Abstract
Description
Technical Field
[0001] This utility model relates to the field of parts processing technology, and in particular to a clamping device for assembling lamps. Background Technology
[0002] In the process of lighting fixture production and assembly, it is often necessary to screw wires into workpieces (such as lamp body brackets, connecting plates, or circuit board fixing holes) using screws. This requires an operator to hold an electric screwdriver in one hand and the wire in the other, without having a spare hand to press down on the workpiece.
[0003] Currently, existing technologies have attempted to clamp workpieces using methods such as temporary bonding with double-sided tape, designing special clamps for holding, or adding physical limiting structures at the bottom of the workpiece.
[0004] The above-mentioned existing technical solutions have the following defects: without the action of a clamping device, it is impossible for an operator to position the workpiece, making it difficult to maintain the stability of the workpiece. It is very easy for the workpiece to shift or rotate synchronously with the rotation of the screw, resulting in misalignment of the screw hole, skewed screw, or even stripped thread, which seriously affects the assembly efficiency and yield rate; double-sided adhesive is easy to leave residue and may damage the board surface, and special fixtures have complex structures, high costs, and poor versatility. Utility Model Content
[0005] The purpose of this invention is to provide a clamping device for assembling lamps to solve the problems existing in the prior art.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0007] A clamping device for assembling lamps includes a housing with a completely open top. The bottom of the housing has an upward-facing receiving groove, and a magnet is disposed inside the receiving groove. The front cross-section of the magnet is I-shaped. An elastic filling medium is disposed at the top of the interior of the housing. A first semicircular groove and a second semicircular groove are equally spaced from front to back on the left side of the housing.
[0008] By adopting the above technical solution, the bottom of both sides of the workpiece in this solution is located below the bottom of the screw hole. The shell is placed on the metal sheet, and the magnet at the bottom of the shell will firmly attract the shell to the metal sheet, preventing the shell from easily rotating due to its light weight and the elastic filling medium. Then, the workpiece is placed on the elastic filling medium. The first and second semicircular grooves on the left side of the shell can provide guidance for the wire. Under the elastic action of the elastic filling medium, the elastic filling medium can play a limiting role, fixing the workpiece in the elastic filling medium. Without the need for the operator to press the workpiece separately, it is possible to prevent the workpiece from rotating with the screw during the process of fixing the wire to the workpiece with the screw, so as to achieve the purpose of quickly screwing the screw into the workpiece.
[0009] In a further embodiment, a protective bag is fitted over the outer side of the elastic filling medium.
[0010] By adopting the above technical solution, the protective bag can separate the elastic filling medium from the workpiece, preventing the elastic filling medium from sticking to the workpiece and screws. In addition, the plastic wrap can lock in the moisture in the elastic filling medium for a certain period of time, preventing the clay elastic filling medium from losing moisture and solidifying due to long-term exposure to air, thus losing its elasticity.
[0011] In a further embodiment, the four corners of the shell are rounded. The elastic filling medium is modeling clay.
[0012] By adopting the above technical solution, the smooth design of the rounded corner structure prevents the casing from scratching operators during operation.
[0013] In a further embodiment, the bottom left and right sides of the housing are provided with through-holes, the through-holes are connected to the receiving groove, and a push-pull plate is slidably installed in the through-holes, with an upward protrusion at one end of each of the two push-pull plates that are opposite to each other.
[0014] By adopting the above technical solution, the magnet is I-shaped, and the two push-pull plates pass through the corresponding clearance holes at their close ends, and then are respectively locked at both ends of the magnet to prevent the magnet from falling off the bottom of the shell.
[0015] In a further embodiment, the length and width of the housing are both greater than the longest length of the workpiece.
[0016] By adopting the above technical solution, it is ensured that the shell can accommodate the workpiece.
[0017] In a further embodiment, the elastic filling medium is modeling clay.
[0018] By adopting the above technical solution, the elastic filling medium is preferably modeling clay. Modeling clay has elasticity. When the workpiece is placed on the top of the modeling clay, the worker presses the workpiece down, so that the top of the modeling clay forms a placement groove. The modeling clay outside the groove will limit the workpiece and firmly surround the modeling clay in the groove.
