Description

Technical Field

[0001] The utility model relates to the technical field of nut delivery and installation, in particular to a double-side deep cavity nut installation device. Background Art

[0002] Deep cavity nuts are specialized nuts used in deep cavities or sealed enclosures, primarily for securing and locking components. The design and application of these nuts are primarily focused on aerospace engines, automated assembly systems, and other fields.

[0003] Existing products are designed with deep cavity structures on both sides, which require nuts to be placed inside for tightening. However, due to the small size of the nuts, traditional manual assembly operations are difficult, and the pressing force when manually pressing the nuts to be installed into the deep cavity of the product is difficult to control, which ultimately makes it difficult to connect and tighten the subsequent bolts with the deep cavity nuts.

[0004] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a double-sided deep cavity nut installation device to solve the above problems.

[0005] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solution of the present invention and facilitating the understanding of those skilled in the art. It cannot be assumed that the above contents are well known to those skilled in the art simply because they are explained in the background technology of the present invention. Utility Model Content

[0006] In order to overcome the deficiencies in the above-mentioned prior art, the purpose of the present utility model is to disclose a double-sided deep cavity nut installation device to solve the problem of insufficient assembly position accuracy due to unstable pressing force during the process of the nut entering the deep cavity.

[0007] The utility model discloses a double-sided deep cavity nut installation device, comprising a base, a positioning block for positioning a product provided on the base, a support block further provided on the base, the support block being arranged on the side of the positioning block away from the product, a guide groove corresponding to the deep cavity for placing the product nut provided on the support block, the guide groove being used to position and place the nut to be installed. A push plate is slidably connected in the guide groove, and is used to push the nut to be installed along the guide groove into the deep cavity of the product for placement. A pull rod is connected to the side of the push plate away from the product, and a spring is further connected between the pull rod and the support block. The spring provides power to the pull rod and the push plate connected thereto, and uses elastic force instead of manpower to press the nut to be installed into a designated position in the deep cavity of the product.

[0008] Preferred technical solution: A guide slide is connected to the side of the guide groove away from the product, the push plate and the pull rod are connected by a movable block, the movable block is slidably set in the guide slide, and the movable block and the push plate connected to it can only move along the guide slide due to the restriction of the guide slide.

[0009] The preferred technical solution is as follows: a guide positioning groove is provided on the movable block, and a guide shaft corresponding to the guide positioning groove is detachably provided on the support block. When the movable block moves forward a certain distance, the guide shaft is locked with one side of the guide positioning groove, restricting the movable block from moving further, thereby making the distance that the push plate pushes the nut to be installed into the deep cavity of the product always consistent.

[0010] Optimal technical solution: The number of push plates connected to the front end of the movable block is one or more, so that the movable block can simultaneously drive multiple push plates to perform nut delivery operations.

[0011] Preferred technical solution: The positioning block and the support block are both detachably arranged on the base through positioning pins. The positioning block and the support block can be quickly replaced and the position adjusted according to the product model, thereby improving the applicability of the device.

[0012] Preferred technical solution: The width of the guide groove is consistent with the distance between the opposite sides of the nut to be installed, which is used to limit the angle of the nut to be installed and ensure that the angle of the nut to be installed is consistent when entering the deep cavity of the product.

[0013] Preferred technical solution: The front end of the push plate is provided with a V-shaped groove for calibrating the nut to be installed. The V-shaped groove is engaged with the corners of the nut to be installed, thereby improving the stability of the push plate when pushing the nut to be installed.

[0014] Due to the application of the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0015] The utility model relates to a double-sided deep-cavity nut installation device, which uses elastic force instead of manpower to feed and install the nuts, thereby improving the consistency of the nut feeding accuracy; a slideway is used in conjunction with a push plate to guide and position the nuts during feeding, thereby improving the nut feeding efficiency; a guide shaft and a guide positioning groove are used in conjunction to limit the feeding depth of the nuts, thereby further ensuring the consistency of the nut feeding depth.

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] Example 1:

[0029] like Figure 1 As shown, a double-sided deep cavity nut mounting device disclosed in the present invention includes a base 1, a positioning block 2 and a support block 3 are provided on the base 1. The main components of the present invention are described in detail below:

[0030] like Figure 1 and Figure 2 As shown, the positioning blocks 2 respectively limit and fix the two ends of the product 6.

[0031] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the support block 3 is arranged on the side of the positioning block 2 away from the product 6; the support block 3 is provided with a guide groove 31 corresponding to the deep cavity on the product 6 for accommodating the nut 5 to be installed, and the width of the guide groove 31 is consistent with the distance from the opposite side of the nut 5 to be installed, so that the nut 5 to be installed maintains a uniform horizontal angle in the guide groove 31; a push plate 32 is slidably connected in the guide groove 31, and a V-shaped groove 32a is provided at the front end of the push plate 32. When the nut 5 to be installed is pushed, the V-shaped groove 32a is docked with the edge of the nut 5 to be installed, increasing the contact area between the push plate 32 and the nut 5 to be installed, and improving the stability of the movement of the nut 5 to be installed; the push plate 32 is connected to the side away from the product, and a spring 34 is also connected between the pull rod 33 and the support block 3, and the elastic force of the spring is used instead of manpower to drive the push plate 32, thereby improving the stability of the driving force.

[0032] References Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the usage method and principle of the double-sided deep cavity nut installation device of the utility model are as follows: when in use, pull the pull rod 33 outward to make the spring 34 generate a rebound force, and put the nut 5 to be installed into the guide groove 31. After loosening the pull rod 33, the push plate 32 pushes the nut 5 to be installed into the deep cavity of the product 6 under the action of the rebound force of the spring 34. The elastic force of the spring replaces manual pressing to avoid inaccurate positioning of the nut 5 to be installed due to excessive or insufficient pressing force.

[0033] Example 2:

[0034] like Figure 2 、 Figure 3 and Figure 4 As shown, in order to increase the stability of the movement of the push plate 32, a guide slide 35 is connected to the side of the guide groove 31 away from the product, and the push plate 32 and the pull rod are connected by a movable block 36. The movable block 36 is slidably set in the guide slide 35. The guide slide 35 limits the movable block 36 to move forward and backward only along the setting direction of the guide slide 35, so that the push plate 32 can only move forward and backward along its setting direction, thereby improving its movement stability and thus improving the installation accuracy of the nut 5 to be installed.

[0035] Example 3:

[0036] like Figure 2 、 Figure 3 and Figure 4 As shown, in order to further improve the installation accuracy of the nut 5 to be installed, a guide positioning groove 36a is provided on the movable block 36, and a guide shaft 37 corresponding to the guide positioning groove 36a is detachably provided on the support block 3. The guide shaft 37 limits the forward and backward movement distance of the movable block, thereby limiting the forward distance of the push plate 32, thereby avoiding poor positioning of the nut 5 to be installed due to the pushing depth exceeding the range.

[0037] Example 4:

[0038] like Figure 2 、 Figure 3 and Figure 4 As shown, in order to improve the applicability of the installation device, the positioning block 2 and the support block 3 are both detachably arranged on the base 1 through the positioning pin 4. When it is necessary to switch to different models of products 6, the processing switch can be achieved by replacing or adjusting the positioning block 2 and the support block 3.

[0039] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
