Description

Technical Field

[0001] This utility model relates to a mobile pin pressing machine device, belonging to the technical field of mechanical processing equipment. Background Technology

[0002] In the automotive parts manufacturing industry, camshafts are key components, and locating pins are typically installed on their end faces. The assembly process of these locating pins significantly impacts product accuracy and production efficiency. Currently, due to the weight of camshafts (approximately 50 kg), traditional pin-pressing machines typically involve lifting the workpiece individually and placing it onto a dedicated press. This cumbersome operation requires lifting and lowering the camshaft, while the pressing process itself takes only 3 seconds. The handling time far exceeds the assembly time, posing risks of product damage and operator safety, resulting in low production efficiency and impacting product quality stability. Furthermore, traditional pin-pressing machines are usually designed for specific workpiece models. When different locating pin specifications need to be installed, the entire machine must be replaced or complex adjustments must be made, failing to quickly adapt to diverse production needs and lacking flexibility. Moreover, the fixed height and position of the pin-pressing machine require operators to frequently adjust the workpiece's posture to match the equipment. Especially in multi-station production scenarios, repetitive positioning operations increase the manpower burden, leading to low efficiency, high cost, and poor safety in the camshaft locating pin assembly process. Summary of the Invention

[0003] To address the problems existing in the prior art, this invention provides a mobile pressing pin machine device. This invention can improve the accuracy and efficiency of pressing and installing positioning pins on camshaft workpieces, and can also reduce the risk of workpiece collisions and personnel safety hazards.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows: a mobile pin-pressing machine device, comprising a product placement unit, a cylindrical pin positioning and guiding unit, and a mobile pin-pressing machine unit; the product placement unit includes a mobile trolley for placing camshaft products, the mobile trolley having two rows of symmetrical pulley groups, with one camshaft product placed between every two pulley groups; the cylindrical pin positioning and guiding unit includes a cylindrical pin positioning guide sleeve, a locking screw, and a cylindrical positioning pin; the locking screw is installed on the cylindrical pin positioning guide sleeve for fixing the cylindrical pin positioning guide sleeve; the cylindrical positioning pin matches the cylindrical pin positioning guide sleeve for positioning the cylindrical positioning pin and the camshaft product at the assembly position; the mobile pin-pressing machine unit includes a product positioning seat, a pin-pressing head, a front seat of a pneumatic-hydraulic booster cylinder, a pneumatic-hydraulic booster cylinder, a rear seat of a pneumatic-hydraulic booster cylinder, a cylindrical guide rail, a flange-type linear ball bearing, and a pneumatic-hydraulic booster cylinder. The system comprises a cylinder base plate, a circular flange seat, a lifting mechanism base plate frame, directional wheels, universal wheels, a cylinder, a bevel gear lift, a handwheel, a handle, a pneumatic component base plate, an air source dual unit, a solenoid valve, and a controller. The lifting mechanism base plate frame has directional wheels and universal wheels installed below it, and a cylinder and a bevel gear lift connected to the handwheel installed above it. The circular flange seat, cylindrical guide rail, and flange-type linear ball bearing support the pneumatic-hydraulic booster cylinder base plate. A pneumatic-hydraulic booster cylinder, a front seat, and a rear seat are installed above the base plate. An iron plate is fixedly installed on the side of the base plate, and a pneumatic component base plate is installed above the iron plate. An air source dual unit, a solenoid valve, and a controller are installed on the pneumatic component base plate. The controller is electrically connected to the solenoid valve, and the solenoid valve is connected to the air source dual unit and the pneumatic-hydraulic booster cylinder. The product positioning seat is installed in front of the pneumatic-hydraulic booster cylinder, and a pressure pin is installed on the pneumatic-hydraulic booster cylinder.

[0005] Furthermore, the mobile trolley is detachably connected to the base plate of the lifting mechanism, making it easy to handle independently or use in combination.

[0006] Furthermore, the pressure pin head is connected to the output end of the gas-liquid booster cylinder via a threaded connection or a quick-release structure, allowing for the replacement of pressure pin heads of different specifications to adapt to different models of product positioning pins.

[0007] Furthermore, the product positioning seat is provided with a positioning surface that matches the shape of the camshaft product, and the positioning surface is perpendicular to the central axis of the pressure pin head to ensure the assembly accuracy of the product positioning pin.

[0008] Furthermore, the number of both the omnidirectional wheels and the directional wheels is no less than two, and the omnidirectional wheels are equipped with a braking mechanism to facilitate device positioning.

[0009] Moreover, the handwheel is fixedly connected to the input shaft of the bevel gear lift. By rotating the handwheel, the screw of the bevel gear lift is driven to rise and fall, thereby causing the bottom plate of the gas-liquid booster cylinder to move up and down along the cylindrical guide rail.

[0010] Furthermore, a handle is installed on the side of the bottom plate of the gas-liquid booster cylinder opposite to the side of the fixed mounting iron plate, which facilitates the movement of the device.

[0011] As can be seen from the above technical solution, the mobile pressing pin machine device provided by this utility model has the following advantages over the prior art:

[0012] (1) In the technical solution adopted by this utility model, no less than two universal wheels and directional wheels are provided under the bottom plate frame of the lifting mechanism. With the side handle, the device can move freely and be accurately positioned in the workshop. The universal wheel brake mechanism can fix the device instantly after reaching the target work position, avoiding shaking during the pressing process. This solves the problem of time-consuming positioning and additional fixing required by traditional equipment, improving production efficiency while ensuring pressing stability.

[0013] (2) In the technical solution adopted by this utility model, the cylindrical pin positioning guide unit pre-calibrates the assembly hole position of the product positioning pin and the camshaft workpiece through the precise cooperation of the cylindrical pin positioning guide sleeve and the cylindrical positioning pin. The positioning surface of the product positioning seat is completely matched with the shape of the camshaft, and the positioning surface is perpendicular to the central axis of the pressing pin head, ensuring that the pressing direction is strictly perpendicular to the workpiece reference surface, avoiding the accuracy deviation caused by tilted assembly. At the same time, the gas-liquid booster cylinder is used to provide pressing power, the pressure output is more uniform and the impact is smaller, which significantly improves the pressing accuracy and efficiency of the product positioning pin.

[0014] (3) In the technical solution adopted by this utility model, the pressure pin head and the output end of the pneumatic-hydraulic booster cylinder are connected by threads or quick-release structure, which can complete the replacement of pressure pin heads of different specifications without tools. It is suitable for the pressing needs of various models of camshaft products and product positioning pins, and has good versatility. In addition, the mobile trolley and the lifting mechanism base plate are detachably connected. It can be used as an independent workpiece carrier for the transportation and storage of camshafts, or it can be combined with the pressure pin machine unit to form an integrated workstation, realizing seamless connection between operation and pressing, reducing the collision damage caused by secondary handling of workpieces, and improving the continuity of the production process.

[0015] (4) The device in the technical solution adopted by this utility model adopts a modular design. The product placement unit, the cylindrical pin positioning and guiding unit, and the mobile pressing pin unit are assembled independently. In case of failure, they can be quickly disassembled and replaced without the need for overall shutdown and maintenance. Moreover, the cylindrical guide rail is matched with the flange-type linear ball bearing, resulting in low motion resistance, effectively reducing the accuracy decay caused by mechanical wear, improving the reliability and stability of the equipment in long-term operation, and significantly reducing maintenance costs and difficulties.