[0019] By adopting the above technical solution, during the lamp assembly process, the housing is first placed stably on a metal sheet. The magnet in the receiving groove at the bottom of the housing will function, firmly adhering the housing to the metal sheet and preventing rotation during operation due to the light weight of the housing and the elastic filling medium. Next, the workpiece to be assembled is placed on the clay inside the housing, with its top higher than the top of the housing. The worker presses down on the workpiece, and the clay is compressed by its own elasticity, forming a placement groove at the top. The clay outside the groove provides a limiting effect on the workpiece, firmly surrounding it within the groove. This eliminates the need for the worker to press the workpiece separately. This device effectively prevents the workpiece from rotating with the screws when fixing the wires to the workpiece, thus enabling the screws to be tightened quickly. The first and second semi-circular grooves, evenly spaced from front to back on the left side of the housing, guide the wires, resulting in a more organized wire layout. Since the length and width of the housing are both greater than the longest length of the workpiece, it can accommodate workpieces of various sizes and shapes. Furthermore, the clay is covered with a protective bag, which prevents the clay from sticking to the workpiece and screws, and also locks in the moisture for a certain period, preventing it from hardening and losing its elasticity due to prolonged exposure to air. This clamping device is easy to operate and effectively improves the efficiency and quality of lamp assembly.
[0020] In summary, this utility model has the following beneficial effects:
[0021] 1. By placing the housing on a metal sheet, the magnet at the bottom of the housing will firmly attach the housing to the metal sheet, preventing the housing from easily rotating due to its light weight and the elastic filling medium. Then, the workpiece is placed on the elastic filling medium. The first and second semicircular grooves on the left side of the housing can provide guidance for the wire. Under the elastic action of the elastic filling medium, the elastic filling medium can play a limiting role, fixing the workpiece in the elastic filling medium. Without the need for the operator to press the workpiece separately, it can prevent the workpiece from rotating with the screw during the process of fixing the wire to the workpiece with screws, which can achieve the effect of quickly screwing the screw into the workpiece.
[0022] 2. By setting the first semicircular groove and the second semicircular groove, the wire is placed in the first semicircular groove and the second semicircular groove respectively, thereby providing a guiding effect for the placement of the workpiece. Then, the workpiece is placed completely against the inner wall of the top of the shell, which can further prevent the workpiece from rotating with the screw during the screw-in process.
[0023] 3. By sliding push-pull plates on the bottom of the left and right sides of the housing, when a magnet needs to be installed at the bottom of the housing, the push-pull plates on both sides are driven to hold the magnet in the receiving groove of the housing. When the magnet does not need to be installed, the two push-pull plates are pulled away from each other, so that the push-pull plates no longer hold the magnet, and the magnet falls out from the bottom of the housing, which can facilitate the installation and removal of the magnet.

[0029] Example 1:
[0030] like Figures 1-2As shown, a clamping device for assembling lamps includes a housing 1, which has a completely open top and rounded corners. The bottom of the housing 1 has an upward-facing receiving groove, and a magnet 4 is installed inside the receiving groove. The front cross-section of the magnet 4 is I-shaped. An elastic filling medium 2 is installed at the top inside the housing 1, and a protective bag is fitted on the outside of the elastic filling medium 2. The left side of the housing has a first semi-circular groove and a second semi-circular groove at equal intervals from front to back. The length and width of the housing 1 are both greater than the longest length of the workpiece. The elastic filling medium 2 is modeling clay. The bottom left and right sides of the housing 1 have through-holes that communicate with the receiving groove. Push-pull plates 3 are slidably installed inside the through-holes, and the two push-pull plates 3 have upward protrusions at their opposite ends.
[0031] Specific implementation process: During lamp assembly, the housing 1 is first placed stably on a metal sheet. The magnet 4 in the receiving groove at the bottom of the housing 1 will function, firmly adhering the housing 1 to the metal sheet, preventing rotation during operation due to the light weight of the housing 1 and the elastic filling medium 2. Next, the workpiece to be assembled is placed on the clay at the top inside the housing 1. The worker presses down on the workpiece, and the clay is squeezed due to its elasticity, forming a placement groove at the top. The clay outside the groove provides a limiting effect on the workpiece, firmly surrounding it within the groove. This effectively prevents the workpiece from being rotated without the worker pressing it down separately. When the wire is fixed to the workpiece by the screw, the workpiece rotates with the screw, thereby enabling the screw to be quickly screwed into the workpiece. The first and second semicircular grooves, which are equally spaced from front to back on the left side of the housing 1, can provide guidance for the wire, making the wire layout more regular. Since the length and width of the housing 1 are both greater than the longest length of the workpiece, and the clay is covered with a protective bag, it can prevent the clay from sticking to the workpiece and the screw, and can also lock in the moisture in the clay for a certain period of time, preventing it from hardening due to long-term exposure to air and losing its elasticity. This clamping device is easy to operate and can effectively improve the efficiency and quality of lamp assembly.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments disclosed in this utility model according to the specific circumstances.
[0033] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
