Detailed Description

The following detailed description of the embodiments of the present utility model is provided with reference to the accompanying drawings, so that the technical scheme of the present utility model is easier to understand and grasp, and the protection scope of the present utility model is defined more clearly.

The designer aims at the problem that the cutter vibration phenomenon is generated due to the thin-wall characteristics of the traditional battery water-cooling plate when the traditional battery water-cooling plate is processed by a main shaft, and then cutter vibration lines appear on a processing surface, and innovatively provides a flexible follow-up pinch roller assembly according to the characteristics of the product and the stress analysis research so as to improve the processing surface.

Firstly, the battery water-cooling plate to be processed is formed by welding a plurality of layers of metal plates from the characteristic of the battery water-cooling plate. As shown in fig. 1, the processing target is two sides of the surface of the battery water cooling plate 2, and is formed into a flat groove 21; and one end corresponding to the front side of the battery water cooling plate in the feeding direction is formed into a step part which is thickened step by step. Therefore, the transitional action of the pressing action when the battery water cooling plate is contacted needs to be considered and considered, and the possibility of product pressure loss is eliminated. As peripheral accessories and function optimization of the production line spindle 1, the flexible follow-up pinch roller assembly has the main functions of absorbing vibration generated in the milling process of the surface of the battery water cooling plate by the machining tool bit 11 and pressing and stabilizing a workpiece at a position close to a machining point. From the general structural features, as shown in fig. 1-2, the preferred embodiment provides two puck assemblies on either side of the spindle to achieve a slightly functionally differentiated hold down operation. From the common structural features of the embodiment shown in fig. 2, the puck assembly 3 is composed of a linear guide rail 31, a cylinder 32, a puck mounting main seat 33 and a puck unit 34, wherein the cylinder 32 is fixedly connected to the top end of the linear guide rail 31, and the backside of the puck mounting main seat 33 is formed into a slider and is sleeved on the linear guide rail 31. The front side of the main pressing wheel mounting seat 33 is connected with the output shaft of the air cylinder 32 and driven to slide. The pinch roller unit 34 is attached to the bottom side of the pinch roller mounting main base 33 and is lifted synchronously therewith, and the bottom side of the pinch roller unit 34 is provided with more than one driven pulley. In the pinch roller assembly, a corresponding pinch roller unit is driven by a cylinder matched with the pinch roller assembly to carry out floating lifting, and a pressing force is applied to the projection direction when required. The air cylinder is provided with a throttle valve, and the air cylinder is driven by an externally connected air source and a controller thereof to downwards output an adjustable driving force.

The above-mentioned common structural feature further includes that the output shaft of the corresponding cylinder 32 is connected with a floating joint 35 and a T-pillar (not identified) with its end inverted, while the top of the pinch roller mounting main seat 33 is connected with a floating joint connection block 36 and a docking slot thereof, and the T-pillar is slidably engaged in the docking slot, thereby transmitting the driving force outputted from the cylinder upward or downward in a direction parallel to the linear guide rail.

In addition to the above common structural features, various puck assemblies have varying implementation profiles and structural compositions based on the application function bias. For example, the pinch roller unit may be configured as a single wheel when it is primarily adapted to contact the battery water-cooled plate and to be easily rolled on its surface, and the sub-unit may be configured as a single row of pinch roller sets when it is adapted for direct compression from top to bottom and for low resistance relative displacement. Accordingly, various alternative structural components of the puck assembly are described in detail below in conjunction with the figures, respectively.

