Description

Technical Field

[0001] The utility model relates to the technical field of solenoid valve coils, in particular to a laser marking and fixing component suitable for solenoid valve coils. Background Art

[0002] Solenoid valves are industrial equipment controlled by electromagnetics. They are basic automation components used to control fluids. They are actuators and are not limited to hydraulic or pneumatic. They are used in industrial control systems to adjust the direction, flow, speed and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, and the accuracy and flexibility of the control can be guaranteed. The solenoid valve is composed of a solenoid valve coil and a magnetic core. The solenoid valve coil is directly installed on the valve body. When the coil is energized or de-energized, the operation of the magnetic core will cause the fluid to pass through the valve body or be cut off, so as to achieve the purpose of changing the direction of the fluid.

[0003] like Figure 1-2 As shown, there is an existing solenoid valve coil 2, with three power plugs 21 on one side of the shell. The product needs to be engraved with relevant information on multiple surfaces of the shell using a laser marking machine using a laser beam before leaving the factory. At present, for this product, it is generally placed one by one on the working platform of the laser marking machine or placed on a simple groove mold matching the shell for marking. In actual work, if you want to laser mark multiple surfaces of the same solenoid valve coil, you need to manually readjust the solenoid valve coils one by one before marking, which has low work efficiency. In addition, because the product is symmetrical in shape, the product is often placed in the wrong direction, resulting in incorrect marking position. Utility Model Content

DETAILED DESCRIPTION

[0032] The following is further described in detail through specific implementation methods:

[0033] like Figure 1-14 As shown, this embodiment shows a laser marking fixing component suitable for a solenoid valve coil, comprising a laser marking machine 1 for emitting a laser beam, a solenoid valve coil 2 with three power plugs 21 placed on a workbench of the laser marking machine 1, and a clamp 3 for fixing a plurality of the solenoid valve coils 2; the clamp 3 comprises a clamp body 31 and a plurality of plug-in clips 32 embedded in the clamp 3 and matching the three power plugs 21 of the solenoid valve coil 2; through the clamping connection between the power plug 21 and the plug-in clip 32, a plug-in and detachable connection between the clamp 3 and the solenoid valve coil 2 is achieved. The three power plugs 21 of the solenoid valve coil 2 are connected by contact-type clamping by the plug-in clamp 32, so that the clamp 3 can quickly clamp the solenoid valve coil 2 in a pluggable manner, and at the same time, the solenoid valve coil 2 after clamping has the same direction and interval. After completing the marking of one surface, it is only necessary to rotate the clamp to continue to mark other surfaces accordingly, thereby greatly improving the marking efficiency and marking accuracy of the laser marking machine 1.

[0034] Further explanation, such as Figure 4-9 As shown, in this embodiment, the clamp body 31 includes a clamp groove 311 that matches the plug-in clamp 32; the plug-in clamp 32 is detachably embedded in the clamp groove 311 through a threaded connection; the bottom of the clamp groove 311 is provided with a threaded mounting hole 312 for connecting the plug-in clamp 32 and a plug through hole 313 that matches the power plug 21. Specifically, the plug-in clamp 32 is detachably threadedly connected to the clamp body 31 through the clamp groove 311, and the plug-in clamp 32 is designed as a module that can be independently disassembled and assembled, which is more portable and more convenient for later maintenance.

[0035] Further, such as Figure 10-14As shown, the plug-in connector 32 in this embodiment includes a connector body 321, a pair of elastic rollers 322 embedded in the connector body 321 for clamping the power plug 21, a pair of baffles 323 embedded in the connector body 321 for limiting the elastic rollers 322, and a cover plate 324 fixed to the top of the connector body 321 by threaded connection for limiting the baffle 323; the connector body 321 includes roller grooves 3211 arranged in the middle of two side surfaces and arranged in the horizontal direction for clamping the elastic rollers 322 respectively, two baffle grooves 3212 arranged in the vertical direction for clamping the baffles 323 respectively, a cover plate groove 3213 arranged at the top for clamping the cover plate 324, and a connector through-hole 3214 matching the connector through-hole 313. The elastic roller 322 abuts against the bottom of the roller groove 3211; specifically, the elastic roller 322 is limited by the baffle 323 and abuts against the bottom of the roller groove 3211. When the power plug 21 of the solenoid valve coil 2 passes through the plug through hole 313 and is inserted into the plug through groove 3214, the elastic rollers 322 on both sides of the power plug 21 form a contact abutment with the power plug 21, thereby realizing the rapid clamping of the solenoid valve coil 2 by the clamp 3.

[0036] Further explanation, in further implementation of this embodiment, as Fig.14 As shown, the bottom of the roller groove 3211 is provided with an arc-surface through-slot 3215; the width of the arc-surface through-slot 3215 is smaller than the cross-sectional diameter of the elastic roller 322. Further, in these embodiments, the arc surface of the arc-surface through-slot 3215 matches the cylindrical outer wall of the elastic roller 322. Further, as Fig.14 As shown, in these embodiments, the baffle 323 penetrates the roller groove 3211. The baffle 323 limits the elastic roller 322 to abut against the roller groove 3211. Since the width of the arc-surface through-notch 3215 is smaller than the cross-sectional diameter of the elastic roller 322, a part of the cylindrical body of the elastic roller 322 protrudes outside the arc-surface through-notch 3215, thereby realizing the contact abutment of the elastic roller 322 against the power plug 21.

[0037] like Figure 1-9 and Figure 15-16As shown, another embodiment shows a laser marking fixing component suitable for a solenoid valve coil, comprising a laser marking machine 1 for emitting a laser beam, a solenoid valve coil 2 with three power plugs 21 placed on a workbench of the laser marking machine 1, and a clamp 3 for fixing a plurality of the solenoid valve coils 2; the clamp 3 comprises a clamp body 31 and a plurality of plug-in connectors 32 embedded in the clamp 3 and matching the three power plugs 21 of the solenoid valve coil 2; the plug-in and detachable connection between the clamp 3 and the solenoid valve coil 2 is achieved by the clamping connection between the power plug 21 and the plug-in connector 32. Further, as Figure 4-9 As shown, the clamp body 31 in this embodiment includes a clamp groove 311 matching the plug-in clamp 32; the plug-in clamp 32 is detachably embedded in the clamp groove 311 through a threaded connection; the bottom of the clamp groove 311 is provided with a threaded mounting hole 312 for connecting the plug-in clamp 32 and a plug through hole 313 matching the power plug 21.

[0038] Further explanation, in further implementation of this embodiment, as Figure 8-9 and Figure 15-16 As shown, the outer wall of the inserting clip 32 is provided with a pair of limiting protrusions 325, and correspondingly, the clip groove 311 is provided with a limiting groove 3111 matching the limiting protrusion 325; the limiting groove 3111 is contactably limitedly connected with the limiting protrusion 325. Specifically, the contactably limited connection between the limiting groove 3111 and the limiting protrusion 325 makes the installation of the inserting clip 32 in the form of an independent module more portable and stable.

[0039] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
