Description

Technical Field

[0001] This utility model relates to the field of disassembly and assembly tools, specifically to a multi-functional columnar product assembly gun. Background Technology

[0002] In modern industry, speed reducers and various column products often use interference fit assembly to ensure working stability. However, the existing assembly relies on the traditional hammering assembly method. This process forces the column into the mounting hole by external force, which has defects such as uneven distribution of impact load, stress concentration, loss of assembly accuracy (poor coaxiality), accelerated wear due to off-center load, and the initiation and propagation of cracks in parts. In addition, the assembly efficiency is low and it depends on manual experience, which seriously restricts the reliability and service life of products.

[0003] Traditional hammering assembly methods cannot meet the assembly requirements of "high precision, low damage, and high efficiency" for reducers and column products, resulting in low assembly pass rate, frequent early product failures, and high maintenance costs. At the same time, the assembly efficiency is difficult to match with large-scale production, and the assembly quality is greatly affected by human skills and has poor stability. Summary of the Invention

[0004] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore, the purpose of this utility model is to provide a multifunctional cylindrical product assembly gun to improve the applicability of the device.

[0005] The objective of this utility model can be achieved through the following technical solutions: A multi-functional cylindrical product assembly gun includes a gun body and a connecting plate detachably connected to the output end of the gun body. Multiple slide rails are connected to the connecting plate, wherein at least two hydraulic push clamps and at least two hydraulic grippers are slidably fitted on each slide rail, and one hydraulic push clamp and one hydraulic gripper form a gripper assembly. The two gripper assemblies are located at opposite ends of the slide rail.

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model. Example

[0020] This embodiment mainly describes the basic mechanical structure of the multi-functional column product assembly gun, the hydraulic power core, and the control and display system for achieving precise operation, which constitutes the basis for the equipment to realize basic gripping and pushing functions.

[0021] like Figure 1 , Figure 2 As shown, a multi-functional cylindrical product assembly gun includes a gun body 1 and a detachable connecting plate 2 connected to its output end. This modular design allows the gun body 1, as the operation and power core, to be quickly replaced with connecting plates 2 pre-set with different specifications of grippers, thereby flexibly handling cylindrical products of different diameters or assembly forms and improving the equipment's versatility.

[0022] Multiple slide rails 21 are connected to the connecting plate 2, and each slide rail 21 is slidably fitted with a gripper assembly. Each assembly consists of a hydraulic pusher 22 and a hydraulic gripper 23. The hydraulic control button 13 on the gun body 1 can be electrically connected to the hydraulic pusher 22 and the hydraulic gripper 23 respectively to achieve hydraulic drive. Its working principle is as follows: pressing the hydraulic control button 13 pressurizes hydraulic oil in the miniature hydraulic pump inside the gun body 1, driving the built-in hydraulic rod of the hydraulic gripper 23 to extend and clamp the column, or driving the telescopic hydraulic rod of the hydraulic pusher 22 to extend and apply thrust. This hydraulic drive method provides uniform, stable, and impact-free thrust, effectively avoiding damage to parts or assembly tilting caused by traditional hammering methods, significantly improving assembly efficiency and quality consistency.

[0023] Specifically, the hydraulic gripper 23 includes an external telescopic rod and an internal hydraulic rod, while the hydraulic pusher 22 includes a pusher rod and an internal telescopic hydraulic rod. An arc-shaped pusher head 24 is fixedly connected to the end of the pusher rod furthest from the slide rail 21, its inner arc surface covered with an anti-slip rubber pad. This design increases the contact area with the end face of the column, disperses the thrust, and, together with the anti-slip rubber pad, effectively prevents scratches or indentations on the end face of the column during the pushing process, thus protecting the product.

[0024] To achieve precise control, a display screen 11 is installed on the outer wall of the gun body 1. This display screen 11 is a distance monitoring display screen, which displays the advancing distance of the hydraulic push clamp 22 in real time through a built-in high-precision displacement sensor (such as a grating ruler). Its display accuracy is no less than four decimal places, transforming the ambiguous assembly process into a data-driven and visualized precision operation, ensuring that the depth of each assembly strictly meets the process requirements, which is crucial for the assembly of precision instruments, bearings, etc.

[0025] In terms of human-computer interaction and equipment maintenance, the gun body 1 is equipped with a charging port 12, which is a Type-C fast charging interface, providing a universal and efficient charging solution. Simultaneously, an anti-slip cover is hinged to the charging port 12, and its inner wall is equipped with a sealing ring. This design effectively seals the charging port 12 when the dust cover is closed, preventing dust, oil, and moisture from entering the industrial environment, thus improving the durability and reliability of the equipment.

