Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic cylinder production equipment, specifically to an automatic feeding and positioning clamping mechanism for hydraulic cylinder piston rods. Background Technology

[0002] As the core transmission component of the hydraulic system, the piston rod of the hydraulic cylinder directly determines the operational stability and service life of the hydraulic cylinder through its machining accuracy. In the production process of the piston rod, automatic feeding and positioning clamping are key steps before subsequent machining processes such as turning, grinding, and electroplating. The clamping mechanism is required to quickly and accurately fix the piston rod to prevent it from rotating or undergoing axial or radial displacement during machining, so as to ensure the consistency of machining dimensions.

[0003] In the process of developing this application, the following problems were found with this technology: Existing hydraulic cylinder piston rod feeding and positioning clamping mechanisms have many technical defects in practical applications. Existing clamping mechanisms mostly adopt flat clamping plates or single-end chuck-type fixing structures. These structures can only limit the local plane or end of the piston rod and cannot form a full-circumferential fitting positioning effect with the cylindrical outer wall of the piston rod. When the piston rod is in the feeding or processing state, it is easily affected by mechanical vibration, processing cutting force and other factors, which can easily cause circumferential rotation or axial slippage, resulting in the outer circle accuracy of subsequent turning and the coaxiality of thread processing exceeding the standard. The finished product qualification rate can only reach about 85%, which seriously restricts production efficiency.

[0004] Therefore, an automatic feeding and positioning clamping mechanism for hydraulic cylinder piston rod is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic feeding and positioning clamping mechanism for hydraulic cylinder piston rods to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: An automatic feeding and positioning clamping mechanism for hydraulic cylinder piston rods includes two sets of support platforms. A conveying device is installed on the upper end of the two sets of support platforms. The conveying device includes a conveyor belt. A clamping assembly for positioning and clamping the piston rod is installed on the outer end of the front set of support platforms. The clamping assembly is located on the conveying path of the conveying device. A limit component is provided on the outer end of the clamping assembly. A feeding component is installed inside the clamping assembly. A control component is provided on the top of the inner wall of the clamping assembly.

[0007] Furthermore, the clamping assembly includes a base plate, which is installed on the inner wall of the front set of support platforms. An electric telescopic rod is installed on the upper surface of the base plate, and a connecting frame is installed at the output end of the electric telescopic rod. V-shaped clamps are installed on the bottom of the inner walls on both sides of the connecting frame. Two sets of support columns are installed at the upper end of the conveying device, and a top plate is installed between adjacent sides of the two sets of support columns. An arc-shaped limiting plate is installed on the lower surface of the top plate. The left and right sides of the arc-shaped limiting plate are located directly above the two sets of V-shaped clamps, and the two sets of V-shaped clamps are located on the conveying path of the conveying device.

[0008] Furthermore, a rubber pad is adhered to the inner wall of the arc-shaped limiting plate.

[0009] Furthermore, the control component includes a control panel and a pressure sensing strip. The control panel is installed on one side of the front set of the support platforms. A groove is formed inside the rubber pad. The pressure sensing strip is installed inside the groove of the rubber pad. The output end of the pressure sensing strip is electrically connected to the input end of the control panel. The output end of the control panel is wiredly connected to the input end of the electric telescopic rod.

[0010] Furthermore, the feeding assembly includes two sets of fixing frames, which are respectively installed on the lower surfaces of the two sets of V-shaped clamps. Electric telescopic rods are installed on the bottom inner walls of both sets of fixing frames. Sliding grooves are opened on the bottom inner walls of both sets of V-shaped clamps. Inclined plates are slidably connected inside the sliding grooves of both sets of V-shaped clamps. The output ends of the electric telescopic rods are respectively installed through the two sets of V-shaped clamps on the lower surfaces of the two sets of inclined plates.

[0011] Furthermore, the limiting component includes two sets of sliders, which are respectively installed on opposite sides of the two sets of V-shaped clamps. The upper surfaces of the two sets of sliders are provided with through holes, and the interiors of the through holes of the two sets of sliders are slidably connected with limiting rods. The bottom ends of the two sets of limiting rods are installed on the upper surface of the base plate.

[0012] Furthermore, multiple sets of flexible limiting rods are bonded to the outer end of the conveyor belt of the conveying device.

