Description

Technical Field

[0001] The utility model belongs to the field of information parameter correction auxiliary equipment for mechanical marking machines, and in particular relates to a vibration protection information acquisition device for a mechanical marking machine. Background Art

[0002] At present, in order to mark the product serial number or other marks on the outer wall of parts and workpieces, a marking machine is often needed to mark the products. At present, the more commonly used marking machines are mechanical marking machines and laser marking machines. Both devices are more commonly used by enterprises, but mechanical marking machines use the physical form of pneumatic stamping to hit the surface of parts to produce marks and form the information to be marked, while laser marking machines are simpler. The laser generated by the laser head ablates the information to be marked on the surface of the parts. The principles of these two devices are different, and the prices are also different. The price of laser marking machines is different. The price is much higher than that of mechanical marking machines. Therefore, for small enterprises with low usage, mechanical marking machines are the preferred equipment. However, since the mechanical marking machine itself relies on pneumatic stamping to hit the outer surface of the part to produce marks, impact force will be formed on the surface of the part. Marking is not completed in one go, but is achieved through continuous striking. Therefore, the part will continue to be subjected to impact force during the marking process. When the part is clamped eccentrically or the caliper is clamped unsteadily, the mark will appear crooked, and the marking has been completed and cannot be changed. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a vibration protection information collection device for a mechanical marking machine. A collection component is sleeved on the end of the tube to be marked. When the caliper component clamps the tube to be marked, the end of the support plate is pushed outward so that the detection needle remains fixed and abuts against the detection plate. When the tube to be marked vibrates during the marking process, the vibration will be fed back to the detection plate to form vibration information for the debugging personnel to collect data and calibrate the marking machine.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A vibration protection information collection device for a mechanical marking machine comprises a marking machine, a collection component and a tube to be marked, the marking machine comprises a base, a telescopic seat, a marking head and a rotating seat, the marking head is connected to the base via a telescopic seat, the rotating seat is arranged on the base, a caliper assembly is arranged on the rotating seat, the caliper assembly comprises a caliper seat and a caliper head, a clamping cavity is arranged in the caliper seat, a non-slip surface is arranged on the lower end surface of the caliper head, the caliper head comprises at least three groups and is circumferentially distributed at the opening of the clamping cavity, and the detection plate is arranged at the bottom of the clamping cavity.

[0006] The collection assembly includes a clamping tube, a clamping member and a detection member, the detection member includes a detection needle and a detection plate, the detection needle is connected to the clamping tube through the clamping member, the tube to be marked is inserted in the clamping tube, the caliper assembly is clamped on the outer wall of the clamping tube, the detection plate is arranged in the caliper assembly, the detection needle abuts on the detection plate, and the marking head points to the outer wall of the tube to be marked; the clamping member includes a clamping seat and a support plate, the clamping seat is axially arranged on the outer wall of the clamping tube, the support plate is formed by connecting a short plate and a long plate to form an L-shaped structure, the connection between the short plate and the long plate can be rotatably connected to the clamping seat, the end of the short plate extends out of the front end of the clamping tube, the rear end of the caliper head is provided with a pressing surface, the end of the short plate abuts on the pressing surface, and the end of the long plate extends out of the rear end of the clamping tube; the detection member also includes a spring and a stabilizing seat, the stabilizing seat is connected to the end of the long plate through a spring, and the detection needle is arranged on the stabilizing seat.

[0007] The clamping seat, support plate and spring include at least three groups and are distributed in a circle on the outer wall of the clamping tube with the axis of the clamping tube as the rotation axis. The stabilizing seat is suspended in the connection of at least three groups of springs and overlaps on the axis of the clamping tube. An information transmission head is provided on the stabilizing seat. A limiting plate is provided in the clamping tube, and the limiting plate is arranged on the inner cavity of the clamping tube. One end of the tube to be marked can be abutted and connected to the limiting plate. A through hole for the information transmission head to pass through is provided at the center of the limiting plate.

[0008] The vibration protection information collection device of the mechanical marking machine adopts this structure. The marking machine provides basic support force through the base. The telescopic seat on the base provides driving force for the marking head to extend and retract up and down. The rotating seat provides support for the caliper assembly. At least three groups of caliper heads on the caliper assembly are distributed in a circle at the opening of the clamping cavity. After the marking tube is inserted into the clamping cavity, the three groups of caliper heads are driven by electric energy to move toward the center of the circle to clamp the tube to be marked. The caliper seat is divided into a front end seat and a rear end seat. The front end seat is rotatably connected to the rear end seat. The front end seat is driven to rotate by the driving motor at the lower end, and the rear end seat is in a fixed state. The marking head pneumatically strikes downward on the tube to be marked for marking. This is a relatively common mechanical marking machine structure at present, and its marking form will not be described in detail here.

