Description

Technical Field

[0001] The utility model relates to a press-fitting device, in particular to a selection and press-fitting device for a clutch retaining spring of an automobile. Background Art

[0002] The automobile clutch is an important part of the automobile. The automobile clutch (workpiece) includes a gear plate, a center shaft, a circlip, a sleeve and a spring. The gear plate is provided with a center shaft, and a sleeve is installed on the center shaft through a circlip. A spring is provided between the sleeve and the gear plate. The installation of the circlip is generally carried out by press-fitting, which includes manual press-fitting and mechanical press-fitting. Manual press-fitting is not only labor-intensive, but also has differences due to individual differences, resulting in uneven quality of finished products.

[0003] The patent application with announcement number CN103624529A discloses a clutch booster retaining spring feeding and pressing device and a pressing method, which includes a machine base provided with a positioning assembly, a pressing mechanism provided with a pressure head opposite to the positioning assembly, a pre-pressing guide mechanism located between the positioning assembly and the pressing mechanism, and a feeding mechanism for feeding the retaining spring to the lower side of the pressure head. The pre-pressing guide mechanism can overcome the problem that the components inside the clutch booster are higher than the upper end surface of the housing under the action of the pressure spring before pressing, and the conventional retaining spring pressing device is difficult to press and has low efficiency when pressing the retaining spring of the clutch booster; the clutch booster retaining spring feeding and pressing device can press the retaining spring of the clutch booster easily and efficiently. The pressing method can ensure that the retaining spring of the clutch booster is easy to press and has high efficiency.

[0004] The above-mentioned press-fitting device presses the retaining spring by mechanical press-fitting, which can effectively reduce labor intensity and improve the quality of finished products. However, since it is impossible to achieve complete consistency during the processing of the sleeve, the sleeves are long and short. In order to ensure the accurate positioning of the sleeve, the position of the sleeve is generally adjusted by retaining springs of different thicknesses. The sleeve needs to be adapted to a variety of retaining springs for press-fitting. When the above-mentioned press-fitting device presses retaining springs of different specifications, it is necessary to replace the retaining springs pre-stored in the feeding mechanism. The replacement process is time-consuming and labor-intensive, resulting in low production efficiency. Therefore, it is necessary to design an optional press-fitting device for automobile clutch retaining springs to solve the above-mentioned problems. Summary of the invention

DETAILED DESCRIPTION

[0023] The optional press-fitting device for the automobile clutch retaining spring is composed of a frame 1, a silo 2, a press-fitting mechanism 3 and a detection mechanism 4. The frame 1 is provided with a silo 2 to store retaining springs of various specifications, so as to facilitate selection and use during press-fitting. The frame 1 at the front end of the silo 2 is provided with a press-fitting mechanism 3 to press-fit the retaining spring onto a workpiece through the press-fitting mechanism 3. The frame 1 at one side of the discharging direction of the press-fitting mechanism 3 is provided with a detection mechanism 4 to detect the workpiece after the retaining spring is press-fitted through the detection mechanism 4, so as to ensure the press-fitting quality of the retaining spring, and further ensure the quality of the finished product.

[0024] The material bin 2 is composed of a material rack 201, a material rod 202, a material pushing cylinder 203, a material selection slide rail 204, a material receiving plate 205 and a push plate 206. A plurality of material rods 202 for storing retaining rings are arranged on the material rack 201. The bottom end of the material rod 202 is arranged at an interval from the material rack 201. The retaining rings stored in the material rod 202 can fall on the material rack 201 under the action of their own gravity, and the retaining rings can be discharged by pushing the retaining rings on the material rack 201. Since a plurality of material rods 202 are arranged, retaining rings of different specifications can be stored through the material rods 202, so that retaining rings of different specifications can be taken out. Compared with replacing retaining rings, it can effectively improve efficiency and reduce labor intensity. A material pusher cylinder 203 is provided on the material rack 201 at the rear end of the material rod 202, and a push plate 206 is provided on the material pusher cylinder 203. The function of the material pusher cylinder 203 is to push the push plate 206 to move through the material pusher cylinder 203, and then the moving push plate 206 pushes out the retaining spring to discharge the retaining spring. A material selection slide rail 204 is provided on the material rack 201 at the front end of the material rod 202, and a material receiving plate 205 is installed on the material selection slide rail 204 through a slide seat. The material receiving plate 205 can move on the material selection slide rail 204 through a slide seat, and then the material receiving plate 205 can move to the front end of the selected retaining spring to receive the pushed retaining spring, so as to transfer the selected retaining spring to the press-fitting mechanism. Rodless cylinders 207 are respectively provided on the material racks 201 at both ends of the material selection slide rail 204, and push plates 206 are provided on the rodless cylinders 207. The function of the rodless cylinder 207 is to push the push plate 206 on the rodless cylinder 207 to move, and then the moving push plate 206 pushes the retaining spring on the receiving plate 205 to move, so that the retaining spring is discharged from the receiving plate 205.

