Description

Technical Field

[0001] This application belongs to the field of elevator manufacturing technology, and in particular relates to a drilling tool for a track support. Background Technology

[0002] Elevator rails guide the elevator's vertical movement, while rail supports securely mount the elevator rails within the elevator shaft. Their structure is as follows: Figure 5 As shown, the track support 7 is Λ-shaped and is formed by stamping and folding a steel plate at a 90-degree angle. Mounting holes 71 are provided on both sides of the track support 7. When the operator drills holes in the track support 7, they only use a clamping fixture to hold and fix one side of the track support 7. The fixing effect is poor, causing the track support 7 to vibrate easily during drilling, thus affecting the drilling accuracy. Utility Model Content

[0003] To address the shortcomings of the prior art, this application provides a drilling fixture for track supports, which can effectively fix the track supports and improve drilling accuracy.

[0004] To achieve the above objectives, the present invention employs the following technology:

[0005] A drilling fixture for a track support includes:

[0006] A drilling fixture for a track support includes:

[0007] A substrate having a pair of slide rails arranged along its length;

[0008] The mounting plate is slidably fitted onto the slide rail and is set parallel to the base plate. Guide posts are provided at both ends of the top surface of the mounting plate.

[0009] A Λ-shaped plate with horizontal support plates extending outward from both bottom edges. The support plates slide through the corresponding guide columns. The edges of the Λ-shaped plate face upward and both plate surfaces have through holes.

[0010] Two strip plates are parallel to the two surfaces of the Λ-shaped plate, and one side of each strip plate is connected to the top surface of the corresponding support plate. The strip plates are located above the corresponding through holes.

[0011] The pressure block is located on the mounting plate and directly below the Λ-shaped plate. Its top surface has pressing parts on both sides, which are used to enter the corresponding through holes and cooperate with the corresponding strip plate to fix the track bracket.

[0012] The pressure plate is positioned above the Λ-shaped plate, moving along the height of the base plate. A mating groove is provided at its bottom to engage with the Λ-shaped plate to fix the track support.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By setting up the pressure plate and the mating groove, and by cooperating with the track support and the Λ-shaped plate, the track support can be pressed tightly onto the Λ-shaped plate. At the same time, the downward pressure of the pressure plate will press the track support onto the pressing part, thereby fixing the track support from multiple points, greatly reducing the vibration of the track support during drilling and ensuring drilling accuracy.

[0015] 2. By setting a spring, after each drilling is completed, the Λ-shaped plate will automatically rise along the guide post under the action of the spring, so that the strip plate separates from the pressing part, so as to facilitate the installation of the next track bracket, effectively improving the installation efficiency of the track bracket, and thus improving the drilling efficiency.

Detailed Implementation

[0022] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0023] This application provides a drilling fixture for a track support, such as... Figures 1-5 As shown, it includes: substrate 1, mounting plate 2, Λ-shaped plate 3, two strip plates 4, pressure block 5, pressure plate 6, etc.

[0024] The substrate 1 is provided with a slide rail 11 facing the length direction of the substrate 1; the mounting plate 2 is slidably fitted on the slide rail 11 along the length direction of the substrate 1, the mounting plate 2 is arranged parallel to the substrate 1, and the top surface of the mounting plate 2 is provided with guide posts 21 at both ends.

[0025] like Figures 1-3 As shown, both bottom edges of the Λ-shaped plate extend outward with horizontal support plates 31. Each support plate 31 is vertically and slidably inserted into the corresponding guide post 21. The edges of the Λ-shaped plate face upward, and both surfaces of the Λ-shaped plate 3 have through holes 32.

[0026] like Figures 1-3 As shown, the two strip plates 4 are parallel to the two surfaces of the Λ-shaped plate 3, and one side is connected to the top surface of the corresponding support plate 31. The strip plates 4 are located above the corresponding through holes 32. The track support 7 is used to pass through the two surfaces of the strip plates 4 and the Λ-shaped plate 4.

[0027] like Figure 2 and Figure 4 As shown, the pressure block 5 is located on the mounting plate 2 and directly below the Λ-shaped plate 3. Its top surface has pressing parts 51 on both sides, which are used to enter the corresponding through hole 32 and cooperate with the corresponding strip plate 4 to fix the track bracket 7.

[0028] like Figure 1 and Figure 2 As shown, the pressure plate 6 is positioned above the Λ-shaped plate 3 along its length and is movable along the height direction of the substrate 1. A gantry frame 13 is mounted on the substrate 1, with its top parallel to the substrate 1 and a linear mechanism 14 fixedly installed thereon for driving the pressure plate 6 to move along the height direction of the substrate 1. A mating groove 61 is provided at the end of the pressure plate 6 along the length direction of the Λ-shaped plate 3. The mating groove 61 is V-shaped with its opening facing downwards, and the angle formed inside the mating groove 61 is ninety degrees.

