Description

Technical Field

[0001] The utility model relates to the technical field of clamps, and mainly relates to a simple clamp suitable for a lampshade processing device. Background Art

[0002] A lampshade is a cover placed around the flame or on the bulb to focus light or protect against wind and rain. Lampshades come in different styles depending on the shape of the lamp.

[0003] like Figure 1 As shown in the figure, this is a lampshade for a lamp body. Holes at locations A and B need to be punched in the lampshade. Traditionally, these holes are punched manually with a handheld drill. However, this method has low processing efficiency and a high defective rate. To improve processing efficiency and product quality, CNC lathes are now used to punch the lampshade. To ensure the stability of the lampshade during drilling, a fixture is needed to secure the lampshade. Utility Model Content

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of devices consistent with certain aspects of the present application, as detailed in the appended claims.

[0020] The terms used in this application are for the purpose of describing specific embodiments only and are not intended to limit this application. Unless otherwise defined, technical or scientific terms used in this application should have the same ordinary meaning as those understood by persons of ordinary skill in the art to which this invention belongs. The use of "a," "an," and similar terms in this specification and claims does not indicate a limitation of quantity, but rather indicates the presence of at least one. "A plurality" includes two and is equivalent to at least two. "Includes" or "comprising" and similar terms mean that the elements or objects preceding "includes" or "comprising" include the elements or objects listed after "includes" or "comprising," and their equivalents, and do not exclude other elements or objects. "Connected" or "connected" and similar terms are not limited to physical or mechanical connections and may include electrical connections, whether direct or indirect. As used in this specification and the appended claims, the singular forms "a," "the," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0021] Please refer to Figure 2-3 , a simple fixture for a lampshade processing device, including a base 1, which has two grooves that communicate with each other to form a cross shape. The groove consists of a mounting groove (not marked in the figure) and a slide groove 2. A support 3 is installed inside the mounting groove, and the support 3 is fixed to the base 1 by a countersunk screw. A screw 4 is installed in the slide groove 2, and the middle part of the screw 4 is installed on the support 3. A raised stopper 5 is provided on the support 3, and the stopper 5 and the support 3 are an integrated structure. A slider 6 is installed on each of the two ends of the screw 4, and the bottom of the slider 6 is installed in the slide groove 2. An assembly cavity 7 is formed between the slider 6 and the support 3, that is, each of the two ends of the support 3 has an assembly cavity 7, and the lampshade 11 can be assembled into the assembly cavity 7 and clamped and fixed by the slider 6.

[0022] Furthermore, the screw rod 4 has oppositely directed threads at both ends. For example, if the left end of the screw rod 4 has a left-handed thread, the right end has a right-handed thread. Nuts 8 are mounted inside the two sliders 6, each matching the threads of the screw rod 4. The nut 8 mounted on the left end of the screw rod 4 matches the left-handed thread, while the nut 8 mounted on the right end of the screw rod 4 matches the right-handed thread. Based on this design, the two sliders 6 can be moved toward or away from each other by rotating the screw rod 4, and the stopper 5 can be used to clamp and secure the lampshade 11.

[0023] Furthermore, a clamping plate 9 is installed on the inner side of the slider 6, and the clamping plate 9 is fixed to the slider 6 by welding or fasteners. The inner side surface of the clamping plate 9 is a tooth-like structure. The clamping surface of the tooth-like structure increases the friction between the clamping plate 9 and the lampshade 11, and an assembly cavity 7 is formed between the clamping plate 9 and the support 3.

[0024] Furthermore, a baffle 10 is provided on one side of the support 3 , and the baffle 10 is fixed to the support 3 by welding or fasteners. The height of the baffle 10 is higher than the lampshade 11 , and the baffle 10 is used to block the lampshade 11 and limit the position of the lampshade 11 .

[0025] The utility model is a simple fixture for a lampshade 11 processing device. Its working principle is combined with the instructions attached. Figure 4 illustrate:

[0026] The base 1 can be fixedly mounted on a CNC lathe, which is a common CNC lathe with a punching mechanism on the market. Then, the two sides of the lampshade 11 are placed into the assembly cavity 7. At this time, the two inner sides of the lampshade 11 will fit with the two sides of the stop block 5. One end of the lampshade 11 is brought into contact with the baffle 10. Use a wrench to rotate the screw 4. With the cooperation of the screw 4 and the nut 8, the two sliders 6 and the baffle 10 are driven to move toward each other and gradually approach the lampshade 11 until the inner side of the baffle 10 fits tightly with the outer side of the lampshade 11, completing the clamping action of the lampshade 11, which is convenient for the CNC lathe to punch holes in the lampshade 11.

[0027] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
