Description

Technical Field

[0001] This utility model relates to the field of hole straightening equipment technology, specifically to an internal hole straightening device for processing motorcycle rocker arms. Background Technology

[0002] Motorcycle rocker arms usually refer to rear rocker arms, also known as rear swingarms, swingarms, rear forks, etc. They are an important part of the motorcycle suspension system. During the manufacturing process of motorcycle rocker arms, an internal hole straightening device is needed to process the inner hole of the motorcycle rocker arm. This device is a special equipment for precision correction, dimensional calibration, and shape correction of the machined or pre-machined inner hole to ensure that the inner hole meets the high-precision fit standard required by the design.

[0003] To address this, the China Patent Network discloses an internal hole straightening device for machining motorcycle rocker arms, application number: 202421041975.4. A hydraulic cylinder drives a pressure plate to descend and press against the motorcycle rocker arm, thus confining the rocker arm within a positioning groove. A first motor drives a lead screw to rotate, and the lead screw thread drives a slider to descend, which in turn drives a second motor to descend. The second motor drives the straightening head to continuously cut the internal hole of the motorcycle rocker arm, and the cutting debris falls onto a filter plate for collection. The operation is convenient and quick, with high straightening efficiency. Simultaneously, a water pump draws cold water from the bottom of the water collection tank and sprays it to the cutting position through a nozzle, which cools the high-speed rotating straightening head to prevent overheating and ensure the straightening effect.

[0004] While the above-mentioned applications meet the user's needs to a certain extent, certain defects still exist during use. The specific problems are as follows: when fixing the motorcycle rocker arm, the simultaneous activation of the two hydraulic cylinders increases the manufacturing cost and the probability of failure of the equipment. At the same time, due to the possible slight differences in the pipeline resistance and sealing performance of the two hydraulic cylinders, problems such as asynchronous operation and inconsistent pressure are very likely to occur in actual operation, making it difficult to guarantee positioning accuracy and consistency, thus affecting the processing efficiency and effect of straightening the inner hole of the motorcycle rocker arm. Based on this, this utility model designs an inner hole straightening device for processing motorcycle rocker arms to solve the above problems. Summary of the Invention

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-7 This utility model provides a technical solution: an inner hole straightening device for processing motorcycle rocker arms, including a base 1, and an adjusting straightening assembly 2 is provided above the base 1. The adjusting straightening assembly 2 includes a moving table 201, a straightening head 203, a straightening seat 204, a nozzle 206 and a pressure plate 212. A movable platform 201 is slidably connected inside the base 1. A straightening head 203 is provided below the movable platform 201. A straightening seat 204 is fixedly connected to one side of the base 1. A nozzle 206 is symmetrically fixedly connected inside the base 1. The nozzle 206 penetrates the interior of the base 1 to facilitate cooling of the contact point between the high-speed rotating straightening head 203 and the inner wall of the rocker arm, thereby extending the service life of the straightening head 203. Two pressure plates 212 are provided above the straightening seat 204. The adjusting and straightening assembly 2 also includes a drive motor 202, a through hole 205, a connecting rod 207, a transmission gear 208, a bevel gear set 209, a threaded rod 210, a sleeve 211, a first motor 213, a transmission lead screw 214, and a water tank 215. A drive motor 202 is fixedly installed inside the moving stage 201. The drive motor 202 is electrically connected to the output terminal of an external power supply. The output shaft of the drive motor 202 is fixedly connected to the straightening head 203. A through hole 205 is opened inside the straightening seat 204. A connecting rod 207 is symmetrically rotatably connected inside the base 1 and the straightening seat 204. A first motor 213 is fixedly installed inside and at the top of the base 1. The first motor 213 is electrically connected to the output terminal of an external power supply. A transmission screw 214 is fixedly connected to the output shaft of one first motor 213. The transmission screw 214 is threadedly connected to the moving stage 201. The output shaft of the other first motor 213 is fixedly connected to the outer side of the connecting rod 207. A transmission gear 208 is fixedly connected to the base 1. The three transmission gears 208 mesh with each other. A bevel gear set 209 is fixedly connected to one side of the connecting rod 207. The bevel gear set 209 consists of two meshing bevel gears. A threaded rod 210 is fixedly connected to the top of the bevel gear set 209. A sleeve 211 is threadedly connected to the outside of the threaded rod 210. The top of the sleeve 211 is fixedly connected to the pressure plate 212, which facilitates the positioning of both sides of the top of the motorcycle rocker arm and ensures its machining accuracy. A water tank 215 is fixedly connected to one side of the base 1. A water pump is fixedly installed inside the water tank 215 and communicates with the inside of the two nozzles 206. A water inlet pipe and a water outlet pipe are fixedly connected to both sides of the water tank 215, respectively. The motorcycle rocker arm is placed on the top of the straightening seat 204. After the through hole 205 is aligned with the position of the hole to be straightened, a first motor 213 is started. The first motor 213 drives a transmission gear 208 to rotate, and through mutual meshing, it drives the other two transmission gears 208 to rotate simultaneously. The transmission gears 208 drive the two connecting rods 207 to rotate simultaneously. The connecting rods 207 drive the bevel gear set 209 and the threaded rod 210 to rotate, causing the sleeve 211 to drive the pressure plate 212 to move, simultaneously applying pressure to the top ends of both ends of the rocker arm, completing the positioning of the rocker arm, and ensuring that there is no displacement or deformation during the processing. The other motor 213 and drive motor 202 are started, which drive the transmission screw 214 to rotate. This causes the moving table 201 to move the straightening head 203 closer to the motorcycle rocker arm and embed it into the inner hole of the rocker arm through the through hole 205. The drive motor 202 drives the straightening head 203 to rotate at high speed to correct the precision of the pre-machined inner hole. At this time, the water pump in the water tank 215 is started, and cold water is sprayed out directionally through the symmetrically arranged nozzles 206. The water is precisely sprayed to the contact point between the straightening head 203 and the inner wall of the rocker arm, which quickly removes the cutting heat and avoids overheating and wear of the tool or thermal deformation of the workpiece. At the same time, it helps to flush away the chips.

