Technical Field
[0001] The utility model belongs to the technical field of sewing equipment and relates to an adjustable mounting bracket and a mounting structure of a non-contact encoder. Background Art
[0002] In industrial sewing equipment, in order to better improve work efficiency, it is necessary to obtain information such as the rotation angle, frequency and speed of the spindle when the sewing machine is working. In the prior art, the encoder and the spindle are directly connected together, which will cause the encoder to slip and wear.
[0003] Based on the above situation, there is currently a non-contact encoder that uses the principle of Hall induction and adds a pair of pole magnets to the main shaft of the equipment. When the main shaft rotates, the non-contact encoder can sense the change in the magnetic field and convert it into an ABZ incremental encoder signal. However, this design of using a non-contact encoder to monitor the rotation parameters of the main shaft requires very high installation accuracy of the encoder, which makes the encoder very troublesome to install. It is difficult to fine-tune the position of the encoder during the installation process, making it difficult to accurately align the encoder with the magnet on the main shaft. Utility Model Content

[0005] The purpose of the utility model can be achieved through the following technical solutions: an adjustable mounting bracket, comprising:
[0006] Base rod;
[0007] A first adjustment seat, the first adjustment seat is mounted on the base rod, and the first adjustment seat has a first fixed state and a first free state; when the first adjustment seat is in the first fixed state, the first adjustment seat is fixed relative to the base rod; when the first adjustment seat is in the first free state, the first adjustment seat is allowed to rotate with the base rod as the rotation center and is allowed to move along the axial direction of the base rod;
[0008] A second adjustment seat, the second adjustment seat is connected to the first adjustment seat, the second adjustment seat has a second fixed state and a second free state; when the second adjustment seat is in the second fixed state, the second adjustment seat is fixed relative to the first adjustment seat; when the second adjustment seat is in the second free state, the second adjustment seat is allowed to move relative to the first adjustment seat.
[0009] Preferably, the first adjustment seat is configured as a clamping element, the clamping element has a C-shaped clamping opening, the base rod is passed through the C-shaped clamping opening, and the clamping element is connected with a first bolt for adjusting the tightening degree of the C-shaped clamping opening.

[0011] Preferably, the base rod has a threaded connection section.
[0012] Preferably, when the second adjustment seat is in the second free state, the direction in which the second adjustment seat is allowed to move is perpendicular to the axial direction of the base rod.
[0013] A mounting structure for a non-contact encoder is also proposed, comprising the adjustable mounting bracket and a non-contact encoder, wherein the non-contact encoder is fixedly connected to a second adjustment seat; when the first adjustment seat is in a first free state and the second adjustment seat is in a second free state, the non-contact encoder is allowed to move axially and radially along the base rod and rotate around the base rod.

