Description

Technical Field

[0001] This utility model relates to the field of synchronizer assembly equipment, and more specifically to a tooling that facilitates synchronizer assembly. Background Technology

[0002] The synchronizer is a key component in a car transmission, primarily used to eliminate gear speed differences and ensure that the gears to be engaged rotate at the same speed during gear shifting, thereby avoiding impact, gear grinding, and power interruption. Its core principle is to achieve speed synchronization through frictional torque. The synchronizer consists of a gear hub, gear sleeve, spring, and locking pin. When assembling a synchronizer, workers need a tooling adapted to that model to easily fix the components, speed up assembly, and improve yield. However, after prolonged use, existing tooling accumulates a large amount of impurities such as metal shavings and oil in its gaps. Excessive accumulation of these impurities can easily cause wear on the tooling and gear sleeve, affect installation accuracy, and make subsequent cleaning difficult. Utility Model Content

[0003] This invention provides a tooling for facilitating synchronizer assembly, which can automatically clean impurities from the tooling gaps and avoid affecting synchronizer installation.

[0004] A tooling for facilitating the assembly of synchronizers includes a mounting platform with multiple locking blocks on the platform and multiple limiting blocks on the edge of the platform. Each limiting block corresponds to a position of one of the locking blocks. Each locking block has multiple air holes, and each air hole extends to the axis of the mounting platform. A connecting pipe is fixedly connected to the lower end of the mounting platform, and the connecting pipe communicates with the multiple air holes.

[0005] Each limit block has a dovetail groove, and an additional block is slidably connected in each dovetail groove.

[0006] Each card block surface is covered with an anti-wear pad.

[0007] A telescopic plate is fixedly connected to the lower end of the mounting platform. A sliding sleeve is fitted over the telescopic plate, and the telescopic plate is slidably connected inside the sliding sleeve.

[0008] The telescopic plate has multiple mounting holes, and the sliding sleeve has positioning holes.

[0009] The slide sleeve is fixedly connected to a base and a clamp.

[0010] The base has a threaded hole, and a screw is threaded into the threaded hole. A pressure plate is fixedly connected to the upper end of the screw.

[0011] A handle is fixedly connected to the lower end of the screw.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific implementation methods.

[0015] Figure 1 and Figure 2 This is a schematic diagram of the overall structure of a tooling system that facilitates the assembly of synchronizers.

[0016] Figure 3 This is a sectional view of the mounting platform.

[0017] Figure 4 This is a schematic diagram of the clamping plate. Detailed Implementation

[0018] A tooling for assembling synchronizers includes a mounting platform 101, on which multiple locking blocks 102 are provided, and multiple limiting blocks 103 are provided on the edge of the mounting platform 101. The multiple limiting blocks 103 correspond one-to-one with the positions of the multiple locking blocks 102. Multiple air holes 202 are opened on the multiple locking blocks 102, and each air hole 202 extends to the axis of the mounting platform 101. A connecting pipe 201 is fixedly connected to the lower end of the mounting platform 101, and the connecting pipe 201 communicates with the multiple air holes 202.

[0019] See Figure 1-3 ,

[0020] When using the tooling, the operator first places the synchronizer's gear sleeve onto multiple locking blocks 102. The multiple locking blocks 102 serve to position the gear sleeve, thereby ensuring that the axis of the gear sleeve coincides with the axis of the mounting platform 101, preventing installation misalignment. After the mounting platform 101 is installed, the operator installs the locking pin, spring, and gear hub onto the gear sleeve, thus completing the installation of the synchronizer.

