Description

Technical Field

[0001] The utility model relates to the technical field of a fixture, in particular to a drilling fixture for a baking oven workbench apron. Background Art

[0002] At present, the apron on the workbench of a baking oven (usually a 36-inch pellet oven) is generally a 36-inch apron, which is the upper 36-inch apron. The production process of the aluminum apron is to form an aluminum casting through a die-casting machine, and then carry out inlet processing and drilling processing on the aluminum casting to complete the manufacture of the apron. As Figure 10 and Figure 11 shown, the structure of the apron is generally in a square frame shape and the front end is in an unclosed semi-enclosed structure, that is, there are only three plates on the apron (only on the two side faces and the back face) and no plate is provided at the front end. And a skirt 23 extending horizontally outwards is provided at the bottom of the apron, and a plurality of mounting holes 24 need to be drilled on the skirt. There is an inlet 25 at the top, and the apron is fixedly installed on the baking oven through the installation of the mounting holes and screws. After the aluminum-cast apron is die-cast and formed, the inlet and drilling processing are generally carried out by manual grinding and manual drilling. Such a processing method has some problems, specifically as follows: (1) Since the aluminum casting of this apron is large, there are many inlets and about 16 mounting holes need to be drilled. If manual grinding is used to grind the water inlet of the inlet, it will take a long time and the surface is difficult to grind flat. Drilling is also very cumbersome, resulting in a long processing time, unsatisfactory effect, high cost and unstable quality. (2) When drilling and inlet processing the apron, the apron needs to be clamped and fixed accordingly to facilitate processing and prevent the apron from shifting. However, in the prior art, there is no special fixture device or equipment for processing the apron structure. Instead, after clamping one surface, processing is carried out on this surface, and the other surfaces cannot be clamped simultaneously; accurate processing of overall clamping cannot be achieved and the safety risk is increased during processing.

[0003] Therefore, it is necessary to make certain improvements to the apron processing technology for the baking oven workbench in the prior art to improve the problems of the above prior art. Summary of the Invention

[0026] Embodiment 1

[0027] A drilling fixture for a baking oven workbench described in this Embodiment 1, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 12 shown, includes a tooling fixture drilling platform 1, a drilling fixture fixing plate 2 erected and installed on the tooling fixture drilling platform and distributed in an I-shaped manner, a quick horizontal presser 3 installed on the tooling fixture drilling platform and corresponding to the two outer sides of the drilling fixture fixing plate, a side pressing cylinder assembly 4 installed on the tooling fixture drilling platform and corresponding to the two outer sides of the drilling fixture fixing plate, and five back pressing cylinder assemblies 5 installed on the tooling fixture drilling platform and evenly arranged corresponding to the back of the drilling fixture fixing plate; the side pressing cylinder assembly and the back pressing cylinder assembly are both connected with cylinder supply air pipes; the side pressing cylinder assembly includes a side pressing cylinder 6 and a side pressing plate 7 installed at the air rod end of the side pressing cylinder and facing the outer side of the baking oven workbench apron 22 to be pressed; the back pressing cylinder assembly includes a back pressing cylinder 8 and a back pressing plate 9 installed at the air rod end of the back pressing cylinder and facing the outer side of the back of the baking oven workbench apron to be pressed.

[0028] After the aluminum casting of the oven workbench apron is die-cast, place the oven workbench apron into the gap between the back pressing cylinder assembly and the back of the drilling fixture fixing plate, and into the gap between the side pressing cylinder assembly and the outside of the drilling fixture fixing plate. When placing the oven workbench apron, the gap between the back pressing cylinder assembly and the back of the drilling fixture fixing plate is relatively large. The back of the oven workbench apron should be as close as possible to the back pressing cylinder assembly, so that when the oven workbench apron is placed, its skirt will not collide with the quick horizontal presser, making it difficult to place, or the quick horizontal presser will not impede the placement of the oven workbench apron. After the oven workbench apron is placed, gently push it forward and squeeze it slightly, so that the side and back of the oven workbench apron are respectively in close contact with the side and back of the drilling fixture fixing plate. Then press down the quick horizontal presser to clamp the skirt of the oven workbench apron. Then start all the side pressing cylinders and back pressing cylinders, so that the side pressing plate and the back pressing plate clamp the side and back of the oven workbench apron, and the oven workbench apron can be clamped on the drilling fixture fixing plate for milling and drilling. During processing, the machine tool and drill bit of the CNC machining center perform CNC processing. After processing is completed, the drill bit of the CNC machining center resets and stops, and all the side pressing cylinders and back pressing cylinders also reset and stop. Then the oven workbench apron can be taken out to complete the drilling process. All the side pressing cylinders and back pressing cylinders are controlled to start and stop by CNC programming, so as to control the clamping and loosening of the oven workbench apron.

