Description

Technical Field

[0001] This utility model relates to a measuring device, and more particularly to a metal rod bending measurement device, belonging to the field of metal rod processing technology. Background Technology

[0002] Bending degree refers to the degree of bending of long rolled products (sections, bars, tubes) in the length direction. The bending degree per meter is the chord height of bending per meter. The ratio of the total chord height of bending to the total length is the total bending degree. In the production process of metal bars, bending needs to be measured to prevent defective metal bars from being produced.

[0003] The "Metal Rod Bending Measurement Device" disclosed in application number "202221943739.2" includes "a measuring rod disposed below the measuring device beam and a standard rod disposed below the measuring device beam; an adjustment frame disposed below the measuring device beam, and a guide rod and an adjustment rod disposed inside the adjustment frame." In this utility model, when measuring the bending of a metal rod, the metal rod is placed between two sets of clamping plates. By controlling the movement of the two sets of clamping plates towards the metal rod, the metal rod is clamped, and at the same time, the metal rod is moved towards the standard rod, so that the surface of the metal rod contacts the measuring device beam, thus avoiding the problem of different heights of the metal rod in the clamping device due to different diameters.

[0004] However, the above method has the following drawbacks: In the process of measuring the bending degree of a metal rod, the metal rod is moved along the direction of a standard rod, and the degree of bending is determined by using a measuring rod. However, in actual operation, using a clamping plate to synchronously drive the metal rod to move in the vertical direction is inconvenient, making it difficult to ensure the consistency and stability of the movement process, reducing the efficiency and accuracy of the metal rod bending degree measurement, and increasing the operational difficulty for the measuring personnel. Utility Model Content

[0005] The purpose of this invention is to provide a metal rod bending measurement device to solve the problem mentioned in the background art that the clamping plate drives the metal rod to move vertically inconveniently, affecting the consistency and stability of the movement.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a metal rod bending degree measuring device, comprising a base plate, a support at the middle of the top of the base plate, a horizontal plate above the support, two measuring gauges symmetrically arranged on the surface of the horizontal plate, a top column at the middle of the bottom of the horizontal plate, a lead screw rotatably arranged inside the support, both ends of the lead screw being threadedly connected to inclined blocks through lead screw nuts, and a limiting plate at the top of the inclined blocks, a clamping seat slidably arranged outside the limiting plate, a rod body placed on the top of the two clamping seats, and a moving component for moving the top column provided on one side of the top of the base plate.

[0007] As a preferred embodiment of this utility model, the surface of the base plate is provided with four evenly spaced mounting holes, and both sides of the support are provided with several evenly spaced triangular plates, with the bottom end of the triangular plates being fixedly connected to the top end of the base plate.

[0008] As a preferred embodiment of this utility model, the measuring rod of the measuring instrument penetrates through the horizontal plate and extends to the bottom of the horizontal plate, and the bottom end of the measuring rod of the measuring instrument and the bottom end of the top column are located on the same horizontal plane.

[0009] As a preferred embodiment of this utility model, the threads at both ends of the lead screw have opposite directions, and an adjustment component is provided at one end of the lead screw. The adjustment component includes a worm gear, which is fixedly installed at one end of the lead screw. A worm is meshed with the lower end of the worm gear, and a rotating rod is provided at one end of the worm. One end of the rotating rod passes through the support and is provided with an adjustment handle.

[0010] As a preferred embodiment of this utility model, a support block is rotatably provided in the middle of the rotating rod, and the bottom end of the support block is fixedly connected to the top end of the base plate.

[0011] In a preferred embodiment of this utility model, the inclined block is slidably connected to the inner wall of the support, and the inclined block is slidably connected to the clamping seat.

[0012] As a preferred technical solution of this utility model, guide blocks are provided in the middle of both sides of the clamping seat, and guide rods are slidably provided in the middle of the guide blocks. The bottom end of the guide rod is fixedly connected to the top end of the support, and a spring is sleeved on the outside of the guide rod. The top end of the spring is fixedly connected to the bottom end of the guide block, and the other end is fixedly connected to the top end of the support.

[0013] As a preferred technical solution of this utility model, the movable component includes a fixed frame, which is fixedly installed on one side of the top of the base plate. An electric push rod is provided on one side of the top of the fixed frame. The telescopic rod of the electric push rod passes through the fixed frame and is provided with an installation ring. The surface of the installation ring is fixedly connected to the middle of the top of the horizontal plate by a number of bolts.

[0014] Compared with related technologies, the metal rod bending degree measuring device provided by this utility model has the following beneficial effects:

[0015] By placing the rod on top of two clamping seats and using a moving assembly, the horizontal plate moves vertically, ensuring that the top column and the measuring rods of the two measuring gauges fit tightly against the top of the rod. Using an adjusting assembly, rotating the adjusting handle allows the rotating rod and worm gear to rotate synchronously. The worm gear then drives the lead screw to rotate, causing the two inclined blocks to move synchronously and in opposite directions. During this process, the ingenious combination of the limiting plate, guide block, and guide rod ensures that the two clamping seats move smoothly and synchronously in the vertical direction. Combined with the action of the top column, this design easily applies pressure to both ends of the rod, increasing its height and causing it to bend. Using the measuring gauges, the degree of bending of the rod can be accurately measured. This measurement process not only ensures the synchronicity and stability of the two clamping seats during movement but also significantly improves the efficiency and accuracy of measuring the bending degree of metal rods, greatly reducing the operational burden on the measuring personnel.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 This utility model provides a metal rod bending degree measuring device, including a base plate 1, a support 2 at the middle of the top of the base plate 1, a horizontal plate 3 above the support 2, two measuring gauges 5 symmetrically arranged on the surface of the horizontal plate 3, the measuring gauges 5 being existing devices capable of measuring the bending degree of the metal rod itself, a top column 4 at the middle of the bottom of the horizontal plate 3, a lead screw 6 rotatably mounted inside the support 2, both ends of the lead screw 6 being threadedly connected to inclined blocks 7 via lead screw nuts, and a limiting plate 8 at the top of the inclined blocks 7, a clamping seat 9 slidably mounted outside the limiting plate 8, the top of the clamping seat 9 having a groove, by placing the rod 10... Inside the groove, the opposing movement of two inclined blocks 7, combined with the limiting plate 8, allows the two clamping seats 9 to move up and down synchronously. The bottom end of the top column 4 abuts against the rod 10. The two clamping seats 9 move upward, which facilitates the compression and lifting of both ends of the rod 10, allowing the rod 10 to bend. Combined with the measuring gauge 5, it is convenient to quickly measure the bending degree of the rod 10. The rod 10 is placed on the top of the two clamping seats 9. A moving component 12 is provided on one side of the top of the bottom plate 1 to facilitate the movement of the top column 4, which facilitates the movement of the top column 4 and the measuring gauge 5 in the vertical direction.

