Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle production, in particular to a discharging device for processing a shift arm. Background Art

[0002] The shift arm is an important component of a motorcycle's speed shift operating system, used to connect the shift lever and the gearbox. However, since the shift arm is a non-standard part, the shift arm models equipped on different motorcycles are different, and the inclination of the drilling surface is different, resulting in different processing angles of the spring hanging holes on the shift arm; during the existing shift arm drilling processing, due to the irregular shape of the shift arm, different models of workpieces need to be designed with special types of fixtures, which has high fixture costs and high production costs, resulting in low economic benefits; and since the batch processing volume of a single model is not large, the processing of different models of products requires frequent manual replacement of fixtures and adjustment of equipment, resulting in low processing efficiency, and frequent adjustments make it difficult to ensure processing accuracy, affecting processing quality.

[0003] In response to the above phenomenon, the applicant has developed a rotary automated processing device that is compatible with multiple models of shift arms. The workpiece is driven by a dividing plate to rotate to various workstations for drilling, grinding and other processes, and then unloaded and collected. Currently, most unloading devices are manipulators or fixture structures. Although the manipulator is stable in grabbing and unloading, it also requires a large space to meet its movement trajectory. The overall structure of the processing device developed by the applicant is compact and cannot reserve a large space for the manipulator. The manipulator is prone to movement interference with other structures, and the cost of the manipulator is high. When using a fixture to unload, it is necessary to specially design the corresponding fixture. Not only is the structure complex, but different models require different fixtures, resulting in high overall production costs. Therefore, the applicant has designed a special unloading device for the shift arm to achieve low-cost and stable unloading. Utility Model Content

[0004] The utility model aims to provide a discharging device for machining a shift arm, so as to improve the stability of the discharging process of the shift arm.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a unloading device for shift arm processing, including a unloading unit and a positioning unit, the unloading unit includes a unloading jacking cylinder and a unloading cylinder, the movement paths of the two are perpendicular to each other, and the output shaft ends of the two are respectively connected to the jacking head and the unloading head; the positioning unit includes a positioning tool and a positioning magnet, the positioning magnet is an electromagnet and is respectively installed at the end of the jacking head and the unloading head, and the positioning tool is located between the unloading jacking cylinder and the unloading cylinder; positioning holes are opened at both ends of the positioning tool, and positioning pins are installed in the positioning holes.

[0006] The principles and advantages of this solution are:

[0007] 1. In actual application, compared with traditional manipulators or clamp structures that are prone to shaking when grasping irregularly shaped shift arms, resulting in unstable unloading, this solution introduces a positioning unit. The positioning tooling locates the workpiece before unloading, ensuring that the unloading unit accurately lifts and unloads the workpiece, and then uses positioning magnets to stably adsorb the workpiece. The magnetic adsorption enables the device to better adapt to the irregular shape of the shift arm, reduce shaking, and ensure the stability of the unloading process.

[0008] 2. The design of the unloading unit and positioning unit in this solution is relatively simple, and does not require a complex manipulator or fixture structure, which greatly simplifies the structure of the unloading device and reduces manufacturing and maintenance costs.

[0009] 3. Shift arms of different models have different shapes, and traditional unloading devices are difficult to be compatible with multiple models. The design of the positioning magnet enables the unloading device to adapt to shift arms of different shapes and sizes. Moreover, the electromagnet can adjust the adsorption force according to the characteristics of different shift arms, thereby better being compatible with multiple models of shift arms and enhancing the versatility and flexibility of the device.

[0010] 4. This unloading device can achieve an efficient unloading process through the vertical movement path of the lifting cylinder and the unloading cylinder, as well as the rapid adsorption and release of the electromagnet. The coordinated work of the two makes unloading faster and more accurate, thereby improving overall production efficiency.

[0011] Furthermore, the discharge head is provided with an avoidance component, which includes an avoidance guide rod that is vertically arranged and slidably connected in the discharge head, and a limit block is provided at the upper end of the avoidance guide rod.

[0012] The avoidance component design makes the space between the unloading head and the lifting head adjustable, which is convenient for adapting to shift arms of various models and different thicknesses, improving the versatility of the device and realizing the automation and standardization of shift arm processing.

[0013] Furthermore, a linear bearing is provided between the discharge head and the avoidance guide rod.

[0014] The linear bearing avoids direct contact between the unloading head and the avoidance guide rod, reducing the friction loss between the components, while ensuring the avoidance response speed and automatic reset speed of the avoidance guide rod, ensuring continuous unloading.

[0015] Furthermore, the positioning tool is provided with an avoidance groove for avoiding the output shaft of the blanking lifting cylinder, and the avoidance groove is arc-shaped.

[0016] The avoidance groove design avoids the movement interference between components and ensures the stability of the unloading jacking cylinder movement and the unloading process.

[0017] Furthermore, the positioning holes at either end of the positioning tool are multi-porous interconnected structures.

[0018] The above setting enables the positioning tool to determine the position of the positioning pin at the movable end according to the actual shift arm model, ensuring that multiple models of shift arms can be fixed on the positioning tool, realizing unified clamping and fixation of multiple products, and improving the versatility of the device.

[0019] Furthermore, the top of the positioning pin is conical.

[0020] The top of the locating pin is designed to be conical. One reason is to adapt to various types of shift arms and improve the versatility of the positioning tooling. The other reason is to reduce the positioning accuracy requirements between the workpiece and the positioning tooling. The conical design can increase the speed of workpiece clamping and thus improve processing efficiency.

[0021] Furthermore, the unloading unit also includes a unloading hopper, the hopper surface of the unloading hopper is an inclined surface, the unloading cylinder is installed on the unloading hopper, and when the output shaft of the unloading cylinder is fully retracted, the unloading head is located above the unloading hopper entrance.

