Description

Technical Field

[0001] This utility model relates to the field of press equipment technology, and in particular to a copper sleeve guide rail temperature detection device. Background Technology

[0002] During the operation of presses (such as stamping presses, hydraulic presses, forging machines, etc.), the guiding system composed of the slide and guide rail is a key component to ensure the accuracy, stability, and lifespan of the equipment. Among them, the fit between the copper sleeve mounted on the slide and the fixed guide rail is particularly critical. A good fit ensures smooth, accurate, and low-frictional wear of the slide movement, while a poor fit (such as excessive tightness, lubrication failure, foreign object intrusion, or local deformation) will lead to increased friction, abnormal temperature rise, and thus accelerate the wear of the copper sleeve and guide rail, and even cause serious malfunctions such as equipment jamming and loss of accuracy, resulting in equipment downtime and economic losses.

[0003] Therefore, real-time monitoring of the mating area between the copper bushing and the guide rail, especially monitoring its frictional heating (manifested as abnormal temperature on the guide rail surface), is an important means of preventing equipment failure and performing predictive maintenance. Currently, the industry commonly uses handheld contact thermometers (such as spot temperature guns) or non-contact infrared thermometers, where operators manually measure the temperature point by point near the equipment guide rail when the equipment is stopped or running at low speed.

[0004] However, this traditional method of manual temperature measurement has significant drawbacks:

[0005] It is labor-intensive and inefficient: It requires operators to perform testing operations frequently, especially on large presses or multi-rail equipment, which is time-consuming and labor-intensive, and it is difficult to achieve high-frequency and full-coverage monitoring.

[0006] High safety risks: The working environment of the press is complex, and operators need to be close to the moving parts (even when the machine is stopped, there may be residual risks), which poses safety hazards.

[0007] Limited testing opportunities: Testing is usually conducted when the machine is stopped or at low speed, making it difficult to capture the true temperature rise of the equipment when it is running at full speed and full load, which is often the stage when friction problems are most likely to appear.

[0008] Insufficient detection coverage: Manual handheld temperature measurement can usually only measure a few discrete points on the guide rail surface, making it difficult to comprehensively and continuously reflect the temperature uniformity along the entire length of the guide rail, especially the circumferential cross-section. The temperature difference at different locations on the guide rail cross-section (such as the stress surface and non-stress surface) can be significant, and local abnormal high temperature points (hot spots) are easily missed.

[0009] Poor real-time performance: It cannot achieve continuous, real-time temperature monitoring, and it is difficult to detect instantaneous abnormal changes in temperature in a timely manner. Utility Model Content

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: See below Figures 1-4 .

[0030] A copper sleeve guide rail temperature detection device includes a slider 1, a guide rail 2, and a copper sleeve 3 disposed inside the slider 1. The copper sleeve 3 is fitted with the surface of the guide rail 2. The slider 1 is slidably connected to the guide rail 2 through the copper sleeve 3. The guide rail 2 is preferably a circular guide rail. The copper sleeve 3 is embedded in the mounting hole of the slider 1. When the copper sleeve 3 slides relative to the guide rail 2, heat can be generated on the surface of the guide rail 2. When the heat reaches a certain value, the sliding between the guide rail 2 and the copper sleeve 3 at that point on the surface becomes relatively unsmooth or has a high friction point.

[0031] To achieve real-time detection of the surface temperature of the guide rail 2, this embodiment has a temperature measuring unit 101 rotatably mounted on the slider 1, which can rise and fall with the slider 1 and detect the surface temperature of the guide rail 2. The temperature measuring unit 101 is an infrared thermometer. The line connecting the temperature measuring point of the temperature measuring unit 101 and the surface of the guide rail 2 is perpendicular to the axis of the guide rail 2. That is, the distance between the temperature measuring point of the temperature measuring unit 101 and the surface of the guide rail 2 is always the same when the temperature measuring unit 101 rotates relative to the guide rail 2.

[0032] A rotating ring 102, coaxially aligned with the guide rail 2, is rotatably mounted on the slider 1. A rotating groove is provided on the upper surface of the slider 1, and the rotating ring 102 is rotatably positioned within this groove. The temperature measuring unit 101 is located on the upper surface of the rotating ring 102. Figure 1 As shown, the temperature measuring head of the temperature measuring unit 101 always faces one side of the guide rail 2 surface. When the rotating ring 102 rotates, it drives the temperature measuring unit 101 to rotate synchronously, so as to realize the temperature measurement of the entire cross section of the guide rail 2 surface. The temperature measuring unit 101 is connected to the PLC controller. The fit between the guide rail 2 surface and the copper sleeve 3 is judged by the temperature and temperature change fed back by the temperature measuring unit 101.

