Description

Technical Field

[0001] The utility model relates to the technical field of clamping tooling, in particular to a casting clamping tooling that solves the problem of pressure plate balance. Background Art

[0002] The pressure plate is an important component of the clutch assembly. Generally, the pressure plate needs to be tested for static balance after turning. The imbalance amount generally does not exceed 500g•mm. For the part exceeding 500g•mm, it is necessary to drill a balancing deweighting hole in the heavier direction to make the imbalance amount of the pressure plate meet the use requirements (≤500g•mm). In the above process, even if the balancing deweighting hole is drilled, the balance amount may not meet the standard (>500g•mm), and the product can only be scrapped. To address this phenomenon, by collecting the balance data of batch products, the law of pressure plate overweight is found, and the positioning reference is corrected in advance on the casting mold. Within the tolerance range, the heavier side is allowed to turn a certain amount of weight during turning, which can solve the pressure plate balance problem. The pressure plate needs to use clamping tooling when turning.

[0003] During use, the existing pressure plate clamping fixture is usually fixed by bolts. If it is necessary to replace the clamping fixture of different specifications according to changes in the production process or the size specifications of different pressure plates, it will be very troublesome because the bolts need to be removed and reinstalled. This process is not only time-consuming and labor-intensive, but may also affect the production schedule. Therefore, we have introduced a new casting clamping fixture to solve the pressure plate balance problem. Utility Model Content

[0030] In this embodiment, the connecting mechanism 5 includes a connecting block 51, and positioning grooves 52 are provided on the front and rear of the outer surface of the connecting block 51, and movable grooves 53 are provided on the inner left and right parts of the connecting block 51. The inner walls of the two movable grooves 53 are fixedly connected with springs 54, and the ends of the two springs 54 away from the inner walls of the movable grooves 53 are fixedly connected with movable blocks 55, and the ends of the two movable blocks 55 away from the springs 54 are fixedly connected with limiting blocks 56. The connecting block 51 is engaged with the connecting groove 2, and the upper end of the connecting block 51 is fixedly connected with the clamping disk 6. The two positioning grooves 52 are respectively engaged with the two positioning bars 3, and the two movable blocks 55 are respectively located inside the two movable grooves 53, and the ends of the two limiting blocks 56 away from the movable block 55 are respectively interlaced with the two limiting grooves 4.

[0031] Through the above scheme: by applying force to the two limit blocks 56, the two limit blocks 56 are moved into the two movable grooves 53 respectively and the spring 54 is compressed, and then the connecting block 51 is snapped into the inside of the connecting groove 2, and at the same time the two positioning strips 3 are respectively engaged with the two positioning grooves 52. Under the reset of the spring 54, the two limit blocks 56 are respectively popped out from the corresponding two limit grooves 4, so that the clamping plate 6 can be easily and quickly installed, and it is also convenient to quickly replace clamping plates 6 of different specifications and types.

[0032] In this embodiment, the clamping mechanism 7 includes a fixed block 71, a cylinder 72 is fixedly installed on the left end of the fixed block 71, the output end of the cylinder 72 is fixedly connected to the clamping block 73, the middle part of the lower end of the clamping block 73 is fixedly connected to the slider 74, the side of the clamping block 73 away from the cylinder 72 is fixedly connected to the clamping pad 75, the lower end of the fixed block 71 is fixedly connected to the clamping disk 6, the lower end of the clamping block 73 does not contact the clamping disk 6, the slider 74 is slidably connected to the slide groove 8, and the clamping pad 75 is made of rubber material.

[0033] Through the above scheme: the clutch pressure plate is placed on the clamping plate 6, and by starting the three cylinders 72, the three cylinders 72 respectively push the three clamping blocks 73 to move closer to each other, so that the three clamping pads 75 are all fitted and clamped with the clutch pressure plate, so that the clutch pressure plate can be quickly fixed on the clamping plate 6, which is convenient for turning operations on the clutch pressure plate, and the clamping pads 75 are made of rubber material, which can effectively avoid scratches and other damages to the surface of the pressure plate.

[0034] It should be noted that the present invention is a casting clamping fixture that solves the problem of pressure plate balance. During use, by applying force to the two limit blocks 56, they can be prompted to slide into the two movable grooves 53 respectively and compress the springs 54 therein. Subsequently, the connecting block 51 is snapped into the interior of the connecting groove 2, while ensuring that the two positioning strips 3 are engaged with the corresponding two positioning grooves 52. At this time, the spring 54 will push the two limit blocks 56 to pop out from their respective limit grooves 4 due to the reset effect, which facilitates the rapid installation and replacement of the clamping disc 6. No matter what specifications or types of clamping disc 6 are, it can be easily handled. Due to the high efficiency of the installation process, the downtime required for replacing the clamping disc 6 on the production line has been greatly reduced. This is crucial for a large-scale, high-efficiency production environment, because reducing downtime means increasing valuable effective production time, thereby improving output and economic benefits. After the clamping plate 6 is installed, the clutch pressure plate is placed on the clamping plate 6. At this time, the three cylinders 72 are started, and they will work together to push the three clamping blocks 73 closer to each other and move until the three clamping pads 75 are tightly fitted and clamped with the clutch pressure plate. In this way, the clutch pressure plate can be quickly and firmly fixed on the clamping plate 6, which provides great convenience for subsequent turning operations. The clamping pad 75 is made of rubber, which can effectively prevent scratches or other forms of damage to the pressure plate surface during the clamping process.