[0013] The beneficial effects of this utility model are as follows: 1. This utility model uses an electric telescopic rod to push the connecting frame, causing two sets of V-shaped clamps to move upwards. This allows the V-grooves of the V-shaped clamps to fit against the outer wall of the piston rod. When the two sets of V-shaped clamps push the piston rod upwards, the outer end of the piston rod abuts against the inner wall of the arc-shaped limiting plate. This causes the inner wall of the arc-shaped limiting plate to contact the upper half of the piston rod, thus preventing the piston rod from rotating or moving during subsequent assembly or processing. This ensures the accuracy of subsequent piston rod processing and improves the practicality of the device.

[0014] 2. This utility model uses an electric telescopic rod to push an inclined plate upward along a T-shaped groove until the upper end of the inclined plate extends out of the V-shaped groove. At this point, the inclined plate is tilted at 30°, causing the piston rod to slide down the inclined surface of the plate into the receiving frame below. Then, the operator activates the electric telescopic rod to reset the inclined plate to the bottom of the groove, waiting for the next material feeding. This eliminates the need for manual unloading of the piston rod when processing or assembling, increasing efficiency by more than 60% compared to traditional manual material handling. It also avoids the risk of burns or collisions during manual material handling, thus improving workshop safety. Attached Figure Description

[0021] like Figures 1 to 4 As shown, an automatic feeding and positioning clamping mechanism for hydraulic cylinder piston rods includes two sets of support platforms 1. A conveying device 2 is installed on the upper end of each support platform 1. The conveying device 2 includes a conveyor belt. A clamping assembly 4 for positioning and clamping the piston rod is installed on the outer end of the front support platform 1. The clamping assembly 4 is located on the conveying path of the conveying device 2. A limit component 6 is provided on the outer end of the clamping assembly 4. A feeding component 5 is installed inside the clamping assembly 4. A control component 7 is provided on the top of the inner wall of the clamping assembly 4. Specifically, by activating the conveying device 2, the piston rod is transferred to the inside of the clamping assembly 4. At this time, the operator activates the clamping assembly 4 to clamp the piston rod inside the clamping assembly 4, allowing the piston rod to be processed or assembled synchronously during transfer. This prevents the piston rod from rotating or moving during subsequent assembly or processing, thus ensuring the accuracy of subsequent piston rod processing and shortening the time spent on processing or assembling the piston rod, thereby improving the practicality of the device.

[0022] The clamping assembly 4 includes a base plate 401, which is installed on the inner wall of a front set of support platforms 1. An electric telescopic rod 402 is mounted on the upper surface of the base plate 401. A connecting frame 403 is mounted on the output end of the electric telescopic rod 402. V-shaped clamping plates 404 are installed on the bottom of the inner walls on both sides of the connecting frame 403. Two sets of support columns 405 are installed at the upper end of the conveying device 2. A top plate 406 is installed between adjacent sides of the two sets of support columns 405. An arc-shaped limiting plate 407 is installed on the lower surface of the top plate 406. The left and right sides of the arc-shaped limiting plate 407 are located directly above the two sets of V-shaped clamping plates 404. The positions of the two sets of V-shaped clamping plates 404 are located within the conveying device... On the transmission path of 2; specifically, when the piston rod is transmitted between the two sets of V-shaped clamps 404, the electric telescopic rod 402 is activated to push the connecting frame 403 to move the two sets of V-shaped clamps 404 upward, so that the V-groove of the V-shaped clamps 404 fits against the outer wall of the piston rod. At this time, when the two sets of V-shaped clamps 404 push the piston rod upward, the outer end of the piston rod abuts against the inner wall of the arc-shaped limiting plate 407, thereby making the inner wall of the arc-shaped limiting plate 407 contact the upper half of the piston rod, thus preventing the piston rod from rotating or moving during subsequent assembly or processing, thereby ensuring the accuracy of subsequent piston rod processing, and thus improving the practicality of the device.

[0023] A rubber pad 8 is bonded to the inner wall of the arc-shaped limiting plate 407. Specifically, the rubber pad 8 is made of rubber, and its elastic properties can buffer the contact force between the arc-shaped limiting plate 407 and the piston rod, preventing indentations on the piston rod surface. The anti-slip texture on the inner wall of the rubber pad 8 can increase the friction between the piston rod and the contact surface of the arc-shaped limiting plate 407, preventing the piston rod from slipping even under processing vibration, thereby further improving the positioning stability after clamping and thus improving the practicality of the device.

