Description

Technical Field

[0001] This utility model relates to the field of ball-assisted positioning fixture technology, and in particular to a ball-assisted positioning fixture. Background Technology

[0002] In mechanical assembly, the installation of ball bearings is a rather tedious task. Traditional ball bearing installation methods are mostly done manually, which is inefficient and prone to problems such as inaccurate ball bearing placement and ball bearings falling off during installation. This leads to unstable assembly quality and affects the overall performance of the product and production efficiency.

[0003] Chinese Patent Publication No.: CN 209614747 U, Publication Date: November 12, 2019. This application proposes a ball bearing quantitative assembly device, which includes a machine body, a guiding component, and a quantitative component. The machine body has a positioning structure and a feeding device. The guiding component is disposed on the machine body and has a guiding channel. The first end of the guiding channel is connected to the feeding device, and the guiding channel has a metering channel. The quantitative component is movably disposed on the machine body or the guiding component and can move relative to the guiding component to open and close the inlet and outlet of the metering channel. The shortcomings of this technical solution are: complex equipment structure, complex quantitative method of ball bearing discharge, and difficulty in positioning and assembling workpieces, resulting in decreased production efficiency.

[0004] In summary, existing ball bearing assembly devices suffer from drawbacks such as complex equipment structure, complex quantitative methods for ball bearing discharge, and difficulty in positioning and assembling workpieces, leading to decreased production efficiency. Utility Model Content

[0005] This invention aims to overcome the shortcomings of existing ball bearing assembly devices, such as complex equipment structure, complex quantitative methods for ball bearing discharge, and difficulty in positioning and assembling workpieces, which leads to a decrease in production efficiency. It provides a ball bearing auxiliary positioning fixture that simplifies the device, enables rapid quantitative and positioning assembly, and improves production efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A ball bearing-assisted positioning fixture, comprising

[0008] The storage tray has an inner wall with an arc shape and a discharge port at the center. The discharge port has a guide slope at its end.

[0009] A fixing block is placed at the discharge port and is inserted into the storage tray.

[0010] The feeding structure has a storage tray that is detachably connected to a connecting seat. The fixed block is movably connected to the connecting seat. The connecting seat is connected to a support seat. The feeding structure is connected to the support seat. The feeding structure is movably connected to a lifting plate.

[0011] The storage tray stores a number of ball bearings awaiting batch feeding. The discharge port, a circular opening at the central axis of the storage tray, is used for ball bearing feeding. A guide ramp at the end of the discharge port creates an upward-opening wedge shape at the top. A fixing block is placed at the discharge port, coinciding with the central axis of the storage tray, with its outer surface close to the wall of the discharge port. The ball bearings converge towards the discharge port under the curved inner wall of the storage tray and enter the ball bearing assembly component under the guide ramp, automatically positioning the ball bearings to their corresponding positions to complete assembly. A lifting plate facilitates the movement of the ball bearing assembly component, allowing for easy assembly and loading / unloading from the fixture. Repeating this process allows for rapid, quantitative batch assembly of ball bearings. This achieves the effects of simplifying the fixture structure, enabling precise auxiliary ball bearing positioning and quantitative assembly, increasing automation, saving labor, and ultimately improving production efficiency.

[0012] Preferably, the fixing block is connected to a limiting seat, which has a limiting groove. The limiting seat is connected to the fixing block to position the ball bearing component to be assembled via the limiting groove, thereby improving assembly convenience.

[0013] Preferably, the lifting plate is connected to the limiting seat 2, the limiting seat 2 is provided with the limiting groove 2, the fixed block is provided with the feeding groove, the feeding groove is evenly distributed on the lower outer surface of the fixed block, the feeding groove is arranged opposite to the guiding slope, the lower end of the fixed block is inserted with the movable block, the upper surface of the movable block is provided with the discharge through hole, the connecting seat is connected with the rotary drive assembly, and the movable block is rotatably connected to the connecting seat through the fixed block. A feeding groove is provided on the outer surface of the fixed block. The size of the feeding groove is adapted to the ball bearings, allowing individual balls to enter the feeding groove along the guide slope. Several feeding grooves are set according to the required feeding quantity, so that each ball enters the fixed block one by one. The movable block below the fixed block blocks the falling of the incoming balls, preventing the continuous feeding of subsequent balls from becoming uncontrollable. A discharge through hole is provided on the movable block. In the initial state, the discharge through hole and the feeding groove are staggered. By moving the fixed block and the movable block synchronously downward in the connecting seat, the balls to be fed are separated from the stored balls. During separation, the movable block is gradually driven to rotate below the fixed block by the rotation drive component, thereby connecting the discharge through hole and the feeding groove, realizing the automatic positioning and falling of a fixed quantity of balls. The lifting plate is used to place the ball bearing component to be assembled through the limiting groove on the limiting seat two, so that the ball bearing component to be assembled is automatically moved to the bottom of the movable block by the feeding structure to be connected to the ball bearing. This achieves the effects of precise auxiliary ball bearing positioning and quantitative assembly, improving automation and saving labor, thereby improving assembly efficiency.