[0025] A lifting cylinder 208 is installed at one end of the material selection slide 204 through a support, and a re-inspection displacement sensor 209 is provided at the piston rod end of the lifting cylinder 208. The lifting cylinder 208 drives the re-inspection displacement sensor 209 to move up and down through the lifting cylinder 208, thereby driving the re-inspection displacement sensor 209 to squeeze the retaining spring on the material receiving plate 205, and the re-inspection displacement sensor 209 detects the thickness of the retaining spring on the material receiving plate 205 by the displacement of the piston rod end of the lifting cylinder 208, thereby re-inspecting the retaining spring to ensure that the retaining spring entering the press-fitting mechanism matches the shaft sleeve, thereby ensuring the quality of the finished product. A defective material tray 210 is installed at the other end of the material selection slide 204 through a support, so that the retaining spring that fails the re-inspection can be loaded through the defective material tray 210.

[0026] The press-fitting mechanism is composed of a support frame 301, a press-fitting electric cylinder 302 and a pressing head 303. The support frame 301 is provided with a press-fitting electric cylinder 302, and the piston rod end of the press-fitting electric cylinder 302 is provided with a pressing head 303. The function of the press-fitting electric cylinder 302 is to drive the pressing head 303 to move up and down through the press-fitting electric cylinder 302, and then the pressing head 303 moving downward presses the retaining spring, so that the retaining spring is pressed on the central axis of the workpiece.

[0027] A pressing lifting plate 304 is movably mounted on the support frame 301 below the pressing head 303, a connecting plate 305 is provided on the pressing lifting plate 304, and guide grooves 306 are provided on the connecting plate 305 and the receiving plate 205, respectively. The function of the connecting plate 305 is to transfer the clamping spring transferred from the receiving plate 205 to the pressing mechanism through the connecting plate 305, and guide the clamping spring to move below the pressing head 303. The function of the guide groove 306 is to limit the position of the clamping spring through the guide groove 306, prevent the clamping spring from shifting during the transfer process, ensure the accurate position of the clamping spring after transfer, and further ensure accurate press-fitting.

[0028] A plurality of pull-down cylinders 309 are arranged in parallel below the clamping lifting plate 304, and the piston rod ends of the pull-down cylinders 309 are fixedly connected to the clamping lifting plate 304. A connecting sleeve 307 is arranged at the bottom of the clamping lifting plate 304 at the front end of the connecting plate 305. The function of the pull-down cylinder 309 is to pull the clamping lifting plate 304 to be lifted and lowered by the pull-down cylinder 309, and then drive the connecting sleeve 307 to be lifted and lowered during the lifting and lowering process of the clamping lifting plate 304, so that the connecting sleeve 307 is sleeved on the workpiece shaft sleeve. On the one hand, the workpiece is positioned by the connecting sleeve 307 to ensure the accuracy of the workpiece position and the quality of the press-fitting; on the other hand, the connecting sleeve 307 moving downward can squeeze the shaft sleeve downward, so that the shaft sleeve overcomes the spring elastic force, thereby exposing the clamping position of the retaining spring, which is convenient for the installation of the retaining spring. A transition sleeve 308 is arranged in the connecting sleeve 307, and the top end of the transition sleeve 308 is conical. Since the top of the transition sleeve 308 is in the shape of a cone that is narrow at the top and wide at the bottom, the retaining spring can be easily inserted into the top of the transition sleeve 308, thereby positioning the retaining spring; at the same time, since the top of the transition sleeve 308 is narrow at the top and wide at the bottom, when the pressure head 303 pushes the retaining spring to move downward, the retaining spring can be gradually expanded under the action of the transition sleeve 308, thereby facilitating the retaining spring to be installed on the center axis of the workpiece.

[0029] A pre-pressing cylinder 310 is arranged on the support frame 301 on one side of the press-fitting electric cylinder 302, and a pre-pressing head 311 is arranged at the end of the piston rod of the pre-pressing cylinder 310. The function of the pre-pressing cylinder 310 is to drive the pre-pressing head 311 to rise and fall through the pre-pressing cylinder 310, so as to press down the workpiece sleeve through the downwardly moving pre-pressing head 311, so as to avoid that the gap between the sleeve and the center shaft is too small, the sleeve and the center shaft are too tight, and the pull-down cylinder 309 cannot press down the sleeve.