[0024] The control component 7 includes a control panel 701 and a pressure sensing strip 702. The control panel 701 is installed on one side of a front support platform 1. A groove is provided inside the rubber pad 8. The pressure sensing strip 702 is installed inside the groove of the rubber pad 8. The output end of the pressure sensing strip 702 is electrically connected to the input end of the control panel 701. The output end of the control panel 701 is wired to the input end of the electric telescopic rod 402. Specifically, when the piston rod moves with the V-shaped clamp 404 to contact the arc-shaped limit plate 407, the rubber pad 8 is deformed by pressure. At this time, the pressure sensing strip 702 detects the pressure signal, converts the analog signal into a digital signal and transmits it to the control panel 701. After comparing with the set value, the control panel 701 will trigger an audible and visual alarm and control the electric telescopic rod 402 to stop its operation, thereby avoiding damage to the clamping component 4 or the piston rod.

[0025] The feeding assembly 5 includes two sets of fixing brackets 501, which are respectively installed on the lower surfaces of two sets of V-shaped clamps 404. Electric telescopic rods 502 are installed on the bottom inner walls of both sets of fixing brackets 501. Slide grooves are formed on the bottom inner walls of both sets of V-shaped clamps 404, and inclined plates 503 are slidably connected inside the slide grooves of both sets of V-shaped clamps 404. The output ends of the electric telescopic rods 502 pass through the two sets of V-shaped clamps 404 and are installed on the lower surfaces of the two sets of inclined plates 503. Specifically, the inclined plates are pushed by activating the electric telescopic rods 502. 503 slides upward along the T-shaped groove until the upper end of the inclined plate 503 extends out of the V-shaped groove. At this time, the inclined plate 503 is tilted at 30°, causing the piston rod to slide down the inclined surface of the inclined plate 503 into the receiving frame below. Then, the worker activates the electric telescopic rod 502 to reset, driving the inclined plate 503 back to the bottom of the groove, waiting for the next material unloading. This eliminates the need for manual unloading when the piston rod is processed or assembled, improving efficiency by more than 60% compared to traditional manual material handling. It also avoids the risk of burns or collisions during manual material handling, thus improving workshop safety.

[0026] The limiting component 6 includes two sets of sliders 602, which are respectively installed on opposite sides of the two sets of V-shaped clamps 404. The upper surface of each set of sliders 602 is provided with a through hole, and the inside of the through hole of each set of sliders 602 is slidably connected to a limiting rod 601. The bottom ends of the two sets of limiting rods 601 are installed on the upper surface of the base plate 401. Specifically, when the electric telescopic rod 402 drives the V-shaped clamp 404 to move, the sliders 602 on the outside of the V-shaped clamp 404 slide synchronously along the limiting rods 601, so that the guiding effect of the limiting rods 601 can limit the movement trajectory of the V-shaped clamp 404, thereby preventing the V-shaped clamp 404 from shifting left and right or tilting up and down due to uneven force, thus improving the stability of the clamping component 4 during use.

[0027] Multiple sets of flexible limiting rods 3 are bonded to the outer end of the conveyor belt of the conveying device 2. Specifically, by bonding multiple sets of flexible limiting rods 3 to the outer end of the conveying device 2, the positions of multiple sets of piston rods are separated when the conveying device 2 conveys the piston rods, so as to prevent multiple sets of piston rods from rolling to the upper end of the two sets of V-shaped clamps 404 at the same time when the conveying device 2 is feeding materials.

[0028] In summary: By activating the electric telescopic rod 402, the connecting frame 403 is pushed to move the two sets of V-shaped clamps 404 upward, so that the V-shaped grooves of the V-shaped clamps 404 fit against the outer wall of the piston rod. At this time, when the two sets of V-shaped clamps 404 push the piston rod upward, the outer end of the piston rod abuts against the inner wall of the arc-shaped limiting plate 407, thereby making the inner wall of the arc-shaped limiting plate 407 contact the upper half of the piston rod, thus preventing the piston rod from rotating or moving during subsequent assembly or processing, thereby ensuring the accuracy of subsequent piston rod processing. Simultaneously, by activating the electric telescopic rod 502, the inclined plate 503 is pushed upward along the T-shaped groove until the upper end of the inclined plate 503 extends out of the V-shaped groove. At this time, the inclined plate 503 is tilted at 30°, causing the piston rod to slide down the inclined surface of the inclined plate 503 into the receiving frame below. Then, the worker activates the electric telescopic rod 502 to reset the inclined plate 503 to the bottom of the groove, waiting for the next material unloading. This eliminates the need for manual unloading when the piston rod is processed or assembled, improving efficiency by more than 60% compared to traditional manual material handling. It also avoids the risk of burns or collisions during manual material handling, thus improving workshop safety.