[0021] Multiple limiting blocks 103 further limit the gear sleeve, thus preventing slight displacement. During synchronizer installation, the operator connects the connecting pipe 201 to the air pump, and the pump delivers air through the connecting pipe 201 to multiple air holes 202. Finally, high-pressure air is ejected through the multiple air holes 202. Since the multiple air holes 202 are respectively opened on multiple locking blocks 102, and the multiple limiting blocks 103 correspond one-to-one with the positions of multiple locking blocks 102, the discharged air can impact the area between the limiting blocks 103 and the locking blocks 102 under pressure, thereby removing residual impurities in the area of ​​the limiting blocks 103 and the locking blocks 102, preventing impurities from accumulating in this area and causing wear on the subsequent gear sleeve. The dirt formed by the accumulation of impurities increases the cleaning difficulty for the operator, while this device facilitates cleaning and further reduces the workload.

[0022] The air pump intermittently sprays air to clean the gaps, ensuring cleaning effectiveness while reducing energy consumption.

[0023] Each limiting block 103 is provided with a dovetail groove 104, and an additional block 105 is slidably connected in each dovetail groove 104.

[0024] See Figure 1 ,

[0025] By inserting the protrusion on the additional block 105 into the dovetail groove 104, the additional block 105 is fixed on the limiting block 103, thereby increasing the thickness of the limiting block 103, which facilitates the limiting of tooth sleeves of different thicknesses and improves the application range of the tooling.

[0026] Each card block 102 has an anti-wear pad attached to its surface.

[0027] See Figure 3 ,

[0028] The anti-wear pad protects the inner ring of the gear sleeve, preventing it from coming into contact with impurities and causing wear.

[0029] A telescopic plate 301 is fixedly connected to the lower end of the mounting platform 101. A sliding sleeve 303 is fitted over the telescopic plate 301, and the telescopic plate 301 is slidably connected inside the sliding sleeve 303.

[0030] See Figure 4 ,

[0031] By adjusting the extension length of the telescopic plate 301 within the sliding sleeve 303, the height of the mounting platform 101 can be adjusted, making it suitable for different working scenarios and for different workers, thereby further improving the applicability of this tooling.

[0032] The telescopic plate 301 has multiple mounting holes 302, and the sliding sleeve 303 has positioning holes 304.

[0033] See Figure 4 ,

[0034] After the height of the mounting platform 101 is adjusted to a suitable position, the staff inserts the positioning pins into the corresponding mounting holes 302 and positioning holes 304 to fix the telescopic plate 301 and the sliding sleeve 303.

[0035] A base 401 and a clamping plate 402 are fixedly connected to the sliding sleeve 303.

[0036] See Figure 4 ,

[0037] The base 401 and the clamping plate 402 work together to secure the mounting platform 101 to the workbench, thereby preventing the mounting platform 101 from shaking and making the mounting platform 101 more stable during use, reducing the frequency of operator errors.

[0038] The base 401 has a threaded hole, and a screw 404 is threaded into the threaded hole. A pressure plate 405 is fixedly connected to the upper end of the screw 404.

[0039] See Figure 4 ,

[0040] After the desktop is inserted between the base 401 and the clamping plate 402, the operator rotates the screw 404 to move the pressure plate 405 upward. The pressure plate 405 then works with the clamping plate 402 to clamp the desktop, thereby fixing the mounting platform 101. At the same time, this structure facilitates the disassembly and movement of the mounting platform 101, improving portability.

[0041] A handle 406 is fixedly connected to the lower end of the screw 404.

[0042] See Figure 4 ,

[0043] The handle 406 facilitates manual operation of the screw 404 by staff, improving convenience.

[0044] A rubber sleeve 407 is fixedly connected to the upper end of the pressure plate 405.

[0045] See Figure 4 ,

[0046] The rubber sleeve 407 is made of rubber and serves to protect the pressure plate 405 and the tabletop, preventing scratches caused by hard contact.

[0047] A protective pad 403 is fixedly connected to the lower end of the clamping plate 402. The protective pad 403 is corrugated.

[0048] See Figure 4 ,

[0049] The protective pad 403 is made of rubber. The corrugated protective pad 403 can increase the friction between the clamp 402 and the tabletop, while also protecting the clamp 402 and the tabletop to prevent wear.
