DETAILED DESCRIPTION
[0024] The technical solutions of the present application will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative effort fall within the scope of the present application.
[0025] Referring to Figures 1-5 The present application provides a technical solution:
[0026] A double helix heater processing tool, comprising a support shaft 1, a first fixed block 2, a positioning plate 3, a fastener 4 and a positioning ring 5, one end of the support shaft 1 is fixedly connected with the first fixed block 2, the other end of the support shaft 1 is detachably provided with the positioning plate 3 and the fastener 4, the first fixed block 2 is provided with the positioning ring 5, the positioning plate 3 and the positioning ring 5 are clamped with the double helix heater 6, and the positioning plate 3 and the positioning ring 5 are coaxially arranged. Wherein, the support shaft 1 penetrates the whole tool, so that each component can be arranged and positioned along its axis. The first fixed block 2 provides a fixed support point for the tool, ensuring the stability of the whole tool structure. The fixed position on the support shaft 1 lays a foundation for the installation and positioning of the rear parts. The coaxial arrangement of the positioning ring 5 and the positioning plate 3 can accurately limit the position of the double helix heater 6, ensuring that the heater will not shift or shake during processing, thereby improving the precision and quality of processing. By tightening the fastener 4, appropriate pressure can be applied to ensure precise combination of the tool components. Two helical grooves are formed on the double helix heater 6, which helps to enhance its heat dissipation performance, increase the heat exchange area with the surrounding environment, and avoid overheating damage. On the other hand, it is beneficial to improve the uniformity of heating, so that heat can be more evenly transmitted and distributed. The positioning plate 3 is clamped on the double helix heater 6 by the fastener 4.
[0027] In some embodiments, a detachable second fixed block 7 is arranged between the positioning plate 3 and the fastener 4, and the second fixed block 7 is sleeved on the support shaft 1. Wherein, the second fixed block 7 provides a pressing force to the positioning plate 3, reducing the friction of the fastener 4 to the positioning plate 3. The second fixed block 7 is coaxially arranged with the first fixed block 2.
[0028] In some embodiments, a step 8 is arranged on the first fixed block 2, and the positioning ring 5 is arranged on the step 8. Wherein, the step 8 provides a support platform for the positioning ring 5.
[0029] In some embodiments, the positioning ring 5 is provided with a first positioning step 9, and the positioning plate 3 is provided with a second positioning step 10, and the outer walls of the first and second positioning steps 9 and 10 are matched with the inner walls at both ends of the double-helix heater 6. The first and second positioning steps 9 and 10 work together to accurately position the other end of the double-helix heater 6, ensuring that both ends of the double-helix heater 6 can be accurately fixed. This ensures that the double-helix heater 6 maintains the correct position and posture during processing, and does not sway or displace left and right, thereby improving the accuracy and precision of processing.
[0030] In some embodiments, the positioning ring 5 is provided with a half-open slot 11, which is matched with one end of the positioning block 12, and the other end of the positioning block 12 is matched with the positioning slot on the double-helix heater 6. The half-open slot 11 provides space for the installation of the positioning block 12, so that the double-helix heater 6 can be effectively fixed in the axial and radial directions. The positioning block 12 enhances the fixing effect of the double-helix heater 6, improving the stability of processing. Further positioning of the double-helix heater 6 in the half-open slot 11 prevents it from swaying during processing.
[0031] In some embodiments, two half-open slots 11 are symmetrically arranged on the positioning ring 5. The symmetrical arrangement makes the clamping of the double-helix heater 6 more balanced and stable, ensuring that the double-helix heater 6 is uniformly stressed in the tooling, reducing deformation or positional deviation caused by uneven stress, and improving processing accuracy.
[0032] In some embodiments, the first fixing block 2 and the positioning ring 5 are both provided with a pin hole 13, and the two pin holes 13 are fixed by a positioning pin 14. The positioning pin 14 passes through the pin hole 13 to greatly improve the stability and positioning accuracy of the connection between the two. This ensures that the relevant components do not loosen or displace relative to each other during processing, ensuring consistency and accuracy of processing.
[0033] In some embodiments, one end of the support shaft 1 is provided with an external thread 15, which is matched with the internal thread of the fastener 4. The matching design of the external thread 15 and the internal thread of the fastener 4 facilitates the compression and fixation of the tooling components, and the adjustment operation is convenient. Moreover, the fastener is a nut.
[0034] In some embodiments, the fastener 4 is provided with a blind hole 16. The blind hole 16 can reduce the weight of the fastener 4, and the fastener 4 can also be tightened with the help of a steel rod or other tools.
[0035] Principle: Because the length of the spiral heating barrel is suspended for a long time, normal clamping cannot guarantee the accuracy and quality of the end, and positioning and clamping of the tool are required to ensure that the front and rear jump tolerances meet the tolerance quality required by the drawing. Hoisting is mainly through tool hoisting to avoid affecting the workpiece. The bolt heater blank can be firmly fixed on the tool to improve the processing efficiency and quality.