[0016] An anti-clogging collection assembly 3 is provided above the base 1. The anti-clogging collection assembly 3 includes a collection box 301, a filter plate 302, a brush plate 305, and a rotating shaft 307. A collection box 301 is fixedly connected to one side of the base 1, and a drain pipe is fixedly connected to one side of the collection box 301 to facilitate the discharge of sewage. A filter plate 302 is slidably connected inside the collection box 301, and a brush plate 305 is slidably connected inside the base 1. The brush plate 305 contacts the top of the filter plate 302. Rotary shafts 307 are rotatably connected to both sides inside the collection box 301.

[0017] The anti-blocking collection assembly 3 also includes a fixed box 303, a reciprocating lead screw 304, an inclined plate 306, a torsion spring 308, a stopper plate 309, and a rotary motor 310; Both sides of the collection box 301 are fixedly connected to fixed boxes 303. The fixed box 303 has a movable door inside. The fixed box 303 has a slanted panel 306 fixedly connected inside. The base 1 is rotatably connected to a reciprocating screw 304. A torsion spring 308 is fixedly sleeved on the outside of the rotating shaft 307. A stop plate 309 is fixedly connected to the outside of the rotating shaft 307. A rotary motor 310 is fixedly installed on one side of the base 1. The rotary motor 310 is electrically connected to the output terminal of an external power supply. The output shaft of the rotary motor 310 is connected to the outside of the reciprocating screw 304 through a belt drive mechanism. The belt drive mechanism consists of two drive wheels and a belt, which facilitates the movement of the brush plate 305. Metal scraps generated during processing slide down the cooling water through the through-hole 205 and the straightening seat 204 into the collection box 301, falling onto the surface of the filter plate 302. The filter plate 302 intercepts the scraps, while the cooling waste liquid flows through the pores of the filter plate 302 into the bottom of the collection box 301 and is finally discharged through the drain pipe. The rotary motor 310 is started, and its output shaft drives the reciprocating screw 304 to rotate via a belt drive mechanism. The reciprocating screw 304 drives the brush plate 305 to move horizontally back and forth along the inside of the collection box 301. The brush plate 305 and the filter plate 302... When the brush plate 305 moves, it pushes the accumulated debris to squeeze the plug plate 309, sweeping the debris attached to the surface of the filter plate 302 into the fixed box 303, thus preventing the pores of the filter plate 302 from being blocked. The rotating shaft 307, under the action of the torsion spring 308, drives the plug plate 309 to remain closed, preventing waste liquid leakage. The inclined panel 306 allows the debris to accumulate towards the movable door. By opening the movable door, the debris in the fixed box 303 can be cleaned. After the work is completed, the filter plate 302 can be pulled out for cleaning for the next use.
