Description

Technical Field

[0001] This utility model belongs to the field of electrical installation auxiliary tools, and in particular relates to a precision sheet metal equipment wire trough installation and positioning fixture. Background Technology

[0002] Electrical cabinets typically require drilling holes to match the mounting holes on the cable trays to ensure the stability and safety of the cable trays when installed on the electrical cabinet.

[0003] In practice, there are often some problems with positioning and drilling holes for electrical cabinets. Traditional drilling methods rely mainly on the worker's experience and visual inspection for positioning, which can easily lead to inaccurate drilling positions, affecting the installation quality and aesthetics of the cable trays. Furthermore, differences in the skill levels of different workers can cause inconsistencies in drilling positions, increasing construction errors and rework rates.

[0004] Therefore, there is an urgent need for a precision sheet metal equipment cable tray installation and positioning fixture that can assist operators in quickly and accurately drilling and positioning holes in electrical cabinets. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a precision sheet metal equipment wire trough installation and positioning fixture, which can accurately and quickly drill and position the positions on the electrical cabinet for installing wire troughs, improve the quality and efficiency of wire trough installation, and reduce construction errors and rework rates.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a precision sheet metal equipment wire groove installation and positioning fixture, including a vertical ruler with a scale, a positioning seat slidably connected to the vertical ruler along the direction of the scale, a pointer that corresponds to the scale on the positioning seat, and a punching guide whose center can be collinear with the pointer and the scale on the positioning seat.

[0007] The ruler has feet at both ends that can fit against the electrical cabinet, and the feet have mounting holes.

[0008] The ruler has several through holes corresponding to the scale, and a positioning pin that can be inserted into the positioning seat is movably inserted in the through hole.

[0009] Optionally, a rubber sleeve is provided around the outer periphery of one end of the positioning pin that is inserted into the positioning seat, and the rubber sleeve can elastically support the positioning seat and the positioning pin.

[0010] Optionally, one end of the locating pin is in the shape of a semi-circular ring.

[0011] Optionally, the positioning seat is slidably mounted on the ruler via a linear guide rail.

[0012] Optionally, the ruler and the support legs form a U-shaped structure, and the punching guide can move linearly at the opening of the U-shaped structure.

[0013] Optionally, the support legs are provided with magnets that can be magnetically attached to the electrical cabinet.

[0014] Optionally, the support legs are equipped with suction cups that can be attached to the electrical cabinet.

[0015] Optionally, a steel wire rope is provided between the positioning pin and the positioning seat.

[0016] Compared with existing technologies, the beneficial effects achieved by this utility model are as follows: the legs at both ends of the ruler can fit against the electrical cabinet and can be fixed to the electrical cabinet through the mounting holes, allowing the positioning fixture to be stably installed on electrical cabinets of different shapes and sizes, increasing the applicability and versatility of the positioning fixture. Furthermore, by aligning the indicator on the positioning seat with the scale on the ruler, the specific value of the drilling position on the scale can be accurately determined, making the drilling position more accurate and greatly reducing errors caused by manual visual inspection or rough measurement. At the same time, operators can quickly and intuitively adjust the position of the positioning seat according to the scale without performing complex measurements and calculations. Subsequently, the positioning pins that are movably inserted on the ruler can be used to fix the positioning seat after it has been adjusted to the required position, ensuring that the positioning seat will not move during the drilling process, thus improving the stability and reliability of manual operation.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0023] It should be noted that if directional indicators (such as up, down, bottom, top, etc.) are involved in this embodiment, these directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. Unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances. Example 1

[0024] like Figures 1-3 As shown, a precision sheet metal equipment wire trough installation and positioning fixture includes a ruler 1 with a scale 101. A positioning seat 2 is slidably connected to the ruler 1 along the direction of the scale 101. The positioning seat 2 is provided with an index mark 201 that corresponds to the scale 101, and a drilling guide 3 is provided on the positioning seat 2, whose center is collinear with the index mark 201 and the scale 101. The drilling guide 3 is existing technology and can provide a positioning basis for the drilling tool. The operator can determine the position of the drilling guide 3 by using the scale 101 on the ruler 1 and the index mark 201 on the positioning seat 2, thus meeting the positioning requirements for drilling at different intervals.