Example 1

Based on the above common structural features, as shown in fig. 2, the pinch roller unit 34 is a crank single wheel biased to approach the main shaft, and comprises a crank 341 and a driven pulley 342, wherein a wheel post 3411 is formed at the end of the crank 341, and only one driven pulley 342 is sleeved on the wheel post 3411 and is limited and prevented from falling off. In this way, the driven pulley can freely rotate around the wheel post in a free empty state, and the relative displacement with low resistance can be maintained after the surfaces of the battery water cooling plates are contacted. Because the pinch roller assembly is mainly used for pre-compacting the battery water-cooling plate to be processed and milling the battery water-cooling plate by the processing cutter head immediately after the battery water-cooling plate is processed, the driven pulley of the pinch roller assembly should be close to the processing cutter head at a smaller distance as much as possible so as to weaken the vibration of a product to the greatest extent; otherwise, if the distance between the two is larger, the weakening effect on the vibration of the product is obviously reduced under the condition that the product is not damaged by pressure. In this embodiment, the pressing force of the crank arm single wheel to the product to be processed is only related to the output driving force of the cylinder 32, and is adjustably set by the throttle 321.

Example two

As shown in fig. 3, on the basis of the preferred embodiment shown in fig. 2, a through hole is formed at the bottom side of the main pressing wheel mounting seat 33, a stud extending into the through hole and penetrating out is formed at the top of the crank arm 341 of the pressing wheel unit (still being a crank arm single wheel), a spring 37 and a nut are sleeved on the exposed section of the stud, two ends of the spring 37 are abutted against the floating joint connecting block 36 and the nut, and sliding driving force and elastic pressing force are transmitted to the pressing wheel unit through the spring. The implementation structure and function of the puck unit are largely the same or described with reference to embodiment one. In contrast, in the present embodiment, the pressing force of the crank arm for the product to be processed is changed in association with not only the output driving force of the cylinder 32 but also the return elastic force of the spring. The cylinder outputs driving force for driving the pinch roller unit to lift by the pinch roller mounting main seat, and when the single crank wheel contacts with a product, extra pressing force is applied to the product under the action of spring reset force in a very small stroke range; but also fine tuning the spring tension by means of nuts.

Example III

As shown in FIG. 4, another preferred embodiment of the puck assembly 4 has the following common structural features: the device is formed by the attachment of a linear guide rail 41, an air cylinder 42, a pinch roller mounting main seat 43 and a pinch roller unit 44; the pinch roller assembly 4 is also provided with a floating joint 45 and a floating joint connection block 46, and the function of transmitting the driving force of the cylinder is achieved in the same manner as described above. As compared to the two embodiments described above, it is apparent from the illustration that the pinch roller unit 44 is a single row of pinch roller sets attached side by side to the cover plate 441 by a plurality of driven pulleys 442. The bottom side of the cover 441 is formed with a plurality of co-planar and parallel wheel posts 4411, while the driven pulleys 442 are sleeved on the wheel posts 4411 one by one and are limited and prevented from falling off, and adjacent driven pulleys are in clearance fit and do not interfere with each other. Therefore, when the single-row pressing wheel contacts the surface of the product and applies pressing force, the product is pressed in a front-back distribution mode along the machining direction by multiple points (the number of the points is four in the drawing).

In addition, in this embodiment, the cover plate 441 is integrally connected with the main pressing wheel mounting seat 43 through the connecting shaft 47, and the main pressing wheel mounting seat is provided with a fastening screw 48 vertically propping against the connecting shaft and fastening nuts 49 at two ends thereof at opposite sides, so as to adjust and lock the vertical degree of the bottom surface of the single-row pressing wheel set and the linear guide rail, and avoid contact cavities between the single-row pressing wheel set and the battery water cooling plate.

In addition to the above embodiments, as a popular preferred arrangement, a CCD monitor with a downward viewing angle may be further connected to the side of the main base for installing the pressing wheel, so as to assist signals to drive the corresponding cylinders to act, output driving force or control reset.

In summary, the present utility model has been described in detail with reference to the embodiments of the puck assembly, and the present utility model has substantial features and advantages: based on the fact that the pressing wheel assemblies are arranged on one side or two sides of the main shaft at the same time, reliable and balanced pressing effect can be applied to the whole milling operation process of the machining tool bit facing the battery water cooling plate, product vibration can be eliminated, and therefore flatness of machining flat grooves and product yield are improved greatly.

In addition to the above embodiments, other embodiments of the present utility model are possible, and all technical solutions formed by equivalent substitution or equivalent transformation are within the scope of the present utility model as claimed.