[0025] The threads at both ends of the lead screw 6 turn in opposite directions, which facilitates the synchronous adjustment of the inclined block 7. One end of the lead screw 6 is provided with an adjustment component 11, which includes a worm gear 1101. The worm gear 1101 is fixedly installed at one end of the lead screw 6. A worm 1102 is meshed below the worm gear 1101. One end of the worm 1102 is provided with a rotating rod 1103. One end of the rotating rod 1103 passes through the support 2 and is provided with an adjustment handle 1105. The adjustment handle 1105 is used to drive the rotating rod 1103 and the worm 1102 to rotate. Combined with the meshing worm gear 1101, it is convenient to drive the worm gear 1101 and the lead screw 6 to rotate in both directions.

[0026] A support block 1104 is rotatably provided in the middle of the rotating rod 1103. The bottom end of the support block 1104 is fixedly connected to the top end of the base plate 1, which facilitates the rotation of the rotating rod 1103 and ensures the stability of the rotating rod 1103 during rotation.

[0027] The inclined block 7 is slidably connected to the inner wall of the support 2, and the inclined block 7 is slidably connected to the clamping seat 9, so that the inclined block 7 plays a limiting and guiding role during the movement. The inclined block 7 is slidably connected to the clamping seat 9, so that the clamping seat 9 can move in the vertical direction.

[0028] Guide blocks 13 are provided in the middle of both sides of the clamping seat 9. Guide rods 14 are slidably provided in the middle of the guide blocks 13. The bottom end of the guide rods 14 is fixedly connected to the top end of the support 2. A spring 15 is sleeved on the outside of the guide rods 14. The top end of the spring 15 is fixedly connected to the bottom end of the guide blocks 13, and the other end is fixedly connected to the top end of the support 2.

[0029] The moving component 12 includes a fixed frame 1201, which is fixedly installed on one side of the top of the base plate 1. An electric push rod 1202 is provided on one side of the top of the fixed frame 1201. The telescopic rod of the electric push rod 1202 passes through the fixed frame 1201 and is provided with a mounting ring 1203. The surface of the mounting ring 1203 is fixedly connected to the middle of the top of the horizontal plate 3 by several bolts, so as to facilitate the movement of the horizontal plate 3 in the vertical direction by controlling the extension and retraction of the telescopic rod of the electric push rod 1202. This facilitates the bottom of the top column 4 and the bottom of the measuring rod of the measuring instrument 5 to contact the top of the rod body 10, which is convenient for subsequent testing.

[0030] The measuring rod of measuring gauge 5 passes through the horizontal plate 3 and extends to the bottom of the horizontal plate 3. The bottom end of the measuring rod of measuring gauge 5 and the bottom end of the top column 4 are located on the same horizontal plane, which facilitates the measurement of the bending degree of the rod 10.

[0031] The base plate 1 has four evenly spaced mounting holes 16 on its surface. The support 2 has several evenly spaced triangular plates on both sides, and the bottom of the triangular plates is fixedly connected to the top of the base plate 1. By using the mounting holes 16 on the base plate 1 and bolts, it is easy to install and fix the base plate 1. The triangular plates are used to support the support 2.

[0032] In use, first place the rod 10 on top of the two clamping seats 9, i.e., in the groove of the clamping seat 9. Then, by controlling the extension of the telescopic rod of the electric actuator 1202, the horizontal plate 3 is moved vertically, so that the bottom end of the top column 4 and the bottom end of the measuring gauge 5 are in contact with the top end of the rod 10. Then, control the electric actuator 1202 to stop working. Then, by using the set adjustment handle 1105, the rotating rod 1103 is rotated, which in turn drives the worm gear 1102 to rotate. Engaging with the meshing worm wheel 1101, it is easier to drive... The lead screw 6 rotates in the forward direction, which, combined with the lead screw nut, causes the two inclined blocks 7 on the surface of the lead screw 6 to move synchronously in opposite directions. Combined with the limiting plate 8 and the sliding clamping seat 9, the clamping seat 9 moves simultaneously. Combined with the guide block 13 and the guide rod 14, the two clamping seats 9 can move vertically, which facilitates the application of pressure to both ends of the rod 10 to increase its height. Combined with the support of the top column 4, the rod 10 bends. Combined with the measuring gauge 5, the degree of bending of the rod 10 can be accurately measured.

[0033] After the measurement is completed, the electric actuator 1202 is shortened again to move the horizontal plate 3, the top column 4 and the measuring instrument 5 upward. Then the measured rod 10 can be removed. Then the above steps are repeated to measure the bending degree of the subsequent rod 10 again.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