[0009] Since the tube to be marked is clamped and rotated, it is very likely that the clamping eccentricity or the clamping instability of the caliper will occur without calibration. Therefore, before the marking machine is put into use, it needs to be calibrated. Then, after the tube to be marked is clamped, it is directly driven to rotate. If it is eccentric, the tube to be marked will be in an eccentric rotation state, which is not accurate to observe with the human eye. Therefore, the data of this eccentric state is collected through the acquisition component, and the eccentric data can be more intuitively seen for calibration by technicians. The clamping tube of the acquisition device is installed at the end of the tube to be marked, and the clamping tube is clamped. There are three groups of clamping components distributed in a circle on the outer wall of the tube. The clamping components are composed of a clamping seat and a support plate. The clamping seat provides a rotational support for the support plate. The short plate of the support plate extends out of the front end of the clamping tube, and the long plate of the support plate extends out of the rear end of the clamping tube. Therefore, after the tube to be marked with the clamping tube is inserted into the clamping cavity, it abuts against the limit plate in the clamping tube to prevent the tube to be marked from being over-inserted. The clamping tube is rotated until the ends of the three groups of short plates abut against the pressing surfaces at the rear ends of the three groups of caliper heads respectively. When the pneumatic caliper head is clamped toward the tube to be marked, the pressing surface will also press the short plate downward. Due to the connection between the short plate and the long plate, the clamping tube is clamped in the direction of the tube to be marked. The joint is rotatably connected to the clamping seat, so the end of the long plate will tilt upward, and the ends of the three groups of long plates are connected to the stable seat through springs. Under the deformation force of the spring, the stable seat will be pulled straight from three sides, so that the stable seat is kept on the axis of the clamping tube and in a stable state. The detection needle on the stable seat abuts against the detection plate at the bottom of the clamping cavity. Therefore, when the tube to be marked is in an eccentric state, the detection needle cannot abut against the center of the detection plate. When the caliper head is driven by the front end seat to rotate the tube to be marked, the detection needle also rotates accordingly. At this time, the detection plate is at the bottom of the fixed rear end seat. Therefore, when the tube to be marked is When eccentric, the contact point between the detection needle and the detection plate cannot be maintained at the center of the detection plate, and the circular contact state will be presented through the information transmission head on the stable seat to send the signal through the through hole to the technician's equipment to obtain digitized content. The information sending and digitized presentation state are currently known technologies and will not be elaborated on here. If the vibration generated during the marking process of the marking head causes the tube to be marked to loosen, scattered contact states will be presented on the detection plate. These data will also be presented on the technician's equipment for the technician to judge and calibrate the marking machine.

[0010] Furthermore, the collection assembly also includes a reducer seat, which is detachably connected to the inner wall of the clamping tube, and the lower end surface of the reducer seat abuts against the outer wall of the tube to be marked. The reducer seat includes at least three groups and is distributed in a circular array in the clamping tube.

[0011] Compared with the prior art, the advantages of the utility model are: during the process of pressing the support plate, the stabilizing seat is stretched and kept stable by the caliper head, and the detection needle is abutted against the detection plate. If a circular contact state is present during the rotation of the tube to be marked, it can be determined that the tube to be marked is eccentric; if a scattered contact state is present, it can be determined that the caliper head is loose due to unstable clamping. The marking machine is calibrated on this basis, and it has a good calibration effect for the marking machine that has just been completed. The detection plate can be adapted according to the connecting hole of the rear end seat. The quick-release installation on the rear end seat can use the central connecting hole of the rear end seat as a reference to realize the calibration of large-scale marking machines.

[0027] Description of the working method of this utility model:

[0028] The vibration protection information collection device of the mechanical marking machine adopts the structure, the marking machine 1 provides basic support force through the base 11, the telescopic seat 12 on the base 11 is used to provide a driving force for the marking head 13 to extend and retract up and down, and the rotating seat 14 provides support for the caliper assembly 15. At least three groups of caliper heads 152 on the caliper assembly 15 are distributed in a circle at the opening of the clamping cavity 153. After the marking tube 3 is inserted into the clamping cavity 153, the three groups of caliper heads 152 are driven by electric energy to move toward the center of the circle to clamp the marking tube 3 The caliper seat 151 is divided into a front end seat 1511 and a rear end seat 1512. The front end seat 1511 is rotatably connected to the rear end seat 1512. The front end seat 1511 is driven to rotate by a driving motor at the lower end, and can also be driven by a belt drive. The transmission form is not described in detail here. The rear end seat 1512 is in a fixed state. The marking head 13 pneumatically strikes downward on the tube 3 to be marked for marking. This is a relatively common mechanical marking machine 1 structure at present, and the marking form is not described in detail here.