[0022] The above arrangement not only reduces the overall space occupied by the device, but also enables the workpieces to be accurately and quickly collected along the discharge hopper after unloading, thereby preventing unloading accumulation and improving processing efficiency.

[0023] Figure 1 This is a schematic diagram of the unloading device located in the overall processing equipment.

[0024] Figure 2 This is a partial enlarged view of the unloading device.

[0025] Figure 3 This is a structural diagram of the assembly of the shift arm and positioning tooling. DETAILED DESCRIPTION

[0026] The following is further described in detail through specific implementation methods:

[0027] The figure marks in the drawings of the specification include: shift arm 100, unloading unit 1, unloading lifting cylinder 11, lifting head 12, unloading cylinder 13, unloading head 14, positioning unit 2, positioning tool 21, fixed end 211, movable end 212, positioning hole 213, positioning pin 214, avoidance groove 215, positioning magnet 22, avoidance assembly 3, avoidance guide rod 31, linear bearing 32, limit block 33, unloading hopper 4.

[0028] The embodiment is basically as shown in the attached Figure 1-Figure 3As shown: A discharge device for processing a shift arm, comprising a discharge unit 1 and a positioning unit 2. The discharge unit 1 comprises a discharge lifting cylinder 11 and a discharge cylinder 13, the motion paths of which are perpendicular to each other, and the ends of their output shafts are connected to a lifting head 12 and a discharge head 14, respectively. The positioning unit 2 comprises a positioning fixture 21 and a positioning magnet 22. The positioning magnet 22 is a cylindrical electromagnet and is mounted on the ends of the lifting head 12 and the discharge head 14, respectively. The positioning fixture 21 is located between the discharge lifting cylinder 11 and the discharge cylinder 13. Positioning holes 213 are formed at both ends of the positioning fixture 21, and positioning pins 214 are mounted in the positioning holes 213. The positioning fixture 21 is provided with an avoidance groove 215 for avoiding the output shaft of the discharge lifting cylinder 11. The avoidance groove 215 is arc-shaped to avoid motion interference between components and ensure the stability of the movement of the discharge lifting cylinder 11 and the discharge process.

[0029] The unloading unit 1 also includes a unloading hopper 4, which is fixed on the frame. The hopper surface of the unloading hopper 4 is an inclined surface. The unloading cylinder 13 is installed on the unloading hopper 4. The unloading lifting cylinder 11 is fixed on the frame. When the output shaft of the unloading cylinder 13 is fully retracted, the unloading head 14 is located above the entrance of the unloading hopper 4, which not only reduces the overall space occupied by the device, but also allows the workpiece to be accurately and quickly collected along the unloading hopper 4 after unloading, preventing unloading accumulation and improving processing efficiency.

[0030] The above-mentioned setting uses the positioning tool 21 to position the workpiece before unloading, ensuring that the unloading unit 1 accurately lifts and unloads the workpiece, and then stably adsorbs the workpiece through the positioning magnet 22. The magnetic adsorption enables the device to better adapt to the irregular shape of the shift arm 100, reduce shaking, and ensure the stability of the unloading process; moreover, the design of the positioning magnet 22 enables the unloading device to adapt to shift arms 100 of different shapes and sizes, and the electromagnet can adjust the adsorption force according to the characteristics of different shift arms 100, so as to better be compatible with various models of shift arms 100, thereby enhancing the versatility and flexibility of the device.

[0031] Preferably, the positioning hole 213 at either end of the positioning tool 21 is a porous interconnected structure, such as Figure 3 As shown, in this embodiment, the two ends of the positioning tool 21 are respectively a fixed end 211 and a movable end 212, and the positioning hole 213 located at the movable end 212 is a multi-porous connected structure, so that the position of the positioning pin 214 of the movable end 212 can be determined according to the actual model of the shift arm 100, ensuring that multiple models of shift arms 100 can be fixed on the positioning tool 21, realizing unified clamping and fixation of multiple products; and the top of the positioning pin 214 is conical, and the conical structure reduces the positioning accuracy requirements between the workpiece and the positioning tool 21, thereby improving the speed of workpiece clamping and processing efficiency.

[0032] like Figure 2As shown, the discharge head 14 is provided with an avoidance component 3, which includes a avoidance guide rod 31 vertically arranged and slidably connected in the discharge head 14, the upper end of the avoidance guide rod 31 is provided with a limit block 33, and the lower end is connected to the positioning magnet 22, and the limit block 33 limits the lowest position of the avoidance guide rod 31; the avoidance component 3 makes the space between the lifting head 12 and the discharge head 14 adjustable, which is convenient for adapting to various models and different thicknesses of shift arms 100, improving the versatility of the lifting device, and realizing the automation and standardization of the processing of the shift arm 100; a linear bearing 32 is provided between the discharge head 14 and the avoidance guide rod 31 to reduce the contact friction loss between the two and extend the service life of the parts.

[0033] The specific implementation process is as follows:

[0034] like Figure 3 As shown, the shift arm 100 has a large and a small circular hole at both ends thereof for cooperating with the two positioning pins 214 on the positioning tool 21 .

[0035] When the workpiece is above the entrance of the unloading hopper 4, the positioning magnet 22 on the unloading head 14 is turned off, and the workpiece falls into the unloading hopper 4 and is transported along the inclined hopper surface for collection, thereby completing the unloading of the workpiece.

[0036] The above description is merely an embodiment of the present invention, and the commonly known specific technical solutions and / or features of the solution are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be considered as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection claimed in this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
