Description

A new type of scroll compressor scroll processing device

Technical field:

The utility model relates to a novel processing device for a scroll disc of a scroll compressor, which belongs to the technical field of scroll compressors.

Background technique:

The scroll needs to be milled on the machining center with the involute of the corrected circle. It is necessary to ensure that the center of the scroll line and the center of the scroll are in the same center. In this way, there are two requirements for the tooling: positioning and clamping. Pack.

The previous clamping method used a hydraulic or pneumatic high-precision chuck to clamp the maximum diameter of the scroll, and then processed after locking. This process is likely to cause repeated positioning errors of the scroll during clamping, poor consistency of the workpiece, and clamping. The workpiece is damaged, the parallelism of the scroll is very poor, the clamping has high requirements for the operator, the tooling is expensive, and the existing scroll is made of aluminum alloy, which is not only soft in texture, but also easy to deform, which is difficult to meet the current requirements. production needs.

Utility model content:

In view of the above problems, the technical problem to be solved by the utility model is to provide a new type of processing device for the scroll of a scroll compressor.

The utility model relates to a new processing device for the scroll disc of a scroll compressor, which includes a clamp base, a card slot, a pressure plate, a pin, a scroll disc, a scroll disc step, a sleeve, a sleeve keyway, and a clamp base There is a card slot on the top, and a pressure plate is arranged in the card slot, the pressure plate is connected with the cylinder main shaft, the cylinder main shaft is set in the fixture base, two pins are symmetrically arranged on both sides of the upper end surface of the fixture base, and the lower end of the scroll step faces The position of the pin should be provided with a pin hole, and the scroll step and the upper end surface of the fixture base are engaged with each other, the upper end of the scroll step is provided with a scroll, the lower end of the sleeve is provided with a sleeve keyway, and the sleeve The keyway of the sleeve corresponds to the position of the pressure plate and is sleeved on the fixture base, and the upper end of the sleeve and the step of the scroll disc are pressed against each other.

As a preference, the scroll is made of high-quality carbon structural steel, which has the functions of high strength, non-deformation and corrosion resistance.

Beneficial effects of the utility model: the structure design is reasonable, the operation is simple, and the use is convenient. By adopting the method of pulling down and locking the cylinder and the method of positioning the scroll disk, the error of repeated positioning is avoided, the cost is low, and no damage is caused when clamping. The workpiece has high positioning accuracy, good parallelism, convenient and fast clamping, small size, and multiple scrolls can be clamped at one time, which reduces the number of tool changes in the machine tool, improves the processing efficiency, and has high processing consistency.

Detailed ways:

As shown in Figures 1-8, this specific embodiment adopts the following technical solutions: it includes a clamp base 1, a slot 2, a pressure plate 3, a pin 4, a scroll 5, a scroll step 6, a sleeve 7, The sleeve keyway 8, the clamp base 1 is provided with a card slot 2, and the card slot 2 is provided with a pressure plate 3, the pressure plate 3 is connected with the cylinder main shaft, the cylinder main shaft is set in the clamp base 1, and the upper end surface of the clamp base 1 is arranged symmetrically on both sides There are two pins 4, and the lower end surface of the scroll step 6 is provided with a pin hole corresponding to the position of the pin 4, and the scroll step 6 and the upper end surface of the fixture base 1 are engaged with each other, and the scroll step 6 The upper end is provided with a scroll 5, and the lower end of the sleeve 7 is provided with a sleeve keyway 8, and the sleeve 7 is sleeved on the clamp base 1 through the position of the sleeve keyway 8 corresponding to the pressure plate 3, and the upper end of the sleeve 7 is in contact with the scroll. The disc steps 6 are pressed against each other.

Wherein, the scroll 5 is made of high-quality carbon structural steel, which has the functions of high strength, non-deformation and corrosion resistance.

When this specific embodiment is in use, when the cylinder moves downward, the pressure plate 3 will go down along the slot 2, thereby clamping the step at the lower end of the sleeve 7, and driving the sleeve 7 downward to move the lower end of the scroll 5 downward. The scroll step 6 is firmly fixed on the plane of the upper end of the clamp base 1 where the two pins 4 are located. Due to the ring-shaped downward pull, it is not like the previous tooling that uses three or four soft claws for clamping, only three points or Four points of force cause uneven force on the workpiece, pinch and bow deformation, etc., so the scroll 5 is evenly stressed and completely fits the plane where the two pins are located, with a very high degree of parallelism.

This specific embodiment has reasonable structural design, simple operation, and convenient use. By adopting the cylinder pull-down locking method and the scroll disk positioning method, the occurrence of repeated positioning errors is avoided, the cost is low, the workpiece is not damaged during clamping, and the positioning accuracy is high. High, good parallelism, convenient and fast clamping, small size, multiple scrolls can be clamped at one time, reducing the number of tool changes in the machine tool, improving the processing efficiency, and the processing consistency is extremely high.

The basic principles and main features of the present utility model and the advantages of the present utility model have been shown and described above. Those skilled in the art should understand that the utility model is not limited by the above-mentioned embodiments. The above-mentioned embodiments and descriptions only illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model The new model also has various changes and improvements, and these changes and improvements all fall within the scope of the claimed utility model. The scope of protection required by the utility model is defined by the appended claims and their equivalents.
