[0002] Plastic bottles have important applications in the field of liquid packaging. Among them, the blow molding machine is the equipment for manufacturing plastic bottles. The core component of the blow molding machine is the frame of the blow molding machine, which carries the plastic bottle forming mold (consisting of left, right and bottom molds). These single-mold and single-cavity frames are assembled in the main frame and accurately positioned by the indexing plate. During high-speed operation, the frame not only supports the weight of the mold frame and mold, but also bears the workload. Therefore, the quality of the frame is directly related to the stable operation, efficiency and durability of the blow molding machine.

[0003] In the process of manufacturing the frame, since the frame is made of cast blanks, the shape is irregular and the distribution of casting allowances varies greatly, there is no flat clamping reference surface, and manual repeated positioning is required during the processing, resulting in low production efficiency of the frame.

[0004] Therefore, a processing method of a bottle blowing machine frame is needed to solve the above problems. Summary of the invention

[0014] In some embodiments, in step S1, a first center cross line is drawn on one side of the frame blank to determine the first positioning point, and a second center cross line is drawn on the other side of the frame blank to determine the second positioning point.

[0015] In some embodiments, in step S2, a height gauge is used to adjust the adjustment support seat.

[0016] In some embodiments, the height gauge is disposed on the adjustment support seat.

[0017] In some embodiments, a plurality of the height scales are spaced apart on the adjustment support seat.

[0018] In some embodiments, in step S4, a bottom hole is machined on the end face of the frame blank.

[0019] In some embodiments, in step S5, a fastening bolt is passed through the first process hole to fix the frame blank on the roughing fixture.

[0032] In the process of processing the frame of the bottle blowing machine, in order to improve the processing efficiency of the frame, such as Figure 1 As shown, the present invention provides a method for processing a frame of a bottle blowing machine. The method for processing a frame of a bottle blowing machine comprises the following steps:

[0033] S1. Draw a reference line on the frame blank, and draw a first positioning point and a second positioning point on both sides of the frame blank;

[0034] S2, placing the frame blank on the adjustment support seat of the milling reference fixture, and adjusting the adjustment support seat so that the reference line of the frame blank is in a horizontal state;

[0035] S3, using the top of the fixed rod on the milling reference fixture to abut against the first positioning point, the movable top on the milling reference fixture to abut against the second positioning point, and fixing the frame blank on the milling reference fixture;

[0036] S4, using processing equipment to mill a first reference surface on the frame blank and process a first process hole;

[0037] S5, using the first reference surface and the first process hole for positioning, fixing the frame blank on the roughing fixture, rough milling the frame blank, fine milling the second reference surface and processing the second process hole;

[0038] S6. Using the second reference plane for positioning, fix the frame blank on the finishing fixture through the second process hole, finish-process the frame blank, and complete the processing of the frame.

[0039] By designing the processing procedure in the above manner, the frame blank is accurately positioned using the reference line, the first positioning point and the second positioning point, and then the first reference surface and the first process hole are processed. The second reference surface and the second process hole are positioned and processed using the first reference surface and the first process hole, and the frame blank is finely processed. The processing accuracy can be guaranteed, and each process has accurate positioning, and there is no need to repeatedly adjust the positioning position, which can improve the processing efficiency of the frame.

[0040] In some embodiments, in step S1, a first center cross line is drawn on one side of the frame blank to determine the first positioning point, and a second center cross line is drawn on the other side of the frame blank to determine the second positioning point. In this way, it is convenient for the fitter to machine and mark the first positioning point and the second positioning point on the frame blank.

[0041] In some embodiments, in step S2, a height gauge is used to adjust the adjustable support seat. By using a height gauge for measurement, it is possible to ensure that the reference line remains horizontal, thereby facilitating the adjustment of the adjustable support seat so that the final bracket blank is in a horizontal state for processing.

[0042] In some embodiments, the height gauge is arranged on the adjusting support seat. By integrating the height gauge on the adjusting support seat, in the process of fixing the supporting bracket blank, there is no need to search on site, which can save time for adjusting the adjusting support seat, thereby improving the processing efficiency.

[0043] In some embodiments, a plurality of height gauges are arranged at intervals on the adjusting support seat. By arranging a plurality of height gauges, it is convenient to measure different positions of the bracket blank, so as to quickly determine the horizontality of the reference line.

[0044] In some embodiments, in step S4, a bottom hole is processed on the end face of the frame blank. In the process of processing the first process hole and the first reference surface, the bottom hole is processed at the same time, so that the processing of the first process hole, the first reference surface and the bottom hole is completed by one clamping and positioning. Repeated clamping and positioning are avoided, so that the processing efficiency can be guaranteed, and the error caused by repeated positioning can be eliminated. In this embodiment, the processing equipment is a processing center, which can simultaneously complete milling, drilling, turning and other processes.

[0045] In some embodiments, in step S5, a fastening bolt is passed through the first process hole to fix the frame blank on the roughing fixture. In this way, the frame blank can be stably fixed on the roughing fixture, and the frame blank will not shake during subsequent processing.

[0046] In some embodiments, in step S6, a fastening bolt is passed through the second process hole to fix the frame blank on the finishing fixture. In this way, the frame blank can be stably fixed on the finishing fixture, and the frame blank will not shake during subsequent processing.

[0047] In some embodiments, a fixture motherboard is installed for the rotary table of all processing equipment, the origin coordinate value of the fixture motherboard is measured, and the origin coordinate of the fixture motherboard is copied into the working coordinate system of the processing equipment. By setting the fixture motherboard, since the position of the fixture motherboard relative to the rotary table of the processing equipment is fixed, after the fixture holding the frame blank is set on the fixture motherboard, it can be processed without repeated positioning. In this way, the processing efficiency can be further improved.

[0048] In some embodiments, the tool of the processing equipment is assembled and pre-adjusted before it is put into use to ensure that the tool meets the processing requirements. Specifically, the necessary processing parameters of the tool such as tool compensation and tool offset are obtained. According to the standard life of the tool and the 24-hour processing time, sufficient tools are prepared in the tool magazine. At the same time, the length of the program is adjusted according to the actual processing time and standard life of the tool to ensure that the processing is completed within the tool life.

[0049] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