[0014] Preferably, the fixed block is rotatably connected to a rotating seat. The lower end of the fixed block has a mounting groove connected to a bearing. The rotating seat is connected to the bearing, and the upper end of the rotating seat is rotatably connected to the fixed block via the bearing. The movable block has a base plate and a fixing screw. The base plate is connected to the movable block, the fixing screw is inserted into the base plate, and the fixing screw is threaded to the lower end of the rotating seat. The mounting groove in the fixed block, through the mounting bearing, connects the bearing to the rotating seat, thereby ensuring a stable connection between the movable block and the fixed block while allowing for smooth and stable rotation on the fixed block. The movable block is connected to the rotating seat via the fixing screw on the base plate, facilitating disassembly and assembly between the movable block and the fixed block. This improves operational smoothness and facilitates assembly and maintenance.

[0015] Preferably, the rotary drive assembly includes a guide slider and a connecting piece. The outer surface of the movable block has a positioning groove. The guide slider is connected to the connecting piece, and the connecting piece is bolted to the positioning groove. The inner wall of the connecting seat has a helical groove, and the guide slider is slidably connected to the helical groove. The guide slider in the rotary drive assembly is mounted on the positioning groove of the movable block via the connecting piece. The helical groove is a spiral-shaped curve recess on the inner wall of the connecting seat, causing the guide slider to rotate as it descends on the helical groove. This ensures that the discharge through-hole rotates to align with the feed groove for ball discharge. Simultaneously, the length of the bolt groove corresponds to the distance traveled by the discharge through-hole to align with the feed groove, preventing misalignment from affecting ball feeding. This achieves the effect of rapid and precise ball feeding through a simple structure.

[0016] Preferably, the connecting seat includes a pressure plate, a return spring, and a guide rod. The pressure plate is sleeved with the movable block. The upper surface of the connecting seat has a movable groove that communicates with the spiral groove. One end of the return spring is connected to the bottom of the movable groove, and the other end is connected to the pressure plate. One end of the guide rod is connected to the bottom of the movable groove, and the return spring is sleeved with the guide rod. The pressure plate has a limiting guide hole, and the other end of the guide rod is inserted into the limiting guide hole. The pressure plate has a ring-shaped structure and is fixedly sleeved on the connecting seat. The pressure plate compresses the return spring as the movable block moves downward, so that after the ball falls, the return spring resets the pressure block, raising the movable block (fixed block). This allows the movable block to quickly and automatically rotate and reset, allowing the feeding groove to refeed the ball. The pressure rod can move up and down along the guide rod to prevent the return spring from deforming. At the same time, the limiting guide hole improves the guiding nature of the pressure plate's up-and-down movement and horizontal rotation. The limiting guide hole has the same arc shape as the pressure plate as the movable block, further limiting the rotation path of the movable hole. This achieves the effects of stable connections between structures, improved operational efficiency, and enhanced operational accuracy.

[0017] Preferably, the storage tray is equipped with several support rods and a limiting guide groove. One end of each support rod is connected to a fixed block, and the other end is slidably connected to the limiting guide groove. The support rods are evenly distributed and connected to the inner wall of the storage tray. The limiting guide groove is a vertical recess on the surface of the storage tray. The other end of the support rod is inserted into the limiting guide groove to prevent the fixed block from rotating horizontally and affecting the rotation of the discharge through-hole to the relative position with the feed groove. At the same time, the length of the limiting guide groove limits the descent height of the fixed block. This further improves the structural connection stability and the ball bearing feeding accuracy.

[0018] Preferably, the storage tray is fitted with a second fixing screw, which is threadedly connected to the upper end face of the connecting seat. The connection between the storage tray and the upper end face of the connecting seat via the second fixing screw facilitates the assembly of the movable block, pressure plate, and guide slider with the connecting seat, confines the pressure plate within the movable groove, and simultaneously initiates disassembly. This improves the stability of the structural assembly and enhances the convenience of subsequent maintenance.

[0019] Preferably, the support base is connected to several support shafts, and the connecting base is plugged with a fixing screw three, which is threadedly connected to the support shafts. The connecting base is bolted to the support shafts via the fixing screw three, and the support shafts, supporting the connecting base, facilitate the insertion and removal of the ball bearing components to be assembled. This achieves the effect of improving the stability of the structural connection and the ease of operation.

[0020] The beneficial effects of this utility model are: simplifying the tooling structure and improving assembly convenience; achieving precise auxiliary ball positioning and quantitative assembly; improving automation and saving labor, thereby improving production efficiency; improving the smoothness of operation and facilitating transfer and maintenance; and improving the stability of structural connections.
