that the movable clamp 601 has a degree of freedom of movement in the second direction, that is, sliding left and right, so that the two movable clamps 601 can approach each other or move away from each other. The number of the fourth driving members 602 is two, which are respectively arranged corresponding to the two movable clamps 601 and are used to drive the two movable clamps 601 to slide respectively. A clamping groove adapted to the exposed part of the pull rod nut is formed on the inner side surface of the movable clamp 601. When the two movable clamps 601 move to fit together under the drive of the fourth driving member 602 left and right, the exposed part of the pull rod nut can be clamped and fixed, so as to fix the pull rod nut.

[0040] The screwing mechanism 70 is arranged at one end of the nut fixing mechanism 60 away from the tray mechanism 50, that is, the lower end, and corresponds to the pull rod fixing mechanism 20. The screwing mechanism 70 includes a sliding seat, a screwing head, a fifth driving member and a sixth driving member. In the figure, the fifth driving member and the sixth driving member are respectively embedded in the frame 10 and the sliding seat and are not shown. Specifically, the sliding seat is in the shape of a square seat body and is slidably connected to the frame 10, so that the sliding seat has a degree of freedom of movement in the first direction, that is, up and down.

[0041] The fifth driving member is linked with the sliding seat and is used to drive the sliding seat to slide up and down. The screwing head is rotatably arranged on the sliding seat. Specifically, it is arranged on the upper end surface of the sliding seat. The screwing head is in the shape of a disc and is rotatably connected to the sliding seat by means of hole-shaft cooperation, so that the screwing head can rotate relative to the sliding seat in the third direction, that is, the circumferential direction of the spring pull rod. On the surface of the screwing head facing the pull rod groove, that is, the upper end surface, a joint groove adapted to the threaded joint and used for the threaded joint to be embedded is formed. Specifically, the shape and size of the joint groove are both adapted to the threaded joint, and the threaded joint can be embedded into the joint groove for fixation. The sixth driving member is linked with the screwing head and is used to drive the screwing head to rotate, and then the threaded joint on the screwing head can be driven to rotate, so as to screw the threaded joint onto the lower end of the spring pull rod.

[0042] Further, in this embodiment, the shock absorber double-station spring pressing equipment further includes a dispensing mechanism 80. The dispensing mechanism 80 includes a dispensing head 801 and a seventh driving member 802. The dispensing head 801 is connected to a fastening glue source through a pipeline, for example, a container storing fastening glue. The dispensing head 801 is slidably connected to the frame 10, so that the dispensing head 801 has a degree of freedom of movement in the direction of approaching or departing from the screwing mechanism 70. Exemplarily, the dispensing head 801 is disposed beside the screwing mechanism 70 obliquely to the tabletop of the frame 10 and is slidably connected to the frame 10 through an inclined slide rail, so that the dispensing head 801 can slide obliquely downward along the slide rail to approach the screwing mechanism 70 for dispensing, and can retreat along the original path to a position far from the screwing mechanism 70 after the dispensing is completed. The seventh driving member 802 is slidably connected to the dispensing head 801 and is used to provide power to drive the dispensing head 801 to reciprocally slide along the aforementioned slide rail to complete the forward dispensing and retreat actions. By providing an automated dispensing mechanism 80, manual dispensing is not required, and the efficiency and automation degree of the spring pull rod pressing process can be further improved.

[0043] Further, in this embodiment, the shock absorber double-station spring pressing equipment further includes a controller. Exemplarily, the controller can be a commonly used industrial controller such as a PLC (Programmable Logic Controller) or an MCU (Microcontroller Unit). In this embodiment, it is used for simple start-stop control. The controller is respectively signal-connected to the first driving member 302, the second driving member 402, the third driving member 502, the fourth driving member 602, the fifth driving member, the sixth driving member, and the seventh driving member 802, and is used to control the start and stop of each driving member according to the production steps. In other preferred embodiments, a display screen and control buttons can also be installed on the frame 10 and are respectively signal-connected to the controller, so as to facilitate the operator to input control instructions and observe the operating status of the equipment.

[0044] Further, in this embodiment, the shock absorber double-station spring pressing equipment further includes a start switch 90 and a warning lamp 100. Both the start switch 90 and the warning lamp 100 are signal-connected to the controller. Specifically, the start switch 90 is disposed on the side of the frame 10 close to the operator, and the warning lamp 100 is disposed on the top of the frame 10. When the operator presses the start switch 90, a start signal is input to the equipment, and the controller controls each driving member to perform actions to complete the pressing process. The controller is signal-connected to the warning lamp 100 and is used to output an alarm signal when the equipment reports an error or fails, causing the warning lamp 100 to light up to prompt the operator.

