Description

Technical Field

[0001] The utility model relates to the technical field of floor spring processing, in particular to a positioning component for a floor spring oiling machine. Background Art

[0002] Floor springs are hydraulic door closers widely used in modern building hardware, primarily for controlling the automatic closing of doors. After assembly, floor springs require oiling before testing their door closing function. To improve the efficiency of floor spring oiling, a dedicated oiling machine is available. Multiple floor springs are clamped on the machine's workbench. The machine's lifting mechanism moves multiple oiling nozzles downward, connecting them to the floor springs and the oil supply system to fill the floor springs with oil. After oiling is complete, the oiling mechanism moves the multiple oiling nozzles upward and resets, completing the oiling of the floor springs.

[0003] However, after completing one floor spring oiling operation and before starting the next oiling operation, it is necessary to remove multiple floor springs on the workbench that have completed oiling, and then install multiple floor springs that have not been oiled, which makes the waiting time between two adjacent oiling operations long and reduces the oiling efficiency; in addition, the space between the oiling nozzle and the workbench for clamping and removing the floor spring is small, making clamping and removing the floor spring difficult. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a positioning assembly for a floor spring oiling machine, which can improve the oiling efficiency and reduce the difficulty of clamping and removing the floor spring for operators.

[0005] In order to solve the above technical problems, the utility model provides a positioning assembly for a floor spring oiling machine, including a base for being installed on the floor spring oiling machine, a clamping seat for slidingly connecting to the middle part of the base and for clamping multiple floor springs, a detection device arranged on the rear side of the middle part of the base and for detecting the clamping seat, a locking device installed in the base for locking the clamping seat, and a reset device installed at the rear part of the base and for pushing the clamping seat back to the front part of the base, the locking device including a locking rod connected to the base for sliding up and down and a lifting drive mechanism for driving the locking rod to move up and down, a locking hole is provided on the lower side of the clamping seat, the position of which corresponds to the locking rod and the contour of which matches, the detection device, the lifting drive mechanism and the reset device are communicatively connected.

[0006] As an improvement to the above solution, the upper portion of the locking rod is a frustum with an outer diameter that gradually decreases from bottom to top, and the contour of the locking hole matches the contour of the upper portion of the locking rod.

[0007] As an improvement to the above solution, the upper side of the locking rod is further provided with a spherical crown-shaped protrusion that is tangent to the outer side surface of the locking rod, and the clamping seat is provided with a cavity that is connected to the locking hole and is used to accommodate the protrusion.

[0008] As an improvement to the above-mentioned solution, the base is provided with a mounting groove for placing the lifting drive mechanism, and the locking device also includes a linkage plate installed at the output end of the lifting drive mechanism and placed in the mounting groove, and multiple locking rods are fixed on the upper side of the linkage plate, and the lower side of the clamping seat is provided with multiple locking holes arranged one-to-one corresponding to the multiple locking rods.

[0009] As an improvement of the above solution, the detection device includes a support block fixed on the base, a pressure sensor installed on the front side of the support block, and a contact plate installed on the front side of the pressure sensor. The pressure sensor is communicatively connected to the reset device.

[0010] As an improvement of the above-mentioned scheme, the detection device includes two support blocks spaced apart on the left and right, two pressure sensors spaced apart on the left and right, and a contact plate installed in front of the two pressure sensors. The reset device is arranged between the two support blocks and the two pressure sensors, and a clearance hole is provided in the middle of the contact plate for the reset device to pass through.

[0011] As an improvement to the above solution, the base is provided with two C-shaped slide grooves extending forward and backward and arranged opposite to each other, and the left and right sides of the clamping seat are correspondingly slidably connected to the two C-shaped slide grooves.

[0012] As an improvement to the above solution, a push handle is provided on the front side of the clamping seat for driving the clamping seat to slide relative to the base.

[0013] The implementation of this utility model has the following beneficial effects:

[0014] The positioning assembly for the floor spring oiling machine of the utility model cooperates with each other through the base, the clamping seat, the detection device, the locking device and the reset device. The oiling machine can remove the floor spring that has been oiled and clamp the floor spring that has not been oiled on the other clamping seat, thereby reducing the waiting time between two adjacent oiling operations and improving the oiling efficiency. In addition, the clamping seat provides more space for the operator to operate, which reduces the difficulty of the operator in clamping and removing the floor spring.