[0030] The detection mechanism is composed of a detection bracket 401, a lateral adjustment cylinder 402, a longitudinal adjustment cylinder 403, a clamping cylinder 404, a clamping jaw 405 and a diameter detection displacement sensor 406. The detection bracket 401 is provided with a lateral adjustment cylinder 402, the lateral adjustment cylinder 402 is provided with a longitudinal adjustment cylinder 403, the longitudinal adjustment cylinder 403 is provided with a clamping cylinder 404, the clamping cylinder 404 is provided with a clamping jaw 405, and one side of the clamping jaw 405 is provided with a diameter detection displacement sensor 406 for detecting the displacement of the clamping jaw. The function of the clamping cylinder 404 is to drive the clamping jaw 405 through the clamping cylinder 404 so that the clamping jaw 405 can be clamped on both sides of the installed retaining ring. The function of the diameter detection displacement sensor 406 is to detect the displacement of the clamping jaw 405 during the movement process through the diameter detection displacement sensor 406, and to detect the diameter of the retaining ring through the displacement of the clamping jaw 405 in the process of the clamping jaw 405 clamping the retaining ring, thereby detecting whether the retaining ring is pressed into place. The function of the lateral adjustment cylinder 402 is to drive the longitudinal adjustment cylinder 403 to move horizontally through the lateral adjustment cylinder 402, and then drive the clamping jaw 405 to move horizontally through the clamping cylinder 404 during the movement of the longitudinal adjustment cylinder 403, thereby adjusting the horizontal position of the clamping jaw 405. The function of the longitudinal adjustment cylinder 403 is to drive the clamping cylinder 404 to move longitudinally through the longitudinal adjustment cylinder 403, and then drive the clamping jaw 405 to move longitudinally, thereby adjusting the longitudinal position of the clamping jaw 405. The position of the clamping jaw 405 is adjusted by the lateral adjustment cylinder 402 and the longitudinal adjustment cylinder 403, ensuring that the clamping jaw 405 can accurately clamp the retaining spring, and ensuring accurate detection of the retaining spring itself.

[0031] When the optional press-fitting device of the automobile clutch retaining spring is working, the workpiece is transferred to the bottom of the press-fitting mechanism 3. After the workpiece is in place, according to the specifications of the retaining spring selected for the sleeve, the receiving plate 205 of the material bin 2 is moved so that the receiving plate 205 moves to the front end of the corresponding material rod 202. After the receiving plate 205 is in place, the pushing cylinder 203 is started to push the corresponding retaining spring onto the receiving plate 205. After the retaining spring is in place, the receiving plate 205 is reset and moves to the bottom of the re-inspection displacement sensor 209. After the receiving plate 205 is reset, the lifting cylinder 208 drives the re-inspection displacement sensor 209 downward to squeeze the retaining spring on the receiving plate 205, and the thickness of the retaining spring is detected by the re-inspection displacement sensor 209. After the detection is completed, the re-inspection displacement sensor 209 is reset upward. When the thickness of the circlip is unqualified, the receiving plate 205 drives the circlip to move to the side of the defective receiving tray 210, and the rodless cylinder 207 pushes the circlip on the receiving plate 205 through the push plate 206, and pushes the circlip from the receiving plate 205 into the defective receiving tray 210. After the circlip is pushed out from the receiving plate 205, the above process is repeated to feed the circlip to the receiving plate 205 again, and the above process is repeated until the thickness of the circlip is qualified. When the thickness of the circlip is qualified, the receiving plate 205 is docked with the connecting plate 305. After the docking is completed, the rodless cylinder 207 pushes the circlip on the receiving plate 205 through the push plate 206, and pushes the circlip from the receiving plate 205 and the connecting plate 305 to the top end of the transition sleeve 308 in sequence. After the retaining ring is set on the top end of the transition sleeve 308, the pull-down cylinder 309 presses down the workpiece sleeve by pressing the lifting plate 304 and the connecting sleeve 307 in turn to overcome the spring force of the workpiece, and at the same time positions the workpiece through the connecting sleeve 307. After the workpiece sleeve is in place, the press-fitting electric cylinder 302 presses down the retaining ring through the pressure head 303 to press the retaining ring into place. After the retaining ring is pressed into place, the connecting sleeve 307 and the pressure head 303 are reset respectively, and the workpiece moves to the detection mechanism 4. After the workpiece moves into place, the lateral adjustment cylinder 402 and the longitudinal adjustment cylinder 403 adjust the position of the clamping jaws 405 so that the clamping jaws 405 move to both sides of the retaining spring. After the clamping jaws 405 are adjusted into place, the clamping cylinder 404 drives the clamping jaws 405 to clamp on both sides of the retaining spring. In the process of the clamping jaws 405 clamping the retaining spring, the diameter detection displacement sensor 406 detects the diameter of the retaining spring to determine whether the press-fitting is qualified.

[0032] The optional press-fitting device for the automobile clutch retaining spring can pre-store retaining springs of various specifications through the silo to meet the assembly requirements of different shaft sleeves. When press-fitting retaining springs, only the corresponding retaining springs need to be selected for assembly without replacing the retaining springs, thereby greatly improving production efficiency and reducing labor intensity. The retaining springs can be re-inspected by the re-inspection displacement sensor to ensure that the installed retaining springs are qualified and the quality of the finished product is guaranteed. The finished product can be inspected by the detection mechanism to ensure that the retaining springs are pressed in place. The problem of low production efficiency and high labor intensity caused by the need to replace retaining springs when installing retaining springs of different specifications in the existing press-fitting device is solved.
