Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a sliding bracket, in particular to a motor sliding bracket. Background Art

[0002] At present, the power source of the linear slide is generally an electric motor, and the motor is directly installed on the guide rail of the linear slide. This installation method is like a new type of linear driver disclosed in the China Patent Library (application number: 201320348310.3), which includes an aluminum profile guide rail, a screw, a bell, a screw positioning piece, a large plastic cover and a motor. The screw positioning piece is fixed to one end of the aluminum profile guide rail by screws, and the bell slides back and forth along the aluminum profile guide rail. The large plastic cover is fixed to the other end of the aluminum profile guide rail by two screws, and two waist-round holes are also provided on its side.

[0003] As can be seen from the above driver drawings, the motor is vertically arranged and is clamped and positioned on the aluminum profile rail by means of an upper cover and a lower cover, but this positioning method is only applicable to vertically arranged motors. Utility Model Content

[0004] The utility model aims to solve the above problems in the prior art and proposes a motor sliding bracket which can adapt to the adjustment position of a horizontally arranged motor.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a motor sliding bracket, which is arranged on an aluminum profile, and slide grooves are provided on both sides of the width of the aluminum profile, and the slide groove is composed of two side walls arranged oppositely and a bottom wall located between the two side walls, characterized in that the sliding bracket includes an annular flange, and the axial direction of the annular flange is parallel to the length direction of the aluminum profile; two pressure plates are formed on the annular flange, and the two pressure plates are respectively pressed against the two sides of the width of the aluminum profile; rolling members with outer walls as circumferential surfaces are provided in the two slide grooves, the axes of the rolling members extend along the width direction of the aluminum profile, and the two side walls of the slide groove are in contact with the outer sides of the corresponding rolling members; the rolling members are rotatably arranged on the corresponding pressure plates, and the pressure plates are also provided with threaded holes arranged through the width direction of the aluminum profile, the two threaded holes are respectively arranged opposite to the two slide grooves, bolts are screwed in the threaded holes, and the bolt rods can be tightly pressed on the corresponding bottom walls of the slide grooves.

[0006] When in use, the motor is fixedly connected to the bracket by using the annular flange and screws; then the bracket is slid along the axial direction of the aluminum profile to a set position, and finally the bolts are tightened to position the bracket and the motor as a whole.

[0007] When the sliding bracket is in use, the motor position can be adjusted by simply turning the bolt and sliding the bracket. The entire process not only has fewer steps, but also the cooperation of the rolling element and the pressure plate makes the bracket slide more steadily and smoothly, thereby greatly enhancing the convenience of adjusting the motor position.

[0008] In the above motor sliding bracket, the above rolling element is a bearing, the inner ring of the bearing is fixedly connected to the corresponding pressure plate, and the outer ring of the bearing is pressed on the two side walls of the corresponding slide groove. The above design has the advantages of simple structure and stable operation.

[0009] In the above motor sliding bracket, a positioning column is formed on the pressure plate, the positioning column and the bearing are coaxially arranged, and the inner ring of the bearing is sleeved and fixed on the positioning column. The design of the positioning column facilitates the installation and positioning of the bearing.

[0010] In the above-mentioned motor sliding bracket, an annular shaft shoulder surface is formed on the outer wall of the positioning column, and a coaxial and annular stopper is fixed on the positioning column. The stopper is located between the corresponding annular shaft shoulder surface and the corresponding bottom wall of the slide groove, and the two ends of the inner ring of the bearing are respectively pressed against the corresponding annular shaft shoulder surface and the corresponding stopper. With the cooperation of the annular shaft shoulder surface and the stopper, the bearing is effectively limited in the axial direction, ensuring that the bearing can be stably rolled to adjust the bracket position, further facilitating the motor position adjustment.

[0011] In the above-mentioned motor sliding bracket, an annular groove coaxial with the positioning column is also formed on the outer side wall of the positioning column, and the limiting member is a shaft retaining ring installed in the annular groove.

[0012] As another solution, in the above-mentioned motor sliding bracket, the limiting member is a retaining ring sleeved and fixed on the positioning column.

[0013] In the above-mentioned motor sliding bracket, the positioning column is hollow, and the inner hole of the positioning column is part of the above-mentioned threaded hole, that is, the positioning column plays the role of supporting the bearing and the bolt at the same time. This not only reduces the length of the pressure plate, reduces material input, and reduces costs, but also makes the connection between the pressure plate and the aluminum profile more concentrated, thereby improving the motor positioning strength and stability.

[0014] In the above-mentioned motor sliding bracket, the annular flange and the pressure plate are an integrated structure and are formed by casting, so as to greatly enhance the structural strength of the bracket.

[0015] Compared with the prior art, the motor sliding bracket has the following advantages:

[0016] When the sliding bracket is in use, the motor position can be adjusted by simply turning the bolt and sliding the bracket. The entire process not only has fewer steps, but also the cooperation of the rolling element and the pressure plate makes the bracket slide more steadily and smoothly, thereby greatly enhancing the convenience of adjusting the motor position.