[0029] In the first embodiment, as Figure 8 and Figure 9 shown, the quick horizontal presser includes a presser fixing base 15 fixedly installed on the drilling platform of the tooling fixture, a presser rotating seat 16 hingedly installed with the presser fixing base and capable of rotating up and down, a presser arm 17 installed at one end of the presser rotating seat, and a presser handle 18 installed at the other end of the presser rotating seat. When the quick horizontal presser is pressed, hold the presser handle and lift it up, then the presser arm will press down and press against the skirt of the oven workbench apron to achieve the pressing effect.

[0030] In the first embodiment, the presser fixing base is provided with a base slot 19 from top to bottom at the middle position. An insert 20 is provided in the presser rotating seat and is pressed into the base slot and gradually forms a tight fit. The end of the presser arm is sleeved with a wear-resistant pressure head 21 that can press down the oven workbench apron, and the presser handle is inclined upward. The base slot is provided with a press-in channel that is wider at the top and narrower at the bottom, and the outside of the insert is also sleeved with a wear-resistant rubber head. When the insert is pressed down and enters the press-in channel, it will gradually tighten. The deeper it is pressed down, the greater the pressure of its press-in. This can achieve the effect that when the wear-resistant pressure head presses the skirt of the oven workbench apron, it is not easy to be triggered and lifted. Only when the presser handle is pressed down can the plug be disengaged from the press-in channel to achieve the loosening effect.

[0031] In the first embodiment, the side pressing cylinder is fixedly installed on the side of the drilling platform of the tooling fixture through the side pressing cylinder bracket 10; the back pressing cylinder is fixedly installed on the back of the drilling platform of the tooling fixture through the back pressing cylinder bracket 11.

[0032] In the first embodiment, a side pressing cylinder pipe joint 12 for connecting with the corresponding cylinder air supply pipe is fixedly installed on the side pressing cylinder; a back pressing cylinder pipe joint 13 for connecting with the corresponding cylinder air supply pipe is fixedly installed on the back pressing cylinder. By connecting the cylinder air supply pipe through the corresponding pipe joint and supplying air, the normal operation of the side pressing cylinder and the back pressing cylinder is realized.

[0033] In the first embodiment, both the side pressing cylinder and the back pressing cylinder are double-axis double-rod cylinders.

[0034] In the first embodiment, a waste discharge opening 14 for discharging waste is further provided on the drilling platform of the tooling fixture within the range surrounded by the drilling fixture fixing plate. After the baking oven workbench apron is processed and taken out, the waste generated during processing can be manually swept to the waste discharge opening by a brush or the like, thereby completing the cleaning and collection of the waste and ensuring the cleanliness of the machine tool during the processing of the next baking oven workbench apron.

[0035] The drilling fixture for the baking oven workbench apron uses a special fixture to perform one-time all-round fixing and clamping on the baking oven workbench apron without manual fixing, and then cooperates with the machine tool of the CNC machining center to perform inlet and outlet milling and drilling on the baking oven workbench apron, etc., to achieve the purpose of one-time processing of the baking oven workbench apron; it has the advantages of short processing time, high processing accuracy, one-time clamping and processing, no need for secondary clamping and repeated processing, low cost, good and stable quality, improved efficiency and safety performance, and can save manpower and cost.

[0036] The above is only a preferred embodiment of the present invention, and does not impose any form of limitation on the structure of the present invention. Any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
