Technical Field
[0001] This utility model relates to the field of CNC vertical broaching machine technology, specifically a finished broaching fixture with a waterproof pressure cap. Background Technology
[0002] With the continuous upgrading of the manufacturing industry, components such as wheel hub bearings in automobiles were previously made by broaching individual wheel hub parts before assembling the bearings.
[0003] With the optimization of product structure and processing technology, some wheel hub bearing components need to be assembled into finished parts before broaching. Usually, a rubber ring is pressed on the top of the finished part before broaching. However, during the broaching process, the cutting fluid on the broach will always splash or drip into the bearing, affecting the product quality. Therefore, a finished broaching fixture with a waterproof pressure cap is proposed to solve the above-mentioned problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a finished broaching fixture with a waterproof pressure cap. It offers advantages such as preventing poor sealing between the finished part and the sealing ring during broaching, preventing residual cutting fluid from the broach through-hole in the pressure cap from dripping onto the finished part after broaching, and preventing residual cutting fluid from the sealing ring at the lower end of the pressure cap from dripping onto the finished part when the pressure cap is lifted. This solves the problem that when a rubber ring is pressed against the upper end of the finished part before broaching, the cutting fluid on the broach always splashes or drips into the bearing during broaching, affecting product quality.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a finished broaching fixture with a waterproof pressure cap, comprising a worktable, a pushing mechanism provided on the outer side of the worktable, a pressure cap lifting mechanism provided on the right side of the worktable, and a worktable cleaning mechanism provided on the outer side of the worktable;

[0015] Compared with the prior art, this utility model provides a finished broaching fixture with a waterproof pressure cap, which has the following beneficial effects:
[0016] 1. The finished broaching fixture with a waterproof cap has a raised flange and an O-ring A at the lower end of the waterproof cap, which can effectively prevent the cutting fluid from leaking out. After broaching, before opening the waterproof cap, use the cap air blower to blow away the cutting fluid remaining in the broach passage in the middle of the waterproof cap, so as to prevent the cutting fluid from dripping onto the finished part.
[0017] 2. This finished broaching fixture with a waterproof pressure cap allows for the removal of residual cutting fluid from the O-ring A area using an air nozzle after the pressure cap is opened, preventing cutting fluid dripping. During the broaching process, air blowers A and B remove residual water stains from the outer surface of the finished part while it is being moved to the intermediate pick-up position. The use of a ring sprayer and an oil pan effectively constrains water flow and collects splashed cutting fluid, solving the problem that cutting fluid on the broach would splash or drip into the bearing during broaching, even when a rubber ring was pressed against the top of the finished part before broaching, thus affecting product quality.

[0027] The working principle of the above embodiments is as follows:
[0028] Move to the broaching position: The pusher cylinder 13 drives the floating joint A11, the pusher connecting plate 10, the pusher plate 9 and the reference metal 31, together with the workpiece 21, to move along the horizontal rail 48 to the broaching center. During the movement, the air blowing block B39 installed at the front end of the pusher plate 9 blows air. At the same time, the scraper plates B38 and A32 at the front and rear ends of the pusher plate 9 clean the slide plate 35 and slide base 36 on the worktable 6 to keep them clean.
[0029] Air inspection: Perform air inspection on the broaching positioning surface of workpiece 21. If there are residual chips on the positioning surface, or if there are residual burrs on the workpiece causing unevenness of the positioning surface, the air inspection device will send a signal and stop the machine with an alarm.
[0030] Pressing down the workpiece for broaching: The lifting cylinder 1 drives the floating joint B44, lifting connecting block 43, lifting mounting bracket 42, pressure cover mounting plate 16 and waterproof pressure cover 23 to move downward along the vertical rail 45 to press down the workpiece 21. Then the ring spray body 14 and water spray pipe B47 spray out cutting fluid to broach the workpiece. After broaching is completed, the pressure cover blowing sleeve 15 introduces air to blow away the cutting fluid remaining in the hole of the waterproof pressure cover 21 to prevent the cutting fluid from dripping.
[0031] The waterproof cover is lifted: the lifting cylinder 1 drives the floating joint B44, the lifting connecting block 43, the lifting mounting bracket 42, the cover mounting plate 16 and the waterproof cover 23 to move upward. The air nozzle 8 installed on the side of the waterproof cover 23 blows air onto the lower end face of the waterproof cover 23 to remove the residual cutting fluid on the lower end face and prevent the cutting fluid from dripping onto the workpiece 21.
[0032] Workpiece moved to the intermediate transfer position for material removal: Push cylinder 11 drives the reference metal 31 on push plate 9, together with workpiece 21, to move to the left along horizontal rail 48. During the movement, air blowing block A30 installed on the left side of oil pan 27 blows air onto the upper end face of workpiece 21 to remove residual water stains. Workpiece 21 moves to the left intermediate transfer position, and workpiece 21 is removed, completing one broaching cycle.
[0033] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