[0017] The positioning column plays the role of supporting the bearing and the bolt at the same time, which not only reduces the length of the pressure plate, reduces material input and reduces costs, but also makes the connection between the pressure plate and the aluminum profile more concentrated, thereby improving the positioning strength and stability of the motor.

[0022] 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.

[0023] Embodiment 1

[0024] like Figure 1 As shown, the motor sliding bracket is arranged on an aluminum profile 1, and a slide groove 1a is provided on both sides of the width of the aluminum profile 1. The length of the slide groove 1a extends along the length direction of the aluminum profile 1, and the slide groove 1a is composed of two side walls 1a1 arranged opposite to each other and a bottom wall 1a2 located between the two side walls 1a1.

[0025] Specifically,

[0026] The motor sliding bracket includes an annular flange 2, and the axial direction of the annular flange 2 is parallel to the length direction of the aluminum profile 1. Two pressing plates 2a are formed on the annular flange 2, and the two pressing plates 2a are arranged side by side along the width direction of the aluminum profile 1, and the two pressing plates 2a are pressed against the two sides of the width of the aluminum profile 1 respectively.

[0027] like Figure 1 and Figure 2 As shown, the two chute 1a are provided with rolling elements with outer side walls as circumferential surfaces, the axis of the rolling elements extends along the width direction of the aluminum profile 1, and the two side walls 1a1 of the chute 1a are in contact with the outer side walls of the corresponding rolling elements. The rolling elements are rotatably arranged on the corresponding pressing plate 2a, and the pressing plate 2a is also provided with threaded holes penetrating along the width direction of the aluminum profile 1, and the two threaded holes are respectively arranged opposite to the two chute 1a, and bolts 3 are screwed in the threaded holes, and the rod of the bolt 3 can be tightly pressed on the bottom wall 1a2 of the corresponding chute 1a.

[0028] When in use, the motor 6 is fixedly connected to the bracket by using the annular flange 2 and screws; then the bracket is slid axially along the aluminum profile 1 to a set position, and finally the bolts 3 are tightened to position the bracket and the motor 6 as a whole.

[0029] When the sliding bracket is in use, the position of the motor 6 can be adjusted by simply rotating the bolt 3 and sliding the bracket. The whole process not only has fewer steps, but also the cooperation of the rolling element and the pressure plate 2a makes the bracket slide more steadily and smoothly, thereby greatly enhancing the convenience of adjusting the position of the motor 6.

[0030] In this embodiment,

[0031] like Figure 2 and Figure 3 As shown, the rolling element is a bearing 4, and the bearing 4 is an existing ordinary ball bearing 4, and the bearing 4 includes an inner ring 4a and an outer ring. Among them, the inner ring 4a of the bearing 4 is fixedly connected to the corresponding pressure plate 2a, and the outer ring of the bearing 4 is pressed on the two side walls 1a1 of the corresponding slide 1a. Specifically, a positioning column 2b is formed on the pressure plate 2a, and the positioning column 2b and the bearing 4 are coaxially arranged, and the inner ring 4a of the bearing 4 is sleeved and fixed on the positioning column 2b. The design of the positioning column 2b facilitates the installation and positioning of the bearing 4. Further explanation, an annular shoulder surface 2b1 is formed on the outer wall of the positioning column 2b, and the annular shoulder surface 2b1 is coaxially arranged with the positioning column 2b. A limiting member 5 coaxial with the positioning column 2b and in an annular shape is also fixed on the positioning column 2b, and the limiting member 5 is located between the corresponding annular shoulder surface 2b1 and the bottom wall 1a2 of the corresponding slide 1a, and the two ends of the inner ring 4a of the bearing 4 are respectively pressed on the corresponding annular shoulder surface 2b1 and the corresponding limiting member 5. With the cooperation of the annular shoulder surface 2b1 and the limiting member 5, the bearing 4 is effectively limited in the axial direction, ensuring that the bearing 4 can roll stably to adjust the position of the bracket, further facilitating the position adjustment of the motor 6.

[0032] Among them, an annular groove coaxial with the positioning column 2b is also opened on the outer side wall of the positioning column 2b, and the limiting member 5 is a shaft retaining ring installed in the annular groove.

[0033] like Figure 2 and Figure 3 As shown, the positioning column 2b is hollow, and the inner hole of the positioning column 2b is part of the above-mentioned threaded hole, that is, the positioning column 2b plays the role of supporting the bearing 4 and the bolt 3 at the same time, which not only reduces the length of the pressure plate 2a, reduces material input, and reduces costs, but also makes the connection between the pressure plate 2a and the aluminum profile 1 more concentrated, thereby improving the positioning strength and stability of the motor 6.

[0034] In actual products, the annular flange 2 and the pressing plate 2a are an integrated structure and are formed by casting to greatly enhance the structural strength of the bracket.