[0029] In application, the operator operates the linear mechanism 14 to move the pressure plate 6 upward until it is completely separated from the Λ-shaped plate 3. Then, the mounting plate 2 is pulled to remove the gantry frame 13 along the slide rail 11. The operator holds the Λ-shaped plate 3 and lifts it along the guide post 21 until the strip plate 4 separates from the pressing part 51. Then, the track bracket 7 to be drilled is inserted from one end of the Λ-shaped plate 3 between the two surfaces of the strip plate 4 and the Λ-shaped plate 3. The two surfaces of the Λ-shaped plate 3 are respectively attached to the two surfaces of the track bracket 7, and the two strip plates 4 are also respectively attached to the two surfaces of the track bracket 7.

[0030] like Figure 1 and Figure 2As shown, the entire track support 7 is installed between the two surfaces of the strip plate 4 and the Λ-shaped plate 3. The Λ-shaped plate 3 is then released, and under the action of gravity, it falls along the guide post 21. The two surfaces of the track support 7 abut against the corresponding pressing parts 51. The mounting plate 2 is then pushed back under the pressure plate 6, so that the two inner sides of the mating groove 61 are parallel to the two surfaces of the Λ-shaped plate 3. The linear mechanism 14 drives the pressure plate 6 to move down, and the two inner sides of the mating groove 61 abut against the two surfaces of the track support 7, pressing the track support 7 firmly onto the Λ-shaped plate 3. At the same time, due to the downward pressure of the pressure plate 6, the strip plate 4 presses the two sides of the track support 7 onto the pressing parts 51, thereby fixing the track support 7 from multiple points, greatly reducing the vibration of the track support 7 during drilling, and ensuring drilling accuracy. At this time, the operator holds the drilling machine, and the drill bit passes through the through hole 32 to complete the drilling operation.

[0031] Specifically, such as Figure 1 and Figure 2 As shown, each guide post 21 is fitted with a spring 22. The spring 22 is connected between the support plate 31 and the mounting plate 2. When the spring 22 is in its natural state, the strip plate 4 is separated from the pressing part 51. The advantage of setting the spring 22 is that after each hole is drilled for a track bracket 7, the pressure plate 6 moves upward, and the Λ-shaped plate 3 will automatically rise along the guide post 21 under the action of the spring 22, so that the Λ-shaped plate 3 is separated from the pressing part 51. In this way, the installation of the next track bracket 7 can be carried out directly without having to lift the Λ-shaped plate 3 first, which effectively improves the installation efficiency of the track bracket 7 and thus improves the drilling efficiency.

[0032] Preferred, such as Figure 1 and Figure 4 As shown, there are four guide posts 21, which are located at the four corners of the mounting plate 2. Each support plate 31 is inserted through the corresponding guide post 21. The guide posts 21 are evenly distributed, which can effectively ensure the smooth movement of the Λ-shaped plate 3 along the guide post 21 and avoid interference in the movement of the Λ-shaped plate 3.

[0033] Specifically, such as Figure 2 As shown, each time the mounting plate 2 is pushed back, the Λ-shaped plate 3 can quickly move to the underside of the pressure plate 6. A positioning block 15 can be set on the base plate 1. When the mounting plate 2 is pushed back until its other end abuts against the positioning block 15, the Λ-shaped plate 3 is located directly under the pressure plate 6, which further improves drilling efficiency.

[0034] Specifically, such as Figure 1 and Figure 2As shown, one end of the mounting plate 2 has a pin hole 23, and the base plate 1 has a positioning hole 12. When the other end of the mounting plate 2 abuts against the positioning block 15, the Λ-shaped plate 3 is located directly below the pressure plate 6. The pin hole 23 and the positioning hole 12 are coaxial. Then, the pin 24 is inserted into the pin hole 23 and the positioning hole 12 to fix the mounting plate 2. This can effectively prevent the mounting plate 2 from shifting along the slide rail 11 when the pressure plate 6 is pressed down, thereby affecting the fixing effect of the track bracket 7 and effectively improving the reliability of the tooling for fixing the track bracket 7.

[0035] Preferred, such as Figure 2 and Figure 4 As shown, the pressure block 5 is rectangular and is parallel to the mounting plate 2 in the width direction of the base plate 1. The two corners on the top surface of the pressure block 5 are beveled to form the pressing part 51. The two bevels are parallel to the bottom surface of the corresponding strip plate 4. The bevels cooperate with the strip plate 4, and the pressing area with the track bracket 7 is larger, which has a better fixing effect.

[0036] Preferred, such as Figure 1 and Figure 2 As shown, the slide rail 11 includes a pair of oppositely oriented grooved tracks. Multiple pulleys are arranged along the length direction on both sides of the mounting plate 2. The rotation axis of the pulleys is oriented towards the width direction of the mounting plate 2, and the pulleys slide in the grooved tracks.

[0037] The above description is only a preferred embodiment of this application and is not intended to limit this application. Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application.