[0033] The outer edge of the rotating ring 102 is fixed with an integrally formed drive tooth 103. The slider 1 is provided with a gear 104 that meshes with the drive tooth 103. The slider 1 is provided with a servo motor 105 for driving the gear 104 to rotate. Specifically, the side wall of the slider 1 is recessed inward to form a mounting cavity 106 for mounting the servo motor 105. The body of the servo motor 105 is fixed in the mounting cavity 106, and its drive shaft 107 passes upward through the wall of the mounting cavity 106 and is fixedly connected to the gear 104. The servo motor 105 drives the gear 104 to rotate, thereby causing the rotating ring 102 to rotate relative to the axis of the guide rail 2.

[0034] The servo motor 105 is also connected to the PLC controller. The PLC controller controls the start and stop of the servo motor 105 to achieve full-section temperature measurement of the temperature measuring unit 101 relative to the guide rail 2.

[0035] The upper end face of the rotating ring 102 is provided with a lifting push rod 4 for installing the temperature measuring unit 101. Specifically, a positioning seat 5 is fixedly provided on the upper end face of the rotating ring 102. The positioning seat 5 is provided with a second positioning hole 501 that is rotatably connected to the lower end of the lifting push rod 4. The lifting push rod 4 and the second positioning hole 501 are connected by a pin. The positioning seat 5 is symmetrically provided with adjusting bolts 502 on both sides that cooperate with the lower end face of the lifting push rod 4. The working angle of the lifting push rod 4 can be adjusted by adjusting the adjusting bolts 502 and the lower end face of the lifting push rod 4. The upper end of the adjusting bolt 502 is provided with a spherical surface, which makes point contact with the lower end face of the lifting push rod 4. That is, the lower end face of the lifting push rod 4 is supported, adjusted and fixed by the point contact of the supporting spherical surfaces of the adjusting bolts 502 on both sides.

[0036] The lifting push rod 4 is a servo push rod, connected to a PLC controller. Its upper end is the push rod end, and a temperature measuring unit 101 is fixedly mounted on the end of the push rod end. Specifically, a fixing frame 401 is provided at the upper end of the lifting push rod 4. The main body of the fixing frame 401 is sleeved on the rod body of the push rod end of the lifting push rod 4, and clamping plates 402 are symmetrically arranged on both sides. The clamping plates 402 clamp the rod body of the push rod end to achieve axial positioning. The clamping plates 402 are metal elastic sheets, and their material can be manganese steel. The fixing frame 401 also has a fixed connection to the end of the lifting push rod 4. The fixing hole and the fixing frame 401 are fixedly connected to the push rod end of the lifting push rod 4 through the fixing hole. The connection method can be a pin snap-fit ​​or a threaded connection. The fixing frame 401 is provided with a first positioning hole 403 that cooperates with the temperature measuring unit 101. The temperature measuring unit 101 is fixedly connected to the first positioning hole 403 by thread, and a locking nut can be set on the temperature measuring unit 101. When the slider 1 slides down, the lifting push rod 4 can synchronously lift the temperature measuring unit 101 by adapting to the sliding speed of the slider 1, so that the temperature measuring point briefly stops at a certain guide rail 2 surface to improve the temperature measuring accuracy.

[0037] The method of using a copper bushing guide rail temperature detection device as described above:

[0038] S1: When slider 1 moves up and down along guide rail 2, the PLC starts the temperature measurement program;

[0039] S2: The lifting push rod 4 uses the PLC to control the speed of the adapter slider 1 to push the temperature measuring unit 101 in the opposite direction, so that the temperature measuring unit 101 briefly stops on the surface of a certain guide rail 2, thereby improving the temperature measurement accuracy at that point.

[0040] S3: When it is necessary to perform full-section temperature measurement on a certain section of the guide rail 2, the servo motor 105 drives the rotating ring 102 to rotate at a constant speed, and the infrared thermometer continuously collects the surface temperature data of the guide rail.

[0041] S4: Temperature data is transmitted to the monitoring system in real time. When the temperature exceeds the limit, an alarm can be triggered or further operations can be carried out by the operator through observation of the monitoring system.

[0042] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