[0026] The following is a further description of the present invention in conjunction with the accompanying drawings and specific embodiments to facilitate a clearer understanding of the technical concept claimed in the present invention. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear in the present invention are based solely on the drawings and are not intended to limit the present invention.

[0027] like Figures 1 to 5As shown, a positioning assembly for a floor spring oiling machine in an embodiment of the utility model includes a base 100 for installation on the floor spring oiling machine, a clamping seat 200 for slidingly connecting with the middle part of the base 100 and for clamping multiple floor springs, a detection device 300 arranged on the rear side of the middle part of the base 100 and for detecting the clamping seat 200, a locking device 400 installed in the base 100 for locking the clamping seat 200, and a reset device 500 installed at the rear part of the base 100 and used to push the clamping seat 200 back to the front part of the base 100. In fact, the base 100 is a component of the positioning assembly of the utility model for installation and connection with the floor spring oiling machine, so that the positioning assembly of the utility model serves as a workbench of the floor spring oiling machine, and the clamping seat 200 clamps multiple floor springs and cooperates with the oiling machine to perform oiling operations on multiple floor springs; the clamping seat 200 is used to clamp multiple floor springs (the clamping mechanism and positioning mechanism on the clamping seat 200 are omitted in the drawings of the embodiment of the utility model), and can drive multiple floor springs to move forward and backward relative to the base 100 and leave the base 100; the detection device 300 can be a distance sensor for detecting the front and rear position of the clamping seat 200 or a micro switch for abutting against the rear side of the clamping seat 200 to detect the front and rear position of the clamping seat 200 Whether the position reaches the required position, the clamping seat 200 is positioned to ensure that the oiling nozzle of the oiling machine can be aligned with the oiling hole of the floor spring; when the front and rear position of the clamping seat 200 reaches the required position, the locking device 400 is actuated to fix the relative position of the clamping seat 200 and the base 100, preventing the clamping seat 200 from continuing to move forward and backward relative to the base 100, thereby ensuring the positioning accuracy of the clamping seat 200; when the oiling machine has completed oiling, the locking device 400 releases the lock on the clamping seat 200; the reset device 500 can be a cylinder, a hydraulic push rod, etc., which can push the clamping seat 200 forward, so that the clamping seat 200 slides forward, thereby preventing the oiling nozzle of the oiling machine from affecting the operator's installation or removal of the floor spring on the clamping seat 200.

[0028] The locking device 400 includes a locking rod 410 that is slidably connected to the base 100 and a lifting drive mechanism 420 for driving the locking rod 410 to move up and down. The lower side of the clamping seat 200 is provided with a locking hole 210 whose position corresponds to the locking rod 410 and whose contour matches that of the locking rod 410. The detection device 300, the lifting drive mechanism 420 and the reset device 500 are communicatively connected. In fact, the lifting drive mechanism 420 can be a cylinder, a hydraulic push rod, etc., which can drive the locking rod 410 to move up and down; when the front and rear positions of the clamping seat 200 reach the required position, the detection device 300 sends a working signal to the lifting drive mechanism 420, and the lifting drive mechanism 420 drives the locking rod 410 to move upward and extend into the locking hole 210, thereby achieving the locking of the front and rear positions of the clamping seat 200; when the oil filling is completed, the lifting mechanism drives the locking rod 410 to move downward and leave the locking hole 210, contacting the lock of the clamping seat 200, and sending a signal to the reset device 500, and the reset device 500 pushes the clamping seat 200 forward. When the oiling machine is oiling multiple floor springs on the clamping seat 200, the oiled floor spring can be removed from another clamping seat 200 and an unoiled floor spring can be clamped. After the oiling is completed and the clamping seat 200 is pushed out, the operator can manually replace the clamping seat 200 with another clamped floor spring or add a replacement robot to replace it, and then the next oiling operation can be carried out. In order to achieve communication between the detection device 300, the lifting drive mechanism 420 and the reset device 500, the detection device 300, the lifting drive mechanism 420 and the reset device 500 can all be electrically connected to a controller such as a programmable logic control unit, an industrial computer, a single board computer, a fieldbus control system, etc. that is added or installed in the oiling machine. The structure and working principle of the controller will not be detailed here.