[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0024] like Figure 1-3 As shown, an adjustable mounting bracket includes: a base rod 100; a first adjustment seat 200, the first adjustment seat 200 is installed on the base rod 100, and the first adjustment seat 200 has a first fixed state and a first free state; when the first adjustment seat 200 is in the first fixed state, the first adjustment seat 200 is fixed relative to the base rod 100; when the first adjustment seat 200 is in the first free state, the first adjustment seat 200 is allowed to rotate with the base rod 100 as the rotation center and is allowed to move along the axial direction of the base rod 100; a second adjustment seat 300, the second adjustment seat 300 is connected to the first adjustment seat 200, and the second adjustment seat 300 has a second fixed state and a second free state; when the second adjustment seat 300 is in the second fixed state, the second adjustment seat 300 is fixed relative to the first adjustment seat 200; when the second adjustment seat 300 is in the second free state, the second adjustment seat 300 is allowed to move relative to the first adjustment seat 200.
[0025] This mounting bracket is used to install the non-contact encoder 400, and is intended to solve the problems of difficult installation and positioning accuracy of the non-contact encoder 400 in industrial sewing equipment. The base rod 100 is the basic supporting component of the entire bracket, connected and fixed to the frame or other fixed points. The first adjustment seat 200 is installed on the base rod 100. In the fixed state, it is firmly connected to the base rod 100 and remains stable and motionless; when switched to the free state, it can not only rotate freely around the center of the base rod 100, but also slide axially, providing flexibility for subsequent adjustments. The second adjustment seat 300 is connected to the first adjustment seat 200, and also has two states: fixed and free. When it is in a fixed state, it is fixed with the first adjustment seat 200; after entering the free state, it can move relative to the first adjustment seat 200, increasing the dimension of adjustment.
[0026] This bracket is particularly suitable for the installation of a non-contact encoder 400, which is fixed on the second adjustment seat 300. When the first adjustment seat 200 is in a free state and the second adjustment seat 300 is also in a free state, the encoder can move along the axial direction and radial direction of the base rod 100 and rotate around the base rod 100, so as to accurately align the magnet 500 on the spindle.
[0027] It is important to note that a certain gap needs to be maintained between the non-contact encoder and the spindle magnet 500. This gap must be within a certain range and cannot be too large, otherwise the non-contact encoder will not be able to sense the magnetic field. This gap is actually determined by the axial position of the first adjustment seat 200 on the base rod 100, that is, the gap between the non-contact encoder and the magnet 500 can be adjusted by axially moving the first adjustment seat 200 on the base rod 100. The offset distance between the non-contact encoder and the center of the spindle magnet 500 also needs to be within the allowable range. It is best to allow the non-contact encoder to be completely aligned with the center of the spindle magnet 500. This offset distance is actually determined by the position of the second adjustment seat 300 relative to the first adjustment seat 200 and the angle of the first adjustment seat 200 relative to the base rod 100. That is, the position of the non-contact encoder relative to the spindle magnet 500 can be adjusted by moving the second adjustment seat 300 relative to the first adjustment seat 200 and rotating the first adjustment seat 200 relative to the base rod 100.
[0028] like Figure 1-3 As shown, on the basis of the above embodiment, the first adjustment seat 200 is configured as a clamping element, the clamping element has a C-shaped clamping opening 210, the base rod 100 is passed through the C-shaped clamping opening 210, and the clamping element is connected with a first bolt for adjusting the tightening degree of the C-shaped clamping opening 210. The tightening degree of the first bolt determines whether the clamping element is in the first fixed state or the first free state.
[0029] The first adjustment seat 200 is designed as a clamping element, which is actually an existing element, and has a C-shaped clamping opening. The first bolt passes through the opening of the C-shaped clamping opening 210. The opening and closing of the C-shaped clamping opening 210 can be controlled by the first bolt connected to the clamping element, and the rotation of the bolt directly affects the clamping degree of the C-shaped clamping opening 210. In the actual structure, the base rod 100 is inserted into the C-shaped clamping opening 210. Loosening the first bolt can allow the C-shaped clamping opening 210 to open so that the clamping element is in the first free state, and tightening the first bolt can tighten the C-shaped clamping opening 210 so that the clamping element is in the first fixed state.
[0030] like Figure 1-3 As shown, on the basis of the above embodiment, the second adjustment seat 300 is provided with a waist-shaped hole 310 , and the second bolt passes through the waist-shaped hole 310 to be connected with the first adjustment seat 200 .
[0031] The second adjustment seat 300 is provided with a waist-shaped hole 310, the characteristic of which is that its shape allows the second bolt to be deflected or moved within a certain range while maintaining the stability of the connection. The relative position between the second adjustment seat 300 and the first adjustment seat 200 can be adjusted in the second free state.
[0032] When adjustment is required, the second bolt is loosened, and the second adjustment seat 300 can move relative to the first adjustment seat 200 along the path of the waist-shaped hole 310. When fixation is required, the second adjustment seat 300 can be set in the second fixed state by tightening the second bolt, and the relative fixation between the second adjustment seat 300 and the first adjustment seat 200 remains unchanged, thereby ensuring the stability and reliability of the entire bracket system after the position is determined.
[0033] Preferably, when the second adjustment seat 300 is in the second free state, the direction in which the second adjustment seat 300 is allowed to move is perpendicular to the axial direction of the base rod 100 .
[0034] like Figure 1 As shown, on the basis of the above embodiment, the base rod 100 has a threaded connection section 110. The threaded connection section 110 is used to connect with the threaded hole on the frame. By screwing the threaded connection section 110 into the pre-prepared threaded hole or the matching nut, the base rod 100 can be quickly and accurately installed and fixed.
[0035] like Figure 1-3As shown, based on the above-mentioned embodiment, a mounting structure of a non-contact encoder is also proposed, including an adjustable mounting bracket and a non-contact encoder 400, and the non-contact encoder 400 is fixedly connected to the second adjustment seat 300; when the first adjustment seat 200 is in a first free state and the second adjustment seat 300 is in a second free state, the non-contact encoder 400 is allowed to move axially and radially along the base rod 100 and rotate around the base rod 100.
[0036] This installation structure provides three-dimensional adjustment capability for the positioning installation of the non-contact encoder 400. This structure allows the non-contact encoder 400 to not only move in the axial direction of the base rod 100, that is, to adjust along the axial direction of the base rod 100, but also to fine-tune in the radial direction of the base rod 100, and to rotate around the base rod 100 to ensure that the non-contact encoder 400 is aligned with the magnet 500 on the spindle. This ensures that the non-contact encoder 400 can more accurately sense the magnetic field changes of the spindle.
[0037] On the basis of the above embodiment, a frame is further included, and the base rod 100 is fixedly connected to the frame. The frame provides a solid installation base for the mounting bracket of the non-contact encoder 400, and the frame mainly serves as a supporting structure for the base rod 100. In the actual structure, the frame is provided with a threaded hole, and the threaded connection section 110 of the base rod 100 is connected to the threaded hole, so that the base rod 100 and the frame are fixed together.

If the specific posture changes, the directional indication will also change accordingly.
[0039] In addition, in the present invention, the descriptions of "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0041] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
