It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1 and 2, the present invention provides an online strip thickness measuring device.
The strip steel on-line thickness measuring device comprises an underframe 1, a transverse U-shaped support 2 (as shown in figure 1, the U-shaped support is placed upside down, the open end of the U-shaped support corresponds to strip steel to be detected), and a laser thickness gauge (not shown in the figure), wherein a lower supporting leg 21 of the U-shaped support is slidably connected with the underframe, one sensor 31 of the laser thickness gauge is arranged on the upper surface of the end part of the lower supporting leg 21 of the U-shaped support, and the other sensor 32 of the laser thickness gauge is arranged on the lower surface of the end part of an upper supporting leg 22 of the U-shaped support; one side of the lower supporting leg of the U-shaped support is horizontally provided with a rack 42, one side of the underframe is provided with a driving motor 40, a main shaft of the driving motor is sleeved with a gear 41, and the gear 41 is meshed with the rack 42. The laser thickness gauge itself is prior art and therefore the figures only schematically show the position of its two sensors.
Further, two linear sliding rails 51 are arranged on the chassis 1 in parallel, two linear bearings 52 are arranged on the lower surface of the lower leg of the U-shaped bracket, and each linear sliding rail is connected with the corresponding linear bearing. Through setting up two linear slide rail, can support the U-shaped support steadily, guarantee that the U-shaped support can steady rectilinear movement.
As shown in fig. 1, further, two ends of each linear guide rail are respectively provided with an anti-collision block 59 (for convenience of observation, the anti-collision blocks are not shown in fig. 2). The anti-collision block is usually a rubber anti-collision block, so that even if an electrical fault occurs, the U-shaped support moves out of the stroke range and then abuts against the anti-collision block, and further accidents are avoided.
Further, the length of the rack 42 is equal to the length of the lower leg 21 of the U-shaped bracket, and the length of each linear slide rail is equal to twice the length of the linear bar. By the arrangement, the U-shaped support is always positioned on the bottom frame when the U-shaped support linearly moves along the length direction of the whole rack.
Preferably, the driving motor 40 is a servo motor, which can control the moving position of the U-shaped bracket more precisely.
Preferably, the lower leg 21 and the upper leg 22 of the U-shaped bracket are equal in size, which reduces the manufacturing cost of the U-shaped bracket.
In a further preferred embodiment, a supporting plate is fixed on the bottom frame, the supporting plate is arranged on one side of the opening of the corresponding U-shaped support, a brush is detachably connected to the supporting plate, and the brush is arranged corresponding to the two sensors of the laser thickness gauge. When being stained with debris or more dust on two sensors of laser thickness gauge, can block the light of sensor and jet out, consequently need clear up debris and dust on two sensors of laser thickness gauge. Utilize driving motor drive U-shaped support to remove for two sensors of the laser thickness gauge on the U-shaped support can contact with the brush, realize clearing up the debris and the dust on sensor surface.
The cross section of the supporting plate is inverted L-shaped, the upper side surface and the lower side surface of one end connected with the hairbrush are provided with convex patterns, the hairbrush is provided with a groove with a cross-shaped cross section, the groove and the convex patterns are matched, and one end of the supporting plate is also provided with a stop block. Preferably, the brush passes through the recess with the backup pad and closely laminates with the burr for the brush can only remove along the burr direction, and sets up the dog in the one end of backup pad, is used for restricting the brush position, makes the connection dismantled of brush, makes things convenient for the dismouting of brush to change.
Furthermore, a dust baffle plate is fixed on the supporting plate, is arranged on the outer side of the brush and corresponds to the lower supporting leg and the lower supporting leg. Wherein, the dust board is made by compressible flexible material, for example the sponge for when needs clear up debris and dust to two sensors of laser thickness gauge, driving motor drive U-shaped support removes, compresses the dust board, makes the brush expose in the dust board outside and with the sensor contact, realizes the clearance, and when the U-shaped support moved away the dust board position, the outside of brush was arranged in again to the dust board utilization restoring force of self, the dustproof protection to the brush when realizing the leisure.
In a further preferred embodiment, the dust removing brushes are arranged in front of the upper supporting leg and the lower supporting leg of the U-shaped support, the front is the front where the steel belt moves, so that the steel belt can clean impurities and dust before detection is realized, and the dust removing brushes are preferably fixed on the side surfaces of the upper supporting leg and the lower supporting leg.
The present invention does not particularly limit the structure of the base frame based on stably supporting various components (e.g., U-shaped brackets, driving motors, etc.) disposed thereon.
The following brief description is made on the working principle: when the thickness of the strip steel needs to be detected, the driving motor rotates to drive the U-shaped support to move towards the strip steel until the strip steel extends between the upper supporting leg and the lower supporting leg of the U-shaped support, and the two sensors arranged on the upper supporting leg and the lower supporting leg respectively measure the position of the upper surface and the position of the lower surface of the strip steel to be detected in an up-and-down correlation mode, so that the thickness of a detected body is measured. As the strip steel keeps moving forwards in the production process, the laser thickness gauge detects and records the thickness of the strip steel in real time, namely, the online thickness measurement of the strip steel is realized. When the thickness of the strip steel does not need to be measured, the driving motor is reversely rotated to enable the U-shaped support to be far away from the strip steel.
Through the analysis, the strip steel on-line thickness measuring device provided by the invention mainly has the following advantages: (1) the whole structure is simple, and the operation is easy. (2) The U-shaped support is simple in driving mode, the rack, the gear and the driving motor are easy to install, the occupied installation space is small, and the occupied area of the strip steel online thickness measuring device can not be increased.
It should be understood that equivalents and modifications of the technical solution and inventive concept thereof may occur to those skilled in the art, and all such modifications and alterations should fall within the protective scope of the present invention.
