Description

Technical Field

[0001] This invention belongs to the technical field of ball bearing slide rail testing devices, and particularly relates to a ball bearing slide rail raceway testing machine. Background Technology

[0002] The core of the lateral sliding force detection of the ball bearing slide rail is to measure the lateral constraint force of the track on the ball bearings, or the lateral impact force of the ball bearings on the track, during the reciprocating motion of the slide rail.

[0003] Currently, the side sliding force detection of ball bearing slide rails is performed on a single slide rail, resulting in low detection efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a ball bearing slide rail raceway testing machine in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a ball bearing slide rail raceway testing machine, comprising: Machine body; The positioning frame is fixedly connected to the table surface of the machine body; The track positioning plate is attached to the table surface of the machine body and snapped into the positioning frame. The track positioning plate has multiple positioning grooves arranged along a straight line. A force detection mechanism is located above the track positioning plate; A horizontal motion mechanism is fixedly connected to the machine body and is located above the track positioning plate. The horizontal motion mechanism is connected to and drives the force detection mechanism.

[0006] As a further description of the above technical solution: The force detection mechanism includes a horizontal plate, multiple vertical telescopic members, and multiple positioning pins. The horizontal plate is located above the track positioning plate and is connected to the horizontal movement mechanism. The multiple vertical telescopic members are fixedly connected to the horizontal plate in a straight line. Each vertical telescopic member corresponds to a positioning groove. The positioning pins are connected to the ends of the vertical telescopic members through multi-dimensional force sensors.

[0007] As a further description of the above technical solution: The horizontal plate is equipped with multiple indicator lights, each of which corresponds to a vertical telescopic device, and the indicator lights are electrically connected to the multi-dimensional force sensor via a controller.

[0008] As a further description of the above technical solution: The horizontal motion mechanism includes two support plates, multiple guide rods, a rotary motor, and a lead screw. The two support plates are fixedly connected to the table surface of the machine body. The two ends of the guide rods are fixedly connected to the two support plates. The two ends of the lead screw are connected to the two support plates through bearing seats. The lead screw is screwed to the horizontal plate. The rotary motor is fixedly connected to either of the support plates and is connected to and drives the lead screw.

[0009] As a further description of the above technical solution: The multiple guide rods and the multiple positioning slots are all parallel to the lead screw.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, by placing multiple slide rails in the positioning groove of the track positioning plate and placing the track positioning plate as a whole into the positioning frame of the machine body, the force detection mechanism is simultaneously inserted into the inner track of the multiple slide rails. The horizontal movement mechanism drives the force detection mechanism to move horizontally, causing the inner track and outer track of the multiple slide rails to intersect. The force detection mechanism detects multiple slide rails at the same time, which greatly improves the detection efficiency of lateral sliding force.

[0011] 2. In this invention, the positioning pin is inserted into the opening of the inner track of the slide rail by extending the vertical telescopic device. Under the movement of the horizontal plate, the inner track and the outer track slide alternately, so that the multi-dimensional force sensor can detect the value of the lateral sliding force, making the detection operation simple and convenient.

[0012] 3. In this invention, the rotating motor drives the lead screw to rotate. Under the guidance of the guide rod and the screw connection between the lead screw and the horizontal plate, the horizontal plate slides stably, thereby driving the inner and outer tracks of the slide rail to move smoothly and alternately.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-4 This invention provides a technical solution: a ball bearing slide rail raceway testing machine, comprising: Machine body 1; Positioning frame 2 is fixedly connected to the table surface of the machine body 1; The track positioning plate 3 is attached to the table surface of the machine body 1 and inserted into the positioning frame 2. The track positioning plate 3 has multiple positioning grooves 4 arranged along a straight line. Force detection mechanism 5 is located above the track positioning plate 3; A horizontal motion mechanism 6 is fixedly connected to the machine body 1, and the horizontal motion mechanism 6 is located above the track positioning plate 3. The horizontal motion mechanism 6 is connected to and drives the force detection mechanism 5. The force detection mechanism 5 includes a horizontal plate 51, multiple vertical telescopic devices 52, and multiple positioning pins 53. The horizontal plate 51 is located above the track positioning plate 3 and connected to the horizontal movement mechanism 6. The multiple vertical telescopic devices 52 are fixedly connected to the horizontal plate 51 in a straight line. Each vertical telescopic device 52 corresponds to a positioning groove 4. The positioning pins 53 are connected to the ends of the vertical telescopic devices 52 through a multi-dimensional force sensor 7. When the vertical telescopic device 52 extends, it inserts the positioning pins 53 into the openings of the inner track of the slide rail. Under the movement of the horizontal plate 51, the inner track and the outer track slide alternately, thereby enabling the multi-dimensional force sensor 7 to detect the value of the lateral sliding force, making the detection operation simple and convenient. The horizontal plate 51 is provided with multiple indicator lights 8, each of which corresponds to one of the vertical telescopic device 52. The indicator lights 8 are electrically connected to the multi-dimensional force sensor 7 through the controller, so that it can be determined which multi-dimensional force sensor 7 has a value exceeding the preset value, and thus detect whether the lateral sliding force is qualified. The horizontal motion mechanism 6 includes two support plates 61, multiple guide rods 62, a rotary motor 63, and a lead screw 64. The two support plates 61 are fixedly connected to the table surface of the machine body 1. The two ends of the guide rods 62 are fixedly connected to the two support plates 61. The two ends of the lead screw 64 are connected to the two support plates 61 through bearing seats. The lead screw 64 is screwed to the horizontal plate 51. The rotary motor 63 is fixedly connected to any of the support plates 61 and is connected to and drives the lead screw 64. The rotation of the rotary motor 63 drives the lead screw 64 to rotate. Under the guidance of the guide rods 62 and the screwing action between the lead screw 64 and the horizontal plate 51, the horizontal plate 51 slides stably, thereby driving the inner and outer tracks of the slide rail to move smoothly and alternately. The multiple guide rods 62 and the multiple positioning grooves 4 are all parallel to the lead screw 64 to ensure the stable movement of the horizontal plate 51.

[0020] Working principle: By placing multiple slide rails in the positioning grooves 4 of the track positioning plate 3, and placing the track positioning plate 3 as a whole into the positioning frame 2 of the machine body 1, the force detection mechanism 5 is simultaneously inserted into the inner track of the multiple slide rails. The horizontal movement mechanism 6 drives the force detection mechanism 5 to move horizontally, causing the inner and outer tracks of the multiple slide rails to intersect. The force detection mechanism 5 simultaneously detects multiple slide rails, greatly improving the detection efficiency of lateral sliding force. Specifically, the vertical telescopic device 52 extends to insert the positioning pin 53 into the opening of the inner track of the slide rail. Under the guidance of the guide rod 62 and the screw connection between the lead screw 64 and the horizontal plate 51, the horizontal plate 51 slides stably, thereby driving the inner and outer tracks of the slide rail to move smoothly and intersect. Under the movement of the horizontal plate 51, the inner and outer tracks slide intersect, allowing the multi-dimensional force sensor 7 to detect the value of the lateral sliding force. It can then determine which multi-dimensional force sensor 7 value exceeds the preset value, thereby detecting whether the lateral sliding force is qualified.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