[0025] As described above, the ruler 1 has legs 4 at both ends that can fit against the electrical cabinet. Each leg 4 has a mounting hole 401. The operator can pre-drill a hole in the electrical cabinet for installing a cable tray, and then use bolts or other fasteners to partially fix one leg 4 of the positioning fixture to the pre-drilled hole in the electrical cabinet. Then, using this hole as the rotation center, the entire positioning fixture is rotated. Once the positioning fixture is in the appropriate position, the mounting hole 401 on the other leg 4 is used as a positioning guide for drilling, and drilling is performed again. Then, bolts or other fasteners are used to fix the other leg 4 to the electrical cabinet, and the bolts on the other leg 4 are tightened. At this point, the positioning fixture is completely fixed to the electrical cabinet. The ruler 1 has several through holes 102 corresponding to the scale 101, and positioning pins 5 that can be inserted and engaged with the positioning seat 2 are movably inserted into the through holes 102. By inserting and removing the positioning pin 5, the operator can limit the positioning seat 2 to any position within the scale 101, thus meeting the operator's need to position the drilling position using the positioning guide.

[0026] The precision sheet metal equipment cable tray installation and positioning fixture in this technical solution includes, but is not limited to, the ability to drill and position electrical cabinets, and can also be used for opening holes in cable trays.

[0027] Furthermore, to ensure a tight fit between the positioning pin 5 and the positioning seat 2, such as... Figure 2 , Figure 3 As shown, a rubber sleeve 501 is provided on the outer periphery of the end of the positioning pin 5 that is inserted into the positioning seat 2. The rubber sleeve 501 can elastically support the positioning seat 2 and the positioning pin 5. The rubber sleeve 501 can increase the friction between the positioning seat 2 and the positioning pin 5. Without external force, the positioning pin 5 will not detach from the positioning seat 2.

[0028] Furthermore, such as Figure 3 As shown, one end of the positioning pin 5 is semi-circular, making it easy for operators to pull the positioning pin 5 out of the positioning seat 2 and the ruler 1. Meanwhile, to prevent the positioning pin 5 from being accidentally lost, a steel wire rope can be installed between the positioning pin 5 and the positioning seat 2.

[0029] In this embodiment, to increase the accuracy of the linear motion of the positioning seat 2, the positioning seat 2 is slidably mounted on the ruler 1 via a linear guide rail 6. The linear guide rail 6 is existing technology and has a high-precision guiding function.

[0030] Meanwhile, in this technical solution, to facilitate the operator's observation of the drilling progress, the ruler 1 and the support leg 4 are arranged to form a U-shaped structure, and the drilling guide 3 can move linearly at the opening of the U-shaped structure. Example 2

[0031] Building upon Example 1, for electrical cabinets made of magnetically adsorbable metal, magnets can be installed on the support legs 4 to allow the positioning fixture to be quickly fixed to the cabinet, facilitating operator use. Simultaneously, for electrical cabinets that cannot be magnetically adsorbed, suction cups can be installed on the support legs 4 to adhere to the cabinet. These suction cups are existing technology, including but not limited to vacuum pump suction cups or manual vacuum suction cups. When attached to the electrical cabinet, air can be extracted between the suction cup and the cabinet to ensure a tight adhesion. Using this method to fix the positioning fixture to the electrical cabinet is convenient and has a wide range of applications.

[0032] Working principle: First, the operator can pre-drill a hole in the electrical cabinet for installing the cable tray. Then, using bolts or other fasteners, one of the support legs 4 of the positioning fixture is partially fixed to the pre-drilled hole in the electrical cabinet. The positioning fixture is then rotated around this hole as the rotation center. Once the positioning fixture is in the appropriate position, the mounting hole 401 on the other support leg 4 is used as the positioning guide for drilling. Drilling is then performed again. The other support leg 4 is then fixed to the electrical cabinet using bolts or other fasteners, and the bolts on the other support leg 4 are tightened. The operator can determine the position of the drilling guide 3 using the scale 101 on the ruler 1 and the indicator 201 on the positioning seat 2, meeting the guidance requirements for drilling at different intervals and improving accuracy. By inserting and removing the positioning pin 5, the operator can limit the positioning seat 2 to any position within the range of scale 101, meeting the requirement of fixed-distance drilling.

[0033] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