[0045] Further, in this embodiment, the shock absorber double-station spring pressing device further includes a safety door (not labeled in the figure). The safety door is arranged on the side of the pressing station close to the operator. Exemplarily, the safety door can be an infrared fence, including a strip-shaped transmitter and a receiver. The transmitter and the receiver are oppositely arranged on both sides of the operation side of the pressing station. The safety door is signal-connected to the controller. Under normal conditions, the receiver can continuously receive the infrared signal emitted by the transmitter. When the safety door detects that a human body enters the sensing area, the infrared signal is blocked, and the infrared signal received by the receiver is interrupted, and an interruption signal is transmitted to the controller. After receiving the interruption signal, the controller stops the device to avoid the pressing action from hurting the human body entering the sensing area. By setting the safety door, the safety of the production process can be further improved.

[0046] Further, in this embodiment, on the surface of the pressing block 301 facing the pull rod groove, that is, the lower end surface, a pressing groove adapted to the end of the spring pull rod is provided. Specifically, a groove is formed by upward depression in the middle of the lower end surface of the pressing block 301. The size of the groove is slightly larger than the end of the spring pull rod and corresponds to the position of the end of the spring pull rod during pressing. During pressing, the end of the spring pull rod is embedded into the pressing groove, so that the pressing block 301 can stably press the spring pull rod and avoid relative displacement between the pressing block 301 and the spring pull rod during the pressing process.

[0047] Further, in this embodiment, the alignment groove is a trapezoidal groove. Specifically, the end of the alignment groove facing the pull rod fixing mechanism 20 is an open structure, and the width of the alignment groove gradually decreases along the direction away from the pull rod fixing mechanism 20, so that the spring pull rod can enter the alignment groove from the side during alignment. The inner side surfaces of the alignment groove are all flat surfaces extending along the first direction. When the alignment blocks 401 clamp the spring pull rod from the side, the two alignment blocks 401 cooperate to align the spring pull rod so that its axis is in the same direction as the first direction, avoiding direction deviation during the pressing process.

[0048] Further, in this embodiment, the first driving member 302, the second driving member 402, the third driving member 502, the fourth driving member 602, the fifth driving member, and the seventh driving member 802 are all linear cylinders, which are used to drive the corresponding actuators to perform linear reciprocating motions, and the sixth driving member is a motor, which is used to drive the screwing head to perform rotational motion. The above-mentioned driving members have the advantages of simple application, easy installation, and stable driving.

[0049] The working process of the shock absorber double-station spring pressing device of this embodiment will be fully described below in combination with the above content:

[0050] The third driving member 502 drives the two movable trays 501 to move closer to each other. The operator sequentially installs the tie rod nut and the threaded joint onto the movable tray 501 of the tray mechanism 50 and the screwing head of the screwing mechanism 70, and then installs the spring tie rod into the tie rod groove of the tie rod fixing mechanism 20 for preliminary fixing. At this time, the tie rod nut is sleeved outside the spring tie rod. The operator's hand exits the press-fitting station, and presses the start switch 90. The controller controls the actions of each mechanism.

[0051] First, the second driving member 402 drives the two centering blocks 401 to move closer to each other until they fit against the outer side wall of the spring tie rod, so that the outer side wall of the spring tie rod is embedded into the centering groove. Under the combined action of the two centering blocks 401, the spring tie rod is centered to ensure that the axial direction of the spring tie rod and the press-fitting direction of the pressing block 301 are both the first direction.

[0052] Then, the first driving member 302 drives the pressing block 301 to press down until the spring tie rod is embedded into the pressing groove. After the pressing block 301 presses down to the specified position, it remains fixed. At this time, the spring tie rod is in an energy storage state. The fourth driving member 602 drives the movable clamps 601 to move closer to each other until the two movable clamps 601 cooperate to clamp the tie rod nut, so that the tie rod nut remains in a fixed state.

[0053] The seventh driving member 802 drives the dispensing head 801 to approach the threaded joint and dispense glue. After the dispensing is completed, it retracts to the original position. The fifth driving member drives the sliding seat to slide upward, and at the same time, the sixth driving member drives the screwing head to rotate. When the threaded joint contacts the threaded port at the lower end of the spring tie rod, the threaded joint will be screwed with the threaded port until the screwing is completed. Then, the fifth driving member drives the sliding seat to move downward. Since the threaded joint is already connected to the spring tie rod through the thread and the fastening glue, at this time, the threaded joint will separate from the screwing head, and the screwing head retracts to the original position. The pressing block 301, the centering block 401, the movable tray 501, and the movable clamp 601 each retract to the original position under the drive of the corresponding driving member. The operator can remove the spring tie rod from the tie rod groove, and the press-fitting is completed.

[0054] In the actual production process, since it takes a certain amount of time for the equipment to complete the automatic press-fitting, after the operator installs a spring tie rod into a press-fitting station for automatic press-fitting, during the process of waiting for the equipment to perform automatic press-fitting, another spring tie rod can be synchronously installed into another station. Thus, the synchronous press-fitting of the two stations can be achieved, improving the production efficiency.

[0055] This application can automatically complete the press-fitting of the spring tie rod and the screwing of the threaded joint, which is beneficial to improving the press-fitting efficiency and safety during the press-fitting process of the spring tie rod.
