Description

Technical Field

[0001] The utility model relates to the field of spring processing equipment, in particular to a multifunctional mobile tool magazine for spring parts. Background Art

[0002] The spring coiling machine is a mechanical equipment for producing springs. The steel wire is fed from the wire rack, first straightened, then the wire is coiled and reduced in diameter, and finally cut by a cutter to complete the production of a spring.

[0003] Existing spring machines generally have spaced-apart cutters on the outer wall of the wire outlet hole (refer to Chinese patent CN202330233301.9), so as to meet different processing requirements of the spring parts and process the spring parts into a predetermined shape.

[0004] Of course, there are also structures that use different tools, such as Chinese patent CN201911063437.9, which includes a curling mechanism and a cutting mechanism, thereby realizing the processing of the wire by the tool, but the various tools are all in the same plane. For some special-shaped parts (in actual spring processing, they belong to the broad sense of spring parts, such as spring sheets, torsion springs and other structures), they need to be processed or limited at multiple positions to achieve their processing and forming.

[0005] Therefore, how to design a multi-tool structure that can achieve processing at different positions in the axial length direction is the key to the design. Utility Model Content

[0006] The main purpose of the utility model is to propose a multifunctional mobile tool magazine for spring parts, aiming to realize the switching of tools in different positions, and the number of tools is large, thereby improving the processing applicability, reducing the replacement time, and the tool switching efficiency is high, thereby improving the processing efficiency.

[0007] To achieve the above-mentioned purpose, the utility model proposes a multifunctional mobile tool magazine for spring parts, comprising:

[0008] A machine base, which is arranged on a spring device (wherein the machine base can be multi-axis movable, fixed or swingable, so as to meet different processing requirements, and the installation position of the spring device and the machine base can refer to Chinese appearance patent CN202230744419.3);

[0009] A driving device, wherein the driving device is arranged in the middle of the machine base, and two sides of the driving device extend out of two side walls of the machine base;

[0010] The knife seats are provided with two groups which are slidably mounted on both sides of the machine base, and the driving device can drive the two knife seats to move relative to each other;

[0011] The bottom wall of the tool holder and the side wall away from the machine base are respectively provided with a first tool position and a second tool position, wherein a plurality of the first tool positions and the second tool positions are provided and arranged at intervals, and the first tool positions and the second tool positions are used for installing tools.

[0012] In actual work, multiple first tool positions and second tool positions are set to achieve simultaneous installation of multiple tools, and two tool holders are provided, so the two groups of first tool positions and second tool positions can be improved according to actual processing requirements to meet different processing requirements, wherein the tools can be curling knives, cutting knives, shaping knives, limiting knives, etc. with different curling degrees, and different tools can be set at the first tool position at the same horizontal position or staggered at the first tool position and the second tool position of the same tool holder or respectively set at different tool holders, so the tool switching efficiency is higher and the axial length processing is met, and for different special-shaped parts, only the tool needs to be replaced;

[0013] At the same time, the switching of the two tool holders adopts the same driving device, which makes the overall structure of the tool magazine smaller (compact structure) and reduces the large volume occupied by the tool magazine. Therefore, it can be used to process smaller parts with higher processing accuracy. When the driving device is working, the two tool holders move to opposite positions, thereby realizing the switching of the tools (the switching position can be the middle position or the side position, preferably the middle position).

[0025] like Figures 1 to 7 As shown, a multifunctional mobile tool magazine for spring parts comprises:

[0026] A machine base 1, wherein the machine base 1 is arranged on a spring device (wherein the machine base 1 can be multi-axis movable, fixed, or swingable, so as to meet different processing requirements, wherein the installation position of the spring device and the machine base 1 can refer to Chinese appearance patent CN202230744419.3);

[0027] A driving device 2, wherein the driving device 2 is disposed in the middle of the machine base 1, and two sides of the driving device 2 extend out of two side walls of the machine base 1;

[0028] The knife seats 3 are provided with two groups which are slidably mounted on both sides of the machine base 1, and the driving device 2 can drive the two knife seats 3 to move relative to each other;

[0029] The bottom wall of the tool holder 3 and the side wall away from the machine base 1 are respectively provided with a first tool position 31 and a second tool position 32 . There are a plurality of the first tool positions 31 and the second tool positions 32 arranged at intervals. The first tool positions 31 and the second tool positions 32 are used to install the tool 30 .