[0026] For example, an electric servo system can be used instead of a hydraulic system to achieve higher control precision and a cleaner working environment, but at a higher cost; or a pneumatic system can be used, which is less expensive, but the output force is not as smooth as that of a hydraulic system.

[0027] For example, a pressure sensor can be added to the hydraulic circuit to achieve dual closed-loop control of "pressure-displacement"; the hydraulic control button 13 can be upgraded to a stepless speed-regulating trigger; the display screen 11 can be upgraded to a touch screen with adjustable parameters, and an audible and visual prompt function for "target arrival" or a wireless data transmission module can be added.

[0028] In use, the operator holds the gun body 1 and installs the corresponding connecting plate 2 according to the product specifications. By operating the hydraulic control button 13, the hydraulic system inside the gun body 1 is activated. First, hydraulic oil drives multiple hydraulic grippers 23 arranged in a ring array to extend, stably clamping and centering the cylindrical product. Then, hydraulic oil drives the telescopic hydraulic rod inside the hydraulic push clamp 22, causing its push rod to extend smoothly. The arc-shaped push head 24 at the front end of the push rod applies force evenly to the end face of the cylindrical product, pushing it into the designated position. During this process, a high-precision displacement sensor transmits the real-time advance distance data of the hydraulic push clamp 22 to the main control chip, and displays it on the display screen 11 with an accuracy of no less than four decimal places, allowing the operator to achieve micron-level precision assembly. The entire device is powered by a built-in battery, which is charged through a Type-C charging port 12 with a dust cover. The specific operating procedure is as follows: Preparation phase: Check the device's battery level and charge it via Type-C charging port 12. Select and install the appropriate connecting plate 2 onto the gun body 1 according to the specifications of the column to be assembled.

[0029] Positioning and preset: Power on the machine, align the assembly gun with the workpiece, and make the arc-shaped push head 24 of the hydraulic push clamp 22 abut against the end face of the column. Perform "zeroing" on the display screen 11.

[0030] Clamping and Advancing: Press the hydraulic control button 13 to drive the hydraulic gripper 23 to extend and clamp the column. After confirming a secure clamping, continue operating the hydraulic control button 13 to drive the hydraulic pusher 22 to begin advancing forward.

[0031] Precise monitoring and stopping: Observe the distance value on the display screen 11 in real time, and stop the operation when the value accurately reaches the preset target depth.

[0032] Reset and End: Reverse the operation of the control button to first retract the hydraulic push clamp 22, then release the hydraulic gripper 23. Remove the assembly gun to complete the operation. Example

[0033] This embodiment focuses on illustrating the core innovative functions of the equipment designed to solve the problem of resistance in precision or interference fit assembly.

[0034] like Figure 1 , Figure 4As shown, a high-frequency pulse vibration device is provided at the end of the hydraulic gripper 23 away from the slide rail 21. This device is electrically connected to the vibration control button 14. Its working principle utilizes the "vibration drag reduction effect," applying high-frequency, low-amplitude pulse vibration to the clamped column to intermittently convert the static friction between the mating surfaces into dynamic friction, thereby significantly reducing the axial thrust required for assembly. This function makes interference fits, which originally required enormous pressure, easier, reduces the power requirements of the hydraulic system, and avoids the risk of part deformation that may result from heavy-force assembly.

[0035] The high-frequency pulse vibration device is embedded inside the hydraulic gripper 23, and its vibration output end is matched with the clamping end of the hydraulic gripper 23. This integrated design allows vibration energy to be directly and efficiently transmitted to the column, avoiding energy loss along the transmission path. Simultaneously, the vibration control button 14 adjusts the vibration frequency of the high-frequency pulse vibration device, allowing the operator to find and set the optimal drag-reducing frequency point in real time according to the material, mass, and interference fit of different workpieces to achieve the best assembly effect.

[0036] To protect the workpiece and ensure stable clamping while applying vibration, the clamping end of the hydraulic gripper 23 is wrapped with a rubber protective layer. This protective layer effectively protects the column surface from scratches during clamping and also acts as a buffer medium for vibration transmission, allowing the vibration to act more evenly on the column. Figure 3 , Figure 4 As shown, the outer surface of the rubber protective layer is provided with multiple spaced rubber suction cups 25, whose adsorption surfaces are adapted to the outer wall of the column. When clamped, the air inside the rubber suction cups 25 is expelled to form a local negative pressure, which increases the additional adsorption force and ensures that the column can still be firmly fixed under high-frequency vibration, without slipping or falling off.

