Description

Technical Field

[0001] This invention relates to the field of mechanical engineering technology, and particularly to the cross-application of tooling design and force detection. It is especially suitable for scenarios such as component assembly, thrust performance testing of mechanical components, or equipment assembly force monitoring in industrial production. It is a special tooling for achieving accurate thrust detection based on pressure sensors. Background Technology

[0002] In production processes such as mechanical manufacturing, parts assembly, or product performance testing, thrust parameters are key quality indicators for measuring assembly accuracy, structural stability, and product reliability. In processes such as bearing press-fitting, gear meshing assembly, and fastener locking, the magnitude of the applied thrust must be strictly controlled. Insufficient thrust may lead to loosening of parts and transmission failure; excessive thrust may cause deformation and damage to parts, directly affecting the consistency and reliability of product quality.

[0003] Under current conditions, there are no relevant technical means to detect the magnitude of thrust, and there is an urgent need for a dedicated thrust detection tool to solve the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to provide a tooling for thrust detection using a pressure sensor, which solves the technical problem that current thrust parameter detection in scenarios such as component assembly cannot achieve quantitative data acquisition.

[0005] To address the aforementioned technical problems, this invention provides a tooling for thrust detection using a pressure sensor, comprising a base mounted on a base plate and a magnetic powder brake, the magnetic powder brake being located on one side of the base; a linear guide rail is provided on the base, and a slider is slidably connected to the linear guide rail; a sliding block is connected to the slider, and a rack is provided on the sliding block; bearing seats connected to the base are provided on both sides of the linear guide rail, and a drive shaft is rotatably connected between the bearing seats via bearings; a gear is fixed on the drive shaft, and the gear meshes with the rack; a pressure sensor is connected to the end face of the rack, and one end of the drive shaft is connected to the magnetic powder brake via a coupling; During operation, the test product applies a thrust to the rack, driving the sliding block and rack to move along the linear guide rail. The rack drives the gear and transmission shaft to rotate. The magnetic powder brake applies a braking torque to the transmission shaft in the opposite direction of rotation. By detecting the signal from the pressure sensor and combining the braking torque value provided by the magnetic powder brake with the lever arm determined by the pitch circle radius of the gear, the output thrust value of the test product is calculated and quantified based on the relationship between the thrust and the torque.

[0006] The sliding block is fixed on the slider so that the sliding block can reciprocate on the linear guide rail.

[0007] The gear rotates on the bearing housing via a drive shaft.

[0008] The maximum reciprocating stroke of the sliding block on the linear guide rail is 200mm.

[0009] The formula for calculating the thrust value is: Thrust = Braking torque / lever arm, where the lever arm is the pitch circle radius of the gear.

[0010] The thrust detection range of the tooling is 0N~6600N.

[0011] The pressure sensor is used to collect the pressure signal on the rack in real time and transmit it to the display or processing device to realize the real-time display and recording of the thrust value.

[0012] Compared with existing technologies, this invention integrates a pressure sensor to collect the pressure signal applied by the thrust in real time. At the same time, it establishes a quantitative correlation model of "thrust-torque" using a specified stroke distance, so as to indirectly and accurately obtain the corresponding thrust value by detecting the torque. This can effectively improve the effectiveness of detection technology in the field of thrust detection, optimize the effective quantitative detection technology of thrust parameters, and has a thrust detection range of 0N to 6600N, thus effectively solving the current technical problems of thrust detection.

[0013] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, and in order to make the above and other objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention are described below.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this invention clearer, the embodiments of this invention will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details are presented in the embodiments of this invention to facilitate a better understanding of this application. However, the technical solutions claimed in this application can be implemented even without these technical details and various variations and modifications based on the following embodiments. The division of the following embodiments is for ease of description and should not constitute any limitation on the specific implementation of this invention. The embodiments can be combined with and referenced by each other without contradiction.

[0017] like Figure 1 As shown, the linear guide rail 4 is fixed on the base 2, the pressure sensor 8 is fixed on the end face of the rack 7, the rack 7 is fixed on the sliding seat 6, the sliding seat 6 is fixed on the slider 3 and can reciprocate on the linear guide rail 4 (maximum stroke 200mm); the gear 9 is fixed on the drive shaft 10 and rotates on the bearing seat 5 through the bearing, and the drive shaft 10 is connected to the magnetic powder brake 13 through the coupling 12.

[0018] When the test product 11 outputs thrust, it drives the rack 7 to move linearly. The rack 7 drives the gear 9 to rotate (the 1 / 2 pitch circle of the gear 9 is the lever arm). The magnetic powder brake 13 provides braking torque in the opposite direction to the pressure applied by the test product 11. The magnitude of the thrust can be measured by the formula "thrust = torque / lever arm" using the torque value provided by the magnetic powder brake 13 and the pitch circle size of the gear 9. Finally, the pressure sensor 8 collects the pressure signal received by the rack 9 in real time and transmits it to the display or processing device to realize the real-time display and recording of the thrust value.

[0019] In summary, the present invention can realize thrust value detection and quantitative display of thrust results.

[0020] Those skilled in the art will understand that the above embodiments can be modified in form and detail in practical applications without departing from the spirit and scope of the invention.