[0030] In actual work, multiple first tool positions 31 and second tool positions 32 are set to achieve simultaneous installation of multiple tools 30, and the tool holder 3 is provided with two, so the two groups of first tool positions 31 and second tool positions 32 can be improved according to actual processing requirements to meet different processing requirements, wherein the tools 30 can be curling knives, cutting knives, shaping knives, limiting knives, etc. with different curling degrees, and different tools 30 can be set at the first tool position 31 at the same horizontal position or staggered at the first tool position 31 and the second tool position 32 of the same tool holder 3 or respectively set at different tool holders 3, so the switching efficiency of the tools 30 is higher and the axial length processing is met, and for different special-shaped parts, only the tools 30 need to be replaced;

[0031] At the same time, the switching of the two tool holders 3 adopts the same driving device 2, which makes the overall structure of the tool magazine smaller and reduces the large volume occupied by the tool magazine. Therefore, it can be used to process smaller parts with higher processing accuracy. When the driving device 2 is working, the two tool holders 3 move to opposite positions, thereby realizing the switching of the tool 30, wherein the switching position can be the middle position or the side position, preferably the middle position.

[0032] In an embodiment of the utility model, the two side walls of the machine base 1 are provided with inwardly recessed drive grooves 11, and the drive grooves 11 are distributed along the length direction of the machine base 1. The drive device 2 is arranged in the middle of the machine base 1 and extends into the drive grooves 11. The setting of the drive grooves 11 makes the overall structure of the mobile tool magazine more streamlined and more stable.

[0033] Specifically, the driving device 2 is a gear 21. A positioning slot 12 is provided in the middle of the base 1. The gear 21 is pivotally mounted in the positioning slot 12. Both sides of the gear 21 extend out of the positioning slot 12 and partially extend into the driving slot 11. The gear 21 is connected to a servo rotary motor 23.

[0034] The knife seat 3 is provided with a rack 22 extending into the driving groove 11, and the rack 22 is meshed with the gear 21.

[0035] When the gear 21 rotates, the two racks 22 move in opposite directions.

[0036] In the embodiment of the utility model, the gear 21 is a helical gear, and the rack 22 is a helical rack. Of course, spur gears can also be used, but helical gears have higher loads, better stability, and effectively reduce travel errors;

[0037] Helical gears are not completely spiral gears. It should be said that spiral gears are the meshing mode of two helical gears, which are distinguished by the different directions of their force transmission in space. Ordinary spur gears mesh simultaneously along the tooth width, thus generating impact vibration noise and unstable transmission. Helical cylindrical gear transmission is better than spur gears, and can be used for high speed and heavy load with a tight center distance. Helical gear reducer is a novel reduction transmission device. It adopts the advanced design concept of optimization and modular combination system, with small size, light weight, large torque transmission, smooth start, fine transmission ratio classification, and can be connected arbitrarily and selected in a variety of installation positions according to user requirements.

[0038] Specifically, the gear 21 is a pin gear, the outer peripheral wall of the pin gear is provided with spaced pins, and the rack 22 is provided with pin grooves 201 that match the pins. The pin structure can reduce the stroke error caused by gear meshing, but its rotation speed is lower than that of the helical gear, that is, the switching speed of the tool 30 is slower than that of the helical gear.

[0039] Of course, a double-screw pair structure can also be used to achieve the switching of the two tool holders 3, but its volume is large and the switching efficiency is slow.

[0040] In the embodiment of the utility model, the base 1 is in an "I" shape. The base 1 with this structure has a better supporting effect and is easier to install.

[0041] Specifically, the upper wall and the lower wall of the machine base 1 located at the driving groove 11 are respectively provided with guide grooves 41 , and the knife seat 3 is provided with a guide slide seat 42 matched with the guide groove 41 .

[0042] In the embodiment of the utility model, the guide groove 41 is an inclined guide groove (ie, the cross section of the guide groove is triangular); the guide groove is a cross roller linear guide rail 200 (eg Figure 6 As shown). The clamping and sliding of the tool holder 3 is realized, which effectively ensures the processing stability of the tool 30. In the actual processing of the tool 30, the contact with the steel bar will generate a predetermined stress. Therefore, the clamping and sliding structure can effectively reduce the stress deviation and improve the stability of high-speed processing (reduce the correction time).

[0043] Specifically, the machine base 1 is provided with a stepped groove 51 for installing the guide groove, and the tool holder 3 is provided with a positioning portion 52 extending toward the machine base 1 . The positioning portion is arranged opposite to the stepped groove 51 , thereby increasing the contact area between the tool holder 3 and the machine base 1 .

[0044] In the embodiment of the utility model, the first tool position 31 and the second tool position 32 have the same structure, including strip holes 61 arranged at intervals on the machine base 1 and positioning holes 62 arranged on both sides of the strip holes, which can be fixed by nuts and screws.

[0045] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