[0037] For example, a heating / cooling combination method based on thermal expansion and contraction can be used, which is effective but complex and energy-intensive; or higher frequency ultrasonic vibration can be used, which may have a better drag reduction effect, but the system cost is high.

[0038] For example, sensors can be integrated to achieve adaptive adjustment of vibration frequency and amplitude, achieving "one-click" intelligent drag reduction; a micro vacuum pump can be added to the rubber suction cup 25 for active air extraction, increasing the adsorption force to the vacuum adsorption level to cope with heavier workpieces.

[0039] In this embodiment, during interference or tight fit assembly, the operator first uses the hydraulic system to drive the hydraulic gripper 23, which is covered with a rubber protective layer and rubber suction cup 25, to clamp the column. Then, pressing the vibration control button 14 activates the high-frequency pulse vibration device embedded inside the hydraulic gripper 23, generating adjustable-frequency micro-amplitude vibrations. This vibration is efficiently transmitted to the column through the clamping end, significantly reducing the static friction between it and the mating hole. Simultaneously, the hydraulic pusher 22 applies a relatively small axial thrust, allowing the column to be smoothly and precisely assembled into place with the assistance of vibration. The synergistic effect of the rubber protective layer and rubber suction cup 25 ensures that the workpiece surface remains undamaged and is firmly fixed throughout the high-frequency vibration process. Example

[0040] This embodiment focuses on the structural layout of the equipment and the auxiliary positioning components. These designs enable the assembly gun to flexibly adapt to different working scenarios and ensure the repeatability and positioning accuracy of the operation.

[0041] like Figure 3 , Figure 4 As shown, multiple slide rails 21 are arranged in a circular array along the axis of the connecting plate 2, and the included angle between two adjacent slide rails 21 is equal. The advantage of this layout is that when multiple hydraulic grippers 23 clamp towards the center simultaneously, clamping force can be applied evenly from multiple directions to achieve automatic centering, ensuring that the column is stably fixed on the central axis of the connecting plate 2, providing a high coaxiality basis for subsequent precise assembly.

[0042] Each slide rail 21 has a limit block at both ends. This limit block is an elastic rubber block, detachably connected to the slide rail 21 by bolts. Its function is firstly to limit the sliding stroke of the gripper assembly on the slide rail 21, preventing excessive travel and interference, thus providing safety protection. Secondly, because it is detachable and adjustable, the operator can flexibly adjust the starting and ending positions of the gripper assembly according to workpieces of different lengths, greatly enhancing the equipment's flexible manufacturing capabilities.

[0043] For precise adjustment, the limit blocks are equipped with scale lines. During setup, the operator can refer to the scale lines to precisely set the limit blocks on all slide rails 21 to symmetrical positions. This ensures consistency in equipment settings across different production batches or shifts, thereby guaranteeing repeatability and positioning accuracy during product assembly. Furthermore, the limit blocks are made of elastic rubber. When the gripper assembly accidentally impacts the limit blocks, their elasticity absorbs the impact energy, providing cushioning and protection against rigid impact damage to the equipment, thus extending the service life of the mechanical structure.

[0044] For example, a three-jaw linkage chuck structure similar to that of a lathe can be used to replace the slide rail system, which has high centering accuracy but is inconvenient to adjust the clamping range; or a servo motor can be used to drive the gripper to move on the slide rail 21 and set electronic soft limits, which is convenient to adjust but the system is complex and costly.

[0045] For example, the bolt fixing of the limit block can be replaced with a quick-locking handle to achieve quick adjustment by hand; digital measuring elements such as magnetic rulers can be integrated next to the slide rail 21 to upgrade the mechanical scale to a digital display for more accurate readings; and a linkage mechanism can be designed to automatically and synchronously adjust the rest when one gripper position is adjusted.

[0046] The working principle of this embodiment lies in the adaptability and precision of its mechanical structure. First, multiple slide rails 21, evenly distributed in a ring on the connecting plate 2, ensure that the multiple grippers can automatically center and stably hold the cylindrical product during operation. Second, adjustable limit blocks with scale lines at both ends of each slide rail 21 provide flexible configuration capabilities for the equipment. The operator can loosen these elastic rubber blocks with bolts, move and fix them to a specific position according to the scale lines, thereby pre-setting precise and symmetrical sliding working ranges for workpieces of different sizes. This system not only ensures operational safety and the durability of the equipment itself (elastic buffer), but more importantly, it achieves rapid adaptation to different assembly tasks and highly repeatable precise positioning.