[0029] Since the tube 3 to be marked is likely to be clamped eccentrically or the clamping is unstable without calibration during the process of being clamped and rotating, the marking machine 1 needs to be calibrated before it is put into use. Then, the tube 3 to be marked is clamped and then driven to rotate directly. If it is eccentric, the tube 3 to be marked will be in an eccentric rotating state, which is not accurate when observed by human eyes. Therefore, the data of this eccentric state is collected by the acquisition component 2, and the eccentric data can be more intuitively seen for calibration by technicians. The clamping tube 21 of the acquisition device is mounted on the end of the tube 3 to be marked, and three groups of clamping members 22 are circumferentially distributed on the outer wall of the clamping tube 21. The clamping member 22 is composed of a clamping seat 221 The clamping seat 221 is used to provide a rotational support for the support plate 222. The short plate 2221 of the support plate 222 extends out of the front end of the clamping tube 21, and the long plate 2222 of the support plate 222 extends out of the rear end of the clamping tube 21. Therefore, after the tube 3 to be marked with the clamping tube 21 is inserted into the clamping cavity 153, it abuts against the limit plate 211 in the clamping tube 21 to prevent the tube 3 to be marked from being over-inserted. The clamping tube 21 is rotated until the ends of the three groups of short plates 2221 abut against the pressing surfaces 1522 at the rear ends of the three groups of clamp heads 152. When the pneumatic clamp heads 152 are clamped toward the direction of the tube 3 to be marked, the pressing surfaces 1522 will also press the short plates 2221 downward. The ends of the three groups of long plates 2222 are connected to the stabilizing seat 234 through springs 233. The stabilizing seat 234 is pulled straight from three sides under the deformation force of the springs 233, so that the stabilizing seat 234 is kept on the axis of the clamping tube 21 and is in a stable state. The detection needle 231 on the stabilizing seat 234 abuts against the detection plate 232 at the bottom of the clamping cavity 153. Therefore, when the tube 3 to be marked is in an eccentric state, the detection needle 231 cannot abut against the center of the detection plate 232. When the caliper head 152 is driven by the front end seat 1511 to rotate the tube 3 to be marked, the detection needle 231 also rotates accordingly. At this time, the detection plate 232 is fixed. The bottom of the rear end seat 1512, so when the tube 3 to be marked is eccentric, the contact point between the detection needle 231 and the detection plate 232 cannot be maintained at the center of the detection plate 232, and the circular contact state is presented through the information transmission head 235 on the stable seat 234 to send the signal through the through hole 2111 to the technician's equipment to obtain the digitized content. The information sending and digitized presentation state are currently known technologies and will not be described in detail here. If the vibration generated during the marking process of the marking head 13 causes the tube 3 to be marked to become loose, a scattered contact state will be presented on the detection plate 232. These data will also be presented on the technician's equipment for the technician to judge and calibrate the marking machine 1.

[0030] In order to adapt to more parts of different sizes for calibration, at least three groups of detachable reducers 24 are provided on the inner wall of the clamping tube 21. The reducers 24 can be replaced to adapt to parts of different diameters, so that the marking machine 1 can be adapted to various parts.

[0031] The beneficial effect of the utility model is that: during the process of pressing the support plate 222, the stabilizing seat 234 is stretched and kept stable by the caliper head 152, and the detection needle 231 is abutted against the detection plate 232. If a circular contact state is present during the rotation of the tube 3 to be marked, it can be determined that the tube 3 to be marked is eccentric, and if a scattered contact state is present, it can be determined that the caliper head 152 is loose due to unstable clamping. The marking machine 1 is calibrated on this basis, and it has a good calibration effect for the marking machine 1 that has just been completed. The detection plate 232 can be adapted according to the connecting hole of the rear end seat 1512. The quick-release installation on the rear end seat 1512 can use the central connecting hole of the rear end seat 1512 as a reference to realize the calibration of large-scale marking machines 1.

[0032] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