[0029] It should be noted that the base 100 is preferably provided with two C-shaped slots 120 extending forward and backward and arranged in opposing relation. The left and right sides of the clamping seat 200 are slidably connected to the two C-shaped slots 120. The C-shaped slots 120 enable the clamping seat 200 to slide forward and backward with the base 100 and prevent the clamping seat 200 from swinging left and right. The front side of the clamping seat 200 is preferably provided with a push handle 230 for driving the clamping seat 200 to slide relative to the base 100, allowing a worker to manually push the clamping seat 200 forward relative to the base 100.

[0030] The positioning assembly for the floor spring oiling machine in the utility model cooperates with each other through the base 100, the clamping seat 200, the detection device 300, the locking device 400 and the reset device 500. It can remove the oiled floor spring from the other clamping seat 200 of the oiling machine and clamp the unoiled floor spring, thereby reducing the waiting time between two adjacent oiling operations and improving the oiling efficiency. In addition, the clamping seat 200 provides more space for the operator to operate, reducing the difficulty of the operator in clamping and removing the floor spring.

[0031] Specifically, the upper portion of the locking rod 410 is preferably a conical portion with a gradually decreasing outer diameter from bottom to top, and the contour of the locking hole 210 matches the contour of the upper portion of the locking rod 410. Since the clamping base 200 may have a certain degree of fore-aft position error after forward and backward movement, the conical upper portion of the locking rod 410 matches the locking hole 210, thereby correcting this error under the guidance of the locking hole 210 and ensuring the positioning accuracy of the clamping base 200.

[0032] More specifically, the upper side of the locking rod 410 is preferably provided with a spherical crown-shaped projection 411 that is tangential to the outer side of the locking rod 410. The clamping seat 200 is provided with a cavity 220 that communicates with the locking hole 210 and is used to accommodate the projection 411. Specifically, the lower side of the projection 411 is identical to and coincides with the upper side of the locking rod 410. The outer side of the projection 411 is tangential to the outer side of the upper portion of the locking rod 410. Contacting the locking hole 210 via a spherical surface instead of a flat surface increases the guiding range of the upper portion of the locking rod 410, enabling correction of errors over a wider range.

[0033] Specifically, the base 100 is preferably provided with a mounting slot 110 for accommodating the lifting drive mechanism 420. The locking device 400 further includes a linkage plate 430 mounted at the output end of the lifting drive mechanism 420 and positioned in the mounting slot 110. A plurality of locking rods 410 are fixed to the upper side of the linkage plate 430. The lower side of the clamping seat 200 is provided with a plurality of locking holes 210 corresponding to the plurality of locking rods 410. The one-to-one correspondence between the plurality of locking rods 410 and the plurality of locking holes 210 ensures that the locking device 400 locks the clamping seat 200.

[0034] It should be noted that the detection device 300 preferably includes a support block 310 fixed to the base 100, a pressure sensor 320 installed on the front side of the support block 310, and a contact plate 330 installed on the front side of the pressure sensor 320. The pressure sensor 320 is in communication with the reset device 500. In fact, when the rear side of the clamping seat 200 contacts the contact plate 330, the front and rear positions of the clamping seat 200 reach the desired position, that is, the contact plate 330 plays the role of positioning the rear side of the clamping seat 200; in order to increase the contact area between the clamping seat 200 and the contact plate 330, the rear side of the clamping seat 200 can be a vertical plate. When the rear side of the clamping seat 200 contacts the contact plate 330, the pressure sensor 320 is pressurized to produce a micro-deformation and detect data, that is, the clamping seat 200 is in place, realizing the function of the detection device 300 to detect the clamping seat 200 and preventing the clamping seat 200 from continuing to move backward after it is in place.

[0035] Furthermore, the detection device 300 preferably includes two support blocks 310 spaced apart from each other, two pressure sensors 320 spaced apart from each other, and a contact plate 330 mounted in front of the two pressure sensors 320. The reset device 500 is disposed between the two support blocks 310 and the two pressure sensors 320, and a clearance hole 331 is provided in the middle of the contact plate 330 for the reset device 500 to pass through. By providing two support blocks 310 spaced apart from each other, two spaced apart from each other, and the clearance hole 331, the left and right range covered by the contact plate 330 can be increased, while leaving clearance space for the reset device 500, ensuring that the reset device 500 can push the clamping seat 200 forward and slide out.

[0036] The above are only specific embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
