Description

Technical Field

[0001] The utility model relates to the technical field of antenna cover manufacturing, in particular to an automatic antenna cover cutting machine. Background Art

[0002] The radome is a structure that protects the antenna system from the external environment. It has good electromagnetic wave penetration characteristics in electrical performance and can withstand the harsh external environment in mechanical performance. Outdoor antennas are usually placed in the open air and are directly attacked by storms, snow, dust and solar radiation in nature, which causes the antenna to have reduced accuracy, shortened life and poor working reliability. The radome is generally made of a larger overall material cut into small pieces.

[0003] At present, a Chinese patent with announcement number CN213614639U discloses a wire cutting device for the production of an antenna cover assembly station, including a bracket, two groups of rollers are arranged at intervals in the bracket, a cavity is formed between the two groups of rollers, the antenna cover is supported between the two groups of rollers, and the cutting is completed at the cavity. Specifically, a lead screw reciprocating device is provided at the cavity, and the device includes two groups of lead screws opposed to each other up and down, and an electrode wire is connected between the nuts of the two lead screws. During cutting, the two lead screws rotate synchronously to make the two nuts move at the same time, thereby driving the electrode wire to pass through the antenna cover to complete the cutting. However, the simultaneous movement of the two nuts places high demands on the matching accuracy between the two lead screws, which will lead to unsmooth cutting and affect the cutting accuracy.

DETAILED DESCRIPTION

[0018] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0019] like Figure 1 , Figure 2 , Figure 3 As shown, an automatic radome cutting machine comprises two sets of rollers 1 arranged at intervals, a cutting space 2 is formed between the two sets of rollers 1, and a cutting device is arranged at the cutting space 2. During cutting, the radome to be cut is transferred and supported between the two sets of rollers 1, and then the cutting device can cut the radome at the cutting space 2.

[0020] Specifically, the cutting device includes a support member 3, a swing member 4, and a cutting piece connected between the support member 3 and the swing member 4. More specifically, the swing member 4 is adapted to be able to swing the cutting piece with the support member 3 as a fulcrum, and then the cutting piece can cut off the antenna cover in a swinging posture.

[0021] In some embodiments, the cutting device further comprises a connecting frame 5, and the supporting member 3 and the swinging member 4 are respectively arranged on both sides of the connecting frame 5, and respectively comprise a rotating seat 6 and an arc guide rail 7. The two sides of the connecting frame 5 refer to the positions arranged on both sides of the antenna cover to be cut, and one end of the cutting piece is rotatably supported on the rotating seat 6, and the other end is movably adapted on the arc guide rail 7. Therefore, as one end of the cutting piece is transferred on the arc guide rail 7, the cutting piece will swing with the rotating seat 6 as the fulcrum, thereby realizing the cutting of the antenna cover.

[0022] For example, a sliding seat 8 is slidably adapted on the arc-shaped guide rail 7 , an end of the cutting piece is arranged on the sliding seat 8 , and a driving mechanism 9 for driving the sliding seat 8 to slide along the arc-shaped guide rail 7 is also arranged on the arc-shaped guide rail 7 .

[0023] like Figure 2 As shown, in one example, an arc-shaped rack 10 is provided on the arc-shaped guide rail 7, and the driving mechanism 9 includes a driving gear 11 rotatably provided on the sliding seat 8, the driving gear 11 is meshed with the arc-shaped rack 10, and the sliding seat 8 is also provided with a motor for driving the driving gear 11 to rotate. It can be understood that as the motor drives the driving gear 11 to rotate, the sliding seat 8 will move along the arc-shaped guide rail 7 under the cooperation of the driving gear 11 and the arc-shaped rack 10, thereby realizing the above-mentioned swinging action of the cutting piece. Obviously, the reciprocating swing of the cutting piece can be realized by the forward and reverse rotation of the motor. In order to improve the accuracy, the motor can preferably be a servo motor.

[0024] like Figure 3 As shown, in another example, an arc guide groove is provided on the arc guide rail 7, and the sliding seat 8 is slidably adapted in the arc guide groove, and a spring 12 is also provided in the arc guide groove, and the spring 12 applies an elastic force to the sliding seat 8 to drive it to be in the end of the arc guide groove without being acted upon by external forces. The driving mechanism 9 includes a cable 13 connected to the sliding seat 8 and a winding mechanism 14 for driving the cable 13 to be wound up. It can be understood that as the winding mechanism 14 winds up the cable 13, the sliding seat 8 will gradually overcome the elastic force of the spring 12 and slide along the arc guide groove, thereby realizing the swing of the cutting piece; and as the winding mechanism 14 unfolds the cable 13, the sliding seat 8 will swing back to the initial position under the elastic force of the spring 12. Therefore, through the different winding actions of the winding mechanism 14 on the cable 13, the cutting piece can also undergo the expected reciprocating swing.

[0025] As a preferred example of a cutting member, the cutting member may include an electrode wire 15, and a conductive seat of the electrode wire 15 is rotatably supported on a rotating seat 6, and a discharge head of the electrode wire 15 is movably adapted on the arc guide rail 7, that is, the discharge head of the electrode wire 15 is installed on a sliding seat 8. When the electrode wire 15 swings, the electrode wire 15 gradually discharges and passes through the antenna cover to complete the cutting action.

[0026] As another solution, the cutting member may include a reciprocating saw 16, and a guide seat 17 is also slidably adapted on the sliding seat 8. The reciprocating saw 16 is a prior art and will not be described in detail in this disclosure. Specifically, the housing of the reciprocating saw 16 is rotatably supported on the rotating seat 6, and the end of the saw blade of the reciprocating saw 16 is connected to the guide seat 17. When the reciprocating saw 16 swings, the power mechanism of the reciprocating saw 16 will drive the saw blade to reciprocate to achieve cutting of the antenna cover, during which the guide seat 17 will slide accordingly in the sliding seat 8 so as not to affect the normal operation of the saw blade.

[0027] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
